Hytera DMR Tier 2 Conventional Repeater Systems

Hytera DMR Tier II radio conventional repeater systems provide significant benefits, including enhanced coverage, expanded call capacity, improved signal quality, security features, flexible interconnectivity, and advanced management and dispatching capabilities.

DMR Tier II is a digital radio standard that provides voice and data communication capabilities. It operates on licensed frequency bands and employs a two-slot TDMA (Time Division Multiple Access) technique, allowing for two separate conversations to occur simultaneously on the same frequency channel. DMR Tier II radios offer features like private calls, group calls, text messaging, and advanced voice quality.

A repeater acts as an intermediary device that receives signals from a transmitting radio and retransmits them at a higher power, increasing the range and coverage area. If your communication needs extend beyond the capabilities of a simple radio-to-radio system, a repeater can provide the required coverage across larger areas, multiple floors, or outdoor environments. Repeaters also provide an intelligent and seamless communication platform with the flexibility to connect with a variety of systems, including phone systems, IP networks, and other radio systems. All Hytera DMR radios and any third-party DMR compliant radios are supported on Hytera Tier II repeater systems for flexible interoperability.

Hytera IP Connect Multi-Site Repeater Radio System

IP Connect is designed for organizations that operate across a large area or geographically separated locations that exceed the coverage area provided by a single repeater. With Hytera IP Connect, multiple repeater sites can be linked together over a standard IP network, allowing users in different locations to talk over wide areas with ease.

IP Connect allows for connecting multiple DMR Tier II conventional repeaters across dispersed locations using third-party IP networks. That includes wide area networks like the internet, Local Area Networks, VPNs, or microwave links. IP Connect is achieved with a simple license upgrade on the Hytera repeater, so there is no additional radio equipment required.

XPT Delivers the Advantages of a Trunked Radio System at a Lower Cost

Developed exclusively by Hytera, the Extended Pseudo Trunking (XPT) system is based on the ETSI DMR Tier II Conventional Standard and adds capabilities normally found in higher cost Tier III trunking systems.

XPT makes DMR Tier II repeater systems more efficient to provide more channel capacity and adds valuable new features without the purchase of additional radio infrastructure hardware.

Hytera DMR Tier 3 Radio Trunking Systems

Trunked Radio systems optimize voice or data traffic through a limited number of frequencies, maximizing the available resources for a large group of users. DMR Tier III Trunked Radio utilizes repeater technology with a dedicated control channel, managed by a server.

The Hytera DMR Tier III Trunking has been developed using the ETSI DMR open standard. It is an IP-based Digital Trunking System designed to provide voice, dispatch, and radio management capabilities across wide geographic areas.

DMR Tier III provides a dedicated FCC FB8 frequency control channel for radios to register and request service from the network. The remaining channels in the system are allocated to the radio as they are needed and are therefore a shared or “trunked” resource called a “traffic channel”. As soon as a traffic channel is available, a user will be assigned to use the channel, without having to wait for a specific channel to become available.

The Hytera DMR Tier III Trunking solution consists of a central controller called a Mobile Switching Office (MSO), a Base Station Controller Unit (BSCU) at each radio site, multiple repeaters to carry the traffic, and a wide area network that connects all the different pieces together. IP connectivity is provided by a variety of third-party internet, LAN, or VPN network operators.
