This is a fundamental problem of physics and is very, very, very difficult to solve.

The other thing about the uneven spread of wireless, well, that's such a complicated point that it's difficult to answer without writing paragraphs about how wireless networks work at a fundamental level.

In cities we do have, by in large, universal, decent speed wireless broadband. If you've not used HSDPA on the 7.2Mbps standard, try it out. It's impressive.

To keep it short, I suppose I'll deal with what happens if you've got like a cloud mesh. What we've got with LTE and WiMAX is a technology called MIMO. It's basically having multiple antennas working on the same protocol. This is different to how things worked before. Anyway, right now you have one phone antenna talking to one base station antenna at any one time. One data path

The stuff I'm working on will change that. At first, you'll have two antennas talking to two base stations. That gives 4 data paths and thus 4 times faster.
3 phone antennas, 3 base station antennas (or 3 base stations), 9 data paths, 9 times faster.

And so on.

Only problem is, to deal with that level of complexity, you need a vast amount of processing power. Which means more current consumption, more heat, and so on. I can't give details but it's going to be the number one problem with this stuff.

In that environment, cloud computing at a high speed is simple but only for hours at a time.

Sorry if I've rambled on but as it's what I'm working on. We developed the very first LTE mobile phone in the world last feb, can't tell you how long it ran on batteries but let's just say it wasn't long and we had to include a fan.

Cheers I can see now where the issues are , and your right it's complicated which is why a better battery is the simplest solution

* scurries off there to get building the necessary infrastructure for all the base stations and antennae he's going have to have installed to deal with allthe phones on the way .....

Pauses realises he's living in Ireland , which will give him at least 6 months more......
