Re: ATT is way ahead the newer wimax chips also can take in any channel in the wimax range.
the only difference is the antenna and how the adapter is set up.
I used wimax in Colombia and Australia for almost a year. I also used wimax in France for 4 months.
The same wimax adapter from Colombia worked in Australia , Even though Colombia was 5.8 and 5.9 while Australia was using 2.8 to 3.2 , thats an awful big hop. And yes the antennas did need to be changed. But that was because I had beta equipment. Yes I worked on wimax for many carriers.
The newest wimax gear can go anywhere in the world. Motorola's USBW 100 is a prime example , it is a usb thumbstick that can recieve wimax any where in the world. I have one sitting on my desk in front of me that was given to me by the clearwire engineers.
And btw , the handsets treat the wimax signal as data only. The handsets have sip settings to back end it to the sip call servers in the carriers data center. Once the call is actually acked , it is treated just like a voip call over sip.
