Verizon EvDO Review
Upstream speeds not as bad as reported
(old news - 01:06PM Tuesday Mar 16 2004)
tags: wireless · bandwidth
The Washington Post offers up a review of Verizon's EvDO broadband wireless service, offering speeds around 500kbps downstream and currently offered only in Washington D.C. and San Diego. The worst performance the reviewer saw was a 540kbps download and a 63kbps upload; normally instead seeing speeds around 650kbps/140kbps. Qualcom whitepapers indicate the maximum data rate for EvDO is 2.4Mbps. The largest criticism of EvDO has been its slow upstream speed, which past reviewers had claimed rarely exceeded dial-up speeds. Verizon's $80 a month EvDO service is expected to go national within a year or two.

Ping Times?

How are ping times though? If they are decent and Verizon can get EvDo Coverage nationwide then I think it'll be great, otherwise, I don't care. Its all up to them whether or not they want to be successful.

Re: Ping Times?

couldn't be worse than t-mobile (600ms+)

but given soem decent amount of mobile bandwidth, its all about low ping times. Even lite websites have too many individual items now for people to put up with high latency.

Re: Ping Times?

Will be interesting to see how much of a fight Nextel's Flarion made FLASH OFDM solution gives Verizon, since the primary benefit of that is supposedly latency less than 20ms.....

That looks very promising. I wonder if Verizon could adopt FLASH OFDM with minimal changes to their equipment, since it has some similarities with CDMA?

Re: Ping Times?

technically they could do it because all it does is use the existing antenna. Just need to add the base station and tie it into thier IP network

Verizon is too slow.

Sprint will be there with something national and reliable before any national verizon rollout.

Re: Verizon is too slow.

And they'll tell you that you can use a datacable with it, while you rack up charges, then after you owe them 400 dollars they'll let you know that you have to have a pccard.

Sprint: the spontaneous provider.

If their data services are anything like their phone services, no thank you. If I had a dime for every dropped call, I'd be retired.

I'll be switching to Verizon real soon now. Been waiting for them to work out the bugs in number portability.

Re: Verizon is too slow.

I don't think so, they have said they are waiting on the much faster EV-DV standard...which isn't done yet, so it will be about two years before they can start their roll out.

Verizon will probably have national EV-DO before NexTel can get FLASH OFDM very far, and NexTel could have FLASH OFDM nationwide before Sprint does EV-DV, but there is no real indication that NexTel will try.

You might like Sprint more, and they may have been first with their current network, but since they can't even start deploying the next network until after VZ claims they will be all done, I wouldn't go betting on Sprint.

Re: Trying soon

I've used Verizon's EVDO in Washington virtually 24/7 since 12/03. It's been generally good and measure routinely see (using various bandwidth sites) download at 350 kbps with occasional peaks of 500kbps. I've seen upload speeds of 80 kbps with high-bandwidth users in P2P file sharing.

However, as happy as I am with it, it is not without problems:

1) The PC5220 card was not compatible with my Compaq 1200z laptop nor a PC adapter I purchased for a Compaq tower. It was compatible only with a Stealth SFF machine I had coincidentally acquired.

2) I experience frustrating, sporadic signal loss that can last for minutes. The problem has not been identified and disappears for weeks at a time. Verizon's first hunch was a faulty PC5220 card. I rotated the SFF machine 30 degrees and it seemed to cure it for a week or so. Might be my location, the PC5220 card or who knows?

3) Inactivity puts the software/PC5220/link into a 'dormant' mode (probably to conserve bandwidth for other users). It takes a fair amount of time to get it active again. I don't have the metrics on this, but someone else at work who also got the service reports that it is unpredictable and bothersome. I would guess that a ping on a 'dormant' link would not look as good as one on an active link.

Even with the problems, I wouldn't (can't) part with it for the relative speed, mobility and privacy it affords me. Also, reports from another user that it works in the Metro underground just fine.

Re: Trying soon

dcEVDOuser,

I found your post to be very interesting.

Do you have a pointer to that other user's report that EV-DO works in the Metro? Do you recall if s/he was actually travelling in a train car, or stationary on a platform?

It would be really amazing technology if EV-DO works in the Metro underground. I would have expected way too much structural and EMI interference in that environment.

I had an opportunity to visit DC last week, and was able to try out the Verizon EV-DO service.

1. It did not work in the Metro. Boarded at the Clarendon (VA) station, got off at Smithsonian. Didn't work sitting on the platform or on the (moving) train.

2. Reverts to 1xRTT mode frequently. But I will say there was a connection of one type or another during most of my (2-day) visit.

3. I really wonder why the upload speed runs so slow ( 100 kbps) and if Verizon can/will do anything about it.

EVDO speeds Greatly Under-Exagerated

My clients are typically experiencing a 110kbps upload and a 800-1200 download. so up load is about basic DSL speeds. What is your experience?
