Abstract: In an embodiment of the invention, a system may include one or more wireless transmitters and a transportable transmitter having at least one processor and at least one storage device. The transportable transmitter may be configured to communicate with the one or more wireless transmitters, store operational data in the storage device, encapsulate the operational data into a message, and transmit the message to establish a geographic protected contour for the wireless transmitter. The wireless transportable transmitter may, after transmitting the message, transmit information from within the geographic protected contour to a receiver outside the geographic protected contour while receiving interference protection on the transmitting frequency within the geographic contour.

Abstract: In an embodiment of the invention, a method may include receiving spectrum occupancy data regarding spectrum occupancy in a radio frequency environment, generating, with a processor, spectrum information regarding a plurality of transmission options for a transmitter based on the spectrum occupancy data, and providing the spectrum information to the transmitter.

Abstract: In an embodiment of the invention, a system may include a specially configured computer having at least one processor and at least one storage device. The computer may be configured to calculate an estimate of radio propagation and signal strength using a first radio propagation model. The computer may recalculate the estimate of radio propagation and signal strength using one or more additional radio propagation models. The computer may store the recalculated estimate of radio propagation and signal strength in storage.
