1. Introduction
PSR is an innovative channelized digital repeater for public safety FirstNet and 700MHz and 800MHz wireless
communication, in a small and large building for emergencies.
Thanks to the accumulated digital filter technology, up to 64 narrowband filters with independent gain and
output adjustment can be configured and work together, up to 32 in each of 700 and 800 bands, while minimizing
adjacent channel interference.
Also, in case of having different bandwidth by region, PS700 / PS800 frequency band can be adjusted and
designed to detect and adjust system gain. All functions of the repeater are implemented in Web-based GUI to
maximize the convenience of management.
User should follow instructions which are described in FCC notices in case of class B device.
