Three years ago, Wi-Fi 6 technology entered the market, providing faster speeds, lower latency and improved security for many homes. Since then, a series of technological developments have made the Wi-Fi experience better. In order to solve the congestion problem of 2.4Ghz and 5.8Gh, in 2020, the Wi-Fi Alliance announced the expansion of Wi-Fi 6 from the 2.4GHz and 5Ghz frequency bands to 6Ghz , namely Wi-Fi6E, what are the main improvements of Wi-Fi6E compared to Wi-Fi6? Follow in my footsteps and let's go see it together.
Wi-Fi6E has one more E than Wi-Fi6. E stands for "Extended", which means extension and strengthening. It can be seen that WiFi6E is an enhanced version of WiFi6. We can see from the following figure that Wifi 6E has new frequency:6Ghz which is added beside 2.4Ghz and 5Ghz.
The 6GHz band enables higher concurrency, lower latency, and higher bandwidth, with an operating frequency range of 5925 MHz to 7125 MHz (including 7 160MHz channels, 14 80MHz channels, 29 40MHz channels, 60 20MHz channels, a total of 110 Compared with 45 channels of 5Ghz and 4 channels of 2.4Ghz, the capacity is larger and the throughput is greatly improved.
Wi-Fi6E brings a more efficient way to pack data, because it transmits on one signal, thus quadrupling the data rate for a given channel, thereby increasing network speed, the ideal peak rate for Wi-Fi6E Can reach 3.6Gbps.
Each version of the Wi-Fi standard has improved the battery life of network devices. Since each version brings faster speeds, data transfers are faster and the device doesn't consume as much energy. And, Wi-Fi 6/E will further improve battery saving with a feature called Target Wake Time, it has a feature called Target Wake Time, this feature puts the device into a low power mode, these short sleep times also increase the battery life.
Even though Wi-Fi 6E has improved a lot compared to Wi-Fi 6/5 in various aspects, due to the price of the router and the limitation of network bandwidth, it will take some time for the large-scale popularization of Wi-Fi 6E devices. The mainstream transmission protocol is still Wi-Fi 5 (802.11ac). While major terminal manufacturers are still promoting Wi-Fi 6/5, Oflycomm quietly launched its first Wi-Fi 6E wireless module model O2066PM in early 2022, using Qualcomm's QCA2066(QCA206X) , the new O2066PM is designed in the form of M.2 2230. In addition to supporting Wi-Fi 6E, it also supports Bluetooth 5.2. It is equipped with 2x2 antennas, 2*2 TX/RX streams, supports MU-MIMO, and adds support for the 6GHz frequency band. Support, wireless transmission speed up to 3000Mbps.
