The problem is...
The lack of backhaul from the wireless AP, to the main network.
It's all well and good to upgrade the wireless data speeds, but as soon as it his the backbone, your speed takes a massive hit.
This is a marketing tool to get people to buty pretty phone data devices, and advertise speeds UP TO 7.2Mbps, when in reality, due to shitty backhaul bandwidth from the cell tower to the main network, you really only get 100-200Kbps
*yawn*
Paris, because she would know more about network management than these muppets
