TPC (Transmit Power
Control) Back-off
The AP device transmits maximum output power, as per the selected frequency and country
(regulatory domain). With TPC Back-off, you can adjust the output power of the AP device
to a lower level, in order to reduce the interference with the neighboring devices or to use a
higher gain antenna without violating the maximum radiated output power allowed for your
regulatory domain.
By default, it is set to 0 dBm. To configure, enter a value ranging from 0 to 25 dBm in the
TPC Back-off box.
: TPC Back-off range (0-25 dBm) varies for different cell sizes (Large, Medium, Small,
Micro and Mini).
Cell Size Specifies the parameter that enables you to control the coverage area of the AP device in
different types of deployment scenarios. For instance, usage of small cell size in dense device
deployment, minimizes the interference caused by one device on another.
Cell sizes supported by the AP device are Large, Medium, Small, Micro and Mini. By default,
it is Large. To configure, select the Cell Size from the drop down menu.
Cell Size Functionality
It is classified for different VAP types (See Virtual Access Point (VAP), for details),
defining the relation between transmit power, receive sensitivity and CCA threshold
associated with different Cell Sizes.
Type Description
AP Cell Size Functionality When the cell size is set to Large, the transmit power and
receive sensitivity are high. When the Cell Size is set from
Large to Micro, Mini, Small or Medium, the transmit power
is reduced.
Data tabulated below explains the AP Cell Size Functionality
for different Cell Sizes.
* Maximum transmit power depends on the selected frequency
domain and type of radio card.
