I was just wondering, when analogue television is switched off in the UK,
what are the old analogue transmitters going to be used for? Surely they
could perhaps modify the existing analogue transmitters so they can transmit
digital signals instead, which will open up digital TV to a lot more people.
As I understand it, there is thousands of analogue transmitters around the
country, and less than a hundred digital transmitters. If the government
wants digital TV to take off they really need to consider the thousands of
people that are completely unable to receive any kind of digital signal.
So what will happen to the old transmitters? Will be interesting to find
out.

Its possible and they could certainly retain existing parts like masts and
power supplies. Converting analogue transmitter electronics into digital
transmitter electronics is rather like converting a gas cooker to electric.
Therefore most analogue equipment will end up in the scrapyard unless it is
left in situ if extra space is not required. BT sometimes did this with their
old exchanges to save money. Most of the strowger in Romford exchange is still
in place.

Satellite and cable. IMO there is little point in bothering with digital
terrestrial apart from local short range broadcasting.

At the rate at which things are going analogue television will never be
switched off. After all is there a real need to free up the spectrum for
anything ?
There are simply too many old fogeys who lovingly polish their 1976 Decca and
stubbornly refuse to involve themselves in digital technology.
Yes... the spectrum is needed for a decent digital network, how about 8K
SFN's with a shared local mux?

As far as I know, the spectrum currently used by analogue TV was sold
off by the Labour government a couple of years ago for "mobile phone
usage". It was mysteriously snapped up by BT at a cost of billions,
plunging BT into debt and allowing the government to pay off large
chunks of the national debt - something they're always glad to boast
about it seems.
There are two obvious problems with this:
1. There are already more mobile phones than there are *people* in the
UK, so I don't really see why there should ever be a need for more
airspace for them than there is already.
2. Digital terrestrial TV doesn't work properly! So unless people want
to put up with constant picture freezes, they will either have to get
cable or satellite TV and alot of people won't want either of those.
Jamie.
The 3G frequencies that sold for £25b are in and around ~2000MHz, which is
quite a bit above the UHF broadcast spectrum.

Some people are luddites. VHF 405 line broadcasts were switched off and few complained so why not analogue UHF as
well.
There is a big difference. 625 was far better quality than 405, and it
had colour. Digital is of vastly inferior quality to analogue - hence
the resistance.

Is it really ? Can you justify this statement ?
I would argue that, under equivalent reception conditions, digital is as good
as, if not better than analogue. Please remember that digital transmissions
are much lower in power and most often it's people in fringe reception areas
that complain when they can't get perfect digital pictures. If you are
receiving digital transmissions at the same signal strength as good analogue
ones and you still get inferior quality, then you have a serious problem with
your installation.
The only reason I watch digital television is if there is a widescreen
programme being broadcast. The bitrates used by the BBC and ITV on their
multiplexes are so low that I revert to watching by analogue for 4:3
programming.

Sorry - bit of a major generalisation there. Can't agree with it.
Digital broadcasts are capable of excellent pictures - with the benefits of
component colour rendition, a clean luminance path and anamorphic 16:9
pictures. All of these are major advantages over analogue PAL / NTSC /
SECAM.
Digital transmissions can be poor, analogue transmissions can be poor.
Good digital transmissions, in my opinion, are better than good analogue
when it comes to the final viewed picture.
I find it difficult to watch PAL analogue now, the 12F12/14L12 picture shape
and chroma subcarrier artefacts are increasingly annoying to me.
Steve
Is digital terrestrial really needed as a replacement for analogue terrestrial ? I still can't see what is wrong with
satellite or cable.
IMO satellite dishes look a darn sight neater than UHF aerials. Infact if satellite dishes were around 40 years ago
and Yagi aerials were invented today they would probably be banned by most councils for being visually obtrusive.
I get a reasonable analogue picture on all channels from Crystal Palace here
in Windsor. However after spending £170 on a new aerial and pole my digital
signal is still poor. There are two tower cranes almost in line of site
between me and the transmitter.
These seem to be causing some of my problems. The C5 mux often is
unwatchable with many seconds of frozen or blank screen.
Given the choice of slightly noisy and reflective analogue pictures and
blocky freezing digital pictures, which one would you choose?
At 30 miles from Crystal Palace I don't think this can be classed as a
fringe area.
Ashley
I'm speaking from the point of view of an engineer who has designed
and installed several TV networks (Hong Kong, the middle East) in both
analogue and digital formats. I can judge picture quality on the
normal CCIR scale to an accuracy of +/- .2 most of the time on an
analogue picture by eye. My TV at home runs from an antenna with good
line-of-sight to Crystal Palace - and no ghosts. I need to attenuate
the signal to prevent intermodulation. PAL I, when it is good, is
about as good as you can get.
Certainly the quality of the analogue signal has deteriorated over the
last few years, but that has happened as a result of the amount of
digital processing in the signal path. Certainly most sports have
suffered dreadfully - cricket balls disappearing when they are hit,
racing cars leaping across the screen in a series of jumps. These are
all obvious digital artefacts that everybody in the industry accepts -
and they didn't happen with analogue.
As for the "last mile" home delivery, compression means that a great
deal of fine detail has disappeared. Primary signal processing has
caused that. When compressing, you need a disproportional amount of
data to provide it, so you don't get it. Also, for reasons I can't
understand, there is a constant soup of noise behind digital pictures.
Finally, probably in an attempt to recover some sharpness, all the
digital pictures I have seen exhibit what looks very much like ringing
around edges.
Things will of course never improve. The pressure is on (in digital
radio as well) to cram more programmes into the multiplexes. That
means a constant downward spiral of quality.
But I have to say most people don't care. Look at the average analogue
TV in the average house and there will be ghosts; the colour control
will be wound up to just short of luminous. So people get pretty much
what they deserve. Maybe digital will suit them after all.
It is not possible to watch good digital TV in the UK, because
everything is compressed to the point where it is far inferior to
analogue.
Admittedly, given a viewing location where analogue reception is poor,
digital will be better. But that is not exactly saying much for
digital.
Then where would all the pigeons sit?
Not in ours there isn't. The best piccys we get are still on analogue
and this from ITV Anglia when its local output, and the local Narwich
BBC the rest of the time I swear our TV is more worthy than what its
being fed with!...

I agree. But analogue TV is all sourced from MPEG digital feeds anyway
now so there isn't much diffence - they both look awful.
Thank goodness for German satellite TV :-)
Jamie.
On analogue satellite? Doesn't the FM noise on the chroma get on your
nerves - especially with those lovely German super-chroma pictures :-)
(Analogue satellite = FM vision modulation. FM modulation has a triangular
noise spectrum - meaning more noise on the higher frequencies than lower -
meaning the relatively HF PAL subcarrier is much noisier than would be the
case on terrestrial AM - hence analogue PAL satellite often suffers from
noisy chroma. I certainly wasn't impressed with analogue satellite
transmissions on a reasonably high-spec Echostar system a few years back)
Steve
>
>Jamie.
Nowhere near as much as MPEG artefacts do, although I recognize that
it doesn't look as good as the "proper" terrestrial PAL transmissions
in the UK used to.
The main problem is that German isn't my first language, but I do know
enough to get by when we go there on holiday.
The increased sharpness, detail and life-like tracking of movement far
makes up for the slight grain and combing. And the latter isn't half
as pronounced as a UK pal->mpeg->pal converted transmission, which
ends up having combing added twice over. We've had this conversation
before... :-)

It is interesting to see that different people find different artefacts
annoying. Same arguments seem to apply with 100Hz TVs. I can't watch the
things (even the latest Sonys look better to me in DRC50 not DRC100) - yet
other people swear by them!
I will agree that PAL->MPEG->PAL is horrid - and I don't much like
PAL->MPEG->RGB. Where I enjoy digital is YUV->MPEG2->RGB where there is no
PAL at all! But as you say - we've had this conversation before!
Steve
>Jamie.
Putting the MPEG2 quality discussions aside, what about our poor 2K COFDM
encoding, now that genuinely is annoying, is it really acceptable that
people should get picture freezes every time somebody switches on a
fluorescent light or the central heating pump kicks in (or even the
neighbours heating in some cases), as long as we have 2K the DTV system will
appear inferior in terms of robustness compared to PAL. Of course people
will argue that a new aerial and double-screened cable will sort that out,
however if people get perfectly good PAL pictures and then switch to DTT and
suffer all the electrical impulse problems with 2K, it's not really a good
argument.
The MUSICAM sound can quite clearly be heard to be inferior to NICAM and
even destroys matrixed surround sound, yet they have no discrete
multichannel system to replace it, nor are they planning one.
Also, Teletext is old and slow but very useful, MHEG is new and slow and
completely hopeless and carries little content, it's certainly not a clear
improvement. Who on earth thought a multilayered menu system could
completely replace a simple three digit number system.
How about a PDC replacement? I'm hoping that's just a short-term absence
until the EPG's and digital recording is perfected for consumer products.
Our DTT system was rushed and it's clearly rough round the edges.

a former BBC Director General wrote, in his autobiography, "The British

He was referring to the "great wavelength changes" of 1978, but I'm sure
it still applies.
Some landlords ban dishes, portables don't work with them and there are
places where it is impossible to receive from satellite.
Agreed - and call me paranoid - but I'd prefer my TV to be available
independent of a satellite network operated by a company based in
Luxembourg, and encrypted / EPGed using a proprietary system operated by a
commercial company.
I think we do have to find a way of making DTT work if we are to switch off
analogue - DCab and DSat are nice additions - but not replacements for
terrestrial free-to-air transmissions.

I wonder what would happen if Bin Laden's cronies decided to blow-up
Betzdorf? Can the Astra satellites be controlled and uplinked from another
site just in case something like this were to happen? Do they have
contingency (sp?) plans for things like this? I guess Eutelsat would have a
field day!
I was under the impression that UK broadcasters uplinked to Astra from
Crawley Court?
Certainly, Astra Analogue used to have a showreel running on their empty
transponders (probably going back about 10 years now). They definitely
mentioned a uplink station in London, as well as many other European major
cities.
Quite whether the satellites could be 'controlled' from these locations or
not, I'm completely unaware.

There are, and IMHO always will be, more places that cannot receive
an adequate DTT signal. I cannot see in this new 'market' driven world
the same effort going into providing DTT to "100%" of the UK popoulation,
as has been the case with analogue TV transmissions.

Add that to the fact that all it would take is a bit of space debris is hit one
or
more of the Astra satellites and it's "goodbye". Mind you I'm much more worried
by a slightly larger rock hitting the ground, then it's "goodbye everyone". I've
been watching too many Horizon/Equinox programmes again :-(
Astra have a 'standby' uplink site, somewhere else. Most UK channels
are uplinked by either Sky from their site near Southampton, or NTL from
sites at Winchester, Croydon, and Newman St W1.

There were similar problems/concerns when the switchover from 405
to 625 occured. I've seen 'pre-launch' documentation of the 625 service
which claimed that the coverage from the transmitters would be equivelent
to that of the 405 line services. Unfortunetely this didn't take into account
the higher frequencies, line of sight required to get a good, non-ghosting
picture and hence the need for all the additional relays.
DTT seems to be suffering from a similar problem...

Like where ? The Scottish Highlands require large dishes and can't access

I use ITV Digital myself, and I think its great and have no serious
complaints about it. But to get DTT, you have to be in a good coverage
area.. something many people arent. Thats why I think the best thing they
could do with the analogue transmitters is to either convert them to
digital, or at least try and put a few more digital transmitters in they're
place.

According to the satellite installers, approximately 20% of of households who
apply for a satellite dish cannot have one because they do not have a clear
line-of-sight path in the appropriate direction.
In fact, you are more likely to be able to receive satellite in the Scottish
Highlands than in the middle of London !
Please make sure you have your facts right !

Only a small proportion of society live in listed buildings. Most are country
mansions.
Ummm....
Like if you are stuck right below a mountain, large hill of cliff to the
south of you (Scottish Glens, parts of Bath and some Exmoor villages have
been mentioned).
You have a nearby tower block in the wrong place
You only have access to a north facing wall
You live in a conservation area (where, for example, you are only allowed a
TV aerial inside your roofspace)
You have a basement flat
You live just to the north of a flyover or railway embankment, especially
when large vehicles go over.
You live in a wood, or just to the north of one.
Your neighbour grows those Laylandia (or whatever) shrub trees in his hedge.
You live at the end of a runway with Jumbo Jets blotting out the satellite
every 2 minutes.
*******
Seriously, someone has done a calculation to show that only a maximum of
90ish% of the population could use a satellite dish even if they wanted do
(and I think this even included places that could if they installed a shared
dish). So in order not to disinfranchise people you need alternatives.
Colin
8k may not solve it. The interleave period is probably too short, and that's
the same on 8k as 2k.
J
Yes, but not if you are not connected to a fixed dish and have mains
electricity around to drive the satellite receiver.

In our village most of the listed buildings are small cottages. There are
some mansions, but they are modern.
>8k may not solve it. The interleave period is probably too short, and
>that's the same on 8k as 2k.
I think I was told that the main advantage of 8k is better immunity to ghost
signals (i.e. multipath signals that are reflected off large buildings,
etc). Since each digital bit stays at the same level before changing for
four times as long, something like 28us rather than about 7us with 2k, then
later reflected signals that arrive during this time are less likely to
corrupt the signal. Not sure about immunity to impulse noise though, maybe
someone can explain that.
I think there's an interesting senario developing. The government wants to
switch off analogue as soon as possible as it can smell the $$$ it thinks it
can make selling off the spectrum. But there's some strange thinking
occurring, a bit like the case just revealed of the new electric trains for
South London that can't be used as they take more current and the power
supplies aren't up to it: someone forgot about that.
I don't think the British public will take kindly to analogue being switched
off if DTT still has flaws - they won't like loosing their telly. To succeed
DTT has got to have good coverage and that will need higher transmitted
power, many more relay stations and an army of technicians to go from house
to house fitting interference suppressors to all those flourescent lights,
door bells, central heating systems, lawn mowers, motor bikes, etc, and
upgrading aerial systems. Also with a larger number of relay stations maybe
all the existing spectrum will need to be used up: after all this spectrum
has been used for TV broadcasting since the 1960s. If there is a bit of
spare spectrum when analogue goes why not use it for a few more multiplexes?

The new and small £100 Pace STB may get more interest, but a £50 STB
would do more? If they get them down to £25 it looks more reasonable
for an 'add-on' for the extra stations, to the remaining analogue
sets?

In some cases, pre-recorded stuff, there's a 'noise mask' overlayed to
disguise digital artefacts and give an impression there's more
sharpness in the picture than actually exists. Because it's a static
mask, and not random noise, it shows more during panning shots where
it's static nature is revealed. No doubt future software will fade the
mask out over passing shots.

Not quite. In many towns and cities there are entire streets and districts
that are listed. In my city, the majority of the West End consists of terraces
of sandstone buildings - and not a dish in sight !

I still think that as long as factories in Japan continue to churn out
analogue sets then analogue television broadcasting will continue
indefinitely. Some countries have no plans to ever install digital
transmitters. Infact I have a good feeling that some third world
countries still only have black and white broadcasts.
I think it would be better to make the 28 GHz region of the spectrum a special
band for licence exempt short range wireless internet access rather than try
auctioning it off. That will allow small wireless ISPs to set themselves up all
over the country without having to bid for a piece of the radio spectrum. The
only downside is that the government won't make any money out of it directly and
are reluctant to give anything away for free.
This is a good idea in principle, but there is a lot going against it,
technically.
The operating range of a 28GHz cell is no more than about 5km, so to
make proper use of the kind of bandwidth available at 28GHz, it is
necessary to sell to big businesses - domestic customers don't need
anything like that kind of bandwidth. And of course big businesses
don't want to deal with small ISPs.
Also the cost per customer of the equipment that must be deployed is
vastly higher than that used at 2.4 or 3.6GHz. This puts a crippling
lower limit on the charges that must be levied on the customer.
So to make use of this kind of bandwidth, an operator would ideally
like a national license, and the opportunity to spend the first four
or five years cherry-picking regions. One of the big reasons for the
failure of this auction was the regional nature of the licenses and
the implied coverage requirements in poor demographics.

Rubbish. Broadband internet at affordable prices to the bulk of the UK population is
simply unavailable. The present dial up system is too slow and expensive for regular
use. Private individuals do want affordable broadband at 1 Mbit/s upwards.
Ever heard of telecommuting ? It can't be done in most places because the facilities
don't exist. At the moment broadband is a postcode lottery.

Mobile phone prices came down as demand and sales increased. The same thing is sure
to happen with wireless internet if given a chance.
I will tell you that with mass produced MMICs at 28 GHz prices will not be much
higher than a system at 2.4 or 3.6 GHz.

Thats why I mentioned a licence exempt system similar to wireless LANs and working
over a slightly larger radius. Therefore tranceiver units for both subscribers and
would be wireless ISPs could be purchased off the shelf and used immediately. That
would mean that if someone wanted to set themselves up as a wireless ISP then they
could do so without having to go through the high cost and bureaucracy of spectrum
licences.
As the system will use a form of spread spectrum then if two such people set up
wireless internet servers interference between the two won't result.
Such a system will never achieve the bandwidth capacity of fibre optics or even
co-ax cable but is a perfect system for rural areas, suburbs and smaller towns.
Which in itself is a good idea. I don't think there's a one size fits
all answer to broadband so a hybrid system of cable connected in larger
towns and a radio distributed system in rural and village locations
might be a way to do this other wise there will be large parts of the
country that will be saddled with dial up for a long time to come.
I believe a company called Radiant Networks are doing something similar
to this called a mesh network where each subscriber terminal acts as a
base station that can pass packets around from location to location..
Tony Sayer
A typical cell will have a capacity of about 112Mbit/sec. The sums
don't add up for domestic consumers. I know this first hand, having
written simultaneous license applications in Denmark for 3.5 and
28GHz. The 28GHz business plan collapsed, and the 3.5GHz license was
won.
Remember you still have to pay for the Internet bandwidth - the
customer link on its own does nothing.

Sorry - I deleted a bit and didn't fill in properly. The answer is a
lot of bandwidth. The average operator will be deploying cells of four
sectors (it is virtually impossible to deploy omni antennas, and the
RA don't like it). These will have a bandwidth of 28Mbit/sec each -
112Mbit/sec per cell. There is a need for additional spectrum because
you need a different operating frequency for each adjoining sector or
cell. It is very much like mobile frequency planning.

No, these systems are strictly channelized. Some use spread spectrum

I helped write the specifications (in ETSI) for these systems as well

As I said, the bandwidth issue is not one of technology, but one of
economics. The cost of bandwidth lies in the Internet connection, not
the customer connection. The big costs associated with these systems
are the capital costs of a)installing the base station and b)
provisioning each customer.
I don't *think* that there's any country left with a B/W only system
now, but if anyone knows differently, I for one would be interested to

I would also be interested if such countries exist. Possibly small obscure

Some things don't quite work out right first time but take off later. Fax machines are
one of them. Perfected in the 1920s but rarely used until the 1980s.

Thats just speculation. They said in 1980 that mobiles will always be confined to city
executives. They said in the 1930s that television would never become mainstream and it
was radio with a picture. They said in 1990 that online information services like
Prestel were dead and that the internet would be a complete non starter. They said in
the 1950s that computers are machines of war and not machines of peacetime and of no use
to businesses whatsoever. The list goes on.

Why four ? Is there anything wrong with say 12 sectors ? In some instances less than 360
degree coverage may be desirable such as the ISP being on a coastline and not wanting to
radiate out to sea.

Having a number of sector antennas around the same tower approximates an omnidirectional

Not if CDMA or frequency hopping spread spectrum is used. One of those techniques is
what I have in mind. Not fixed frequency or TDMA.

The technology will prevent most conflicts occuring. Only when masses of users all start
downloading streamed video all at once and the allocated spectrum be completely jam

Most residential users in Britain can't afford broadband even where it exists. Prices
are substantially higher than in most parts of Europe. Its a matter of politics and

Many would disagree - I think Murdoch summed it up when he called the
licence fee an "evil tax". I for one find it difficult to tell the
difference between BBC Children's programmes and "normal" BBC
programming half the time!
Their news is biased and often inaccurate, documentaries uninnovative
and repetative, and the rest I find just too pathetic to even
criticize.
-Very- occasionally, they produce a good comedy series, but that's
all.
The "excuse" for the licence fee arrangement is supposedly that it
allows the BBC to put quality over quantity, and produce programmes
for everyone, even if some will attract only a very small number of
viewers (intellectual high brow debates etc). But where are these
programmes? The schedule is filled with simple-minded trash. And it's
relatively cheap to set up a commercial "specialist" satellite TV
station now - companies producing this niche programming are
commercially viable.
Sure, I wouldn't like to have just ITV, C4 and C5 but that's what a
satellite dish is for. And even if the licence fee were abolished, the
BBC could continue as it is - you'd have adverts, but as it is they
show loads of programme trailers anyway - equally irritating, and
dropping the licence fee would enable poorer folk to spend their
licence fee money on a subscription TV package instead, which they
otherwise wouldn't be able to afford.

Oh yes, Commercial breaks during the Proms, at regular

- I can't wait.
But I agree many BBC productions are staffed by career women
outputting mindless make-over shows.
This isn't very technical...

Do you really think there are many people who would rather watch Sky One in
preference to BBC One ?
I for one find it difficult to tell the difference between Children's
programmes and "normal" Sky programming half the time!
Talk about repetitive ! Does a whole night of "The Simpsons" really appeal to
anybody ? And "Friends" is hardly quality television.
Regarding Sky News, many beleive IT is biased and often inaccurate - how can
it be otherwise when it's financed by an individual whose only interest is in
making money out of it.
I wouldn't take my morality guidance on what is good and evil from Mr
Murdoch... I suspect he is just very annoyed that Britain has such a strong
public service broadcasting establishment, and he is annoyed that he has
never been able to establish himself within it, apart from as a pay TV
provider. (He tried to buy LWT in the 70s didn't he? Never really forgiven
the establishment for not being allowed to)
>I for one find it difficult to tell the
>difference between BBC Children's programmes and "normal" BBC
>programming half the time!
Do you watch BBC kids and adult shows? (I agree BBC kids shows have some of
the best production values around though - some of their drama is absolutely
top knotch...)
>Their news is biased and often inaccurate, documentaries uninnovative

Interesting you find BBC News biased and inaccurate - what do you base this
on?
The BBC World service seems to be the most trusted radio broadcaster
globally, as does BBC World TV, which is closely linked with News 24. Can
you suggest a global broadcaster whose newsgathering you would trust more?
The decimated ITN is hardly providing much competition these days - far more
of its reports coming from edit suites in Central London than yesteryear...
I do get extremely annoyed by throwaway comments like this. Would you
rather have your TV and Radio News provided by the same news organisation
that publishes The Sun, The Sunday Times and The News of the World?
Great... Truly unbiased...

What is wrong with making programmes that only some of the population want
to watch? Should all programmes appeal to everyone? Surely the fact that a
range of programmes - highbrow and populist - is available to the whole
nation is an argument to retain the licence fee? Much more egalitarian than
the subscription alternative IMHO.

Yep - but only on a subscription model - and very few are making a profit.
Very few are actually making their own programmes of a decent quality - most
are just buying in stuff of dubious quality, or age...

Advertising revenue is finite - therefore Sky, ITV, C4 and C5 would have
reduced incomes. (ITV would no doubt just halve ITNs funding again... C5
would just axe more news programmes, and show Sky News instead...)
You may find trailers as irritating as adverts - I can guarantee you many
parents would not agree. They'd be very happy to allow their kids to watch
childrens TV, with trailers but minus the adverts for expensive toys, fast
food etc. Why do you think the ratings for CBBC on Choice are so high in
multi-channel households?!
Would you fund BBC Radio in the same way, without a licence fee? Radios 3,
4 and 5 with adverts - great for long music concerts and editorial
integrity. Say goodbye to any consumer journalism... (Oh yes - the
advertising funded ILR radio services, ITV, C4, C5 and Sky are crawling with
programmes critical of companies that advertise on their channels - silly
me, I must always miss them...) BBC Local Radio, providing genuinely useful
community services through their carelines... Do you think this would
continue under a commercial management?
As for not paying a TV licence allowing people on a low income to afford Pay
TV. The "Full basic" - i.e. non films, non sport - Sky Family package is
£16 per month... Annually almost twice the licence fee...
Sorry - can't agree with your argument - probably pointless to try to reply
to it - but I feel very strongly that the BBC is worth defending.
FYI : I do subscribe to Sky (Family pack) strangely I spend most of my time
watching the Beeb channels... God knows how many channels but very little
worth watching.

The point I am making here is that with a total cell bandwidth of
112Mbit/sec, if you want to actually justify that bandwidth and make
use of it, each domestic user will have a huge access speed. If that
is to be reflected in a matching speed on the Internet. That
connection has to be paid for, and must be passed on to the customer.
Very few domestic customers will be happy to meet that kind of cost.

Absolutely. But it must be an appropriate connection. 112Mbit/sec
shared between perhaps 100 connected users in a cell is not an
appropriate connection for domestic customers. It may be for some
businesses.

Sure it is speculation. But it has a basis. As I have said already, it
is not an appropriate connection for a domestic user, so there is no
reason for the volumes to increase. We have all heard the hype over
streaming content, but like video conferencing it keeps getting
promised but not happening. If serious video content is ever really
needed, then the 40GHz MDS band is waiting, with much more bandwidth
suited to broadcast distribution. 28GHz is sitting in a no-mans land.

Four sector antennas are type-approved. If you want less, sure you
miss some sectors - as you say on a coastline. But as for more sectors
- at 28Mbit/sec per sector you would need an incredibly
densely-populated and demanding consumer set for that kind of
requirement.

Absolutely, but again I am considering the bandwidth situation.
28Mbit/sec shared over the whole 360 degrees would make a lot more
commercial sense, but it can't be done. If you want four sectors, they
must be on separate frequencies or you get interference fringes where
there is no signal.

Not so. CDMA relies on signal level control to manage the near-far
effect. Signal levels can only be managed on the wanted link. To any
other receiver they are simply interference. If two operators want to
share one area, they must be given different channels. You would not
believe the hours a bunch of us spent in the New Technologies group of
CEPT (SE19) designing and testing interference scenarios to come up
with geographic and frequency planning rules acceptable to all
manufacturers and regulators.

Absolutely right. And deploying equipment with inherent performance at

sense.

No it isn't. A television aerial costs about £2, and the installation
perhaps £50. At 28GHz the capital cost of an installation is about
£800 for the equipment and another £200 for the installation. That is
in no way equivalent.

There is no reason for such a high bandwidth. I mentioned an operating frequency centred
around 28 GHz but did not specify the cell bandwidth or connection bandwidth. A connection
bandwidth of 1-2Mbit/s would be more than enough for most residential users at present.

By having more sectors reduces the overall areas that would be in nulls if a four sector

You only need one protocol that can be used by many different equipment manufacturers.

The Radiocommunications Agency is a secretive elitist institution that doesn't like
listening to the general public even if they have degrees in electronic engineering and
design RF and microwave hardware as a career. Many times I have submitted concepts and
proposals to the Radiocommunications Agency or the DTI but I got no replies and no action
seemed to be taken. I have also contacted my MP about the concept and the possibility of
bringing up some form of debate in parliament or passing on the info to the appropriate
technical authorities but again nothing seems to have materialised.

The antenna will probably be the most expensive part but mass produced the prices will fall
to become affordable. Like satellite dishes in a way.

This band is a done deal. It has been before WRC. The channel widths
are defined, and the associated bandwidths go along with those channel
widths. You can't deploy 1-2Mbits/sec at 28GHz. You can at 3.6GHz.

Capital costs have nothing to do with bandwidth, just variable costs.

No it can't. CDMA is entirely DSP and does the best it can. There is
nothing that additional DSP will do to remove interference from a CDMA
signal.

Not at all. This isn't a mobile band and there is no need to
accommodate other manufacturers' equipment that might wander into the
service area. All you need is protocols that are compatible at the
co-existence level.

You don't understand the RA. It is neither secretive nor elitist. Also
it does not instigate any standards at anybody's individual behest.
The position the RA took to WRC was that agreed as a Europe-wide
decision. That decision was made by me and many other people
representing industry and regulators from all over the place. The
meetings were open forums - anybody could be nominated for inclusion.
Preparatory to each meeting was a UK meeting hosted by either the RA
or a British company, in which a consensus view was obtained and put
forward as the UK position by the RA, on behalf of everybody. That
position was supported by reams of technical papers provided by me and
others which would be discussed and modified in great detail by the
European body.
That is how it works, and the idea that you can simply phone or write
to the RA and either demand or suggest that they do this or that is
naive beyond belief. Everything the RA does is with the express
instruction of the UK telecoms industry - whether manufacturing or
operating.

Again, you are too late. If you had a brilliant concept, you should
have taken it to a manufacturer or operator willing to spend the time
and money placing it before the appropriate European bodies. Even
then, as a solitary position, at variance with everybody else's vision
for the band you would have made no progress.

No. Not like satellite dishes. This isn't just an antenna. This is a
highly regulated, licensed two-way link. It must be type-approved and
is subject to instant removal if it causes interference.
It comprises an antenna, transceiver unit and distribution box. It
must be installed by an accredited installer who can guarantee
line-of-sight and sign on the dotted line that he has done it
properly.

I had my concept in mind since 1996 and contacted various RF system manufacturers about it.
Their responses varied: Some failed to reply, others claimed the system would never take off
due to lack of demand, others told me that the technology exists but the political will to make
a portion of the spectrum available is what is stopping it from becoming reality, others said
they also had the idea and would start making equipment once the frequency band was allocated,
others failed to take the matter seriously, others claimed it would be a too much of a threat
to existing technology, others said the system would take off in other countries but not
Britain because of the publics opposition to phone masts being extended to wireless internet.
The list goes on.
> Even
> then, as a solitary position, at variance with everybody else's vision

It is the concept I am talking about and not a use for 28 GHz. The transmitter frequency is
somewhat immaterial as long as the system works.
Erm.... that isn't exactly saying much, I think your point is a little
self-defeating you mean to say BBC1 mind numbing junk outperforms ITV's mind
numbing junk? Wow... they must be proud.
The problem is, the BBC has become lazy and therefore producing formulaic
uninnovative shows en masse all set within the same genre, now that's fine
for day time stuff but its unashamedly spilled over into the rest of the
schedule, the quantity of East Enders is an example of that, a greatdeal of
people simply don't care for it every night of the week, and I've never
heard 'everyone talking about it', in a dash for rating they've out trashed
the commercial channels.
At least ITV has the excuse of declining advertising revenues to justify
sloppy shows, with the BBC it's just the opposite. If the shows and scripts
are trash then it doesn't matter how much money you have or how good the
quality of production is, you still end up with trash. Hence 'tripping over
your own wallet'.
Whenever there's a whiff of criticism then self-congratulation doesn't help
either, the BBC can't live on its reputation if they're constantly
undermining the values that established that reputation. It would be a sad
day if the BBC went commercial, but the way the programming is purely
focused on ratings it seems they're setting themselves up for that trap,
they may well end up being their own worst enemy.
If the BBC carry on this course people will perceive it to be of little or
no value, or no better than several junky channels already available through
Sky/Cable for free. The licence fee is an entirely unenforceable system that
solely relies on good will, once you loose the faith of the public it all
comes crumbling down, I hope it doesn't happen.

Comparison to the many other news broasdcasters available via
satellite (not just those on "Sky".) It's pro-labour (and that's a
widely-held view), pro-Muslim and *very* liberal. They don't even
report certain events atall sometimes, if such events put liberalism,
labour and/or Muslims in a bad light.

I honestly don't think that the parent organisations tend to affect

Dot.TV was a good example of a channel that *did* make its own
programmes. In this case they provided often-detailed information for
home computer enthusiasts. CPD Dental TV is another example. But I
suspect most of the people who would've watched these channels are too
bigoted to get a satellite dish.
I find alot of the other channels' programming to be of high quality.
The fact that it's been bought-in from, say, Australia or the US
doesn't bother me.

I disagree, because a specialist channel would be able to attract
advertisers selling specialist products and services aimed at an
audience which they would only find watching that channel, and which
wouldn't have advertised on TV atall otherwise.

Editorial integrity? You mean like that of, for example, Jeremy
Clarkson, who appears on the BBC and is "sponsored" by Ford?
And to take the example of Radios 1 and 2 - there are dozens of
musical "scenes"/genres which they don't cover, but many of these are
covered by commercial satellite radio broadcasters. Same goes for
music on BBC TV.

"Community services" - it's all the same trash. Like "are you feeling

goes round in annual circles. In November, you always get "Remember
not to light a firework if it's only 2 inches from your face!". Need I
go on?

Really. I think CBBC was a darn sight better in the 80s. They had really great
cartoons and more educational programmes back then. Much of the drama IMO is
crude and uninspiring like Byker Grove and Microsoap. I actually feel sorry for
kids nowadays.

I think that different news broadcasters should concentrate on different types
of news. Some for foreign, some for local, some for specialist issues like the
environment or medical discoveries. One thing I have noticed about television
news is that most is bad news or of a problem variety. Perhaps we should have
some channels focussing on good news for a change.
I was thinking of breaking up the BBC and having one or more channels on
subscription for the populist and entertainment stuff and having another funded
directly from the treasury for as a public information channel showing things
like news, weather reports, political coverage and certain documentries like
Horizon and Panorama along with their teletext service.
Not exactly mass market stuff and no need for any viewing ratings but cheap
enough to do away with the licence.

They could be funded directly from the public purse and considered as a public
service with the government assuming everyone has a radio receiver of some
sort. The amount of money required to maintain the system and its quality will
only be a miniscule fraction of the total taxation revenue anyway. I did hear
that if a radio licence still existed its annual cost would only be in the
£1.50 region.

I've yet to see the same piece performed twice during the Proms,
televised or otherwise, with the exception of the second half of the
Last Night. But then, last year's Last Night didn't contain the
traditional pieces.

Sky One is admittedly very poor now (some would argue it's always been that
way, but they used to show more quirky US programming in the beginning, ie
Picket Fences) - But if I were forced to choose between BBC 1 and Sky One I
know which one I'd pick, Sky One. They've got Simpsons, Futurama, X-Files -
well that's it, but the only good thing about BBC 1 is News24 through the
night! (Nice and handy if you're staying at a friends without digital TV and
you can't sleep)

I could be locked in a cell with a TV showing nothing but The Simpsons and
I'd never get bored! Well as long as they weren't showing season one ad
nauseum.

Sky News has become very tacky looking of late but it's still a good news
channel IMHO and far from biased - No more so than any other TV news outlet.
As for a certain individual making money out of it, I believe the channel
has never turned a profit and is unlikely to do so in the near future.
Basically it's a "loss-leader".

But nearly the same as the cost of the BBC to the average licence paying
taxpayer. ( £109 + WSR + over-75s subsidy + approx 9% of running costs of
Magistrates Courts + debt counselling + imprisonment costs + costs to
consumers
of goods/services advertised on the beeb + wages of certain people at DCMS )

Better stop this - you know it isn't technical.

Most are not old classics but stuff which is out of the ark and not all
that good even when released. They are just space filling as they have
nothing better to show.

Sounds like you want a restaurant that chooses its meals for the
customer.
I think that television channels should specialise rather than be jack
of all trades.
Don't the digital cable companies just take the DTT off air and remultiplex
it?
Probably. Its like lots of cable TV providers worldwide take satellite
broadcasts and remultiplex them.
