Introduction:
Even though the IEEE 802.11be standard is yet to be released officially, there are currently Wi-Fi 7 routers on the market from many major vendors. Wi-Fi 7 provides significantly faster speeds then WiFi 6 (IEEE 802.11ax), with ultra-low latencies and a better communication channel. Thereby, more devices can be connected efficiently.
Wi-Fi 7 routers are capable of delivering wireless data transfer speeds of up to 46 Gbps, which is five times greater than that of Wi-Fi 6E routers. Wi-Fi 7 routers can also operate on multiple bands: carrier frequency operation is between 1 and 7.250 GHz while ensuring backward compatibility and coexistence with legacy IEEE Std 802.11 compliant devices operating in the 2.4 GHz, 5 GHz, and 6 GHz bands. Latency is also lower with a Wi-Fi 7 router and channel connections are more efficient.
Some Wi-Fi 7 routers include the NETGEAR Nighthawk Tri-Band WiFi 7 Router BE19000 Wireless Speed, the TP-Link BE9300 Tri-Band Wi-Fi 7 Router ARCHER BE550, and the ASUS BE96U Tri-Band WiFi 7 Router RT-BE96U.
6 GHz Band Controversy:
As of September 2023, the following countries have adopted the policy of making the entire 6 GHz band available for unlicensed use: U.S., South Korea, Brazil, Saudi Arabia, Costa Rica, Peru. Canada has also made 1200 MHz of 6 GHz spectrum available for unlicensed services. The 6 GHz band is the largest allocation of unlicensed spectrum in the US and South Korea.
Some other countries that have enabled Wi-Fi in the 6 GHz band include: Andorra, Argentina, Australia, Austria, Bahrain, Belgium, CEPT.
China has chosen a licensed approach for the 6 GHz band, using the entire 1,200 MHz for 5G and future 6G services.
The Telecom Regulatory Authority of India (Trai) suggests that the lower end of the 6 GHz spectrum band can be allocated for unlicensed use, such as WiFi, while the upper end can be licensed for telecom use. Netgear said that the India DoT (Department of Telecommunications) is considering to delicense the lower band 6 GHz spectrum.
However, WRC 23 agreed to open up the 6 GHz band for future high-speed mobile communications (instead of for unlicensed WiFi). The 6 GHz band (6.425-7.125 GHz) – was identified for mobile in every ITU Region – EMEA, the Americas and the Asia Pacific. Countries representing more than 60% of the world’s population asked to be included in the identification of this band for licensed mobile at WRC-23. The 6 GHz spectrum is now the harmonized home for the expansion of mobile capacity for 5G-Advanced and beyond.
