RFWiFi vs. Super WiFi: Key Differences Explained
This article breaks down the differences between standard WiFi and the emerging technology known as Super WiFi. Super WiFi leverages standards like IEEE 802.11af WLAN and IEEE 802.22 WRAN to provide enhanced coverage and penetration. Let’s dive into the specifics.
Key Differences Summarized
Here’s a table comparing the core features of WiFi and Super WiFi:
| Specifications | WiFi | Super WiFi |
|---|---|---|
| Distance Coverage | 100 meters | 400 meters, can extend up to 8 Kms and above |
| Wall Penetration | Lower | Higher (TV white space frequencies penetrate deeper) |
| 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 | 2.4 GHz and 5 GHz | TV bands 470MHz to 790MHz (Europe) and 54MHz to 698MHz (USA) |
| NLOS Performance | Good | Better (due to lower TV white space frequencies) |
| Network Cost | Higher | Lower |
| Power Consumption | Higher | Lower |
| Bandwidth | Lower | Higher |
| Applications | Internet/Data Communication | Same as WiFi, but with higher speed and better penetration in areas with weak WiFi |
Delving Deeper into Super WiFi
Super WiFi aims to solve the common problem of WiFi signals struggling to penetrate walls and other obstacles. It achieves this by using lower frequencies, specifically the “TV white space” frequencies. These frequencies have longer wavelengths, allowing them to bend around obstacles more effectively. Think of it like this: a deep bass sound can travel through walls much easier than a high-pitched sound.
Coverage Area
The extended range of Super WiFi means you can potentially cover larger areas with fewer access points. Imagine a rural area where running cables is expensive or impractical. Super WiFi offers a cost-effective solution for providing internet access over a wider area.
Frequency Bands
Super WiFi utilizes the unused portions of the TV broadcast spectrum. In Europe, this typically falls between 470MHz and 790MHz, while in the USA, it’s between 54MHz and 698MHz. These lower frequencies are the key to its improved penetration capabilities.
