Use the Radio page to configure the device radio interface parameters. This post will focus on the Power Control attributes.
Power Control

Attribute |
Meaning |
|
|
Max Tx Power |
Auto: The Access Point can control, using ATPC (Automatic Transmit Power Control), the TX power of the SM up to the maximum capability of the SM’s transmitter (based on regulatory limits). Manual: The Access Point can control the TX power of the SM up to the value configured in the Transmitter Output Power field below. |
|
|
Transmitter Output Power |
When Manual is selected, the SM will not transmit higher than the configured value in the field. Determines the maximum output power of the transmitter. The actual output power may be lower due to Automatic Transmit Power Control (ATPC), where the AP instructs the SM to lower its power to meet the SM target Receive Level configured on the AP. |
|
|
Antenna Gain |
This value represents the amount of gain introduced by the unit’s internal antenna. This parameter is read-only for Integrated radios. |
|
|
Network Entry RSSI Threshold |
Set this parameter to the minimum Received Signal Strength Indicator (RSSI) at the SM required for the SM to attempt registration to an AP. For example, if the AP RSSI Threshold is set to -80 dBm, and the SM is receiving the AP signal at -85 dBm (RSSI = -85 dBm), the SM will not attempt to register to the AP. |
|
|
Network Entry SNR Threshold |
Set this parameter to the minimum Signal-to-Noise Ratio (SNR) at the SM required for the SM to attempt registration to an AP. For example, if the AP SNR Threshold is set to 30 dB and the SM is calculating its DL SNR as 25 dB, the SM will not attempt to register to the AP. |
|
|
Uplink Antenna Selection |
Uplink Antenna Selection specifies the antenna to be used in the uplink. This parameter is specific to SMs registered to ePMP 2000 APs configured with an optional Smart Antenna. Auto: The AP decides which antenna to use (sector or Smart Antenna) for uplink communications based on internal quality metrics. Forced Sector Antenna: The AP uses the Sector Antenna for uplink communications with SMs configured with this option Forced Smart Antenna: The AP uses the smart antenna for uplink communications with SMs configured with this option
