1. A system comprising:
- one or more processors; and
one or more computer-readable storage media storing instructions that are executable by the one or more processors to perform operations including;
selecting a set of wireless channels for routing a communication session, the set of wireless channels including one or more non-contiguous wireless channels;
selecting a spreading sequence for spreading data of the communication session based on one or more attributes of the set of wireless channels;
communicating identifiers for the set of wireless channels and the spreading sequence to a remote device;
receiving sub-signals over the set of wireless channels including the one or more non-contiguous wireless channels;
combining the sub-signals into a combined signal; and
demodulating the combined signal with the spreading sequence to obtain a stream of communication data as part of the communication session.

Abstract
Techniques for spread spectrum wireless over non-contiguous channels are described. In at least some embodiments, a set of channels is selected for wireless communication, with at least some of the channels being non-contiguous (e.g., non-adjacent) from one another. A spreading sequence is selected, such as based on attributes of a selected set of channels. Communication data that is to be transmitted over the set of channels is combined with the spreading sequence to generate a spread spectrum signal. The spread spectrum signal is then divided into multiple sub-signals for transmission over the set of channels.
