Abstract
In this paper, the frequencies sharing possibility between TA(TalkAround) Radios and RFID system in 900MHz frequency band have been studied. The modulation technic for FHSS(Frequency Hopping Spread Spectrum) of TA is digital FSK and RFID system adapts digital ASK modulation technic. The communication mode of the tested RFID system for frequencies sharing possibility was FHSS. The field test was performed by five scenarios. The RFID field testing system for the frequencies sharing possibility was composed of four tags and two main devices made in USA. Four TA and Egilant spectrum analyzer was used for testing. The frequencies sharing possibility by differentiated modulation was theoretically analyzed. As result of simulation, it was proved that the frequencies sharing between each other modulation system is possible. And also as result of field testing it was confirmed that the signal of TA Radios have no effect on the signal of RFID system.
