7.3 Radio Optimization
7.3.1 Overview
Application Scenarios
Generally, wireless networks are widely applied to the following two scenarios:
Ordinary scenario
For areas that demand wide WiFi coverage, such as offices, public buildings, schools, warehouses and
hospitals.
High density scenario
For large crowded areas, such as:
− Conference halls, theaters, exhibition and banquet halls
− Indoor and open stadiums
− Classrooms at colleges and universities
− Airports and railway stations
Radio Optimization Parameters
To address the demands of both coverage-oriented and high-density scenarios, the AP provides a series of
parameters for radio optimization, facilitating our customers to create qualified wireless network service.
Prioritize 5 GHz
Although the 2.4 GHz band is more widely used than the 5 GHz band in actual wireless networks application,
channels and signals on 2.4 GHz suffer more serious congestion and interference since there are only 3
non-overlapped communication channels on this band. The 5 GHz band could provide more non-overlapped
communication channels. The quantity could reach more than 20 in some countries.
With the evolvement of the wireless networks, wireless clients that support both the 2.4 GHz and 5 GHz are
more popular. However, by default, such dual-band wireless clients choose the 2.4 GHz to connect, resulting in
even worse congestion of the 2.4 GHz band and the waste of the 5 GHz band.
The prioritize 5 GHz functions enables such dual-band wireless clients to connect the 5 GHz band on network
initialization if the 5 GHz signal strength the AP received reaches or exceeds the 5 GHz threshold so as to
improve the utilization of the 5 GHz band, reduce the load and interference on the 2.4 GHz band, thus
bettering user experience.
