100km airborne wireless broadband communication video transmission system transmitter-receiver

Introduction

Description

• This product is a wireless high-definition video transmission module designed specifically for UAV communication.
• The latest generation of wireless video communication equipment was independently developed and designed on the basis of integrating the latest terrestrial digital TV technology.
• Its core in the field of wireless communication is advanced LDPC error correction code technology, AES128-bit encryption, and zero-IF modulation technology.
• It is capable of transmitting high-speed real-time video data in “high-speed motion” and “non-line-of-sight conditions.”
• This product is small in size and light in weight.
• It has a beautiful and reasonable structure design and excellent radio frequency performance.
• A long transmission distance, theoretical (test) distance up to 200km (known practical application distance of 140km), low power consumption, and long battery life, make it an excellent choice for drone communication.

Advantage

• Advanced: capable of high-speed movement, long-distance travel, anti-interference, and spectrum resource conservation
  • To reduce local noise, the wireless receiving module uses zero intermediate frequency demodulation, multi-carrier TDD-COFDM (time-domain synchronous orthogonal frequency division multiplexing), and the same frequency noise reduction algorithm processing technology as the wireless transmitting module. Video images are transmitted in 1080P-60 frames, conserving spectrum resources.
• The communication system that is energy-efficient, environmentally friendly, and spectrum-compatible:
  • The wireless transmission core of the system has a very high peak-to-average ratio on the modulator, and the radio frequency transmission processing uses pre-distortion processing technology. The overall power consumption of the equipment exceeds 30% efficiency, which is significantly higher than the 16% equipment power consumption of the traditional one-way COFDM system. The RF filter employs a multi-stage band-pass filter, which has the excellent out-of-band rejection of RF power output and spectrum compatibility.
• Highly reliable, safe, and secure communication system (the system adopts private communication transmission protocol, private synchronization code, and AES encryption)
  • AES 128-bit encryption technology: After AES has encrypted the information data, the information before encryption cannot be obtained;
  • Encryption of synchronization code: A 256-bit synchronization code is used for signal timing, carrier synchronization, and frame synchronization; the phase change method of synchronization code employs encryption.

FAQ

Q1: This product looks large and heavy. Are you sure it can be used on drones?

This product simply adds a sturdy, waterproof case with four screw holes for the tripod to the transmitter and receiver; if you need to mount it on the drone as a transmitter, you can remove the large case to save weight. As the receiver side, the case is suggested to be kept. https://ivcan.com/p/uav-drone-video-data-link-module-wireless-transmitter/
