Why is the signal strength that a STA receives from an AP weak

The possible causes are:
- The transmit power of the AP is low. In this case, increase the transmit power.

- The antenna system of the AP (indoor DAS AP) is not properly deployed.
1. The output power on antenna interfaces is low because the AP connects to excess antennas. Or the feeder lines are too long.
2. The passive devices (combiner, splitter, and coupler) do not comply with design principles or specifications or are not properly connected.
3. The passive devices have unloaded interfaces.

- The STA is far away from the AP's antennas, so the signal loss is large.

- Signals are blocked by a beam, post, concrete wall, metal door, or other obstacles between the STA and antennas. In this case, change the antenna installation positions.
