The most common, though not the only frequencies generally available for RFID use are LF (nominally 132 kHz), HF (13.56 MHz), UHF (860 - 960 MHz) and microwave (2.45 GHz and 5.8 GHz). Wireless LAN systems based on the spread spectrum in the 2.4GHz band and 5.8GHz band are widely used throughout the world. In this study, the consideration is about integrating two RFID spectrums together which is 2.4GHz and 5.8GHz in one active tag. The need of using two spectrums is to get the best RTLS.
