Re: Good for them
well there is the 850, 900, 1800, 1900 I wasn't sure what else may be there. It also does not specify if and what different frequencies they use for data or voice and if there is a difference.

| 850/1900 are frequencies licensed for cellular (850) and pcs (1900) communications. Both are used for voice and data.
Here's a overview
»tk.com/wireless/800cell.html
»tk.com/wireless/1900pcs.html
And here's an older breakdown
»www.wirelesswavelength.com/
The issue with 850 MHz band is total amount of spectrum
850 there's 'only' 12.5 MHz base/12.5MHz mobile on A and B licenses. Those that currently have 850 MHz licenses MUST use a portion for Analog service, as required by FCC.
1900 there's 'only' 65 MHz base/65MHz mobile.
Eg. having an 850 MHz license + 10 MHz of PCS is not always as manageable as having the same amount all in the same band. Having to run analog service + having to slice up the spectrum doesn't always work well.
Eg. 35 MHz of PCS on something such as PCS will make 35 MHz of evenly distributed spectrum. Breaking it up into 25 MHz of 850 and another 10 MHz of PCS doesn't work quite as nice.
