Abstract
A method and a system for providing wireless communication facility with low interference between multiple wireless devices providing hotspot wireless coverage within a local area of an integrated enterprise or integrated home environment is disclosed. The sensor devices implementing hotspots are connected to a local area network (LAN) based on power line communication (PLC) and enabled with wireless power output control capability, allowing the coverage of area of each sensor device to be adjusted. The power output control is by a switch which allows the power output to be increased and decreased depending on coverage required and the output of the nearest hotspot. The power output level is indicated on the sensor by LEDs to enable resetting and adjustment. The use of power control and elimination of coverage overlap allow multiple hotspots to be used for achieving good connectivity while reducing interferences and noise within hotspots during connection and use.
