Active RFID
 Active RFID describes wireless identification technologies which incorporates batteries and other power-sources in they tags/transponders. The power source is used both to activate the on-board microchip as well as to transmit more powerfully, resulting in higher read ranges compared to passive RFID technologies. |

Elements of Active RFID
|

|
 |
|
|
Base-Station - Receive the incoming messages from the tags utilizing 1 or more antennas connected to it., process them, and forward to middleware or other software systems via Ethernet, Serial or WiFi connwctivity.
|
Exciter/Beacon- Sends a signal to tags, causing them to "wake-up" and transmit a message. An exciter can be connected to multiple antennas, enabling portal application and detection of tag's direction of movement.
|
Tag- An active RFID tag is usually an electronic circuit assembled inside proper housing. The circuit contains a microchip which is usually far superior o those that can be found in standard passive RFID transponders, large internal memory, a power source (usually a battery) and optional sensors. | |
LogiTag Systems develops and market high-end active-RFID technology, and has already implemented it with many customers. LogiTag's active RFID technology is used as a platform for building market-specific solutions.
