HELIOS® DIGITAL MOBILE RADIO SFR700 SINGLE FREQUENCY REPEATER

Cost-Effective Coverage for Radio to Radio

Overview

Digital Mobile Radio (DMR) is a digital radio standard specified for professional mobile radio (PMR) users developed by the European Telecommunications Standards Institute (ETSI), and first ratified in 2005.

DMR operates within the existing 12.5kHz channel spacing used in licensed land mobile frequency bands globally and meets future regulatory requirements for 6.25kHz channel equivalence. The DMR protocol covers unlicensed (Tier I), licensed conventional (Tier II) and licensed trunked (Tier III) modes of operation, although in practice commercial application is today focused on the Tier II and III licensed categories.

Keeping your team connected requires uninterrupted radio coverage. But often, network dead zones and remote locations present barriers to seamless communication.

Unlike traditional repeaters, A HELIOS® SFR700 series DMR Single Frequency Repeater (SFR) is based on SDR (Software Define Radio) technology with IP65-rated for dust and water protection, so you can fast deploy it on campuses, in parking garages and across other outdoor locations. The compact size gives you more installation options, such as mounting on walls or poles. Using interference cancellation technique, HELIOS® DMR Single Frequency Repeater (SFR) allocates one timeslot to receive a signal and the other to transmit it on the same frequency. In this way, it’s unique SFR feature enabled will repeat the traffic on slot 2 received on slot 1 without antenna isolation limits upon deployment on site, which help customers to save frequency resource, centralized controller or expensive license.

Coverage without complications

Whether you want to eliminate dead zones or expand coverage to remote locations, count on the HELIOS® SFR700. Compact, easy to install, and designed to work indoors or out, it’s built to grow as your needs do.
