Currently there is a lot of discussion about using an app on your mobile phone, which uses Bluetooth to track who you have been in the vicinity of. When later it is found that you are infected with Covid-19 the data in the app can be used to warn those people that you have had contact with. In the Dutch press [Corona App might fail] ( https://fd.nl/ondernemen/1341169/corona-app-dreigt-te-mislukken-door-haast-kabinet ) in the FD, of Be critical of a Corona App on NU.nl. Internationally this is also being discussed.

Real-time locating systems (RTLS) are used to follow and track people or objects through time. RTLS are frequently employed within a pre-defined area or indoors. As opposed to GPS (which is available world-wide but not indoors) RTLS requires receivers at fixed, reference locations to be able to determine the exact location of a person or object.

A wireless RTLS transponder is attached to the person or object. In most RTLS systems the fixed receivers in known locations are used to determine the exact location of the object. Depending on the size of the area to be covered and the required precision of localisation a number of different technical approaches are possible. These also vary in the number of receivers required.

You own assets that you’d like to keep track of. Your products in your factory. Valuable stock. Tools in the vans of your technicians. Articles in your warehouse, distribution centers or stores.

Life-saving equipment in a fire engine. Or the right equipment and tools in the operation room in a hospital. Samples in a laboratory.

Or your people. Personnel on an offshore oil-rig. Passengers on a ship. Firefighters in a burning building. Soldiers on a mission.

Have you got difficulty reading your UHF RFID tags over a long distance? With the use of Yagi antennas and a high quality RFID reader such as the Impinj Speedway Revolution, the Zebra FX9500 or the TSS Gold Reader EasyLogic has demonstrated read ranges of over 20 meters, even when using on-metal tags.

The optimal use for the antenna is in a long, pencil shaped range. So these antennas can be used for instance across a loading bay or cross docking facility, able to detect tags on containers before they are loaded into a truck.
