Figure 180: Alignment Tool tab of SM, example for an unacceptable link
Proper alignment must achieve all of the following indications for an acceptable link between the
modules:
• power level of not less than -75dBm
• jitter value between 0 and 4
• uplink and downlink efficiency greater than 90%, except as described under Comparing
Efficiency in 1X Operation to Efficiency in 2X Operation on Page 133.
IMPORTANT!
If any of these values is not achieved, a link can be established but will manifest
occasional problems.
The relationship between Air Delay and link quality is described under AP-SM Links on Page 99.
