Long range monitoring Full Duplex wireless transmission TDD-OFDM Base Station
TDD-OFDM Base Station Introduction:
The system adopts TDD bidirectional network transmission technology to integrate the latest LTE mobile communication and terrestrial digital TV TDS technology. This is our independent patent design system with multiple access wireless communication technology, using the current multi-user wireless communications ‘s most advanced coding modulation, TDD-OFDM, LDPC error correction code, DPD, H.264 codec and other technologies as the core, the channel resource allocation through the time slot control, the frequency through the sub-carrier to be flexibly assigned to multiple user terminals. The maximum number of end users to achieve multiple access, to achieve real-time two-way transparent information transmission under the non-line-of-sight, high-speed movement conditions. Multiple wireless networks can be integrated with each other layout network coverage.
The weight is less than 10kg, 424 * 366 * 198 cm, box body with a wheel, 8 road D1 video or 4 road 720p decoding, 4 users realize two-way transmission at the same time, 14-inch high-definition display, 128-bit AES encryption, built-in amplifier, ; Flexible power supply, single battery can works constantly more than 3 hours.
TDD-OFDM Base Station Product Features:
1. Strong diffraction ability, support two-way communication under single frequency.
2. Covering a wide range of flexible allocation of channel resources, to achieve point to point, point to multipoint, multi-point to multi-point two-way communication.
3. Strong error correction capability, using the most advanced LDPC error correction code technology, QPSK mode carrier-to-noise ratio threshold of 0.5dB, approaching the theoretical limit of communication
4. Strong anti-fading performance, with anti-long delay and strong multipath ability, more suitable for urban environment.
5. Support 8-channels video decoding , Built-in soft matrix , data storage.
6. A single carrier frequency support within 4 users ' video, audio, data and other multimedia information, high-speed, real-time, synchronous transmission.
7. Built-in voice intercommunication device , and PTZ Control , easy operation.
