Intelligent Super Repeater


Intelligent Super Repeater

The Hytera RD98XS is an impressive digital systems repeater. Supporting conventional analogue and digital modes, it can also be used in DMR trunked radio systems (Tier III), and with up to 50W power is responsible for delivering excellent coverage in DMR simulcast and Hytera XPT systems.


RD98XS is a 50W, DMR and analog dual mode upgradable repeater which can work in analog and DMR conventional modes. It can be upgraded to trunking or simulcast mode by software only. One step upgrade package makes it easy to operate in different modes, analog conventional, MPT-1327, DMR conventional, DMR trunking and DMR simulcast with only one hardware platform.

Conventional Features

▪Repeater Diagnostic And Control (RDAC)
RD98XS supports Remote (via IP port to connect to internet) and Local diagnostic (via USB) PC applications to monitor, diagnose and control the repeater status, thus increasing the maintenance efficiency. Hytera developed RDAC supports multiple master network connections, allowing radio administrator to monitor multiple radio networks upcoming.

▪Analog Digital Auto switch
RD98XS supports Analog and Digital channel auto switching, allowing efficient frequency sharing between Analog and Digital users during the digital migration.

▪Analog/Digital Back-to-Back Interconnect
RD98XS supports different operating modes of analog and digital to interconnect for voice cross patch, allowing analog users to communicate with the digital users and vice versa. This allows the smooth migration from analog to the digital world.

▪Dual Slot Digital Audio Streaming
RD98XS supports streaming of both the voice slots via the rear port accessory pins, allowing third party for capability expansion.

▪IP Multi-site Connection
Multiple RD98XS repeaters can form a private radio network via IP port interconnection, allowing wide area coverage to meet data and voice communication requirements in dispersed locations.

▪Analog/Digital Telephone Interconnect (via DTMF signaling)
RD98XS supports simplex voice communications between radio and telephone users. It allows a radio user to make a telephone call; or a telephone user to make either a Group or Private call to radio users.

▪Analog Scan
RD98XS supports Analog voice and signaling scan, allowing repeating of different Analog voice users from various groups.

▪Multi CTCSS/CDCSS Decode
RD98XS supports decoding up to 16 CDCSS/ CTCSS types on  analog channels, allowing repeating of different analog voice users from various groups.

Upgrade to DMR Trunking Transceiver

DMR trunking Lite 2 carrier BS, including Power Distribution Unit, 2 Transceivers (RD98XS) & Transceiver Power Supply, Switch, BS PSU, Base Station Controller, 2-channel RF System.

▪Open Standard
DMR Trunking Lite is based on DMR tier III standard, defined by ETSI in 2005, which is a digital radio standard for professional radio users. With dedicated control channel, DMR Trunking Lite can achieve versatile functions.

▪Smooth Migration
DMR Trunking Lite transceiver supports smooth migration from analog to digital, from conventional to trunking. Multi-modes provide you different choices for continual investment.

▪Integrated RF System
Intergrated 2-carrier RF system, significantly reduces the space and cost for divider, combiner and duplexer.

▪Non-centralilzed Structure Design
Non-centralized structure is only used for less than 5 base stations. It ensures a cost-effective and flexible networking especially suitable for small-scale network.

Upgrade to DMR Simulcast Transceiver

DMR Simulcast Single Carrier BS, including Built-in Router, Synchronized Expansion Unit, Transceiver (RD98XS) & Power Unit & Duplexer.

▪Smooth Roaming and Handover
In simulcast system, the radio is capable of roaming and handover seamlessly between different BSs , the ongoing communication can continue normally during handover.

▪Dynamic Voting
Simulcast system can provide good voice performance in overlap area as radios in overlap area can always receive the best voice frame through dynamic voting. As a voting center, MSO is used to analyze each voice frame received from Base Stations in real time. The best voice frame will be extracted and sent to radios.

▪Analog/Digital Adaptive
Simulcast base station channels support working in both analog and digital modes, to ensure smooth migration from analog to digital network. Digital or analog mode is automatically selected based on the incoming signals.

▪Smart Subnetting and Patching
According to management requirements, DMR simulcast system can be divided into different subnets by Base Station or by time slot of channel unit in each Base Station. Each subnet can work as an independent simulcast system. Different subnets can be patched to make a larger subnet temporarily according to the requirements.
