Setting up a wireless network for optimal coverage is a unique process for any given implementation, so there is no one best answer. However, each device in the MR product line has its own coverage patterns. These patterns can be used as a general positioning guide, then an admin can select which radio channel to use for the least amount of interference. Furthermore, the outdoor MR units can be attached to an antenna to optimize coverage.
