Sprint CTO Barry West regards WiMax the 4G technology because not only is it faster, it is also cheaper. According to West, WiMax causes a 10-fold improvement in the price-per-bit as it uses a wider channel. The current CDMA networks run on a 1.25-MHz channel and can deliver a maximum of 4 bits per hertz, or around 5Mbit/s at the base station. WiMax, on the other hand, makes use of a 10-MHz channel, thus it can generate a total of 40Mbit/s.
