(1) Perform a test with a mobile phone or data card Check below:
- A weak input signal leads to the low output power. Need to change the direction
of outdoor antenna or its installation position or replace outdoor antenna with
higher gain antenna to increase input signal power level.
- Check whether it is necessary to add more Indoor antennas’ sine barriers to
block the signal penetration, and check whether the repeater’s power is enough.
Install more Indoor antennas or replace with a repeater of higher power level.
