•Internal antennas version labeled “i” that has captured antennas (part of the housing and not removable). The “i” series is designed for indoor Enterprise installations where office aesthetics are a primary concern.

•External antennas version labeled “e” that is more rugged and designed for industrial use in locations such as hospitals, factories, and warehouses, anywhere a need exists for external antennas and/or extended operating temperatures. The “e” version also supports mounting inside NEMA enclosures for use in the most demanding environments.
