Application of WIA-PA Network in Underground Staff Positioning System

This paper introduces superiority of WIA-PA in communication and takes MSP430F1611 and CC2520,which can provide hardware function with high quality for underground staff positioning system,as core component of network node.The key is that design has used antenna amplifier CC2591 which can expand the communication coverage range to 200 meters.The design has slove problem,coal mine underground staff functions of a single network location,the bad network capacity and not being located for more than a moving target at the same time,after a coal mine accident can provide a basis for effective relief.It is true that the investigation of WIA-PA is valuable.
