Architecture

Hytera DMR simulcast system consists of MSO (Mobile Switching Office), Base Station , Dispatch System, NMS, Service Terminals and Bearer Network. One MSO supports up to 100 Base Stations or 200 carriers. A single DMR simulcast Base Station can support up to 2 carriers.

 
Key Features
 
Higher Spectrum Efficiency
·Simulcast technology requires a single pair of frequencies (one for TX and the other for RX) regardless of the number of BSs in the network.
·DMR two-slot TDMA technique supports 2 simultaneous communications on a single 12.5 kHz radio channel.
 
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 preformance in overlap area as radios in overlap area can awlways receive the best voice frame through dynamic voting.
·MSO will analyze each voice frame received from multiple base stations in real time. The best voice frame will be extracted and sent to radios.
 
Flexible Networking
·The IP-based architecture enables flexible networking.
·Multiple transmission links can be used between BS and MSO, such as IP, E1, Microwave, wireless bridge, etc.
·The standard SIP and RTP are used to interconnect with other systems such as PSTN system, DMR trunking system.
 
Analog/Digital Self-adaptive
·Simulcast base station channels support working both in analog and digital mode, 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 a independent simulcast system.
·Different subnets can be patched to make a larger subnet temporarily according to the requirements.
 
Dedicated GPS Channel
·In order to increase the GPS data transmission capability, a dedicated GPS channel can be used in DMR simulcast Base Station.
 
Versatile Services
·Voice services: private call, group call, all call, emergency call, broadcast call, dispatcher call, PSTN call, etc.
·Data services: text message, status message, emergency alert, GPS data polling, AVL, etc.
·Advanced services: end-to-end encryption, late entry, discreet listening, voice recording, etc.
 
Long Time GPS Holdover 
·In case of GPS failure, the base station supports a holdover of 48 hours via the internal synchronization reference, ensuring that the simulcast service maintains normal. 
 
Open API
·Open API for further service development, such as dispatch service, network management service and GIS service.
 
Network Management System
 
The network management system is composed of server and clients. It is designed to remotely control the simulcast system.
·Various management capabilities: system configuration management, fault management, security management, topology management, etc.
·Support SNMP.
·Adopt C/S structure to support multi-user operation.
·Provide API for further development.
 
 
Dispatching System
 
The dispatching system  is designed for efficient communication, management and dispatching of professional users in Hytera DMR simulcast system. 
·Automatic Vehicle Location (AVL)
-Multiple maps (Google map or MapInfo ) support.
-Terminal location real-time tracking & display.
-Track playback.
-Geo-fencing.
·Voice Service
Private call, group call, broadcast call, emergency call, etc.
·Data Service
Text message, status message, GPS Polling and emergency alert.
·Other Service
Stun/revive,voice recording,subnet patching,etc.
 
DMR Simulcast Terminals
·The most complete DMR terminal portfolio. Portable radio PD5 series, PD6 series, PD7 series, X1e and X1p, mobile radio MD78X, intrinsically-safe radio PD79X Ex.
·Four-mode DMR terminals support analog conventional mode, DMR conventional mode, MPT Trunking mode and DMR Trunking mode.
·The smallest full power DMR portable terminal in the world-X1e & X1p.
·Most of the terminals support software upgrade from conventional mode to trunking mode.
·Most of the portable terminals support build-in GPS and IP67, all terminals support MIL-STD-810C/D/E/F/G.
