LMDS is not the only available microwave backhaul option. But what has T-mobile already done? They announced backhaul agreements with Bright House Networks, FPL FiberNet, IP Networks and Zayo Bandwidth. The have partnered with the cable industry to leverage cable's broadband capacity and extend it to the cell site. Finally they have said they will simply build their own high-capacity microwave. No mention of LMDS as a possibility. Nor mention of using 11 year old junk, naturally!
