Verizon runs under a CDMA Network--it chews up your Cell Minutes while
you are browsing through the web, according to the video, you have to
wait about 12 seconds before you even communicate through PTT....Very
questionable reason why Solo CDMA is slow.... Also keep in mind that
Verizon is a Tri-Mode Provider as well, so for the best results, you
will need a Tri-Mode Phone that supports AMPS, CDMA, and PCS.
Sprint runs under an all-digital PCS System but is just as fast as
Nextel (rumored). The only thing you should keep in mind is that with
Sprint's Web Services, it will also chew up your Voice Minutes, so you
have to choose your options carefully. I am unsure how Sprint's
Walkie-Talkie features work, though. Sprint's two band frequencies are
CDMA and PCS, primarily PCS.
The guy that he was testing Nextel's Direct Connect Goodies is with the
Clamshell i730 and the Candy-Bar i205. It's pretty instant, especially
when you need to alert someone of a missing homework or something. Keep
in mind that Verizon, Sprint, and Nextel runs under different protocols,
meaning that the speed and the quality of Cellular and Push-To-Talk will
vary. Sprint runs under Dual-Band, All-Digital PCS, Verizon runs under
a Tri-Mode, Dual-Band CDMA and AMPS, and Nextel runs under Motorola
iDEN, which is a foundation of many Cellular Telephone Protocols, and
Mobile Web Protocols in one provider.
So Protocol Awareness should be a buying factor IMO, but you have to be
aware that you if you want Push-To-Talk, you will need to look inside
each of the service protocols (Verizon's three-mode, two-band
CDMA/AMPS/PCS Network, Sprint's All-Digital, Dual-Band CDMA/PCS, and
Nextel's iDEN, a blend of 5-6 cellular protocols in one) before you make
a final decision. For urgency issues, you definitely should consider
getting a Nextel Phone, since iDEN was made for urgency and productivity.
These adverse factors affect a buying decision:
* Price
* Push-To-Talk Instancy
* Features
* Selection of Phones
* Fancy "Doo-Dads"
I don't know what the order of what affects your buying decision is, but
feel free to debate. Many college students at DeVry just simply
overlook (especially myself in the past) the usefulness of a Nextel
Phone, and it's pretty much a handy tool so that instructors can
actually tell you via DirectConnect what you have missed out on, etc.
With homework urgency in mind, what do you guys think should college
students get assuming that a professor has a Nextel Phone "armed"?
Sprint is 100% 1900MHz PCS
Using Qualcom's CDMA digital transmission protocol.
1 frequency (band), 1 protocol CDMA
You are grossly mis-informed.
BTW, it is the exact same technology that VZW uses, but VZW
uses both 800MHz and 1900MHz, depending on the area.
#1 800 AMPS, #2 800 CDMA, #3 1900 CDMA, this the "tri"
The PTT may differ, but the regular voice on BOTH is CDMA.

At the end of the clip, it says they also tried SPCS and SPCS is as fast as
Nextel.
Sounds like Verizon's rush to release PTT hurt them.

Um.
Sprint and Verizon use *the same* protocol. CDMA (for the PTT services,
CDMA 1xRTT). Verizon uses 800 in most markets, 1900MHz in a few. SPCS is
all 1900MHz. But it's all CDMA. You can't use PTT on either Sprint or Verizon
if your phone is using an analog signal, so that's irrelevant (and on Sprint,
if you're analog, you're roaming and probably not able to use PTT anyhow).
I'd like to see a similar test done by TechTV, between Nextel and Sprint.

iDEN is a hybrid of cellular and SMR two-way radio technology. Nextel's
service is (Obviously!) several years more mature than that of the CDMA
carriers.
The point that Nextel's coverage isn't as good as the pure cellular/"PCS"
carriers' coverage is one that shouldn't be ignored, however, if you are
intending to use the phone as a phone as well as a two-way radio.
> Take a look and you judge the performance difference.
My work switched from Nextel to Verizon for PTT due to degrading coverage
of Nextel at one of our sites. Here are my opinions...
Pros:
* Nice to see who is online when scrolling through the list.
* Better coverage. At one of our sites, Nextel didn't work well at all. I
usually would have to walk out of my office and down the hall to talk.
* National service included, Nextel costs more and if you don't pay for it,
if someone happens to be outside local area and you PTT them, you get
charged even though you don't know they are outside the area
* Group 2-way is nice. It's free (currently) on verizon
* The v60p has a lot more features than the i1000 pluses we were using.
* More cellular minutes, including 1000 mobile-to-mobile, which I think
we'll be using more cause PTT sucks so bad. Oh wait, getting ahead of
myself here... The v60p has voice dialing so it's a lot easier just to
push the voice button, speak someone's name, turn on speaker phone and use
it as a normal phone
Cons:
* Battery life on the v60p is REALLY REALLY BAD. Can't last a day with
normal use. And if you plug it in to charge with the phone on, it takes
hours to charge.
* Slow push-to-talk response time is horrible. The initial connect time is
the worse. Once the connection is set up, it's about a second delay each
way. You kinda get used to it after a while, but still a pain. My crew is
using the cell minutes up basically. Hopefully we don't go over, else our
business office is going to crucify us.
* The v60p seems a lot flimsier than the i1000s which took some real
punishing abuse from all of us. I already dropped the v60 and the clam
shell popped off and the battery went flying. At least it still works. I
was surprised.
* The phone clip that the v60p comes with is horrible. With the i1000, you
could easily get the phone out of the clip and back in. The v60 you
basically have to break a finger or end up pushing buttons on the side of
the phone as you try to pry it out. I read elsewhere on the net that it
slowly gets better after a while and then eventually starts coming out of
the clip all on its own. :(
Yeah, I would be weary, too. I hear Verizon is aggressive in defending
it's network, and is willing to sue the average Joe for all his
(positive) networth.

I thought Sprint ran on two frequencies.....Hmmmm.....I guess I was
wrong--Sprint runs under 100% 1900MHz PCS......
You're kidding. I thought that PCS and CDMA are different protocols,
different transmission methods, algorithms, and cell phone schematics.
LG's Cell Phone Website dictates that their phones for use with
Verizon's network says "For use with Verizon Wireless 800MHz AMPS,
800MHz CDMA, and 1900MHz PCS networks".
So both PCS and CDMA use the same transmission methods, algorithms, and
Cell Phone Schematics? Or is it because Verizon's phones and Sprint's
phones uses different cellular telephone schematics?
PCS means 1900 MHz - just the frequency range. It implies nothing
about the modulation method, etc.
GSM is also offered in the PCS band.
PCS is a marketing term, in my opinion, but the FCC uses it too. But it
just refers to the *frequency.* (1900 MHz)
AT&T has marketed their phones as Digital PCS for years and they use TDMA
(and now GSM), completely different cellular protocols, but they are mostly
1900 MHz so the designation fits. Sprint is all 1900.
> So both PCS and CDMA use the same transmission methods, algorithms, and

No. Stop thinking of PCS as a separate protocol. The PCS frequency is used
by GSM, CDMA and TDMA carriers.
Verizon, Sprint, Alltel, and a few smaller carriers all use CDMA.
PCS refers *only* to the fact that a phone is using 1900 MHz. It could be
running on any of the digital protocols at that frequency.
Exactly. Sprint took more time, so I wouldn't be surprised if they had the
better service.
Don't forget that US Cellular uses CDMA as well. So PCS is actually
just a 1900MHz Frequency Subsidiary of a particular protocol?
When AT&T started calling their 800Mhz TDMA "Digital PCS"
this screwed up whatever definition the term ever had.
PCS was SUPPOSED to refer to any digital services in the 1900Mhz frequencies.
NOT any particular protocol, "band", carrier, phone or whatever.

Actually, wasn't PCS supposed to refer to any "Personal Communications
System" no matter what frequency it was? This was even before the FCC
auctioned off 1900 blocks.

Assuming you can find someone else that has it. It's likely that
the largest majority of true "business" users will stay with the
NexTel unless Sprint severely undercuts on cost.

That's what I thought too, so when I saw AT&T claiming PCS on 800 MHz,
I thought they were a little liberal in their terminology. Eventual
research showed that PCS generically refers to an enhanced
communications service (my words as I don't recall the exact wording)
such as SMS.
This was like seven years ago - about the same time Sprint hit
the Dallas market. I believe AT&T is all 1900 MHz here now.
Nextel uses two-way radio frequencies, not telephone frequencies. I am
not sure, but I don't think that there is any spectrum for two-ways in 1900.
--
Thomas M. Goethe
That would not prevent them from developing a dual frequency phone- one for
cellular and another for DC. They could then utilize 1900MHz and continue
to use the two-way spectrum.
I believe their proposal to the government regarding eliminating public
safety interference asks for a swap to 1900MHz, IIRC.
You're right. Its the different cell phone schematics. Also Verizon and
Sprint use different framulators. But the biggest difference is in their flux
capacitors... Verizon gets theirs from Yoyodyne in New Jersey...
And they operate at 1900 "Gee-ga" hertz.

Um.
For PTT, not exactly. While they do both use CDMA, PTT is clearly not a
switched network solution. It uses an SIP-based system, and both
companies went with different vendors to provide this solution.

It's also potentially on its way out. Nextel has made no secret of the
fact that they too are looking into an eventual migration of their
network to some variant of CDMA, including CDMA2000 1x.
See:
http://telephonyonline.com/ar/telecom_nextel_continues_pursuit/
The current deployment of WiDEN is largely a stopgap to speed up their
data rates, and while it *may* double their voice capacity (though
they've seemed to not boast about it lately), they're still at a serious
capacity disadvantage to CDMA.
My point? As Nextel continues to see more customers sign up, service
will degrade. And the long term solution is a costly transition to an
incompatible standard, which will mean forced handset upgrades over
time. And who knows? They may end up using an SIP-based system similar
to what Verizon and Sprint are using now.

But I think this reply was to one of my posts, and I was referring to the
fact that Verizon and Sprint both do use CDMA... ok, yes, PTT implementations
may be different, but the networks are both CDMA networks.
IIRC, and without more context it's hard to tell (and too late for me to
remember), someone upthread said that PCS and CDMA were different protocols.
I thought someone asking about that.
But, no, they're not. They're as related as CPU speed and

I work for SprintPCS
I *don't* speak for them.
* NextelOne--Creator of iDEN-Ready Hardware
* NextelSource--actual iDEN Service Provider
Know that some ideas could be too big for Nextel and Motorola to handle
alone, so IMO there should be a box that dedicates 100% of the
iDEN-ready Hardware, hence NextelOne. Furthermore, there should be
another box that dedicates 100% of the actual iDEN Technology
development, called NextelSource.
AFAIK I think that an iDEN Association (a collaboration of iDEN
Providers, Nextel and SouthernLINC being the only iDEN Providers to
date) would be great as well.

Uhh, no. Sprint Vision service is separate from your MOU and will not
chew up your voice minutes.

Wow, you know nothing about PCS. :)
"PCS" is the frequency band Sprint uses, namely 1900MHZ. CDMA is the
signaling format. They use one band, one signaling format.
Additionally, your earlier statement that for Verizon you need a
tri-mode "AMPS, CDMA, PCS" phone to get the best results with PTT is
also untrue. PTT will NOT work under AMPS. It will only work under
CDMA, and only if you're on an the enhanced 1x network.
Of course, neither Nextel's nor Sprint's PTT will work under AMPS either. :)
Finally, I have used Sprint's ReadyLink service. It's NOT as immediate
as Nextel's service. It is however, fairly close to equal, and "good
enough" for what I use it for. I imagine a lot of people will be of the
same mind. The only drawback is the Sprint currently limits group calls
to 5 people, where Nextel (I believe) imposes no such limit.

Either TechTV's video link has the same latency at Nextel's Direct
Connect, or they did a little fancy editing. Yes, Nextel's service IS
fast, but not instant. All you need are two Nextel phones in the same
room to figure that out. There's usually a half second delay or so.
Of course, that IS insignificant for most people, but still sloppy on
TechTV's part.

*sigh* No, Sprint runs on a single band. Dual-band phones on Sprint
are dual-band only for the purpose of roaming on 800Mhz with other
carriers. VZW does have both the 800 and 1900Mhz bands which they've
deployed CDMA on, as well as AMPS on 800MHz.
> a Tri-Mode, Dual-Band CDMA and AMPS, and Nextel runs under Motorola
> iDEN, which is a foundation of many Cellular Telephone Protocols,
You're kidding, right? iDEN was originally designed as an SMR protocol,
NOT cellular. The duplex telephone feature was a side-service. It just
so happened that the cellular feature was what people wanted more than
the Direct Connect feature (though it's popular now as well), so some
kludging had to be done to reposition iDEN is primarily a cellular
protocol with walkie-talkie capability.
If you were right (and thankfully you're not), the wireless industry in
the us would be in one SORRY state. :)
Actually, Extend America is another iDEN provider. They are
headquarterd in Bismarck, North Dakota and thier website is
www.extendamerica.com
==AD
Actually, it would stand to reason that TechTV's video link has about
teh same latency at Nextel's DC. You have to remember, TechTV could be
broadcasting from one location to another on up to three satellites
(most likey one thought) and so no matter what, it would have a latency.
I did satellite braodcasts for a year, and the locations were only 250
miles apart, and there was a 2 second (each way) latency. If we turned
our volume up, we could hear our voice echo 4 seconds later.

Heh. And assuming we go with the PalmSource/PalmOne model, does this
also mean that Nextel is going to go through several years of
squandering their resources, refusing to innovate, and massive layoffs
before they finally get their act together, leaving everyone to wonder
whether it's too late for a full recovery? :)
Oh wait, Nextel is already blindly refusing to innovate by continuing to
use iDEN. So they are in fact well on the path. :)
