Hmm, Motorola aren't doing too badly out of this. The fact that every year that Airwave is extended earns more money than ESN will over the entire contract might make some people think that there could possibly be a conflict of interest?
The next issue - EE's contract to provide runs out at the same time as Airwave ends. What is the realistic chance of that contract being available to competitors at that point - from a practical point of view? Zero?
