DMR & NXDN wide area & in-building coverage
WIDE AREA & IN-BUILDING COVERAGE
In addition to digital Conventional and Conventional IP linked systems, KENWOOD offers ITU Recognised NXDN Centralised Control (Type-C), Distributed (Type-D) and enhanced Type-C (Gen2) trunked solutions and ETSI DMR Standard TS 102 361-4 compliant DMR Tier III Trunked, Multi-Frequency and Simulcast systems which give users the ability to precisely match specific operational requirements in a cost effective and future-proofed radio system solution.
Users migrating from analogue systems can be reassured that all KENWOOD digital systems incorporate native analogue/digital mixed mode operation allowing you to continue to use existing analogue devices until they are replaced with digital devices.
KENWOOD NEXEDGE NXDN TRUNKING
KENWOOD NEXEDGE NXDN employs true 6.25kHz FDMA technology to offer greater spectrum efficiency, extended coverage and lower infrastructure costs. The low Bit Error Rate (BER) of NXDN improves clarity of reception in fringe areas, effectively increasing coverage by up to 30% increase in coverage area.
When compared to digital 12.5 kHz bandwidth technologies, the increased coverage of KENWOOD NEXEDGE NXDN results in significantly reduced infrastructure costs by requiring fewer sites to achieve the same coverage area.
SINGLE SITE NEXEDGE NXDN TYPE-D TRUNKING
KENWOOD NEXEDGE NXDN Type-D Trunking is a digital Logic Trunked Radio (LTR) protocol. Unlike Type-C trunking, there is no dedicated control channel where all channels available in the system can operate as traffic channels. Like LTR, there is no registration. This cost-effective solution thus offers spectrum efficiency and simplicity in single site operations.

MULTI-SITE NEXEDGE NXDN TYPE-C TRUNKING
Type-C (Centralised Control) uses a dedicated control channel in a distributed architecture. The trunking controller embedded in each repeater offers excellent redundancy and an extremely robust multi-site network. NEXEDGE Type-C trunking provides increased capacity, enhanced call capabilities, improved security and faster communications with less user interaction than conventional systems. The system automatically pools resources across multiple sites and assigns channels for faster, efficient use of the available spectrum.
ENHANCED NEXEDGE NXDN Gen2 TRUNKING
KENWOOD NEXEDGE Gen2 (Generation 2) offers a quantum leap in trunked network size and capacity: the maximum number of Type-C sites than can be connected is in excess of 1,000, while up to 64-channels can be accommodated in a single site. NEXEDGE For users requiring large-scale digital trunked networks, Gen2 has the features, capabilities and performance to satisfy all requirements.
KENWOOD DMR-S TRUNKING
KENWOOD’s proprietary S-Trunking is a simplified, cost effective DMR-based trunking solution that allows trunked system operation on shared channels and can be configured as a single or a multisite solution. KENWOOD DMR S-Trunking can accommodate up to 15 sites and 16 channels per site (8 Carriers/Repeaters -1 Control Channel + 15 Payload Channels).
KENWOOD KAIROS repeaters are software-upgradeable to support single site S-Trunking functionality. S-Trunking is a DMR-based trunking solution that allows trunking operation on shared channels.
KENWOOD KAIROS S-Trunking can be configured as a multisite solution. This configuration is perfect for applications where exclusive channels are unavailable.
DMR TIER III TRUNKING
KENWOOD DMR Tier III Trunking is ETSI DMR Standard TS 102 361-4 compliant and employs a Trunked System Controller (TSC) in an IP-based system architecture with dedicated control channel to optimise capacity and system availability.
A KENWOOD DMR Tier III system can be configured to accommodate a virtually unlimited number of sites with up to 400 channels per site and with the addition of KENWOOD’s powerful and cost-effective KAS-10 and KAS-20 AVL and Dispatch applications, Tier III compatible repeaters and NX-3000 and NX-5000 Series portable and mobile radios, a single or multisite DMR Tier III trunked system has never been easier.
KENWOOD DMR Tier III based trunking is the ideal solution for high density users who want to take advantage of the advanced Tier III features an open standard provides. The distributed architecture allows for single or multiple soft trunking controllers while managed by a Network Management System (NMS) controller and network.
DMR TIER III SIMULCAST
A KENWOOD DMR Simulcast network allows all repeaters to synchronise transmissions in time, effectively creating a large single cell which significantly reduces the time required for transmissions to reach a radio terminal or to locate the correct base station. Radios connected to a KENWOOD Simulcast network can move from one radio site to another without the need for the user to change channels. The ability to migrate between sites seamlessly allows dispatchers to broadcast to all sites simultaneously secure in the knowledge that communications will automatically be channeled to the site with the strongest signal.
Multiple KENWOOD DMR Tier III single site systems can be connected together over an IP network to create a Simulcast DMR Tier III trunking system where a distributed software controller can be deployed to provide enhanced redundancy.
