Does RTLS use RFID?

While RTLS has two parts to it, so does RFID technology. With active RFID, a signal is sent to a reader every few seconds and location is calculated using different methods, such as triangulation. With passive RFID, there are special reading devices and the technology works in approximation to them.

Where are active RFID tags used?

Active RFID transponders are commonly used in secure access control and in toll booth payment systems. Beacons – In a system that uses an active beacon tag, the tag will not wait to hear the reader’s signal. Instead, true to its name, the tag will ‘beacon’, or send out its specific information every 3 – 5 seconds.

Can you track someone with RFID?

An Active RFID system can be implemented quickly enabling you to track people in locations that you would have needed expensive GPS devices in the past. With Active RFID, you can track people anywhere as they move freely without the need for portal technology.

How active RFID tags work?

Active RFID tags have a transmitter and their own power source (typically a battery). The power source is used to run the microchip’s circuitry and to broadcast a signal to a reader (the way a cell phone transmits signals to a base station).

What kind of RFID tags are used for RTLS?

Active UHF RFID is typically used for RTLS in large, outdoor environments. Depending on the setup, active RFID can have a large read range of hundreds of meters. Instead of waiting for the reader to send a signal to power the tags like Passive RFID, Active RFID tags contain a battery to enable continuous signal broadcasting.

What can RTLS be used for in real time?

RTLS solutions will often be developed to include single, dedicated Active Radio Frequency Identification (RFID) infrastructure that can expand and support a wide variety of applications – including real-time location and tracking, security, access control and flow control – and withstand a range of environments and environmental conditions.

Why do people wear RFID tags at all times?

By wearing active RFID tags, including those with discrete push buttons, unparalleled protection can be given to staff and patients at all times. RTLS solutions can provide greater efficiencies when it comes to knowing where your assets are and what your people are doing.

What’s the latest form factor for RTLS tags?

The latest form factor, the SmartBadge is a full feature, active RTLS tag designed in the shape of a typical staff I.D. badge. The tag is equipped with two buttons that can be pressed to initiate a variety of alerts and notifications through third party software applications.
