Abstract: An environment analysis system for indoor wireless location by using locations of a plurality of access points (AP) includes, a first environment analysis tool (10) for receiving indoor environment information for indoor wireless location, performing a simulation for calculating location accuracies, performing a simulation for relocating and/or additionally installing the access points (AP), and displaying results of the simulation; and a second environment analysis tool (20) for receiving wireless communications signals from the access points (AP), calculating distances from the second environment analysis tool (20) to the access points (AP), calculating a location of the second environment analysis tool (20), calculating errors in the distances and in the location calculated, and providing the errors calculated to the first environment analysis tool (10). The first environment analysis tool (10) corrects errors in the simulations performed thereby by using the errors received from the second environment analysis tool (20), and then repeats the simulations and the displaying process.

Abstract: PURPOSE: A device and a method for vehicle location sensing with an RFID are provided to exactly detect the position of the vehicle by communicating data between the RF reader and a tag. CONSTITUTION: An RFID tag(200) transmits a tag signal and is arranged in the driving path of the vehicles. A transmitting antenna(110) transmits a transmission signal for sensing the RFID tag. A receiving antenna(120) receives he tag signal from the RFID tag. An RFID reader(100) detects the location of the vehicles by using tag information. The transmission antenna is arranged in the front wheel of the vehicles and the receiving antenna is arranged in the rear wheel.
