There has been a lot of debate over the current 4G situation across the networks in the U.S. AT&T, T-Mobile and Verizon claim to each have 4G networks, or planning such networks, but that hasn't stopped Sprint coming out and stating in a recent video that they are the only carrier with a true 4G network.
”Other carriers might claim to have a 4G network, but right now Sprint is the only national carrier with a true 4G network.”
In the video found below, Sprint is discussing the availability of it's WiMax 4G network that has just been unleashed in Los Angeles. We see Michael Galluccio, Sprint's Sales Manager New York Metro, using pipes as a visual reference for how each carriers network can perform. Sprint simply stated that 4G is about capacity, a capacity in which they have the upper hand in.
Also of note from the video, we learn from Teresa Kellett, Director of Sprint 4G, that we will be seeing a lot more 4G in the coming months. In fact, we will have 4G all the way east to Ontario, and then as far south as Anaheim, Santa Ana, and Huntington Beach.
