Wi-Fi Data Rates, Channels and Capacity

Considerable confusion exists about the performance that Wi-Fi at 5 GHz and at 60 GHz (WiGig) actually deliver. The cause of this confusion stems mostly from the complexity of the interplay of the technical factors involved, as well as the widely different Wi-Fi transmission environments – especially in indoor environments. Another reason is the not uncommon but facile assumption that faster is better. If you asked a road traffic expert whether faster meant better, he would tell you that faster driving means reduced road capacity. Data communications in a shared medium is not very different.
