RFID frequencies
Ultra High Frequency (UHF) tags operate at 865-868 MHz (in Europe). They are low cost and available in a wide range of form factors, including small, thin, flexible ‘smart labels’. With read ranges of up to 10 m and a wide feature set, they are ideally suited to supply chain and logistics applications where large numbers of tags will be present. They are, however, generally susceptible to water and metal in close proximity.
Selecting the most appropriate frequency for an application will depend on many factors. Obvious considerations include: read/write range; cost; and memory features, together with more challenging considerations, such as environmental effects and the influence of nearby materials.
To help unleash the full power of RFID, it is important to work with a partner who has both the expertise and experience required to ensure tags operate reliably and effectively – particularly in the harsh environments often encountered in industrial applications. |
