Summary:

"The IEEE 802.11 Working Group develops the standards for the wireless local area network, referred to in the industry as Wi-Fi. Many of the new 802.11 standards focus on improving the data throughput of the Wi-Fi network. Currently the 802.11 working group is developing a new Wi-Fi standard (802.11ba) for a wake-up radio (WUR) which allows the primary Wi-Fi radio to go into a deep sleep mode. This 802.11ba WUR is expected to expand the market for Wi-Fi to enable it to operate using small coin cell batteries."-- Provided by publisher.
