The FiRe-78-4 from ADRF Tech is a Fiber Optic Repeater designed for use in the public safety 700 and 800 MHz bands. This FirstNet compliant in-building wireless solution combines ADRF's PSR-78-9533 public safety 700/800 MHz channelized repeater with the flexible ADXF series Distributed Antenna System (DAS) Head End (HE) in a single compact enclosure. It delivers a gain of over 85 dB and has a VSWR of less than 1.5:1. The device consumes up to 135 watts of power while operating over an AC supply voltage from 100 to 240 V. It provides up to 33 dBm of composite output power per remote.
Through the use of digital signal processing (DSP) filtering technology, the FiRe-78-4 helps eliminate adjacent channel interference to allow band selectivity. It can reduce the equipment cost by up to 40% and also allow savings for overall infrastructure spending by providing all equipment in an IP66 rated enclosure eliminating the need to purchase additional enclosures.
A single FiRe-78-4 can cover over 500K sq. ft. and can be monitored via ADRF's web-based GUI, which provides versatility and total control to the user as well as alarming outputs to supervised circuits for antenna, amplifier, power supply, battery, and charger failures. It is a perfect public safety communication solution for enterprises. This repeater is available as a benchtop unit that measures 11.03 x 21.28 x 10.01 inches with 4.3-10 (F) and 2 SMA connectors. The FiRe-78-4 is compliant with NFPA Codes. It simultaneously supports FCC Part 90 Class A narrowband and Class B wideband repeater designations
