Wi-Fi based RFID
Wi-fi based RFID systems use the existing wireless infrastructure of the organisation. Additional readers can be installed where the current system has no or insufficient coverage.
Active RFID Location Tracking
Active radio frequency identification (RFID) technology can be used to track the location of assets or people to increase efficiency and improve safety

How active RFID works
In active RFID systems, assets or people are fitted with a special tag with an internal battery. This transmits a regular radio frequency (RF) signal with a unique ID. Signals are picked up either by an existing wi-fi infrastructure or a network of proprietary readers and then passed on to a central database for tracking and analysis. Alternatively mobile readers can be used. Active RFID tags be read over a distance of up to hundred metres depending on the environment and the asset properties.
Active tags can include sensors in the tag and can be used to track temperature and shock for example during extended logistics processes. They can also make use of the mobile phone network to transmit position and sensor data.
Benefits of active RFID
Active radio frequency identification (RFID) technology is ideal for high-value asset tracking, tracking people and temperature monitoring. Compared to passive RFID it provides longer read ranges and the option to record additional information such as temperature information or emergency call signals.
Active RFID systems are characterised by the way they communicate with a central database:
Non Wi-Fi based RFID
Non Wi-Fi based RFID systems use a network of fixed RF readers placed strategically to detect tags and update inventory location records. Handheld mobile readers can be used in addition for areas where there are no fixed readers.
Bluetooth Low Energy RFID
Bluetooth Low Energy (BLE) RFID tags utilise an industry standard to send out transmissions to a mesh of nodes. By detecting the signal, the system can calculate the location of the tag.
