NXDN™ Radio

The NXDN protocol is an advanced digital communications standard jointly developed by Icom (IDAS system) and Kenwood (NEXEDGE system). Like dPMR, it utilizes FDMA (Frequency Division Multiple Access) technology to maximize spectrum utilization.

NXDN (NEXEDGE/IDAS) Radios – Narrowband FDMA Efficiency

NXDN is a professional digital communications protocol developed jointly by Icom (IDAS) and Kenwood (NEXEDGE). It is an FDMA system characterized by exceptional spectral efficiency, offering operation on narrow channels of 6.25 kHz and 12.5 kHz. Thanks to the advanced AMBE+2 vocoder, NXDN radios provide crystal-clear audio, noise reduction, and excellent coverage, especially in challenging signal conditions.

The NXDN system is designed for the most demanding users—from simple conventional networks to advanced, multi-site IP trunking networks.

Key Advantages and Features of the NXDN System:

• Extreme Spectral Efficiency (FDMA): Ability to operate on very narrow 6.25 kHz channels, allowing for twice the capacity of traditional 12.5 kHz channels, optimizing the use of available spectrum.
• Excellent Voice Quality: The AMBE+2 vocoder and digital technology eliminate background noise, ensuring clear and distinct communication even with weak signals.
• System Scalability (IP Trunking): NXDN enables the construction of extensive systems IP trunking (e.g., NEXEDGE), connecting up to 16 zones and serving tens of thousands of users with automatic roaming.
• Security and Flexibility: Offers advanced encryption options (e.g., 40-bit ARC4), and many radio models are multi-protocol (NXDN/DMR/Analog FM), which facilitates migration and ensures interoperability.
• For Demanding Applications: Ideal for industry, transportation, logistics, and public services, where reliability, range, and privacy of communications are key.
• Choose NXDN radios if maximum bandwidth utilization, the highest voice quality, and the ability to build extensive, professional radio networks are your priorities.
