There's plenty of continued debate about the supposed battle between "LTE vs WiMAX".
I suspect the winner will be "both".
There's an interesting comment from Clearwire about this here . And I'm hearing about dual-mode LTE/WiMAX chips and devices.
In fact, I'm forecasting that by the start of next decade, there will be more dual-mode modems and modules sold, than standalone WiMAX ones.
