Verizon High Speed Wireless
TheSync writes: "Wired News has an article about Verizon's surprise announcement of "Express Network," a wireless data service with a speed of 144 kbps. Handsets to support the service could be sold as early as next week, and Emblaze Systems is already testing wireless video on Verizon's Philadelphia network." I'm sure it will work just as well as Verizon's cell service does now.
"I'm sure it will work just as well as Verizon's cell service does now."
Why is it that companies insist on rolling out new "services" when they never got their old services working correctly. Cox.net is doing this now by telling us all that we are going to go really fast real soon, ignorring the fact that most people can barely get online and hold times for customer service are almost 2 hours.
The reason is pure greed. To make their existing products work they would have to spend money on infrastructure and upgrades. A new service is mostly marketting and great launch parties. New serices make a CEO look good to the stock holder while hiding the fact that their network is held together by Duct tape and sneaker nets. I say boycott this crap, I have told a cox rep at my work to his face that I did not feel good about installing a T3 from them because my home service was so bogged down, telling me their network sucks.
It's time we let corporations know that we want the old stuff to work correctly before we will buy their new crap. Send a message that poor service and flawed products are not the way to win us over.

I don't know where you live, but here in NYC Verizon is the best cell carrier out of the bunch. Only time I've ever had a busy signal was on Sept 11th, and I get a signal almost everywhere I go. Unlike ATT, Sprint and Nextel around here.
This is definitely coming off of existing cell phone towers. Those are very far apart (less maintenance costs, etc.)

What VeriZontal Wireless is introducing is the so-called "1XRTT" form of CDMA2000, which is one of the flavors of "third generation" (3G) cellular telephony. While there has been a lot of noise about 3G around the world, and European carriers have shelled out tens of billions of licenses (dotcom-style investment) for new 3G spectrum (putting them deeply into debt), VeriZontal Wireless and Sprint PCS are instead taking the "just do it" approach.
There are two distinct technical flavors (air interfaces) to 3G, both based on CDMA. The GSM (most of world) and IS-136-TDMA (Cingular, ATT-W) carriers, with existing TDMA networks, are migrating to WCDMA. The CDMA carriers (Sprint, VZW, Korea) are migrating to CDMA2000. (Qualcomm favors CDMA2000, but makes patent royalties off of both. They really did invent it.) The CDMA2000 spec in turn has multiple variants. The "1XRTT" flavor is simply a software change to the way existing CDMAone carriers are allocated among calls. The peak speed is only 144 kbps (ten times what CDMA one gives you) but there's no forklift upgrade, and no new spectrum needed. Of course it needs new handsets to make use of the new features, but the base stations are backwards compatible. Very graceful, 3G on the cheap.
So VZW and Sprint are both rolling out 1XRTT this year. VZW announced faster, but they're both gated, in practice, by the availability of handsets and similar remote devices from the (mostly Korean) makers. The CDMA and GSM carriers are instead phasing in a "2 1/2G" technology, EDGE, as a sort of bridge to WCDMA. They'll need separate networks, or a forklift upgrade, to do 3G. Since WCDMA doesn't share spectrum with TDMA, they can't do the easy phase-in that CDMA gives you.
But don't think of 3G as a substitute for fast wireline. A 144 kbps call basically eats ten voice calls' worth of network bandwidth. So it will be expensive! Packetized data, by the byte, will be cheaper, but really aimed more at low-bandwidth things like email than high-bandwidth things like music or ordinary web browsing. (Look up EDGE pricing on the GSM networks to get an idea; it's in dollars/MB). This is a premium service for users who need it.
Well, 802.11x and "High-speed wireless" are different technologies with different goals. 802.11x targets users that aren't necessarily moving around that much, and is not that secure (image is of laptop at home, it's nice outside, so you wander out on the porch or backyard)
With "High-speed wireless" the idea is to use the existing cellular network and provide data access.
Oh, and the 144kbps? Don't count on it! They should say 144kbps aggregate bandwidth for the cell shared among all users on that cell. It's a typical marketing scam. Saw this at a trade show, and when I asked more detailed questions, the whole sales pitch fell apart.
Although I don't live in that area, it doesn't suprise me that they are using the term "1x" What they are actually referring to is "CDMA 2000-1XEV". The "EV" stands for "Enhanced Voice". It has a maximum data capability of 144kbps.
For all of the posters that have requested higher data-rates; don't worry, it's coming:
WCDMA: Wideband CDMA. It wil start to appear in Europe and some US networks later this year (IIRC). It will have a maximum data rate of 384Kbps (IIRC). However, it uses almost 5MHz of the spectrum (~2.5 forward link + ~2.5 on the reverse link)
1X-EV+DO: The add-on to the CDMA standard should allow data rates of between 1 & 2 Mbps. It's commonly reffered to as High Data Rate (HDR) and could appear late this year or sometime next year.
1xDV: This probably won't be out until 2003-2004 timeframe, but it should offer enhanced voice and data speeds. I don't think that the spec is totally finalized, but it could provide data speeds up to 10Mbps.
Doh!
What I don't get is why this article keeps harping on phones. Who needs 144kbps to your phone? Streaming video? Who is going to watch video on their phone? You can't browser. E-mail is possible, but not all that interesting.
Show me a PCMCIA adapter for my laptop, and then I get interested. Even a pocket PC might semi-interesting (although browsing would still suck, I'd imagine).
Sometimes it's best to just let stupid people be stupid.
How about two?

I work for Lucent and have been deploying this technology for companies such as Verizon and Sprint for the last few months. The technology Verizon is announcing is known as 3G-1XRTT. There is another 3G technology, 3G-1XEV-DO, which will be available soon. 3G-1XRTT supports speeds up to 144kbps. 3G-1XEV increases this to 2.4gig. The way that 1XRTT actually works is that each user gets one 9.6kbps channel when they connect. Then, when the user is transfering data, the cell site or the handset can request to "burst." The speed at which you burst depends on how much data you're transferring and how many resources are available on the cell. This burst speed can be any multiple of 9.6 up to 144kbps. Bursts only last for a few seconds (typically 5 or less). After that the cell/handset have to negotiate another burst. This is because as you might imagine, this can use a lot of resources on the cell/switch. For this reason, if you are not transfering any data for a few seconds, your call will go into a dormancy state. This means that all of the resources on the cell are released and your airlink is dropped. However, the call is still registered on the switch. So, when you go to transfer more data, the call comes back up and you don't have to be authenticated again or reregistered on the switch. It's a very cool system that can use a lot of resources but only when it really needs them.
I'm sure you're all wondering what kind of throughput you can really expect to see from this. In my tests I typically see rates of about 11-12KBps. You may not see speeds quite that good in an area where a lot of people are using wireless services but I'd expect most people to see speeds about that fast. It's not as fast as cable or DSL but it's at least twice the speed of a 56K dailup - pretty darn fast for a wireless phone.
I speak for myself and not for Lucent.
