5.16.1.4 Radio Features
AP Density
This option allows you to determine the signal strength at which the 7545 radio will begin
searching for a new Access Point (AP): High, Medium or Low. If, for example, this option is
set to High, the radio will begin searching for a new Access Point while still at a fairly strong
signal strength. Setting AP Density to Low will cause the radio to wait until the signal
strength is significantly low before attempting to connect to another Access Point.
Depending on your site configuration—for example, the shelving, the Access Point cover-
age, etc.—a higher setting may improve through-put, increase and maintain signal strength,
and reduce missed transmissions.
Radio Power Management
When this option is enabled, access points that support it will use Radio Power Management
guidelines to control the client (7545) radio. Access points determine how often the 7545
radio enters sleep mode when no activity is detected to reduce power consumption on the
client side. Another benefit is that when Radio Power Management is enabled, even when
no activity is detected, the access point does not disassociate the 7545 (client).
