Get Your Home Ready for WiFi 6 (802.11ax)

The growing number of connected personal and IoT devices has led to an overall increase in network density that is pushing the limits of the current Wi-Fi standard. The latest 802.11ax standard provides future-proof technologies, higher network efficiency, faster Wi-Fi speeds, greater coverage and improved battery life for connected devices, providing a significantly better networking experience for users.
*It requires 802.11ax-compatible devices to enjoy the benefits brought by 802.11ax WiFi standard.

Next-Gen WiFi Speed

RT-AX56U is a 2x2 dual-band Wi-Fi router that provides 80MHz bandwidth and 1024-QAM for dramatically faster wireless connections. With a total networking speed of about 1800Mbps — 574Mbps on the 2.4GHz band and 1201Mbps on the 5GHz band — RT-AX56U is 1.5X faster than 802.11ac 2x2 dual-band routers.

    Built for Multi-device Households

    With a revolutionary combination of OFDMA and MU-MIMO technology, 802.11ax technology provides up to 4X greater network capacity and efficiency in traffic-dense environments. Previous-generation 802.11ac Wi-Fi can only handle one device at a time on each network channel, which is an inefficient use of available bandwidth. OFDMA support in the 802.11ax Wi-Fi standard divides each channel into small sub-channels, allowing signals from multiple devices* to be bundled together and transmitted simultaneously, reducing latency for a smoother, more responsive Wi-Fi experience.

    Better Battery Life for Your Devices

    Target Wake Time (TWT) allows RT-AX56U to schedule designated intervals for devices to transmit data. This allows them to sleep when there is no need to wait for a router signal, reducing power consumption by up to 7X for significantly improved battery life*.

  • Better Coverage

    WiFi that Goes Farther

    With the latest 802.11ax WiFi standard featuring OFDMA technology, RT-AX56U provides increased WiFi signal range and better coverage by dividing each channel into smaller sub-channels. These sub-channels have a smaller bandwidth that enables them to travel up to 80% farther1, resulting in a better WiFi connection throughout your home*.

Disclaimers:

  • 1 The data refers to uplink OFDMA
  • 2 ac data refers to: 40MHz / 256QAM on 2.4GHz band and 80MHz / 256QAM on 5GHz band. ax data refers to: 40MHz / 1024QAM on 2.4GHz band and 80MHz / 1024QAM on 5GHz band
  • * To benefit from 802.11ax features, the Wi-Fi client needs to be 802.11ax capable.
  • ** Actual data throughput and WiFi coverage will vary from network conditions and environmental factors, including the volume of network traffic, building material and construction, and network overhead, result in lower actual data throughput and wireless coverage.
  • *** Quoted network speeds and bandwidth based on current IEEE 802.11ax specifications. Actual performance may be affected by network and service provider factors, interface type, and other conditions. Connected devices must be 802.11ax-compatible for best results.
