Re: ATT is way ahead said by BosstonesOwn:You do know that the wimax gear is almost like wifi right ? it can use multiple channels and auto tune to the channel. depending on the country where it is in use the adapter will be specific , just like wifi. The only thing WiMAX has in common with Wifi is ethernet frames, having a point to multipoint architecture, and being wireless clients around a base station, and being assigned under the IEEE 802 standard family. Thats about it.
WiMAX is related to Token Ring, as Bluetooth is ISDN Ethernet AKA IsoEthernet.
Wifi uses a single frequency band, 2.4 ghz.
All wifi chips are capable of the full wifi band, firmware selects the particular channel. The channels are in linear order.

The same circuit and antenna will work for all wifi channels.
Totally different story with WiMAX, try comparing a DBS/Dish Network/DirecTv LNB/radio/receiver to CB Radio, try to make the same chip/circuit and the same antenna work on both frequencies. | | |

| 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.
I work with this stuff daily
