Table 8 Signal Strength Figure of Merit
Table 9 Signal Quality Figure of Merit
Getting any Signal Strength reading at all indicates that packets are being received from the
Base Station. The higher the signal strength and signal quality indicators, the lower the packet
error rate and the higher the fade margin for the MMT9000. The goal should be a signal
strength of 5 or higher and a signal quality of 4 or 5. Regardless of the levels, the MMT9000
should be aligned so that the indicators are the highest possible for the given site.
