Which NEXEDGE configuration is right for you?

Conventional
NEXEDGE conventional systems offer capabilities beyond analog conventional systems. With large unit ID and talk group ID capacity, operators can identify and segment different departmental groups and sub-groups on shared channels. Mixed Mode allows analog and digital fleets to share the same RF channel.

Conventional IP Network: Coverage
Conventional IP networks offer the ability to link two or more sites via IP network infrastructure to provide wide-area coverage across geographic areas. Subscriber zones on the network can be programmed for “Normal Channel Select” for traditional conventional operation or “Automatic Site Roam,” which allows NX radios to scan for site beacon signals that are transmitted periodically from all sites and automatically roam onto the site with the best signal strength. Which NEXEDGE configuration is right for you?

Conventional Simulcast: Coverage
Conventional Simulcast allows multiple geographically separated IP networked sites to transmit on the same frequency simultaneously, reducing the number of frequencies needed for the system and simplifying frequency coordination. This configuration is ideal for situations where limited frequencies are available or when improved in-building radio coverage is required. A simulcast controller located at one of the conventional sites synchronizes the system timing so that calls are transmitted simultaneously at all sites and subscriber radios receive the signal from multiple transmitters, allowing users to move between sites with no operator intervention.

NXDN Type-C Trunking Gen1: Capacity & Coverage
NXDN Type-C offers Control Channel-based trunking that automatically assigns channels for faster and more efficient use of spectrum. The NEXEDGE Type-C Generation 1 (Gen1) trunked system offers increased call capacity, enhanced call capabilities, improved security, and faster communications with less user interaction than conventional systems. The network option leverages the power of IP to create scalable networks over existing IT assets, private microwave, spread-spectrum links, or carrier services using standard Ethernet switches and routers. The 60,000 Group ID and Unit ID network capacity is sufficient for large organizations and multi-user system sharing.

NXDN Type-C Trunking Gen2: Capacity, Coverage & Control
NEXEDGE Gen2 is built on a server-based architecture that utilizes IP Network standards, designed to accommodate the need for expanded capacity. Gen2 provides more sites, centralized configuration, and enhanced management capabilities, with seamless roaming and compatibility with commercially available SNMP network monitoring applications. The System Controller Server is at the heart of the Gen2 infrastructure, acting as a media server for the connected sites and playing a key role in directing voice traffic throughout the radio network. Controllers can support up to 1,152 sites and 24 System Codes, linking multiple sites and channels for higher reliability at a lower cost. This allows operators to update and expand their NEXEDGE systems without any service disruption.

Standards-Based System

NEXEDGE operates on the widely supported NXDN open-standard Common Air Interface (CAI) for mobile communications. NXDN has been recognized by the International Telecommunications Union (ITU) as an International Open Standard. The NXDN Forum, a multi-faceted membership organization established in 2008, allows any manufacturer to develop products using the NXDN CAI without any fees, creating an open, competitive development environment free from unnecessary restrictions. Data applications such as AVL/mapping, Push-to-talk Over Cellular (PTToC), event logging, and messaging have become increasingly important management and operational requirements for utilities and industrial users. The KENWOOD Solution Developers program is a network of third party software and hardware vendors who work in close collaboration with JVCKENWOOD engineering, research, and development teams to provide data applications and gateways for NEXEDGE products. JVCKENWOOD also offers integration support to integrate NEXEDGE System solutions with third party data application providers.

Futureproof Communication
The NXDN air interface is unique in that it is capable of fitting into both 12.5 kHz “narrow” and 6.25 kHz “very narrow” bandwidth channel operation to ensure frequency stability that exceeds all regulatory requirements in all bands.

The ability to operate in 6.25 kHz bandwidth mode offers:

  • Extended coverage — The high carrier-to-noise ratio of the narrower bandwidth allows for 30% wider coverage area compared to digital 12.5 kHz operation.
  • Extra protection from interference — Operating at 12.5 kHz has the potential to cause interference with a neighboring system; this problem is eliminated with a narrower bandwidth.
  • More available frequency licenses — 12.5 kHz frequency licenses are often more difficult to obtain than 6.25 kHz licenses, especially in large urban areas.
