better multi-user access and better power management for IoT devices

WiFi 6 is a step up from its predecessor, offering higher connection speeds and efficiency. We currently have its 6E WiFi variant, which brought us the 6 GHz band and is present in high-end routers. However, at CES 2022, the WiFi Alliance announced new features in this standard, billed as a “second version”.

With ‘WiFi 6 Release 2’, it is proposed to achieve greater energy efficiency of connected devices at home and better performance under conditions of high data and user traffic.

Further improvements in energy efficiency and multi-user data download

All the improvements are compatible for the three bands that currently exist, namely 2.4 GHz, 5 GHz and the new 6 GHz. This new protocol, in addition to offering all the known functionalities of WiFi 6, adds support for uplinks for user inputs and multi-outputs (MU-MIMO). This ensures higher connection speeds in high data and device traffic situations, offering, according to the WiFi Alliance, improvements in streaming, video conferencing and faster downloads.

Another of the strengths of this new version are the advancements in energy management in smart home devices, offering improvements in standby modes and low consumption. To this end, Target On Time (TWT) functions, extended standby mode and energy savings through multi-user dynamic spatial multiplexing (SMPS) have been implemented, enabling energy optimization in multiple devices. using the battery.

According to the WiFi Alliance, these improvements will benefit both the connected home and the concept of smart cities and industrial environments.

All of these features are nothing more than a response to the demand for better connections due to increased data traffic and workload in local networks. In addition, developers will have more leeway to improve the battery life of smart home devices, be it cameras, speakers or sensors, among others.
