Abstract

A wireless communication device generates and transmits wireless broadband signals at a power level that is below a spurious emissions mask such that the transmitted wireless broadband signals occupy a designated frequency spectrum band. A bandwidth of the wireless broadband signals may occupy approximately 800 MHz within a range of 0 Hz to 1 GHz. The transmit power utilized for transmitting the wireless broadband signals may be spread over a bandwidth of approximately 300 MHz within the 800 MHz bandwidth. The spreading results in a power spectral density of the transmitted wireless broadband signals approximating thermal noise at a distance of approximately 3 meters. Available channels within the designated frequency spectrum band may be sensed for the transmission of the wireless broadband signals. A plurality of the sensed available channels may be aggregated for the transmission of the wireless broadband signals.
