What is band steering and how does it work?
Band steering balances the load in your wireless network, which ensures fast and stable connections for all of the wireless devices in the home network.
Modern routers or wireless repeaters, 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. Wireless devices that support both frequency bands are allowed to decide which frequency to use for a connection. However, wireless devices do not always make the optimal choice. With band steering technology, routers and repeaters can determine which frequency band is more suitable for individual wireless devices and automatically steer them to the more suitable one.
Low frequencies can penetrate obstacles such as walls, metallic objects, or objects containing water more easily, which is why the 2.4 GHz frequency band has a greater range. The 5 GHz frequency band, on the other hand, offers more speed near a wireless router since a wider frequency spectrum can be used there, allowing more data to be transmitted in the same amount of time.
With band steering, the FRITZ!Box improves the wireless range of devices in the 5 GHz frequency band by checking whether their signal strength reaches a specific threshold. If the value for a device falls below this value, then it is on the edge of the range. The FRITZ!Box then steers the device to the 2.4 GHz frequency band because this band has a greater range.
The FRITZ!Box uses band steering to avoid congestion in the 2.4 GHz frequency band by steering wireless devices to the 5 GHz frequency band. For this, it first deregisters all devices from the 2.4 GHz frequency band and briefly blocks them so that wireless devices capable of 5 GHz connect to the 5 GHz frequency band. If registration of a wireless device in the 5 GHz frequency band fails, it is then permitted to use the 2.4 GHz frequency band shortly afterwards.
The FRITZ! device learns the device's properties when it registers for the first time. If it turns out that the wireless device supports both frequency bands, starting with the next time it registers, it will be steered into the more suitable frequency band depending on the situation. If the FRITZ!Box is restarted, it must relearn the properties of the individual wireless devices. Band steering also also effects the wireless devices using wireless guest access so that your guests also have stable and fast wireless connections.
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. For band steering, both frequency bands must have identical wireless network names (SSIDs). If you were using different wireless network names, give both of the frequency bands the same wireless network name and then enable the option "To improve data transmission, a dual-band wireless device can be set to switch between the 2.4 and the 5-GHz frequency band automatically" in the FRITZ!Box user interface under "Wireless > Radio Channel" in the section "Radio Channel Settings > Additional settings". Band steering is enabled in the factory settings.
