Its wireless

@co.uk

20Mbps - per sector or base station??

20Mbps - at 3bps/Hz, means 6.6MHz of spectrum at current encoding. I do not see AT&T having 6.6Mhz of spectrum per cell user, they may just have that much per sector.

With LTE, they are quoting 100Mbps in the lab. At 5bps/Mhz that means a 20MHz channel. That channel maps 1:1 to a sector, i.e. a single radio.

So 20Mbps total for a sector with NO other users! Add a dozen voice calls, and you'll be down to 1Mbps.
