The current Internet connections and data requires greater bandwidth, both for a higher participation of users on the networks, both for the gradual increase of content that is increasingly demanding and require large resources (just think of the video in high definition which popularity of YouTube is an example).
What's more, increases day by day the number of wireless devices can connect to the Internet in a comprehensive manner as desktop computers, so the bandwidth of the wireless connection is likely to soon become insufficient. These days the IEEE has finally released and approved the fourth review of the specific Wi-Fi, a new standard called 802.11-2012.
Communication standard Wi-Fi has been significantly expanded, providing increased reliability and speed up to 600 Mbps. The new version will operate on frequencies less crowded than the usual (2.4GHz and 5GHz), in particular exploit the frequencies between 3.65 and 3,7GHz conjunction with an elaborate protocol optimization which required five years of work.
At the moment there are consumer products compatible with the Wi-Fi 802.11-2012, but we hope to start to see some updated hardware in the coming months.
