Backhaul

700Mb in 60 seconds. On my current tariff, that would cost me £1800. Nice little earner for O2

Batteries.

Backhaul is easy - you put a CDN around your THS sites, then you offer your 700mb movie in 60 seconds yes, but traffic shape everything else.

ok so you might need to upgrade a few microwave's up to 10Meg but it's not the end of the world.

Mobile phone download speeds aren't about phones, it's about having the internet on your laptop or other device on the move, and yes the Backhaul will limit things, along with peak time loads and so on but the future will be something approaching broadband speeds for you laptop when your out and about. Don't be so cynical remember what the internet was like in the days of dial up, and when mobile internet was charged by the kilobyte.

People are already using the 3G mobile based system now for there laptops and desktops (ok mostly laptops) over DSL and cable due to it being more reliable and readily available (ok once they whack up enough decent transmitters).

But what’s the use of this kind of bandwidth on a phone even if display technology gets good enough? it's a technology looking for a use. while using it on a laptop/desktop, or for a replacement for landlines? it will be a much more cost effective system than the big push with some buggered up BT fibre system which won't ever reach anyone outside a major city.

A step towards the MS/Googlesk cloudy everything future maybe? it's a possible.

Ethernet (Microwave) - Good for 100 to 500Mbps. Remember 64QAM in a low power omni-antenna phone in 20MHz scales pretty well on a highly directional 50MHz microwave radio dish.
