huh ? nope EDGE is everywhere such as rural towns but in cities there are 3G(HSDPA, UTMS, HSPA), not EDGE. HSDPA and HSPA are 3.5G.

Like deafclimber said, I just noticed that att has rolling out the 3G in 2006.

Yup, USA is very big country, it taking so longer for small to medium cities to get 3G and att's 3G is currently spreading to suburb, some part of exurb and some middle cities.

EDGE isn't 3G but rather to call 2.5G or 2.75G but 3G HSPDA is faster than EVDO.

Lateness in 3G game is probably due to limited bandwidth.. Thats why 700 Mhz is used for future growth. ATT and Verizon are the BIGGEST winner in 700 Mhz game.

yes that is correct. Verizon is pretty aggressive.
Oh, got it and thanks to both of you.

I feel bad for t-mobile about waste of their time from government.

Which is more bandwidth? 1700 MHz or 850 MHz/1900 MHz?

Deafclimber, does Verizon will use GPRS/EDGE, along with LTE when LTE isn't serve in some area?

Download theoretical peaks
Rev0 - 2.4Mbps
RevA - 3.1Mbps

Upload theoretical peaks
Rev0 - 144Kbps
RevA - 1.8Mbps

Latency (lower is better)
Rev0 - 150ms-400ms or higher
RevA - as low as 50ms in best cases
HSDPA - 120ms-400ms or higher


But again, I dont have HSPDA and really can't comment much about it. I only really can comment on EVDO side as I work with it at my job.

Keep in mind, comparing speed tests for different tech is like comparing apple and orange. Also, limiting factors is transport capacty at each cell site.. Most cell sites typically carry only two T1 for DATA only which limits to 3mbps and it SHARES with other users. Bigger sites may carry more capacty as needed. Smaller site only have ONE T1 (1.5mbps MAX)..

Also, if you are TOO close to cell site, you will get CRAP speed compared to 100-500 feets away. Reason for that, if you are too close to between 2 sectors or in between 2 cell sites, your phone ping-pong handoff between these 2 sites which affects perforance.

that is a good question but i cant answer that because there is not enough information in my wireless researching field. in my opinion, verizon's mobiles will have both LTC and CDMA in it.

same idea with att's mobiles that come with EDGE, HSDPA, GSM/GPRS.

Not in average?

When I had test with 2 previous phone, att Tilt and Sprint Mogul on my MacBook Pro, I got between 1.4 to 1.6 mbps via att's 3G and 800 kbps to 1.2 mbps via Sprint's EVDO but upload is around 100 to 300 kbps and latency is between 150 to 300 ms on both of carriers.

3G in Europe like UK is more superior than in USA, HSDPA can be go up to 14 mbps.

I disagree.. 800Mhz band has more bandwidth than the PCS. Also it is matter of how effective the carrier use the bandwidth too.

richarddeaf, i understand you work for wireless company and you think EVDO is the better. then that is fine. that is your opinion and i respect that.

however i stand correct that att does have GSM's 3G networks.

btw i work for att mobility.

google.com is our best friend that you can find more info about UTMS/HSPA. like for instance, they say HSUPA goes 7.5mbps down and 2.0 up.

i am aware of that. i just say in general way. they are no diff. if he questions the size. then i wud know, but really there is no diff. like 1700 is better than 1900. it depends on what FCC authorizes what frequencies wireless carriers can get.

I have nothing against GSM or HSPDA, there are quite few different technologies out there.. I am just maintenance the EVDO equipements.

What job position do you work at ATT Mobility? I work in network operations (Switch), worked there for 11+ years. I would LOVE to know and meet other "deaf" switch engineers. As far I am aware, i am only one in my company.

Here's the latest on Suncom and T-Mobile:

SunCom | T-Mobile Merger

As for acquiring Sprint, here's my opinion:

Sprint is run by a bunch of crooks. Bleh!

If T-Mobile already took over Suncom, how come their website hasn't changed, we customers are still under Suncom, and there are no T-Mobile stores within 50 miles of this part of SC?

We don't know when they will change the name to "T-Mobile" . but you can buy SK3 or Blackberry to T-mobile in VA, GA and other state offers T-mobile.

T-mobile device will not charge thorugh Suncom Network. it just under unlimited data service on SK3 and Blackberry.

Suncom is not heard in Wyoming I never heard of the wireless company.

I hardly remember first term many years ago President Bush said all wireless will be change by 2010 and my guess that something is big change in future of Homeland security?
