All NEXEDGE® equipment operates in 25 & 12.5 kHz analog and 12.5 & 6.25 kHz NXDN® digital modes – satisfying spectrum requirements today & tomorrow.
Migration by Design
NEXEDGE® extends the life of current radio system assets. All NXDN® digital modes use the same Class-C power amplifiers and site management equipment used for current analog stations, ensuring return on investment (ROI) and a multitude of supplier choices. Current analog and NXDN® digital fleets can share a NEXEDGE® base/repeater station in 12.5 kHz conventional "Mixed Mode," thus providing uninterrupted service as long as needed and a straightforward migration path as aging analog fleets are replaced with digital. Also, NEXEDGE® trunked traffic channels can be shared with existing external analog conventional or trunked logic controllers, extending service to fleets as a transition to NXDN® trunking is underway.
Variety of Operation
NEXEDGE® systems are configurable in traditional conventional, trunked and wide area trunked network operation modes. IP connectivity for NEXEDGE® trunked sites provides scalability over existing LAN/WAN assets and services.
Outstanding Voice Quality
The AMBE+2™ Vocoder is a state-of-the-art voice compression digitization technology that offers superior clarity at varying signal strengths, even at highway speeds.
Sound quality comparison between digital and analog transceivers
NEXEDGE® technology offers inherent security against casual electronic eavesdropping via its NXDN® digital air interface. It also includes NXDN® voice & data scrambling for security against external threats while providing confidentiality within the same system and talk group. Inter-network links are further secured through encrypted VPN tunneling. Also NEXEDGE® multi-site network operators can automatically validate individual subscriber radio hardware by ESN (a unique factory-embedded Electronic Serial Number ) rather than changing the system's unit and group ID lists in the event a unit is lost, stolen, or removed permanently or temporarily from service.
More Information in Less Time
All NEXEDGE® system operational modes – conventional, trunked and networked – share exceptional feature benefits. The 65,519 IDs for a conventional system and 60,000 IDs for a trunked system accommodate large fleet and multi-user shared systems for dispatch talk group calling and individual private unit-to-unit calling. Unit ID/Group ID validation facilitates subscriber access and call privileging. Paging reduces unnecessary voice traffic and each subscriber unit stores the last 5 pages for recall. Especially useful on mobiles, a voice storage option can be added for stored-voice message paging. Emergency features can alert a dispatcher, a supervisor or a whole talk group to a unit in distress. The All Group Call feature supports system/facility-wide general, emergency or evacuation communications. Also, NEXEDGE® original Over-the-Air Alias provides instant caller ID regardless of fleet programming. Remote Stun and Kill features temporarily or permanently disable lost or compromised subscriber units to prevent system interference, while Remote Check enables a dispatcher to make non-voice in-range subscriber unit checks. All subscribers have simultaneously voice and GPS capability for automatic fleet tracking.
Asset Management with ROI
The NEXEDGE® System Manager for NXDN® trunked sites and networks reduces operational and maintenance costs with remote programming, firmware uploading, subscriber unit privileging, monitoring and diagnostics capabilities all from a secure user-friendly Windows®-based application via direct connection, dial up modem, or IP connection.
