Re: ATT is way ahead Ignore people who only see the us as the world.
Wimax is in use in every country even South America and Africa where the infrastructure to support anything else is just not there yet.

Fixed or Mobile?
Again, WiMAX's market will never be anything more than a standardized version of Motorola Canopy. They haven't even agreeded on the VOIP system for circuit switched calls over WiMAX yet. How is a handset going to work on WiMAX unless each WiMAX provider has its own Softphone Software you have to run on the handset?
Oh, and what about WiMAX's spectrum bands? where EVERY COUNTRY AND CARRIER USES A UNIQUE BAND, and the standard has no concept of which bands to use, anything under 66ghz is fine with them.
A WiMAX client hardware is effectivly locked to a carrier by the bands its supports. LTE has its bands already defined, so your not going to see handsets with bands that fit inside an analog TV channel or a walkie talkie channel or a satellite communications channel or whatever license they were able to get their bribe from the local court house since the country doesn't have a functioning FCC.
And LTE already won the PR war, once it has the support of the established carriers, your going to have world roaming with LTE, try that with WiMAX.
And what about all the different WiMAX flavors such as WiBRO and other pre-WiMAX standards? Is there any industry entity responsible for testing WiMAX chipsets from different manufacturers together?

"Sir, your MAC address indicates you have a Motorola client adapter, our network requires Alvarion client adapters sold by us, any others we can not offer support with, I am going to transfer you to sales so you may purchase our recommended adapter" |

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

use a tigo sim card in a verizon world phone , just call them and tell them you want the unlock code for it. Or buy a gsm phone that is unlocked and swap sim cards with either tmobile or at&t and tigo.
I actually can't use my tigo card in the us and im pissed , their so damn cheap it would run me about the same bill i have now.
