IEEE 802.22 (WRAN): Broadband wireless connection for the whole city
It looks like the Wi-Fi connection that we all know is about to get a major upgrade. Institute of Electrical and Electronics Engineers (IEEE, read I-Triple-E), the group that brought us the IEEE 802.11 standards or commonly known as the WLAN just published the IEEE 802.22TM standard. IEEE 802.22 will be called Wireless Regional Area Networks (WRANs) that will provide broadband access to wide regional areas around the world.
IEEE 802.22 (WRAN) will use the same technology that is being use on VHF and UHF TV broadcast and will give broadband wireless connection to a large area up to 100 km from the transmitter. IEEE 802.22 (WRAN) will use the so-called white spaces between the occupied TV channels and will have a connection speed up to 22 Mbps per channel without interfering with the reception of existing TV broadcast signal.
This is perfect for densely populated area like rural areas, and developing countries where broadcast TV signal are strong and current wireless connection are no where to be found. IEEE 802.22 (WRAN) can also enable TV stations to become broadband wireless connection provider, in other words an ISP.
