You must live in my neighborhood! :)

You bring up two important issues:
a. Power at the remote site 800 feet away, and,
b. The Fresnel zone of a pole only six feet tall

You can look up the Fresnel zone stuff separately, which, in my experience,
is more theoretical than practical since you just shove more directional
beam power to overcome the losses due to lack of height.

Power is an issue.

I'll ping "alt.internet.wireless" & "sci.electronics.repair" with this
post, who may be able to assist you more so than I can in how to set up the
power (be advised to ignore the three infants on s.e.r if they respond).

What we do here in the Santa Cruz mountains, where the zoning is 40 acres
per household, is "bucket routers" which are simply routers plugged into
anything we can plug them into, between homes when we need to clear
obstructions to our Line of Sight (LOS) WiFi transceivers.

But your suggestion of solar seems far better than bucket routers.

Oh, be nice. 300ft is about the limit for omnidirectional antennas on
both ends of a 2.4GHz link. For 800ft, directional antennas with some
gain are going to be required. To get some decent speeds, 5GHz
instead of 2.4GHz.

Small antennas, long range, high speed... pick any two.

I tried linking the shop to the house on 2.4 using 24" antennas
at both ends. Distance was 1400 feet.
Never could get it to work.

I bought a pair of Ubiquiti LiteBeam M5 with 23 dB antennas.
Absolutely solid link.

I've seen that before. I don't have a Model 15. I have a Lorenz

Hi Jeff,

We go way back, decades, regarding Fox's/Snit's childish rants on Usenet...
o Nobody takes Snit/Fox seriously (just google for his name for reference).

Don't worry about Snit (Michael Glasser is who Fox's Mercantile really is).
o He admitted it himself, years ago, when we caught him with the same IP

What I want to say is that I THANK YOU for helping the OP out.
o I know there are adults on s.e.r who, like you, are knowledgeable.

The whole point of adding s.e.r and a.i.w was that the Windows group needed
your expert assistance, which I, as an adult, for one, greatly appreciate.

Let's hope the OP reads your advice and takes it to heart for his problem
o Adults like you can help him, and, in doing so, you help all of us.

It's what Usenet is supposed to be all about...
o To that end, I include the OP's original post, verbatim, below:

I didn't want to hijack the other thread but Arlen got my interest
with those antennas.

If I wanted to hit a LAN based camera 800' away, what would I need to
to do (clear LOS).

The objective would be to attach it to an existing security DVR that
has 2 unused WiFi portals.

I am trying to avoid the cloud/phone thing but that seems to be what
most of these ones I see are doing these days. I assume once they are
on the network I could coax my DVR to see them.

Do I need an enhanced antenna at both ends or would the dish at the
host end give me enough signal strength to talk?

Thanks

The other Jeff and I go back before that to when we both lived in the

Wrong. I'm not sure if Jeff wants me to reveal his real name, so I'll

12 KILOMETER (7.5 miles) Wi-Fi:
<https://www.youtube.com/watch?v=lYJFwXw1ZIc>
Notice that they're using 5GHz, no bore sight alignment, no bubble
level to set the mounting poles vertical, no binoculars, no map table,
etc. Fortunately, none of this will be needed at 800 feet on 2.4 GHz.

>It's what Usenet is supposed to be all about...

Based on quantity, I thought that Usenet was the for distributing
porno, copyright violations, pirated software, fake news, bad jokes,
character assassinations, ego inflation, reputation aggrandizement,
and spam. If there is any useful information involved in Usenet, it's
a very tiny amount.


Marginally related drivel (for my ego and your amusement):
<http://www.learnbydestroying.com/jeffl/ADS-B/FR24/NooElec-SDR-indoor-monopole.jpg>
ADS-B receiver using Raspberry Pi 3, Virtual Radar Server, and
problematic Flight Radar FR24 software. Antenna is a paper clip
plugged into a NooElec Nano 1 SDR sitting on my desk. The colorful
display is the coverage area from my receiver. Different colors are
different altitude ranges. Notice the big peak at 45deg towards Lake
Tahoe and the big "holes" either side of the peak. After fiddling
with the antenna for several hours, I look out the window and notice a
small grove of redwood trees in the "holes" and an open area at 45
deg. Lesson learned: 1GHz RF doesn't go through big tree trunks.

Hi Jeff Liebermann,

These worthless pieces of shit like Fox's Mercantile are who ruin Usenet.
o Not people like you and me who are purposefully helpful & who add value.

You know me since we've communicated in email, where you know I don't
bullshit and that I'm always purposefully helpful in intent & detail.

As are you, where you've helped me a lot with the local WISP over the
years, where you know that what I say is always intended to be helfpul.

By way of stark contrast, this proven worthless piece of shit that goes by
the nym Fox's Mercantile is the opposite of both you and me.

If this worthless piece of shit Fox's Mercantile is not Snit, then he acts
EXACTLY like Snit does - which is essentially the same thing in effect.

If it wasn't so sad that Fox's Mercantile proves my point in every post, I
could take solace in the fact he _always_ proves to be a worthless pieces
of shit.
a. unhelpful to the core in every post
b. infantile to the max in his every word
c. lacking in even the most basic of adult cognitive skills

Notice _every_ post from Snit (Fox's Mercantile) is an infantile post
of the kind we'd expect from worthless pieces of shit like he proves to be.

Which is pretty funny since this worthless piece of shit who uses the nym
"Fox's Mercantile", among others, just proved, in front of all of us that
he lacks the adult cognitive skills to even attribute a quote correctly.

Years back, I believe in the long defunct Byte magazine, I read an article about someone who typed 8 bit ASCII while riding a bike, using 4 microswitches on each handlebar grip. I think that would one-up the Teletype terminal.

I have tried to find the article without success. The claim was that he wrote his monthly column while on vacation bicycling.

Hi Jeff,

Jeff - please do not respond to this post unless you _understand_
1. I never respond to Fox's Mercantile unless/until he attacks me
(Bear in mind he _always_ attacks me!)
2. I'm only proving what Fox's Mercantile is - by pointing to what he does
(Bear in mind what he does proves he's an infantile piece of shit)

You're intelligent - you're a helpful person - so you need to know.
o It's not in the least the ping-pong what you just said it was.

This is not an even match of wits - for sure - given Fox's Mercantile is a
worthless piece of shit common troll of absolutely zero value whatsoever.

I repeat that this is not a ping-pong in the least...

For _two_ very good reasons
1. I ignore Fox's Mercantile in _every_ thread where he doesn't attack me
2. Everything I say about Fox's Mercantile is an easily verified fact

You can verify that fact yourself, Jeff - if you realize those two things
o Bear in mind I don't feed the trolls - except & only when they attack me.

If Fox's Mercantile didn't attack me - you wouldn't see _any_ of this.
o Because I ignore Fox's Mercantile simply because he _is_ a piece of shit.

I care that you _understand_ what I'm doing, Jeff...
o Since we are both compatriots in being purposefully helpful people.

And I care that you comprehend that I'm extremely well educated Jeff
o What I'm doing is what we're taught to do when cowardly bullies attack.

Fox's Mercantile is a cowardly bully who pays no penalty for his posts.
o He trolls my threads _every_ single time I post anything of value.

Given Fox's Mercantile is nothing but a worthless piece of shit troll..

I _never_ (ever!) never ever (never!) respond to Fox's Mercantile
... unless....
o Unless Fox's Mercantile plays his infantile games as he did here.

All I am doing, Jeff, is _proving_ that Fox's Mercantile is clearly
a. The aggressor here (I repeat: I _never_ respond to him otherwise!)
b. A worthless piece of common troll shit with an infantile brain.

Jeff - please do not respond to this post unless you _understand_
1. I never respond to Fox's Mercantile unless he attacks me

I'm always amused at the sheer amount of time and effort some posters
put into these useless exchanges - not just the "calling" ones, but
people who ask questions then quibble about what they consider wrong
advice - they must waste hours on it. Wish I had the stamina - I'd put
it to better use.

Jim Jackson,

I only need to point to exactly what Fox's Mercantile writes...
o In order to prove the veracity of my claims about him.

I'm extremely well educated where I've been taught how to handle bullies.
o My approach is a basic factual defense which you would also likely do.

FACT:
Q: Do I _ever_ respond to Fox's Mercantile ever in any thread
where Fox's Mercantile hasn't unilaterally attacked me?
There is only a single one-word answered asked of you, Jim Jackson:
o (yes or no, please)

ASSESSMENT asked of you:
What do _you_ make of these initial responses by Fox's Mercantile
o Compared to this initial post by me asking for help from this newsgroup?

Note two very important facts _before_ you respond because if/when you
respond, as I will certainly _ask_ you if you understood these two facts.
1. I never respond in any thread to Fox's Mercantile's trolling...
2. Unless, and until, he attacks me, out of the blue, as he always does

When I respond to Fox's Mercantile, it's to continue to prove...
a. Fox's Mercantile is a common cowardly bully who always bullies me
b. As such, Fox's Mercantile is a worthless piece of shit common troll

Bear in mind... If you respond, I will ask you to stay on _that_ topic.
o Because it's these pieces of shit like Fox's Mercantile who ruin Usenet.
--
Since I care about my credibility, I need you to recognize two key facts:

1. I never respond to Fox's Mercantile unless/until he attacks me

2. I'm only proving what Fox's Mercantile is - by pointing to what he does

Fox's Mercantile is a cowardly bullying worthless piece of shit common
troll where the recent thread proves that well-known fact in spades.

Hi Jim Jackson,

Pernicious trolls like Fox's Mercantile are those who ruin Usenet for all.
o Hence it's important that _all_ of us discourage their despicable actions

Thank you for being an adult above - so we didn't waste time on obvious facts.
o As you observed, it's trivial to prove what Fox's Mercantile always does
(as he did in this very thread - & always does - because he's a troll)

Literally every time I post, I have Fox's Mercantile infantile responses to
deal with, but what's worse is he attempts to troll derail _every_ thread.

Others... more so than just me... need to help put a stop to this
o Otherwise this newsgroup, like many others, is handed to these trolls.

All Fox's Mercantile did in response to the request for help - was troll.

It's what worthless pieces of shit trolls do, as you & I are aware...
o But, like Snit, this Fox's Mercantile is particularly pernicious about it

In summary, while yours is a great question, you're asking it of the wrong
person, since you should be asking Fox's Mercantile why he does what he
does.

I would be happy if this infantile troll would just stop sniffing my ass
o I repeat: If Fox's Mercantile ignores me - I'm happy to ignore him.

He's a worthless piece of shit troll anyway...
o So he can't possibly ever add any adult value to any thread topic.

The problem is that if I don't make it obvious to all here what he does...
o These cowardly infantile bullies will never stop ruining this newsgroup.

Chuckle. Allegedly, computahs are labor and time saving devices. It
would seem that we are experiencing a demonstration proving quite the
opposite. I've been submerged in Usenet for far to long to recall
what I did for entertainment prior to about 1981. I suspect it was
something equally useless and likely laced with debauchery.

Someone wiser than me once noted that Usenet conversations were really
not for the benefit of the participants. Instead, they merely
establish a mostly permanent record of the participants point of view,
so that some other future Usenet conversationalists can use them as
references. The lack of a clear winner in all Usenet conversations is
clearly proof that winning the discussion is not a priority. Many of
the successors to Usenet actually award points or badges for being the
most cited. The only good part is that where there are no clear
winners, there are also no clear losers. Let the most mediocre
position win.

This probably won't improve your understanding or stamina, but might
prove amusing. I wrote it when I was thinking along lines similar to
your lament:
<http://www.learnbydestroying.com/jeffl/crud/genesis.txt>

And the lord looked upon the Usenet wasteland and proclaimed
"I have given unto thee a temple upon which thou may rant.
Instead, though hath turned my temple into a den of iniquity
and dung hole of misinformation. Unto thy ancestors, I
gave 10 commandments, but unto thee I shall give but one;
Thou shalt not post what thou also find unworthy of reading."

Hmmm... I probably shouldn't have posted this message.

Hi Allodoxaphobia,

I certainly comprehend your intent, and, as an adult, I will comply.
o I will not further respond to the Fox's Mercantile troll in this thread.

I've already proven my point of what Fox's Mercantile incessantly does.
o Which is, after all, directly & clearly where the condemnation lies.

And, as Jim Jackson agreed to a while ago...
o That proof is, by now, obvious to all those with adult cognitive skills

As such, I will end this direct proof of what Fox's Mercantile is...
o Which is he's nothing more than a worthless pieces of shit, ala Snit.

As we all know the Internet adage about 'dropping to their level'...
o I understand that you lump me into the same category (erroneously so).

That's fine - as you might not fully comprehend my intent.

That is an absolutely correct assessment.

You can advise the OP better than I on potential Fresnel Zone issues, as
he's apparently asking how best to paint a LOS location 800 feet away with
the transceiver on a pole I believe.

You can run the math to explain to him how high that pole may need to be.
(We do that stuff by trial and error - but you may know the math better.)

Please advise the OP on the math so he knows how high to mount the radio.

While there are 2.4GHz routers available that have a 40MHz channel
bandwidth setting, I prefer not to use it because it reduces the
available bandwidth to other users on 2.4GHz. If one is sufficiently
clueless to use a 40 MHz channel set to CH6, it will effectively
trash most of the 2.4GHz band. Since Wi-Fi pollution can be
symmetrical, it also makes the receiver susceptible to more
interference. Stay with 20MHz channel bandwidth on 2.4GHz.

On the other foot, the minimum channel bandwidth on 5GHz is 40MHz
(depending on channel selected) with an option to use 80MHz or 160MHz
for 802.11AC and AX (Wi-Fi 6).
<https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_or_5.9_GHz_(802.11a/h/j/n/ac/ax)>
With 1024-QAM, 802.11AX can theoretically do 1.2Gbits/sec in a 160MHz
channel. Your mileage will certainly be less.

The test below was to demonstrate something else. However, it does
show what can be done with 5GHz.
<http://www.learnbydestroying.com/jeffl/FLUG-talk-2015-02-28/802.1a%20direct.jpg>
Unfortunately, the radios at both ends were only 802.11a, so the speed
never went above 75 Mbits/sec at a distance of about 5 meters. It
also uses Jperf 2.0.2, which doesn't work very well above 100
Mbit/sec. I should have used Iperf 3, which works well into the
gigabit range:
<https://iperf.fr/iperf-download.php>
My home network is now mostly gigabit, so I could easily run some 5GHz
performance tests with a later version of Iperf 3. However, no pretty
graphs as nobody has bothered to port the Java code to work with
Iperf3. I'm a horrible programmist, so I won't attempt it.

Anyway, the performance limiting factor is usually interference from
co-channel users and noise sources. You could have all the bandwidth
in the world, the most efficient modulation scheme, maximum legal RF
power, and still not be able to communicate very well or far if there
is an interference source nearby. In other words, one needs to do
more than just "widen the channel".

Sigh. I've lost count how many times I've done that in this
newsgroup. Start here:
<https://www.proxim.com/en/products/knowledge-center/calculations/calculations-fresnel-clearance-zone>
800 ft is not far enough apart to worry about the curvature of the
earth.
800ft / 5280ft/mile = 0.152 miles
At 2.4Ghz, the Fresnel Zone is 9 ft radius at the midpoint of the
link. Therefore, the antenna at both ends of the link need to be at
least 9 ft off the ground, or 9 ft above any major obstructions
(fences, trees, buildings, cars, etc). Actually, it's somewhat more
complicated if I throw in fade margin, frequency selective fading, and
system availability, but we won't need to go there for this example.

At 5 GHz, the Fresnel Zone radius is only 6.3 ft. Therefore, the
antenna pole can be 2.7 feet shorter.

Congratulations. You'll now enjoyably find everything you knew

any of those filling your shoes here and I usually only bother to lurk

I've run cantenna line-of-site over 400m reliably for years. I didn't
measure the fresnel zone but a farmer's apple tree in his front must
have encroached the signal line every few years and he would kindly
lop a few branches, restoring normal service. I have a note of the
speeds somewhere but the system gave me office access from home, home
broadband via the office and all I remember is that the Wi-Fi speed
was better than the rather poor broadband speed available at the end
of a long exchange line.

After moving several years ago from the little hamlet (60 properties)
the pathetic broadband (I think I had one of the best connections at
2mbps) was replaced by FTTP. I don't think I could have got mi Wi-Fi
signal to keep up with the resulting 80Mbps broadband. Those we now
Zoom with in that hamlet are always very clear and no blurring motion
issues - I'm somewhat jealous.

Thanks. However, it's not easy to find enjoyment while trying to
adjust to Covid-19, dysfunctional government at all levels, impending
economic collapse, limits on travel, increasing weather related
problems, an increasing homeless problem, and probably increased taxes
to keep the economy afloat. Health problems and advancing age
increasingly limit my activities. I can survive on Social Security
payments and the 80% that Medicare provides, but suspect those
benefits to will eventually be reduced by inflation as the government
resorts to printing money to finance its activities. I expect my
"retirement" to more closely resemble living on unemployment with the
added bonus of having no debt and a modest bank account. Since I have
no children or immediate family, I could easily have obtained a
reverse mortgage on my house, and lived off the cash. However, the
recent fires in California might make that impossible due to
increasing difficulties obtaining replacement value fire insurance, a
basic requirement for a reverse mortgage. In other words, the long
term prospects for an enjoyable retirement look rather grim.

However, before I blunder on into this dismal future, I have an
immediate problem to deal with. I brought about 75% of the contents
of my formerly palatial office to my house when I moved out. There
was no time to do sorting, only time to box everything and move. I
moved it in small increments because I have no garage or storage space
at the house and because I had to carry the boxes up about 50 stairs.
The boxes are now piled up both inside and outside the house. Much of
it is covered with ash that is still falling from the trees due to the
recent nearby fires. Rain will likely arrive in a few weeks and
nothing outside is protected. I need to deal with that immediately,
but can't during the current heat waves. At least I won't be bored
looking for something to do.

Incidentally, it's now 6AM and 75F (24C) outside. NWS predicts the
temperature to rise to 101F (38C) today. I might be able to do 2-3
hrs of box shuffling today. It's likely that the local power company,
PG&E, will intentionally disconnect the power to prevent falling power
lines from starting more fires and to reduce the load on the power
grid from air conditioning.

Thanks again for the hopeful thoughts, but this is not the retirement
that I had planned and is unlikely to be enjoyable.

[peterw...@gmail.com]

Given the price of real-estate, and the cost-of-living in Santa Cruz, given that you are apparently single, given that you are apparently not overly happy about the climate, have you ever considered relocating to a more amenable part of the country? When we moved 12 years ago (just across the township), it was akin to shedding a skin. The divestiture of unneeded *stuff* was pretty immense and very cleansing. We have been vary careful not to re-acquire since. It really does make a difference. But, a more distant move in your case may solve a number of financial, physical and logistic issues all at once.

Best of luck with it. My wife is retired, my identified date is June 30, 2022 when my major tenant ends its lease. Until then, my wife and I are busy 'feathering our nests" so that when we retired and our income drops by six figures we will have few expenses and no debt on what amounts to be two very nearly maintenance-free houses.

Take care!

Actually, I have done some online looking at some possible places to
relocate. The exodus from California seems to be mostly to the
northern and eastern states:
<https://www.mercurynews.com/2019/11/04/691145-californians-left-last-year-what-state-did-they-go-to/>
Texas seems to be the largest, with a predictable reaction:
"Why Texans Don’t Want Any More Californians"
<https://www.theatlantic.com/ideas/archive/2020/01/the-truth-about-the-california-exodus/605833/>
There are also a fair number of YouTube videos on "Why you don't want
to move to [insert name of state]".

After I work out the migration pattern, the next step would be to
decide if I want to move to where everyone is going, or if I want to
avoid those places. Right now, I don't know. I originally moved to
Santa Cruz from the Smog Angeles area in about 1973 because it was
less crowded. I wanted to get away from the crowds. Before Covid-19
drastically cut down on the traffic earlier this year, Santa Cruz
traffic had become as bad as Smog Angeles over the past 47 years. If
I move, I don't want to become part of that problem. However, the
main reasons I haven't moved somewhere else is that I don't have any
urgent need to move, and that my house has some problems that will
either be too expensive or difficult to fix economically. It's a can
of worms I don't want to open at this time. There's also the problem
of my lack of longevity. If my family history is an indication of how
long I'll live, I probably won't live long enough to enjoy the change
of location.

I know the feeling. Several of my friends have become minimalists.
Unfortunately, I've been the recipient of some of their accumulated
junk. I would say they were most successful in what they were trying
to accomplish. For me, it's quite different. While I'm not quite a
packrat, I do tend to accumulate "stuff". Since I don't have a family
and have yet to immerse myself in public service and volunteer
organizations, I tend to replace these with gadgets, things, gizmos,
and goodies. I fix things, I enjoy the work, and would happily spend
the rest of my continuing to save "stuff" from a premature demise in a
landfill. I guess I'm an eco-freak of sorts. Moving wouldn't change
much.

Nicely done. Sounds like you have things well planned and organized.
I thought my plans were similarly set. Then, I had to deal with some
nasty medical problems, a pandemic, wildfires, and an evacuation. The
assumptions I made in planning my retirement have not gone up in smoke
yet, but are likely to do so considering the circumstances I itemized
in a previous rant. May your ration of luck survive and hopefully,
you won't need to deal with my problems.

Thanks. Time for a fast dinner and off to a friend to fix a Brother
sewing machine and a Baby Lock. As long as there are things that I
can fix and that need fixing, I should be ok.

I dunno. It appears to me that some residents are resorting to making
YouTube video to discourage immigrants. I can almost visualize being
greeted by a lynch mob. So much for safety.

Incidentally, I haven't been to a restaurant since late February 2020.
I really miss them. I used to hang out at the local coffee shops
meeting others with like interests. Zoom meetings are a poor
substitute. On the other hand, my food, entertainment, and gasoline
budgets have been dramatically reduced, I've lost some weight, I'm
sloooooowly learning how to cook, and I've forgotten how to calculate
a tip. Eventually, the pandemic will end, and I'll probably return to
my former decadent and lavish lifestyle. Until then, I think I can
survive without restaurants, fast food, and coffee shops.

More seriously, I've looked into selling my house and buying something
cheaper elsewhere. I'd rather not go into detail, but it's not going
to work for me. If I discount my house and convince a buyer to buy
the house as-is (after a full disclosure), the difference between the
discounted selling price and the purchase price of a replacement
house, will be rapidly consumed by the sales commissions, moving
expenses, repairs, deposits, etc. At best, it would be break even.

Also, I don't like cities. I grew up in Smog Angeles, which is an
example of a city to avoid. If I do eventually move elsewhere, it
will probably be to a small rural town similar to where I'm now
living.

If I want better entertainment, shopping, medical facilities, and
restaurants offered by the big city, I'll just drive there. I don't
need to live there.

That's a very good yield from older PCB edge connectors, which were
plated with 50 microns gold plating. These days, the commercial stuff
is more like 5 microns. (1 micron = 1痠 = 1 millionth of a meter).
Therefore, the yield is much less. I have a small forge that I use
mostly for aluminum and brass casting, but has been used to melt gold.
Also, part of my house once looked like a chemistry lab, but that's
long gone.

Nice video. He points out and demonstrates some of the common
problems with gold recovery. In terms of gross profit and time burn,
I've found it best to just sell the scrap gold and let someone else
deal with the chemicals and gold brokers.

I just emptied my safe deposit box so here is a photo of some gold
extraction that I did about 40 years ago.
<http://www.11junk.com/jeffl/pics/drivel/index.html#Gold-01.jpg>
At about $1,900/oz (spot price), they should be worth $2,470. However,
it's not so simple. The two blobs are not pure 24K gold. I don't
recall exactly, but I think they're only about 90%. I need to refine
them to at least 99% before I can sell them as 24K. Then, I have to
have them assayed by a certified lab for about $135. I don't know how
much dealer will take, but I'm sure it's too much.
<https://santacruzgold.biz>

However, I may have done something dumb. I couldn't find anyone to
buy my collection of old PCB's (printed circuit boards). It was quite
a pile that filled the back of my Subaru. I failed to find anyone who
wanted to buy it all. 1.5 months of office rent was about equal to
what I might obtain from the sale or from gold extraction. So, I
donated the entire mess to a local charity run recycler:
<https://www.greybears.org/our-programs/recycle/electronics-recycling/>
I would have dragged everything home and stored it until I had time to
do another gold extraction, but there was no time and no storage
space.

>I suspect getting chemistry glass and HCL delivered to the Santa

Not a problem. I've had a chemistry lab of sorts in my house for
years without incident. Over the years, we've also had various meth
labs and recreational chemical factories operating nearby. The
glassware and chemicals are not much of a problem. Disposing of the
waste and cleaning up the mess after the chemists move out, are very
real problems.

I prefer not to explain, but if I can contrive a believable and
documented reason for purchasing chemicals, it's not a problem.

>Food for thought...

Thanks, but I don't think that eating the stuff is a good idea.

Those are fair assumptions. However, I've been surprised a few times.
For example, I couldn't figure out why I was getting miserable 2.4GHz
performance in an isolated farm house that was 2 miles from the
nearest neighbor or potential source of RF interference. I finally
got around to doing a site survey with a spectrum analyzer and
directional dish antenna. I wound that there was a point to point
2.4GHz wireless link between an office building about 5 miles away,
and an isolated pump house about 3 miles away. The farm house was
directly in the line of sight. At first, I simply changed channels
(1, 6, or 11), but the pump house link changed channel every time the
link faded or was obstructed. So much for adaptive channel selection.
So, I switched to 5GHz, and avoided the problem. Yes, interference
can be a problem in the middle of nowhere.

>No.. The minimum 5GHz channel bandwidth is 5MHz.

Correct. However, 5MHz is not the occupied bandwidth of the signal.
It varies by modulation mode and type. For example, conventional
2.4GHz 802.11b/g is typically about 22MHz wide and occupies four 5MHz
channels. The 2.4GHz band is 83.5MHz wide. Therefore, if it is only
possible to fit 3 non-overlapping 22MHz wide signals in the band
before running out of bandwidth. This is where the recommended CH1,
6, and 11 comes from. Incidentally, picking a channel that lands in
between CH1, 6, or 11 will end up overlapping the two adjacent
channels and interfere with both.

On 5 GHz, it's the same story. You divide the available bandwidth by
the occupied bandwidth of the signal to get the number of available
non-overlapping channels. Diagrams such as these show how it works:
<https://www.google.com/search?q=802.11+channel+bandwidth&tbm=isch>

You can use 20, 40, 80, or 160 on *PARTS* of the 5GHz band. 10 MHz is
available but I don't know any situation where it might be useful. The
bandwidth situation is a mess on 5GHz. I don't have the time to
explain where all the various protocols, power levels, bandwidth
restrictions, and standards, DFS radar protection, etc, fit together.
Also, things get really strange with 802.11ax. See Fig 9:

Go to the column marked United States. Notice that 20 MHz is the
minimum allocated occupied bandwidth. 10 MHz is on the chart, but it
look like no country is using it. 5, 8, 30, and 50 MHz are not on the
chart.

Yep. However, if a wide bandwidth is such a great solution, why
doesn't everyone just setup their routers to use as much occupied
bandwidth as possible, or perhaps just use the entire band? Sure,
there are benefits, but compromises must be made to use a larger part
of the band? Hint: Think about how long a radio needs to be
transmitting in order to deliver (for example) 1 MByte of payload
data. If it can deliver the data twice as fast and therefore uses
half the air time, that's that much more air time for other users of
the bandwidth used.

The question was for an 800ft link.

800ft / 5280ft/mile = 0.152 miles

Please adjust your computation accordingly.

>You can intrude the fresnel by 40% (max), but I try to avoid even that.

That depends on whether the intruding material is absorptive or
reflective. You can get a way with much less clearance if the signal
is absorbed. Yes, the signal level goes down, but it also stays down
and does not vary. However, if it's reflective, then it will refract
(bend) part of the signal, creating the opportunity for fades, nulls,
cancellation, etc. It can also create reinforcement and stronger
signal levels, but those tend to change radically if anything moves.

40% intrusion is a usable number for real links, but only works if you
have a sufficiently large fade margin, also known as SOM (system
operating margin). 20 dB would be a good minimum. I carry 20dB and
30dB attenuators in my toolbox. If the system still works reasonably
well with 20dB loss inserted at one antenna, it will probably be
reliable. If it dies completely, you need a bigger antenna or more
transmit power.

While I'm ranting on the topic, fade margin (or SOM) is related to
reliability (or downtime):

SOM dB Reliability % Downtime per year
8 90 876 hrs
18 99 88 hrs
28 99.9 8.8 hrs
38 99.99 53 minutes
48 99.999 5.3 minutes
58 99.9999 32 seconds

99% reliability might sound great, but that means your link will be
useless for 1% of the year, or 3.6 days per year. Don't go below 20 dB
fade margin, which is 70 hours of downtime per year.

I'll assume a Ubiquiti M5 radio. I have some really old M5-Bullet
radios, with firmware that can't be upgraded to the latest greatest.
However, my house is a mess resulting from my office move, and I'm not
inclined to dig one out and check what it can do. I did some Googling
and found that the Rocket-M5 does support 5 and 10 MHz channel
bandwidth, so I'll assume that your unspecified M5 version also does
the same.
<https://community.ui.com/questions/Channel-width-max-bandwidth-and-max-clients-per-AP/cdf020af-0d11-4982-8c0d-785e3e1c2030>

The article conveniently explains part of the logic behind using wider
channels and mostly answers my question from my previous rant, which
you deleted and/or ignored. Basically, the approximate math is
simple. If your WISP configures their access point for a 40 MHz
bandwidth channel and the ISP has 10 full time connected users, the
system can deliver no more than 4 Mbits/sec to each user. If the WISP
reduces the occupied bandwidth to 5 MHz, and still has 10 full time
users, each one will only get 0.5 MBits/sec, which is inadequate. If
your WISP doesn't have much of a user load, or doesn't overload the
channel with too many wireless users, 5 MHz occupied bandwidth will
work just fine. Note that this simplistic channel loading estimate
ignores various factors that will either increase or decrease the
channel loading. For example, I'm assuming that the channel usage is
sustained at the maximum available rate, which is sometimes a bad
assumption. This becomes really messy if the streaming media provider
adjusts their deliver rate based upon error rate levels returns from
the viewers computer or media player.

Also, there is a problem. This assumes that the WISP has exclusive
use of the channel and that there are no other users on the same
channel. Any co-channel users will appear as interference causing the
WISP access point to lower the data rate to a level where the BER (bit
error rate) is high enough to produce usable throughput. In many
cases, this throughput reduction can be drastic, but for this
discussion, I'll assume it reduces throughput to half. That means
that delivering a given amount of data will double the air time (how
long the transmitter occupies the channel) and delivery will therefore
take twice as long. Actually, it's longer because the packet size is
also reduced, but to keep things simple, I'll ignore that. The result
of slowing down due to interference is that every users connection
slows down, and data takes twice as long to deliver. Instead of ten
happy Netflix viewers, the ISP support phone will have 10 irate
customers complaining of buffering.

So, what can an WISP do? Well, it could not load the channel to the
maximum capacity for a given occupied bandwidth. It could add another
radio on a different channel and move some of the customers there. Or,
it could just size the occupied bandwidth setting to match the actual
channel loading with some overhead left for interference and high
usage peaks.

So, why did your WISP use 5 MHz. None of the advanced 5GHz mode
beyond 802.11a are going to work well crammed into a 5 MHz occupied
bandwidth channel. I'm not sure if 802.11a will work in a 5 MHz
channel. 802.11ac requires an 80 MHz channel. It would be
interesting to sniff the traffic between your Ubiquiti M5-something
radio and the WISP access point with a Wi-Fi Analyzer (Android) or
something similar. My guess(tm) is you're running 802.11a.

So, what kind of performance can one expect in a 5 MHz wide channel
compared to a 20 MHz channel? That would 1/4th the speed *OR* double
the range due to increase in power density (dBm/Hz). That's why it
was attractive to your WISP. Cut the data rate in half yields a range
increase of sqrt(2) or 1.414.

That's also why the FCC and other regulators seem to have purged 5 and
10 MHz occupied bandwidth from the rules-n-regs. It's much too close
to narrow band modulation and carries some of the detrimental effects
of narrow band modulation. It was fine when the typical 5 Ghz signal
used 20 MHz modulation. However, with 40, 80, and 160 MHz now
available, the narrower occupied bandwidths had to go.

That's an input error of (0.2 - 0.152) / 0.2 = 24%
Perhaps using the online calculator which I provided might have been a
better idea? Or maybe a different Fresnel Zone calculator?
<https://www.google.com/search?q=rf+fresnel+zone+calculator>

This is interesting and might explain a few things:
<http://radiomobile.pe1mew.nl/?Calculations:Propagation_calculation:Fresnel_zones>
Since the F2 zone is detrimental to receive signal level,
antenna heights are often selected so that F1 is an
unobstructed path and F2 is obstructed by a hill or the
earth bulge along the path.
In other words, the area around the F1 line is where you get your
usable signal, while the area around the F2 line is where you get your
problems. The reason you can get away with 40% incursion into the F1
zone is that reflecting objects on or near the F1 line will add, not
cancel. I guess it really should be something like:
0.0 to 0.6 F1 = OK. Direct path.
0.6 F1 to 1.4 F1 = problems due to destructive cancellation.
1.4 F1 to 0.6 F2 = OK
1.4 F2 to 0.6 F3 = problems due to destructive cancellation.
I'm not too sure the exact coefficients are correct. I'll check
(later). In other words, there is a "band" straddling the various odd
numbered Fresnel Zone lines which define areas that should not contain
reflective objects.

Which is where I ended up.
Real estate is cheap. Albeit most of it is going to need
