*Maximum wireless transmission rates are the physical rates derived from IEEE Standard 802.11 specications. Range, coverage, and maximum quantity of connected devices are based on test results under normal usage conditions. Actual wireless data throughput. wireless coverage, and quantity of connected devices are not guaranteed and will 
vary as a result of 1) environmental factors, including building materials, physical objects, and obstacles, 2) network conditions, including local interference, volume and density of trac, product location, network complexity, and network overhead, and 3) client limitations, including rated performance, location, connection quality, and client condition.
Use of MU-MIMO requires clients to also support MU-MIMO.
