APEX1707 Vehicle-Mounted COFDM Transmitter

The APEX1707 is a vehicle-mounted COFDM transmitter built for mobile video transmission. It delivers 20 W of output power over a 300 MHz~2.7 GHz working frequency (customized), with a transmission range of 5~10 km, sending high-definition video from a moving vehicle back to a receiving station.

Video comes in over HDMI and is compressed with H.264, giving a high-definition 1080P60 image output that stays clear and stable with no trailing. Full-duplex voice intercom and full-duplex two-way data transmission run alongside the video, so the same link carries voice and sensor data as well as pictures.

At 270*70*25 mm and 600 g (w/battery), with a 4200 mAh battery and DC 12 V power supply, the APEX1707 is small and light enough to mount in a vehicle and carry easily, while AES256-128 encryption keeps the wireless channel secure.

Application Scenarios

1) Vehicle-Mounted Video Transmission

Mounted in a vehicle, the APEX1707 transmits 1080P60 HDMI video over 5~10 km to a receiving station, giving a mobile platform a live high-definition video uplink with clear, stable images and no trailing.

2) Mobile Surveillance and Monitoring

For mobile surveillance work, the transmitter sends live video from the vehicle while its full-duplex voice intercom keeps the crew in contact with other equipment at any time.

3) Vehicle Sensor Data Link

For vehicle-mounted sensor applications, the full-duplex two-way data transmission supports the access of various sensors and data, so one 20 W COFDM link carries video, voice and sensor data together over an AES256-128 encrypted channel.
