[...] Stacey Higginbotham | Monday, November 3, 2008 | 8:13 AM PT | 9 comments Motorola today said it has demonstrated data transmissions in the recently auctioned 700 MHz spectrum using equipment based on the LTE next-generation wireless protocol. The equipment will be ready for limited network deployments in 2009. This puts Motorola ahead of other vendors such as Ericsson, which has demonstrated LTE equipment in the lab on different spectrum bands, and will launch LTE equipment for the 700 MHz spectrum in mid 2009.

Completely agree with Rudolf. The air interface is as efficient as it can get. The bottleneck is the backhaul. People pitch using DSL/Cable as backhaul without realizing that DSL/Cable is not carrier-grade. Other’s said that Ethernet is the solution but you need to put fiber and new equipments on the CO’s. Microwave may be the only option but MW requires licensing, antennas, $$$. There is no easy solution to upgrade the backhaul infrastructure.

OM, the link to "HSPA, LTE and beyond" is broken.

The biggest problem for all this wireless sweetness will be to roll out fibre to backhaul the traffic. You can't do 100mbit/s backhaul over existing copper infrastructure and wireless is at its limits. So at the en of every antenna you do need a fibre. If you envision a future where people will have access to the net regardless of infrastructure. (or different, where you choose an access provider who will provide access over any available infrastructure), than it's easy to see that every curb will need a fibre. No fibre, no mobile broadband.

So start digging!
