Chapter 21 The Status Screen Table 113 Status (continued) LABEL DESCRIPTION Cell ID A base station's coverage area can be divided into multiple cells. This field shows the identification number of the cell in which the WiMAX Device is connected. Frequency This field displays the radio frequency of the WiMAX Device's wireless connection to a base station. MAC address This field displays the Media Access Control address of the WiMAX Device. Every network device has a unique MAC address which identifies it across the network. WiMAX State This field displays the status of the WiMAX Device's current connection. Bandwidth CINR mean CINR deviation RSSI • INIT: the WiMAX Device is starting up. • DL_SYN: The WiMAX Device is unable to connect to a base station. • RANGING: the WiMAX Device and the base station are transmitting and receiving information about the distance between them. Ranging allows the WiMAX Device to use a lower transmission power level when communicating with a nearby base station, and a higher transmission power level when communicating with a distant base station. • CAP_NEGO: the WiMAX Device and the base station are exchanging information about their capabilities. • AUTH: the WiMAX Device and the base station are exchanging security information. • REGIST: the WiMAX Device is registering with a RADIUS server. • OPERATIONAL: the WiMAX Device has successfully registered with the base station. Traffic can now flow between the WiMAX Device and the base station. • IDLE: the WiMAX Device is in power saving mode, but can connect when a base station alerts it that there is traffic waiting. This field shows the size of the bandwidth step the WiMAX Device uses to connect to a base station in megahertz (MHz). This field shows the average Carrier to Interference plus Noise Ratio of the current connection. This value is an indication of overall radio signal quality. A higher value indicates a higher signal quality, and a lower value indicates a lower signal quality. This field shows the amount of change in the CINR level. This value is an indication of radio signal stability. A lower number indicates a more stable signal, and a higher number indicates a less stable signal. This field shows the Received Signal Strength Indication. This value is a measurement of overall radio signal strength. A higher RSSI level indicates a stronger signal, and a lower RSSI level indicates a weaker signal. UL Data Rate DL Data Rate PER A strong signal does not necessarily indicate a good signal: a strong signal may have a low signal-to-noise ratio (SNR). This field shows the number of data packets uploaded from the WiMAX Device to the base station each second. This field shows the number of data packets downloaded to the WiMAX Device from the base station each second. This field shows the Packet Error Rate. The PER is the percentage of data packets transmitted across the network but not successfully received. User's Guide 255
