The Signal Quality bar area graphically represents the Signal-to-
Noise Ratio (SNR) of the downlink access code channel (ACC)
received by the Modem. Again, the SNR is represented by a group
of colored bars. The higher the pile of bars goes, the better the SNR
of the signal. The color of the bars also gives an indication of the
quality of the signal. Green lines indicate a high SNR. Orange lines
indicate a moderate SNR while red lines indicate a low SNR.
To increase the strength and quality of the signal, change the
location of the Ripwave Modem. Try moving it closer to a window,
to a higher location, away from other wireless devices (microwave
ovens, cordless phones), and away from metal objects (shelves, file
cabinets). As the Ripwave Modem is repositioned, observe the
Signal Strength and Signal Quality bars. Position the Modem for
maximum signal strength and quality.
The History graphs plot the change in signal strength and signal
quality over time. The graphs cover the last minute and are updated
every second. Read the graphs from right to left. The right side of
the graph represents the most recent status of your Modem.
At the bottom of the Connection Status screen, are four parameters.
These parameters are BTS ID, Network ID, Active SW Version,
and Standby SW Version. The BTS ID and Network ID indicate
the BTS to which the Modem is currently synchronized and the
network in which the Modem is operating. Active SW Version and
Standby SW Version indicate the version number of the software
currently loaded in the “active side” and “standby side” of the
Modem’s flash memory.
