Unlike systems based on passive RFID, Active RFID systems operate with a larger reading range, thanks to the built-in battery transponder increasing its transmission power. Increased range in this case is paid for by shorter operating time and a larger size of the transponder itself, but in some applications this approach is crucial.
The hardware components of the active access control system include the ACTS-2 long-range readers, which connect via RS232/RS485, WIEGAND or 1-Wire interfaces to the control system, which, based on the user rights read from ATPLA-S/N transponders by controlling an electric lock, electric lock or other device such as: turnstile, gate, barrier - it will allow the user to enter/pass the given zone.
The ATPLA-N and ATPLA-S transponders can send their ID cyclically or can be triggered by pressing the button. The operational range is then up to 200m. In addition, the ATPLA-S transponder has the ability to detect the presence of the ACTS-2 reader. The detection range in this case is up to 5m.
The ATPLA-N and ATPLA-S transponders have their own unique IDs up to 4 bytes long and can be programmed by system administrators using the PAC-AU reader and programmer connected to a computer via the USB interface.
An example of such an application can be a system in which the ATPLA-S transponder is located in the vehicle (perhaps permanently) and controls, for example, a garage door or a parking barrier, without maintenance. As with any RFID application, the application possibilities are almost limitless.
