Introdução
- This Individual Soldier Manpack COFDM Mobile Wireless Video Real-time Transmission System is a backpack wireless video transmitter and two-way voice intercom.
- It has relatively narrow-band air frequency occupancy (2/3/4/5/6/7/8M) and strong anti-multipath interference ability
- Using the current leading COFDM modulation technology, combined with foreign advanced diversity reception technology to overcome.
- In the case of non-line-of-sight (sem linha de visão), the difficulties caused by multipath reflection and occlusion in image transmission under analog technology and conventional modulation technology can be realized by shooting and real-time transmission of high-quality images in high-speed motion.
- The device works in conjunction with a single Soldier backpack that contains a large-capacity lithium battery, can be operated by a single person and is frequently used for short-distance wireless video transmission and from the air to the ground mid-to-long-distance wireless image transmission.
-
It can transmit real-time and stable 1080P high-definition audio and video signals during high-speed movement and under the occlusion of urban buildings by utilizing COFDM (tecnologia de modulação multi-portadora), the core technology of third-generation mobile communication, and H.264 video coding technology.
-
Multiple devices can be sent to a mobile command vehicle at the same time, and the command vehicle can then transmit the data to the command center.
Característica
- Design that is highly integrated, modular, and combined
- H.264 image compression technology uses COFDM modulation technology.
- All-around communication, no fear of building and wall obstruction
- Travel communication at high speeds, heat sink type aluminum case, shockproof and impact resistant
- Non-line-of-sight (NLOS) transmissão móvel, where the distance under normal conditions is at least 20 quilômetros. The maximum moving speed is 600km/hour
