Abstract

The present invention is a mobile hotspot system comprising a first bi-directional antenna operably coupled to a transceiver capable of at least demodulation, modulation, and amplification and a second omni-directional antenna operably coupled to said transceiver; an electrical power source operably coupled to said transceiver. RF interconnections between said transceiver, said first bi-directional antenna, said transceiver and said second-directional antenna are also provided. The system is housed in a compact, weather-resistant radome, and optionally includes a power source, which may be one or more of batteries, battery chargers, and power connections.

Claims

1. A mobile hotspot system comprising:
