AP3500 SFR Digital Trunking Mobile Radio


AP3500 DMR Mobile Radio supports both Conventional mode and Truning mode. GPS/Beidou/GLONASS positioning function can be choosed to combine with command and dispatch software, which can be intuitively view the location of people on the map and make voice calls with them. AP3500 is very ideal option for in-vehicle or desktop communication. With SFR (Single Frequency Repeater) function that can simultaneously receives and transmits at the same time, on the same frequency to enhance frequency efficiency and timely response under emergency.

Product Orientation Map





AP3500 DMR Mobile Radio can support clear voice, diverse standards andrich functions of wireless communications services to the professional users.

1.77- inch LCD color display

The radio adpots 1.77- inch color LCD display, which makes the display information clearer even under strong light. Ergonomic design greatly improves the accuracy and comfort of operation.

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.

SFR (single frequency repeater)
Single Frequency Repeater (SFR) is a technology that uses TDMA technology to rebroadcast two way radio transmissions on the exact same physical frequency.
It can simultaneously receives and transmits at the same time, on the same frequency.
It does this by utilising DMR’s two time slots concurrently. The SFR receives on one time slot, whilst transmitting on the other.

DMR Convention / DMR 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.


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.
