Important information

Legal Disclaimer

Maximum wireless transmission rates are the physical rates derived from IEEE Standard 802.11 specifications. Range and coverage specifications are based upon test results under normal usage conditions. Actual wireless transmission rate and wireless coverage 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. 2. Claims about 802.11ax Wi-Fi technology are based on comparisons of the expected maximum theoretical data rates for one spatial stream using 802.11ax at 160 MHz (1201 Mbps) as opposed to one spatial stream using 802.11ac at 80 MHz (433 Mbps) as documented in IEEE 802.11ax draft 3.0 spec and IEEE 802.11-2016 wireless standard specifications, and require the use of similarly configured 802.11ax wireless network routers. Use of 802.11ax Wi-Fi standard requires clients to also support the 802.11ax Wi-Fi standard. 3. Use of MU-MIMO, DL/UL OFDMA, TWT, WPA3 and 1024QAM requires clients to also support those functions. 4. Capacity refers to overall average throughput. This amendment defines standardized modifications to both the IEEE 802.11 physical layers (PHY) and the IEEE 802.11 Medium Access Control layer (MAC) that enable at least one mode of operation capable of supporting at least four times improvement in the average throughput per station (measured at the MAC data service access point) in a dense deployment scenario, while maintaining or improving the power efficiency per station. 5.Saving clients' battery power requires clients to also support the 802.11ax Wi-Fi standard. Actual power reduction may vary as a result of network conditions, client limitations, and environmental factors. 6. This router may not support all the mandatory features as ratified in Draft 3.0 of IEEE 802.11AX specification.
