ePMP: How to view a radio’s wireless interface

Use the Wireless page to reference key information about the radio’s wireless interface.

Attribute

Meaning

Registered AP SSID

SSID of the AP to which the SM is registered.

Registered AP MAC address

Wireless MAC address of the AP to which the SM is registered.

Distance from AP

The distance from the AP, determined by radio signal propagation delay.

Operating Frequency

The current frequency at which the SM is transmitting and receiving.

Operating Channel Bandwidth

The current channel size at which the SM is transmitting and receiving.

Downlink RSSI

The Received Signal Strength Indicator, which is a measurement of the power level being received by the SM’s antenna.

Downlink SNR

The Signal to Noise Ratio, which is an expression of the carrier signal quality with respect to signal noise.

Transmitter Output Power

The current power level at which the SM is transmitting.

Uplink MCS

Modulation and Coding Scheme – indicates the modulation mode used for the radio uplink, based on radio conditions (MCS 1-7, 9-15).

Downlink MCS

Modulation and Coding Scheme – indicates the modulation mode used for the radio downlink, based on radio conditions (MCS 1-7, 9-15).

Power Control Mode from AP

Open Loop: In this mode, the SM will not receive any power change information in the Group Poll Frame. SM calculates the UL transmit power based on path loss calculations only.

Closed Loop: In closed loop UL power control, Subscriber Module will get the AP actual transmit power of beacon frame and SM Target Received Power Level in the beacon. Based on these two values, SM calculates the path loss. Based on path loss and TRL values it calculates it’s transmit power such that the signal from SM arrives at AP at the configured target level. Path loss calculation will be updated by SM every time there is a change in values of AP actual TX power or TRL in the Beacon.

Forced Sector Antenna

When an ePMP 2000 AP is deployed with a Sector Antenna and a Smart Antenna, this parameter forces the AP to use only Sector Antenna for all Subscriber Modules.

Ethernet Interface

Up: The radio (LAN) interface is functioning properly.

Down:  The radio (LAN) interface has encountered an error and is not servicing traffic.

Wireless Interface

Up: The radio (WAN) interface is functioning properly.

Down: The radio (WAN) interface has encountered an error and is not servicing traffic.

Country

The current code the SM is operating under.

Time since last scan

Amount of time elapsed since the last scan was completed by the SM for available APs.

Registration Status

The current registration status of the SM.

Available APs

The Available AP list may be referenced to view which APs are available for SM network entry, and also to view the status of the current AP to SM radio link.

Add as Preferred

Click the AddBTN.png button to add the AP to the Preferred AP List under Configuration->Radio.

SSID

The SSID of the visible AP.

MAC Address

The MAC address of the visible AP.

Frequency Carrier (MHz)

The current operating frequency of the visible AP.

Channel Bandwidth

The current operating channel bandwidth of the visible AP.

RSSI (dBm)

The current measured Received Signal Strength Indicator at the AP.

SNR (dB)

The current measured Signal-to-Noise Ratio of the SM to AP link.

Registration State

The indication of the result of the SM’s network entry attempt:

Successful:  SM registration is successful

FailedOut of Range:  The SM is out of the AP’s configured maximum range (Max Range parameter)

FailedCapacity limit reached at AP:  The AP is no longer allowing SM network entry due to capacity reached

Failed:  No Allocation on AP:  The SM to AP handshaking failed due to a misconfigured pre-shared key between the SM and AP

Failed:  SW Version Incompatibility: The version of software resident on the AP is older than the software version on the SM

Failed:  PTP Mode:  ACL Policy: The AP is configured with PTP Access set to MAC Limited and the SM’s MAC address is not configured in the AP’s PTP MAC Address field

Failed: Other:  The AP does not have the required available memory to allow network entry

Session Time (hh:mm:ss)

This timer indicates the time elapsed since the SM registered to the AP.

Wireless Security

This field indicates the security state of the AP to SM link.

Meets Reg Criteria

Yes: The scanned AP meets the Network Entry criteria defined by the internal Network Algorithm.

No: The scanned AP does not meet the Network Entry criteria defined by the internal Network Algorithm.
