In this paper, to solve the problem of overlapping sensing area and give consideration of the special environment characters of the operating room, a new framework that combines active RFID tags and signal level matrix, SLM, is proposed for the positioning and monitoring of surgical patients in the operating room.
In this paper, we examine the sole use of RSSI or power control approaches as an initial, yet coarse, step to localize active RFID tags. Even though AoA is an attractive localization method, we show that existing AoA estimation methods comprise high error rates due to the phase measurement correlation.
Scavenging ambient Wi-Fi transmission through the rectenna model can be a possible solution to prolong the battery life of the active RFID tag. Wi-Fi networks are becoming more accessible.
Active RFID tags are used to track assets over long-range.
Items being shipped in containers and on pallets are recorded on an active RFID tag, and the tag is placed on the outside of the shipping container or on the pallet.

In order for a self-inventorying SMART Container to be effective, it must consistently read passive and active RFID tags and do it faster and with less human effort than other means.
In Section 2, the research methodology is divided into four parts, namely, (Section 2.1) the principle of electrical power meter; (Section 2.2) the embedded active RFID tag architecture; (Section 2.3) the portable reader architecture; and (Section 2.4) the proposed WSN.
Tens of thousands of transactions between the host and an active RFID tag running BLE can be achieved using a single milliamp hour of battery capacity.
The active RFID tag was used to track the lift truck while the passive RFID tag was used to track the pallet.
However, AIT systems and wide-area networks are being designed to correlate an active RFID tag number with the physical location of the tag, the time the tag was read, and the contents of the container.
