The Hytera Simulcast System comprises of DS-6310 base stations and at least one Mobile Switching Office (MSO) per 100 base stations. The individual network constituents are connected with each other via an IP transport network. The base station of the simulcast system has the tried-and-tested RD985s repeater technology from Hytera at its core (maximum of 2 per base station).
Modular in structure for ease of operation and maintenance, the Hytera simulcast system can be operated with both line dispatcher (LDS) and radio dispatcher solutions for efficient communication and simple management of the radio subscribers.
The Network Management System ensures efficient administration of the mobile radio system by providing comprehensive functions for monitoring, operation, and maintenance. In addition, the configuration of software and hardware components is facilitated. Several workstations can be connected thanks to its client-server architecture, whilst central management of network elements and software updates can be controlled by remote access. Gateway configuration for PABX or PSTN connection is also possible, permitting communication between the radio system and telephones via SIP protocol.

Analog and Digital Operation
The Hytera simulcast system is capable of both analog and digital operation. CTCSS and CDCSS signalling systems are supported in analog mode. However, the greatest value is obtained in digital mode. Here, two calls can take place simultaneously on one frequency and data transmission services are also available.
-
Extensive range of compatible devices
The simulcast system is based on the DMR standard for conventional digital radio (DMR Tier II). This ensures compatibility with numerous Hytera radios – Analog or DMR.
-
Flexible IP Network
The IP-based system architecture provides flexible networking and makes low demands of system connections. Based on commercially available network technology such as servers, switches and routers, the IP transport network of the simulcast system is cost-effective to maintain and upgrade.
-
Full-area radio coverage with just one frequency pair
The simulcast technology means that only one frequency pair is required for the mobile radio system, regardless of the number of base stations on the network.
-
High voice quality thanks to “Dynamic Voting”
The excellent voice quality of the simulcast system fully exploits the strengths of digital radio. In addition, the system also ensures that ideal voice quality is guaranteed in areas where the radio coverage of two base stations overlaps. The mobile switching office ensures, by means of quality check, that the best radio signal is forwarded and broadcast in each case.
-
Increased capacity through intelligent system management (Subnetting)
Using the network management software, the simulcast system can be divided into different subnets depending on base stations and the time slots of a repeater. Each subnet operates as an independent mobile radio system and can provide additional capacity in certain areas. Subnets can be temporarily connected with each other in order to react quickly to changed conditions.
-
Smooth Roaming and Handover
Users on the Hytera Simulcast system can move between sites without having to worry about changing channels, and dispatchers can rely on transmissions being broadcast from all sites simultaneously with received communications being automatically channelled through the site with the strongest received signal.
