Verizon Responds to AT&T Suit, Calls It 'Meritless'
sigh...bad for ATT
What a shame...
If Verizon Wireless were to have ANY phones that people actually used data on, they'd be suffering far more outages.
Verizon Wireless also didn't build out much of their network- Alltel did, and they just inherited it from Alltel (smart move) , or pulled it from Sprint. AT&T's only partner with wireless T-Mobile, has been laggard.

The solution is simple. Free the iphone from AT&T's clutches and let's put your theory to the test.
1x = voice (850MHz)
EVDO = data (1900MHz)
GSM/EDGE = voice/data mixed on 850/1900
3G UMTS/HSPA voice/data mixed on 850/1900
Sure data is only on 1900MHz, but as long as voice and data works, who cares. Voice is typically more sensitive to QoS than data. To the average consumer, it does not matter, as long as it works. 3G voice on 1900MHz only blew chunks because of capacity (only 5MHz) and poor signal.
Again, people don't care that VZW purchased VZW, they just care whether service works where they need it.
850 is often referred to as 800.
Also, 1X and EVDO can operate on either 850 or 1900.
ATT's 3G GSM runs 850, 1900, and 2100. 2100 is solely for one direction, 850 or 1900 for the other direction. This means that an extra radio has to run to run 3G on GSM. Adds a bit more battery drain too.
GSM, CDMA, HSPA/UMTS, EVDO, etc can ALL run in either the 850 (or 800 if you like), PCS (aka 1900) or AWS (1700/2100 MHz) bands. If a carrier (like T-Mo) chooses to deploy in the AWS band, then their tower-to-mobile transmission is in the 2100 block and the mobile-to-tower transmission is in the 1700 block. However, if deployed in the 850/800 or PCS/1900 bands, both directions have frequencies within those same bands. For example, B Band in the 850 spectrum will use 880-890 MHz for tower-to-mobile and 835-845 MHz for mobile-to-tower; PCS B Block will use 1950-1965 MHz for tower-to-mobile and 1870-1885 for mobile-to-tower.
And the extra battery drain when running 3G GSM is because the technology is W-CDMA based. CDMA uses sig...
I am not in an Alltel area at all.
