Įvadas

1. This Individual Soldier Manpack COFDM Mobile Wireless Video Real-time Transmission System is a backpack wireless video transmitter and two-way voice intercom.
2. It has relatively narrow-band air frequency occupancy (2/3/4/5/6/7/8M) and strong anti-multipath interference ability
3. Using the current leading COFDM modulation technology, combined with foreign advanced diversity reception technology to overcome.
4. In the case of non-line-of-sight (be regėjimo linijos), 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.
5. 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.
6. 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 (kelių nešiklių moduliavimo technologija), the core technology of third-generation mobile communication, and H.264 video coding technology.
7. 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.

ypatybė

1. Design that is highly integrated, modular, and combined
2. H.264 image compression technology uses COFDM modulation technology.
3. All-around communication, no fear of building and wall obstruction
4. Travel communication at high speeds, heat sink type aluminum case, shockproof and impact resistant
5. Ne Line-of-sight (NLOS) mobiliojo ryšio perdavimas, where the distance under normal conditions is at least 20 kilometrų. The maximum moving speed is 600km/hour
