1. A wireless mote network comprising:
a plurality of motes, wherein each of the plurality of motes includes:
a processing unit in communication with a communications device, wherein the communications device is configured to emit an identification signal that includes an identification number of the mote and a time stamp indicating the time the signal was sent in response to the mote receiving an inquiry signal;
a sensor configured to monitor an environmental condition in an area around the mote;
an RFID reader configured to sense a presence of one or more RFID tags and to transmit data regarding the one or more RFID tags wherein the one or more RFID tags are each associated with capital equipment that is monitored by the wireless mote network; and
an actuator configured to control one or more external systems;
a central communications device configured to communicate directly with a first subset of the plurality of motes within a range of the central communications device and to communicate indirectly with a second subset of the plurality of motes not within the range of the communications device via multihop communications through the first subset of the plurality of the motes; and
a controller configured to communicate with the central communications device, via at least one of cellular communications system and a satellite communications system, to receive one or more signals indicative of the environmental condition of one or more of the plurality of motes, and to transmit one or more control signals indicating an operation of the actuator to one or more of the plurality of motes, wherein a position of at least one of the plurality of motes is unknown and wherein the controller includes a server configured to generate a map of a relative location of the plurality of motes based on a signal strength of a wireless communication between the plurality of motes,
wherein each of the plurality of motes records data corresponding to each of the identification signals observed by the mote, wherein the data corresponding to each of the signals observed by the mote comprises the identification number of the mote that emitted the signal, the time that the signal was emitted, the identification number of the mote that observed the signal and the time that the signal was observed.
