Table 3 Signal Strength Figure of Merit
Table 4 Signal Quality Figure of Merit
Getting any Signal Strength reading at all indicates that packets are being received from the
CCU. The higher the signal strength and signal quality indicators, the lower the packet error
rate and the higher the fade margin for the EUM3005. The goal should be a signal strength of
5 or higher and a signal quality of 4 or 5. Regardless of the levels, the EUM3005 should be
aligned so that the indicators are the highest possible for the given site.
