“…The technology is realized by two components, which are the mobile RFID tag as the transmitter and four units of low power data radio modules, (LPDRM) as the RFID readers. In [2,[11][12][13][14][15][16][17], RSSI is a parameter that has been used in predicting the location of a wireless device and estimating the distance traveled by a transmitted signal to reach the receiver. Instead of using complicated localization algorithm such as MUSIC algorithm [17], the mobility of the RFID tag and the 'pyramid' structure of the RFID readers' antenna which has four sections with leaned at 45 • angle for every single section enable the proposed system to perform the same function efficiently as an easier approach.…”

Abstract-A form of a novel adaptive antenna system that combines radio frequency identification (RFID) technology, programmable intelligent computer (PIC) microcontroller and reconfigurable beam steering antenna is proposed. Localization and adaptive response are the most challenging issues in smart antenna system. In this research, the localization technique relying on the received signal strength (RSS) signals has been done intensively where the capability of the RFID tag in producing certain level of signal strength has been exploited as a

“…In [15,[17][18][19][20][21][22], received signal strength indicator (RSSI) is a parameter that has been used in predicting the location of wireless device in Wi-Fi positioning systems. To the authors' knowledge, none of these designs has demonstrated an adaptive Wi-Fi system using a combination of RFID technology with reconfigurable beam shape antenna controlled by PIC microcontroller.…”

A novel adaptive Wireless-Fidelity (Wi-Fi) system is the combination of radio frequency identification (RFID) technology, programmable intelligent microcontroller development board (PIDB) and reconfigurable antenna with beam shape characteristics. The system is capable to sustain a Wi-Fi signal adaptively above its threshold level (−81 dBm) within a range up to 100 m across three different buildings with variety indoor environments and floors. It is found that the modified ground reflection model has successfully predicted the total path loss of the test-bay buildings which consist of corridors, several floors and windows. The modified propagation model is extremely crucial in determining the projection and height of
