Which three factors impact indoor WLAN coverage areas?

Indoor WLAN coverageis influenced by multiple RF and physical parameters that determine how effectively a signal propagates and maintains connectivity quality.

According toRUCKUS One Online Help – RF Design FundamentalsandRUCKUS AI Documentation – Coverage Optimization, the three most impactful factors are:

AP Transmit Power (A):Directly affects signal reach; excessive power can cause co-channel interference, while low power results in coverage holes.

AP Orientation (C):Affects signal radiation direction—wall-mounted, ceiling-mounted, or tilted deployments impact pattern uniformity and coverage overlap.

Antenna Pattern (D):Defines gain and directional behavior; omnidirectional antennas provide uniform coverage, while directional models concentrate energy for targeted areas.

Antenna diversityandspatial multiplexingimprove throughput and reliability, but do not primarily determine raw coverage boundaries. “Earth bulge” is irrelevant for indoor deployments.
