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.

Abstract: A group of sensor devices is connected to the power line and configured for collecting power usage information and enabling power management to reduce the carbon foot print of the home, as well as to provide local area networking. In one embodiment of the invention, the devices include an intelligent master sensor and its sub-sets, such as a communication and power management sensor and a power control switch sensor. The master device is configured to collect, compile, and communicate the collected data via the web or other communication medium to the outside world. The master device also receives and distributes control instructions that are used to control the power usage via the associated switches in the home or office. The sensors are used in the home or office environment to provide integrated sensing and control of home power usage and power management, while establishing a LAN having communication capability, including streaming media delivery capability.
