A Visual Guide to AWS
Replying to: T-Mobile Spectrum? by Jaw3000
I hope I've done a decent job of that with the other key points, but you pointed out an area where the text was relatively weak in guiding readers through the graphics.
Therefore I've just added the following text to clarify the exact question you asked:
No current phones (as of October 2006) are capable of operating in the AWS band.
The chart above also shows why current UMTS 2100 phones aren't compatible with the AWS band. UMTS 2100 phones transmit to towers in 1920-1980 MHz range, which is what towers using the PCS band use to transmit to phones in North America. Therefore UMTS 2100 phones are already designed to not transmit in that range when they're in the US, since that would interfere with PCS networks. Even if that weren't an issue, an AWS network can only "listen" to the 1710-1755 MHz range, so it could never "hear" the 1920-1980 MHz transmissions of a UMTS 2100 phone.
