said by r81984:4G to a lay person means up to 100 Mbit/s for moble devices and up to 1 Gbit/s for stationary devices.
I call BS on that suggestion. Please point me to a layperson (e.g. basic iPhone user) that knows about some obscure, now irrelevant from a marketing point of view, technical specification. For that matter, show me one of these people that understands what 3G or even 2G means.
