The maximum wireless signal rate for the system is derived from IEEE Standard 802.
11b/ g/n specifications. Actual data throughput will vary. Network conditions and
environmental factors, including the volume of network traffic, building materials and
construction, and network overhead, may lower actual data throughput rate.
Environmental conditions will adversely affect wireless signal range.
