An alternate use of this repeater is for indoor applications. The MirrorCell

II makes
great economic sense for buildings that are too large for the EkoMini repeater, but too
small to justify a fiber optic DAS (Distributed Antenna System). One MirrorCell II can
cover most typical buildings up to approximately 200,000 square feet using ½” coax
and several power dividers feeding approximately eight indoor server antennas.
Figure 3 shows a typical example. Also, directional couplers with varying levels of
coupling values may be used to tailor the power delivered to each building floor for
optimal coverage.
The MirrorCell

II has these features:

90 – 95 dB gain in a range of models with up to three composite
RF output power levels available.
 Output power level may be incremented in one dB steps over a 30
dB range, either automatically with built-in software, or manually
with software commands.
 An optional battery back-up unit is available to maintain repeater
operation for several hours during AC power interruptions
 Receive diversity is available as an option.
