1. A wireless communication system, comprising:
- a wireless hub configured to send downstream communications on at least one of a set of predefined downstream channels and receive upstream communications on at least one of a set of predefined upstream channels;
at least one wireless modem configured to receive said downstream communications, and send said upstream communications;
wherein said wireless modem comprises,an acquisition unit configured to acquire a predefined downstream channel transmitted by said hub and read Downstream Channel Descriptor (DCD) messages describing available downstream channels,a scanning unit configured to scan the available downstream channels, anda selection unit configured to select the best available downstream channel.

Abstract
A system and method for communication between a wireless modem and wireless hub on a selected downstream channel of a plurality of downstream channels is provided. The selected downstream channel is selected by the wireless modem after receiving communication parameters for each of the downstream channels and selecting the selected downstream channel by determining the most efficient of the downstream channels at that time for downstream communication.
