Band Steering
Band steering is a technology that automatically directs
Wi-Fi devices to the best available frequency band, either 2.4 GHz or 5 GHz, to
improve Wi-Fi performance. It's used in dual-band routers and access points.
Band steering is beneficial in environments with
many devices and users, like apartment buildings, where it can help balance the
load and optimize the user experience. It does this by:
Detecting dual-band capability
Band steering can detect if a device is dual-band capable
and push it to connect to the less congested 5 GHz network.
Blocking 2.4 GHz attempts
Band steering can block a device's attempts to associate
with the 2.4 GHz network.
Considering device characteristics
Band steering takes into account the technical
characteristics of the device and its distance from the access point.
The 5 GHz band is generally faster and performs better than the 2.4 GHz band but has a shorter signal reach. This
means multiple access points may be needed to provide adequate coverage in
a home.
This is covered in Network+.
