TPC (Transmit Power Control) Back-off: By default, the device transmits maximum output power, as per the
selected frequency and country (regulatory domain). However, with TPC parameter, you can adjust the output
power of the device to a lower level in order to reduce 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, the value is set to 0 dBm. To configure, enter a value ranging from 0 to 25 dBm in the TPC Back-off
box.
•
Cell Size: This parameter enables the user to control the coverage area of the device in different types of
deployment scenario. 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, Cell Size taken is
Large. To configure, select the Cell Size from the drop down menu.
Cell Size functionality is classified for different VAP types (See
relation between transmit power, receive sensitivity and CCA threshold associated with different Cell Sizes.
— 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. Tabulated below are the
details that explain the AP Cell Size Functionality for different Cell Sizes.

— WDS Cell Size Functionality
For a WDS link (See
Mini, Small or Medium, the transmit power is retained to the maximum value. Tabulated below are the
details that explain the WDS Cell Size Functionality for different cell sizes.
