រលក WI-FI អាច​លាត​សន្ធឹង​បាន ១០០​គ.ម.

Super Wi-Fi is inching closer to reality, and now the IEEE, the standards organization responsible for all things Wi-Fi, has published the IEEE 802.22standard.

This new wireless networking standard promises speeds up to 22Mbps to devices as far as 100-kilometers (roughly 62-miles) away from the nearest transmitter. This new band of Wi-Fi on steroids comes through the patch of "white space" frequencies that were previously used to analog television broadcasts.

There’s no word on when and which regions of the United States will be the first to get in on this super Wi-Fi. Houston is currently the only access point for a white space Wi-Fi, which comes courtesy of Rice University researchers. Super Wi-Fi has been slow in coming since the FCC originally approved it back in September 2010.
