1. Point Of Interface Multi Band Combiner
Description
Point of interface (POI) is a platform for multi-combining system for Basestation and DAS
It combines several mobile carriers(operators) BTS or DAS system two or four
output port(Comport) for distributed antenna system.
At the same time, it distributes the different uplink signals to their each system,
realizing multi-band and multi-signal combination and using simple two or four
Com Antenna portsThis is a feasible and efficient measure of realizing the coverage by signals
from multi-networks.
Key Features
High Performance and high reliability
Cost effective antenna sharing solution for outdoor and indoor applications
19 inch Rack Type.
Effective in time and installation as it easy and fast.
Support building esthetical aspect by reducing number of indoor antenna.
Multi band Support.
Good isolation good power handling ability and excellent IMD.
