Explanation
Please explain in the area below why an STA is necessary:
An experiment will be performed to test the ability of a smart radio to switch between two different modes of communication based on detected channel activity from conventional radios. All communication will be at low power (1W or less). The conventional radios are licensed for Europe, one is a digital walkie-talkie and the other is a GSM base station and handheld unit. These operate in bands that correspond to a mix of unlicensed and broadcast licensed bands in the U.S. An STA is required in order to operate in these bands.

Purpose of Operation
Please explain the purpose of operation:  Demo of smart radio technology The University of Colorado is performing experiments to demonstrate new radio technologies for the Air Force. The experiments use an experimental radio that is able to tune to multiple different frequencies and select a transmit frequency based on the strength of received signals on each channel. The radio is intended to be mounted on a small unmanned aircraft that flies 100m above the ground. While laboratory and anechoic chamber experiments will prove useful, it is not clear how well the radio will perform in a complex radio environment. To validate the concept in a realistic environment, a series of experiments are being planned to be performed at the NTIA Table Mountain Radio Quiet Zone near Boulder Colorado. Each experiment will be brief (1 hour or less). However, to test different configurations, several experiments starting in late July will be performed. The European radios are chosen, in part, because their operating frequency can be selected to avoid occupied bands in the vicinity of Table Mountain and in part due to requirements specified by the Air Force. The experiments will take place at Table Mountain within a circle of radius 1km. Transmitters will be present at 106.5MHz, 903.4MHz, and 948.4MHz. Transmitters will be present on the ground (below 6m) and also in the unmanned aircraft which will fly below 100m. The 106.5MHz signal bandwidth is 25KHz. The other two signal bandwidths are 350KHz.
