Hello Mi Fan's!!!
WiFi 6 is still in the early stage of a large-scale blowout. At present, only a few new routers or terminal products support the latest WiFi 6 protocol. However, technology is changing with each passing day, and the next generation of WiFi 7 is already on the road. It is reported that the theoretical maximum transmission rate of WiFi 7 can reach 30Gbps, which is three times the maximum rate of 9.6Gbps for WiFi 6.
Compared with the current mainstream WiFi 5 (802.11 ac) wireless transmission protocol, the new WiFi 6 (802.11 ax) is not only 40% faster but also consumes less power. Routers using the WiFi 6 protocol can support more devices to connect at the same time. Moreover, they support the latest WP3 security protocol. Even for hackers, it’s difficult to crack.
WiFi 7 still has the necessity of its existence. The 802.11 standard is under development. We know that the MU-MIMO technology introduced by WiFi 6 supports up to 8 data streams to work at the same time. In this sense, WiFi 7 will introduce CMU-MIMO technology.It supports up to 16 data streams, 8 lanes to 16 lanes, proper interstellar highway, etc. Apart from the traditional 2.4GHz and 5GHz bands, WiFi 7 will also support the 6GHz frequency band.
All three frequency bands can work simultaneously. Finally, WiFi 6 (802.11 ax) currently uses the 1024-QAM signal modulation method. And WiFi 7 using the 802.11 be standard will be upgraded to a 4096-QAM signal modulation method. It is simple and rough to expand the data transmission capacity. So it is not surprising this technology will reach a speed of 30Gbps.
