Analysis the problems of the current mine wireless rescue communication system.Design and implementation of a MIMO-based wireless technology for portable mine emergency rescue communications repeater,the wireless repeater uses spatial multiplexing MIMO and smart antenna technology effectively reducing the effects of multipath fading.Test results show that the transmission distance far more than the current mine wireless rescue communication system's repeater which based on SISO,and has greatly improved performance on network communication.
