NXDN DIGITAL AIR INTERFACE

AP3500 radios employ NXDN, an FDMA digital air interface with AMBE+2™ voice coding technology, with forward error correction and unique filtering to obtain superior coverage even at weak RF signal strengths.

The NXDN air interface is capable of fitting into both 12.5 kHz and 6.25 kHz bandwidth channel operation to ensure rock-steady frequency stability, exceeding all regulatory and emissions mask requirements in all bands.

Analog / Digital Mode

AP3500 supports digital DMR and analog two modes to realize analog to digital upgrade and it can compatible with users'ooriginal analog devices.In the harsh communication conditions, digital mode has better performance than analog mode, and the voice is much clearer. 12.5kHz frequency bandwidth can offer two-channels voice communication, effectively improving the spectrum utilization efficiency.

NXDN Convention / NXDN Trunking

AP3500 supports 2 digital modes: DMR Convention and DMR Trunking

DMR Digital Trunking system is a large scale communication system that can cover a large area and communicate with multiple groups of users at the same time. n the trunking mode, AP3500 can offer rich calling applications through single-call, group call, group call and other calling functions.

Dual-slots

The free slot can be allocated to enhance frequency efficiency and timelyresponse under emergency.

Beidou/GPS Positioning (Optional)

AP3500 has built-in Beidou /GPS positioning module, which can support Beidou /GPS positioning data transmission under both conventional and trunking modes. In the trunking mode, the dispatcher can directly communicate with target communication units which selecting from the map

Reliable and Durable

AP3500 can meet with IP54 standard, its structure is reliable and durable. lt has outstanding performance on Shock AND Vibration and other harsh operating environment.

Application fields

Highways, Urban comprehensive law enforcement, Transportation and other fields which requiring long-distance communication and high reliability.
