8.2 Special Instructions for Using a Read / Write System

To transfer the data to the transponder or to control the selective read process, all standard

transponder types uses a 100%-pulse-gap-modulation technique.

The modulation of the magnetic field comming from the transponder and the write pattern do-

ne by the base station, shows a lot of similarities. Therefore, read write systems may interfere

each other.

The minimum distance between two antennas mounted next to each other and the size of the

interference must be determined for each application itself.

Below there are listed several parameters that will influence the size of the interaction:

• size of the antennas

• orientation of the antennas (f.e. parallel or rectangular to each other)

• size of transponder; distance between transponder and antenna

• the chronological orders for reading or writing.
