Li Wei · Computer Technology and Development · 2011
At present,people 's demand for the indoor positioning and navigation is getting greater and greater.For example,in some indoor places like exhibition hall,library,torehouse,upermarket,ustomers expect to make use of the equipment for free indoor positioning and navigation.Thus,the purpose of this paper is to introduce the working principle,advantage and disadvantage of Cricket location system based on ultrasonic technology and RFID technology.The way of the improvement of this system has also been brought up.By the way of introducing energy-saving system,allotment of signal channel of Cricket location system will be improved and get the result of the energy consumption and the cost of Cricket positioning system,which will finally reduce the energy consumption and the cost of Cricket indoor positioning system and make sure of the equality among the node.
