What is band steering and how does it work?

Band steering balances the load in your wireless network and ensures that your router provides stable and fast connections.

Modern routers or wireless access points, such as the FRITZ!Box 7590 or FRITZ!WLAN Repeater 1750E, make the 2.4 GHz and 5 GHz frequency band available at the same time. However, wireless devices that are capable of using both frequency bands do not always select the optimal frequency band.

Band steering technology enables routers or access points to recognize which frequency band is more suitable for a particular wireless device and automatically steer it to the more suitable frequency band.

Since it is easier for low frequencies to penetrate obstacles such as walls, metallic objects, or objects containing water, the 2.4 GHz frequency band offers a greater range than the 5 GHz frequency band. By contrast, the 5 GHz frequency band offers a faster connection in the vicinity of your wireless router because its frequency spectrum is wider than that of the 2.4 GHz frequency band. This allows more data to be transmitted in the same amount of time.

To improve the range of wireless devices in the 5 GHz frequency band, the FRITZ!Box checks whether the signal strength reaches a specific threshold. If it falls below this value, this means that the wireless device is on the edge of the range and the FRITZ!Box initiates a switch to the 2.4 GHz frequency band that has a greater range.

To avoid very heavy load in the 2.4 GHz frequency band, the FRITZ!Box checks which wireless devices can also connect to the 5 GHz frequency band. To do so, it deregisters all devices in the 2.4 GHz frequency band and briefly prohibits them from using the 2.4 GHz band. If a wireless device cannot register with the 5 GHz frequency band, the router allows the wireless device to re-register with the 2.4 GHz frequency band.

The FRITZ!Box supports band steering starting with FRITZ!OS 6.80; FRITZ!WLAN Repeater and FRITZ!Powerline adapters support it starting with FRITZ!OS 6.90. In order to enable band steering, both frequency bands must have identical wireless network names (SSIDs). The first time a wireless device is registered, the FRITZ! device learns the device's properties. If the wireless device supports both frequency bands, then it is steered to the most suitable frequency band the next time it is registered. If the FRITZ!Box , repeater, or FRITZ!Powerline is restarted, then it must relearn the properties of the individual wireless devices. Band steering also effects the wireless devices using wireless guest access.
