The Nextedge NX-200/300 is the digital radio from kenwood, all NEXEDGE™ Products use advanced DSP-driven digital voice technologies and support both FM analogue and new digital fleets. System type conversion or expansion only requires software options and/or additional base station units, i.e., no “major” upgrading. Kenwood offers Conventional, conventional IP networks, trunked and wide area trunked IP networks solutions with secure digital voice and an array of advanced digital feature sets for business and government sector.
NEXEDGE™ is powered by the NXDN® digital air interface, an FDMA digital access methodology generated with optimized DSP coding, AMBE+2™ voice coding technology, unique filtering and a 4-level FSK modulation technique producing an industry-leading low bit error rate (BER) digital performance even at weak RF signal strengths.
As RF signal strength weakens with distance, FM analogue reception becomes increasingly noisy and intermittent. NXDN®’s low BER improves reception in fringe areas, thereby increasing the effective range by as much as twenty percent over analogue FM NEXEDGE™ includes unit ID, emergency, GPS location, status and messaging capabilities in both FM and NXDN® digital modes.
A calling units UID alphanumeric alias is sent over the air and displayed on a receiving unit’s LCD, so there is no need to program every fleet alias in every radio enables a dispatcher to temporarily or permanently disable a lost, stolen or compromised radio unit over the air for system security and personnel safety.
A selectable All Call GID calls all talk groups on the system for facility wide announcements, emergencies and evacuation scenarios.
NEXEDGE™ offers voice security that enhances personnel safety, reduces risk exposure and thwarts competitive breeches by protecting sensitive communications for your facilities and operations. Inherent Level of Security The NXDN® digital air interface itself prevents casual eavesdropping.
The NEXEDGE™ KPG-110SM System Manager reduces operational and maintenance costs with remote programming, firmware uploading privileging, monitoring & diagnostics capability from an operator-friendly secure Windows® application (for NXDN® Trunked sites and networks only)
