Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage are not guaranteed and will vary as a result of network conditions, client limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and client location.

Use of Wi-Fi 6 (802.11ax), and features including OFDMA, 1024-QAM, MU-MIMO, and HE160 requires clients to also support the corresponding features. The 160 MHz bandwidth may be unavailable in the 5 GHz band in some regions/countries due to regulatory restrictions. The double channel width refers to 160 MHz compared to 80 MHz for general WiFi 6 devices.

§Smart Roaming is designed for devices that support the 802.11k/v standard.

The maximum capacity is the maximum number of signals that can be connected under ideal conditions, and the specific situation varies with the location of the RE, the type of connected equipment, etc.

*The product may not be compatible with routers or gateways with firmware that has been altered, based on open source programs, or is non-standard or outdated.


Actual network speed may be limited by the rate of the product's Ethernet WAN or LAN port, the rate supported by the network cable, Internet service provider factors and other environmental conditions.
