Possible impairment of radio transmission

Collisions when using an excessive number of probes

When using a large number of probes, do not select a transmission interval which is too low,
otherwise the radio channel will be unnecessarily occupied. A too low transmission interval
means a very high data volume on the selected frequency which can lead to collisions with oth-
er probes. Telegrams can be destroyed during radio transmission caused by collisions.

The telegrams of a probe reach the receiver without collisions.

Telegrams of several probes can collide.
