RFID

RFID lpraRFID systems operate in several licence exempt frequency bands, co-existing with other low power devices.
Typical applications include access control, mass transportation, logistics and security.


RFID mainly operates in 5 different frequency bands. These are inductive (< 135 kHz), HF (13.56 MHz), VHF (433 MHz), UHF (865 - 868 MHz) and 2.45 GHz. The properties of radio waves varies across the radio spectrum. The choice of frequency selected by the end user is heavily dependent on the application.

Radio Frequency IDentification is a rapidly developing sector of the SRD industry. Radio tags which contain an identity number and sometimes additional data are attached to animals or objects that are to be identified. When the tags are brought within range of an interrogator, the tags are activated and transmit their identity.

The RFID group maintains a close interest in European regulatory developments in so far as they effect the industry.

Update on EN 302 208

RFID manufacturers and system integrators with equipment operating at UHF should familiarise themselves with two developments concerning the ETSI standard EN 302 208. Read more >>
