6.3 Frequency Settings

Use this screen to have the WiMAX Device to scan one or more specific radio frequencies (given by

your WiMAX service provider) to find available connections to base stations.

Mode Select Select how the BM2022w connects to the base station.

• Auto Connect Mode - The device connects automatically to the first base

station in range.

• Network Search Mode - The device scans for available base stations then

connects to the best one it can.

BSID This displays the MAC address of a base station within range of the BM2022w.

Preamble ID The preamble ID is the index identifier in the header of the base station’s

broadcast messages. In the beginning of a mobile stations’s network entry

process, it searches for the preamble and uses it to additional channel

information.

The preamble ID is used to synchronize the upstream and downstream

transmission timing with the base station.

Frequency

(MHz)

This field displays the radio frequency of the BM2022w’s connection to the base

station.

Bandwidth

(MHz)

This field displays the bandwidth of the base station in megahertz (MHz).

RSSI (dBm) This field displays the Received Signal Strength Indication (RSSI), which is an

overall measurement of radio signal strength. A higher RSSI level indicates a

stronger signal.

CINR (dB) R3/

This field displays the average Carrier to Interference plus Noise Ratio for the

current connection. This value is an indication of overall radio signal quality,

where a higher value means a better quality signal.

Search Click this to have the BM2022w scan for base stations.
