EVDO Rev A - 3.1mb Down, 1.8mb Up

I have no data on that yet. Qualcomm's chip is too new, so it will take a while for the manufacturers (Lucent, Motorola, Nortel) to build their upgrades. After that, I'm sure the carriers will get an accurate price.

It does not seem possible that Rev A will be available in 2005. I have a friend who works for Verizon and he says these are just rumours.

Plus, as one already mentioned, the upgrades will be expensive and take a long time.

That said, this will be a very important technology. In Rev A areas I cannot imagine many businessmen wanting non-Rev A cards...

Enjoying the forum

QUALCOMM is now sampling the EVDO Rev A chipset to manufacturers, you can read about it here:

QUALCOMM's MSM7500 EVDO Rev A Chip sampling

This still seems like it is far off, maybe there will be cards/phones that support it next year, I wonder how long before Verizon or Sprint implement it? Seems like they will focus on the current EVDO (EVDO Rev 0) and possible start testing in 2006.

Just a rumor for now I think as the short term focus for the SoCal market is getting the 800Mhz voice traffic running at the targeted 85% capacity vice the 95% we are at right now.

Also heard a rumor that some of the unutilized bandwidth on the EVDO will get some voice traffic as an interim fix to keep the network stats from dropping.

$500k for a cell site REV upgrade ... that does sound high. As far as these Nortel BTS's go it would be like a channel element card/T1/carrier add. Plug-n-play.

But ... what do I know

I have heard from friends, that the cost is on the order of 15K per carrier/sector per site. Roughly 50K per site.

So, that isn't as costly as the above guesses.

Not to be a wet blanket, but I would rather Verizon spends their money on rolling out the network nationally before they move to Rev. A. As a 100% on the road guy, I really hate being in cities that still have no EVDO. My guess is we make up the lion's share of the current adopters of cellular modems anyway. If you are not on the road why would you buy this technology? It is expensive, slower, less reliable and higher latency compared to other fixed location options.

And, as far as some of the high data rates you guys claim for EVDO, I am still amazed. I really think you are lucky to get 200K- 300K, which is fine for me. All this 1M download stuff is for the birds and misleads people into thinking they will get that kind of performance with this technology.

One area where I'd also like improvement is in latency before faster speeds. In a perfect world I would have 100% coverage everywhere, unlimted bandwidth and zero latency, but we are not there yet. Until we get there my preference is improving coverage, reliability, latency and speed, in that order.

If WiFi gets the footprint first, I will switch carriers. Fast WiFi with less footprint will not get me to switch.

As a side note...this site totally rocks. The information and repsonsiveness of Michael and the rest of you guys is amazing. If you are not subsidized by the carriers and manufacturers, you should be!

I agree 100%, that Verizon (and others) need to get more coverage before moving on to the next fastest thing. In reality, they will have to. We are *starting* to get some real competition and perhaps later this year and early next, there will be some real choices.

As I said a million times, it will come down to ONE questions:

"Who has the coverage in the places that I NEED IT."

It won't matter who the carrier is, if Sprint is in places next year and Verizon isn't, Sprint will get those customers and vice versa.

I think there will be a real race to get one city on EVDO Rev A, so that one of the carriers can proudly say, "We were first". But again, that isn't going to matter much, coverage is where it is at.

Regarding download speeds over 1mb. Verizon used to claim 300K-600K, they saw most people were getting higher, and now they claim 400K- 700K. There are SO many factors with download speeds. What time of the day are you testing, in a building, in a car, built-in antenna, external antenna, signal amplifier, the weather, the terrain and most importantly, the EVDO congestion. EVDO is a shared environment, if you have a ton of people doing higher bandwidth apps, it will affect your performance. At my house, there are not a lot of EVDO users, and I can usually see 1700K download speeds (Note: This is not average).

WiMax has the marketing behind it, there are just so many question. Many people think, that it will reach 30 miles from a hotspot and have unlimited bandwidth. If your local coffee shop has a DSL or Cable connection, how many users could they really support? I think at some point in 2-3 years, WiMax and EVDO will have some overlap. Someone else said, the carrier that offers both EVDO & WiMax will probably be the big winner.

I am glad you like this site. It was started for one reason, to offer forums for people to get accurate/honest information. When there is a newer bleeding edge technology, giving people the forums to discuss, helps everyone, helps the technology and helps the manufacturers too.

I agree. Coverage is much more important than speed at this juncture presuming a relatively consistent improvement over 1xRTT.

As far as speeds... I generally have been seeing 200-400k in the area that I generally traverse with EVDO coverage. This past week, I happened to fly through Atlanta Hartsfield and noticed an obvious speed improvement. I ran a bandwidth test and sure enough, I was up near 900kbps.

The only thought of coverage versus implementing technology is that you can't do it all at once. They might, in fact, start rolling out the next level as they are finishing the first in some areas. There are probably also problems with getting the quipment built.

Verizon and other carriers are going to do anything they can to keep latency as high as possible. They are afraid of losing there own voice subscribers to Voip. Higher latency is that saftey net. Latency wont improve till the government steps in.
