  • a white space channel on which a white space device and a wireless narrowband device seek to operate; and

    an assistance component that assists the white space device in operating on the white space channel concurrently with the wireless narrowband device, by;

    sending notification to the white space device of operating presence of the wireless narrowband device on the white space channel, in response to which the white space device initiates an incremental transmit power ramp-up mode, andsignaling the white space device of impending audible interference of the white space device with the wireless narrowband device, in response to which the white space device ceases transmission in a specific portion of spectrum in which the narrowband device transmits to prevent interference with usability of the wireless narrowband device, the specific portion of spectrum being substantially less than an entire channel portion of spectrum that is specifically associated with the white space channel.
