Channel control for communications using dynamic spectrum access
By selecting and allocating channels on blank television spectrum, combined with GPS positioning and database queries, the problems of spectrum discontinuity and interference sensitivity are solved, enabling high-bandwidth, low-power communication for IoT devices, adapting to spectrum changes, and supporting large-scale IoT networks.

Abstract
This disclosure configures base stations and client devices to communicate using dynamic spectrum access within the spectrum, including selecting a set of channels from a list of available channels as active channels. Active channels include uplink channels and downlink channels, and are allocated among multiple base station radios of the base station. Different channels are assigned to different base station radios. Based on the location of the client devices, at least one uplink channel and at least one downlink channel are assigned to multiple client devices, with at least some client devices sharing a common active channel. Client devices sharing a common active channel are also grouped on the shared channel, and time slots are assigned to client devices within that group, thereby allowing the client devices to perform narrowband communication over the channel.
