ENVIRONMENTAL CONSIDERATIONS

7.1

General

Microwaves have, during more than a decade, proven to be the most reliable technology for
identification systems. In particular, microwaves are unaffected by the normal electromagnetic
background noise found in industries and elsewhere. They also form a base for products that
have to withstand other rough environmental conditions as high temperatures, chemicals, shock
and vibrations
7.2

Electromagnetic immunity

The TagMaster system has been tested and approved, in operation, according to the IEC
standards. This guarantees trouble-free operation in demanding electromagnetic environments.
Electromagnetic interference on the microwave link
Industrial noise is typically present in the KHz and low MHz frequency band. The TagMaster
system is only receptive for frequencies closed to 2.45 GHz so typical industrial noise will not
affect the microwave communication. Transients from spot-welding equipment or from
switching on other welding equipment, soldering machines and fluorescent lamps may produce
short pulses around 2.45 GHz. However, since the TagMaster system, if interfered, will
retransmit the entire message very fast there is in most cases ample time for a re-transmission. If
strong microwave fields, from for instance microwave dryers, can be suspected, TagMaster AB
should be consulted.
Electromagnetic interference in cables
By selecting a suitable communications interface, using specified cables and proper shielding
and grounding, optimum communication reliability is ensured.
