iDEN Microcell Overview

CCIs iDEN Microcell provides EBTS support in

tight spaces where a traditional Nextel base

station would never fit and at a fraction of the costof a shelter alone.

The unique outdoor cabinet design allows for

multiple configuration and mounting options:

The lower (battery) and main cabinets can be

mounted separately on a pole or pad, for sites

where floor or ground space is at a premium.

The entire unit can be outfitted with wheels for

mobility and flexibility.
