:Nextgen WiMAX 802.11m will be out by the time LTE makes it out the door. 802.11m is able to do 300Mbps mobile and 1Gbps fixed. Of course individual users will probably not ever really see this.
The challenge for all 4G carriers will be providing enough bandwidth to every site and having enough spectrum. ATT/Verizon only have about 25Mhz or so per market in the 700mhz space. Sprint/Clearwire will have over 100Mhz per market of 4G spectrum.
Talking theoretical MAX makes for good marketing though.
Not to mention that Sprint/Clearwire will have had roughly two years head start on both Verizon and ATT. Xohm will be fully rolled out in many markets long before the first LTE test markets come on line. Sprint/Clearwire might even be rolling out "version 2" of Xohm by the time the LTE crowd gets to the dance floor. Two years is a good amount of time to pick up a few hundred thousand (or well more than that) subscribers, Verizon/ATT should be very careful here!
