System introduction MK-917 system,made by Guilin mingke communication equipment Co.,Ltd,is essentially different from wireless bridge or non line of sight mobile IP transceiver system on the principle of COFDM, and adopts advanced modem technology, Channel codec and unique error correction coding techniques. It can transfer HD images in real time based on UDP/TCP/IP in the high-speed mobile and extremely complex environment. Solves the problems, such as complex terrain, shelter from buildings,and so on,it can offer a perfect IP interface network platform for special and field operations and. Technical Features 1.Adopted ADTB technology with high spectrum efficiency, robust to multi-path interference and application of broadband signal transmission, compared with network bridge and COFDM technology, it is an innovative technology of time-domain and frequency-domain. 2.Supporting mutiple modulation. Receiving threshold reaches -99dB under low oder modulation. Even under bad condition with 1.7 carrier-to-noise ratio, the machine also can receive demodulation normally. That means the transmission can keep on under extremely complex environment.
