WiFi vs Super WiFi-Difference between WiFi and Super WiFi
This page compares WiFi vs Super WiFi and mentions difference between WiFi and Super WiFi technologies. The super wifi is based on IEEE 802.11af WLAN and IEEE 802.22 WRAN standards.
Specifications | WiFi | Super WiFi |
---|---|---|
Distance coverage | 100 meters | 400 meters, can extend upto 8 Kms and above |
Wall penetration | Lower | Higher (i.e. deeper), TV white space frequencies penetrate more deeper compare to wifi signal through more walls and obstacles |
Standard | IEEE 802.11a/b/g/n/ac/ad | IEEE WLAN 802.11af , 802.22 WRAN |
Data Rate | 100 Mbps (11n) to Gbps (11ad) | 25 Mbps (11af) to 40 Mbps(11ah) |
Frequency of Operation | 2.4 GHz and 5 GHz | Operates in TV bands 470MHz to 790MHz (in Europe) and 54MHz to 698MHz (in USA) |
NLOS performance | Good | better than wifi as it uses lower TV white space frequencies |
Network Cost | Higher | Lower |
Power Consumption | Higher | Lower |
Bandwidth | Lower | Higher |
Applications | Internet or data communication | same as wifi but at higher speed and deeper in the rooms where wifi signal is not available |
