Super Wi-Fi, also known as IEEE 802.22, is a wireless regional area network standard that operates between 54 and 862 MHz in the VHF and UHF TV white space channels. This technology uses cognitive radio principles, making it faster and more reliable than traditional Wi-Fi systems in certain areas.
In comparison to IEEE 802.11af Wi-Fi, which also utilizes TV white spaces, Super Wi-Fi has longer ranges and faster data speeds. It is capable of reaching up to 100 km and delivering speeds of 50+ Mbps, compared to 1 km and 25+ Mbps with 802.11af. Both systems are able to achieve better throughput through walls than standard Wi-Fi due to their lower frequencies.
Super Wi-Fi has the potential to revolutionize internet connectivity in rural areas where traditional Wi-Fi signals may not reach. By utilizing TV white spaces, Super Wi-Fi can make use of previously unused frequency channels, providing a more reliable and faster connection to users in these areas.
