At the same time the speeds of cellular networks keep increasing with the establishment of 3G networks and the recent announcement of soon to be deployed 4G networks which will have speeds up to 1.5 megabits per second. However, advancements in established 802.11 Wi-Fi mesh networking technology could overtake the cellular phone system by providing a more efficient and cheaper network while providing a faster, more flexible, more reliable and more useful network.
