Claim:
1. A wireless hotspot sensor system comprising: a plurality of wireless hotspot sensors distributed over an area corresponding to a local area network (LAN); wherein each of the wireless hotspot sensors is enabled to transmit a radio frequency output signal in at least an axial direction outward from the corresponding wireless hotspot sensor, wherein the corresponding radio frequency output signal has a directional power lobe defined in the axial direction, wherein the directional power lobe has an adjustable radio frequency output power level; wherein each of the wireless hotspot sensors includes a switch for adjusting the radio frequency output power level of the corresponding directional power lobe, and a power level indicator for monitoring the radio frequency output power level of the corresponding directional power lobe; wherein each of the wireless hotspot sensors are interconnected using a power line communication (PLC) network within the LAN; wherein the wireless hotspot sensors are spatially separated from each other, and are enabled to simultaneously transmit a common output signal over a common radio frequency spectrum to provide wireless coverage in the LAN; wherein each of the wireless hotspot sensors is enabled to adjust the corresponding radio frequency output power level responsive to activation of the corresponding switch; wherein each of the wireless hotspot sensors is further configured to indicate the current corresponding radio frequency output power level through the corresponding power level indicator; and wherein the radio frequency output power level of each of the wireless hotspot sensors is enabled to provide effective wireless area coverage within the LAN while eliminating or reducing wireless interference and fading due to a first directional power lobe of a first wireless hotspot sensor of the wireless hotspot sensors interfering with a second directional power lobe of a second wireless hotspot sensor of the wireless hotspot sensors, transmitting on the same radio frequency on the LAN.
