1. A wireless communication system comprising:

  • a wireless communication device, a communications management system, and at least one remote device,wherein said communications management system manages operations of the wireless communication device and said communications management system is operably connected to the wireless communication device,wherein said wireless communication device comprising;

    a first radio transceiver to receive and transmit radio frequency signals;

    an antenna element having capability to direct radio frequency signals to and from the first radio transceiver;

    a device communications management interface to provide communications between the wireless communication device and the communications management system;

    an asymmetric bi-directional radio frequency amplifier, said amplifier operationally interposed between the first radio transceiver and the antenna element, wherein the amplifier amplifies radio frequency signals received by the antenna element from the at least one remote device by a first gain and amplifies radio frequency signals transmitted from the first radio transceiver via the antenna element by a second gain, wherein the first gain is greater than the second gain, and wherein a maximum value of the second gain is a function of at least a maximum transmit power limit, and wherein the second gain of the amplifier is controlled by said communications management system to control the transmission power from the wireless communication device in a predetermined frequency band, said amplifier further comprising a filter to mitigate band-edge transmissions from propagating into upper and lower frequencies adjacent to the predetermined frequency band;

    a heat sink in thermal communication with the first radio transceiver and interposed between the first radio transceiver and the antenna element to dissipate heat from the wireless communication device; and

    a unitary weather protective housing, wherein the first radio transceiver, the device communications management interface, the amplifier, and the heat sink are contained within the unitary weather protective housing,wherein the first radio transceiver is positioned within 8 inches of the antenna element to eliminate substantially all appreciable power loss between the first radio transceiver and the antenna element;

    wherein the wireless communication device receives electronic information from said at least one remote device and transmits other electronic information to said at least one remote device, andwherein the wireless communication device transmits the electronic information from said at least one remote device to a communication system and receives the other electronic information from the communication system,wherein the communication system is connected to Internet, and said at least one remote device comprising;

    a second transceiver to receive and transmit radio frequency signals with the wireless communication device; and

    a second bi-directional amplifier, wherein said second bi-directional amplifier has a third gain for radio frequency signals transmitted from the second transceiver to the wireless communication device and a fourth gain for radio frequency signals received from the wireless communication device, wherein the third gain is less than the fourth gain.
