Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Range, coverage, and the maximum number of connected devices are based on test results under normal usage conditions. Actual wireless data throughput, wireless coverage, and number 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 traffic, product location, network complexity, and network overhead, and 3) client limitations, including rated performance, location, connection quality, and client condition.
