RS232 Multiple wireless IP network RJ45 long range TDD video transmitter receiver


Multiple wireless IP network RJ45 TDD video transmitter receiver long range



TDD video transmitter receiver Introduction:


The full-duplex communication device is a TDD terminal equipment which can connect with IP camera. It is using TDD bidirectional network transmission technology, integration of the latest LTE mobile communications and terrestrial digital TV TDS technology. T321 is our independent patent design with multi-access wireless communication technology. Adopt the multi-user wireless communication field’s the most advanced Coding, TDD-OFDM, LDPC error correction code, DPD, H.264 codec and other technologies as the core, the allocation of channel resources through the time slot control, the frequency through the sub-carrier to be flexibly assigned to multiple user terminals, to achieve the maximum number of end-user multiple access under same frequency. Realize real-time, full-duplex information transmission under the non-line-of-sigh, high-speed movement conditions. Multiple wireless networks can be integrated with each other layout network coverage.


Volume is 220 * 128 * 54mm (with battery), 3 km non-line of sight transmission range , 6 km line of sight range, 8 km air to ground transmission, battery can work constantly up to 5 hours, high-definition stable video quality, support voice calls and high-speed mobile transmission stability.
