Operating range
The operating distance depends on several conditions, which depend on the actual location.
Most important factors are: The height of the antenna over ground, electromagnetical noise near the receiver
(from PC’s, monitors etc.), other radio transmitters, type of ground, transmitters within the same frequency
band, transmitting on adjacent channels.
If you look for a maximum in operating distance, we recommend the 433 MHz frequency band. If at the place
of use there are other systems using the same frequency band, the 868MHz system may reach a better
operating distance in this case.
With the 433MHz Evalkit3 under normal conditions, operating distances in excess of 4km were measured in
the countryside. The above given distances therefore are rather conservative values.
