"The LTE network has theoretical data throughput speeds on the forward link of up to 22.7Mbps for a 5 MHz paired channel, based on information from standards bodies, with a typically experienced mean data throughput speed across all geographic areas on the forward link of 1Mbps on a 5 MHz paired channel based on total kilobytes of traffic as measured at the gateway for the period from 6:00 a.m. to 5:00 p.m. The typically experienced mean data throughput speed across all geographic areas for a paired 1.4 MHz LTE carrier is similar to the theoretical peak data rate of our EVDO network based on total kilobytes of traffic as measured at the gateway for the period from 6:00 a.m. to 5:00 p.m.
The actual data speeds of services delivered on the MetroPCS networks will vary, depending on, among other things, the amount of spectrum available to MetroPCS in the major metropolitan area, the type of spectrum used, the configuration of the network, the type of wireless access device used, the usage of the network, the number of users using the network, the distance of the user to the serving cell site, interference, geographic and atmospheric conditions, the speed and capacity of backhaul, and the performance of third party networks and services, including the public Internet. In addition, the data speeds for LTE will vary depending on the bandwidth of the LTE carrier which is devoted to the service, which varies from a paired 1.4 MHz carrier to up to a paired 5 MHz carrier."- VIA METROPCS.COM
