US Patent 9143968 Wireless spectrum monitoring and analysis

In some aspects, a wireless-spectrum analysis system is described. In some examples, the wireless-spectrum analysis system includes wireless-spectrum analysis devices distributed at distinct locations over a geographic region. The wireless-spectrum analysis devices are configured to concurrently monitor wireless-spectrum usage at each distinct location. Each wireless-spectrum analysis device is configured to transmit, from the wireless-spectrum analysis device, spectral-usage parameters identified by the wireless-spectrum analysis device based on wireless signals detected by the wireless-spectrum analysis device at its distinct location. The wireless-spectrum analysis system further includes a data aggregation system configured to aggregate the spectral-usage parameters transmitted from the wireless-spectrum analysis devices.
