Access Points are available in two models see 
:
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.
