Transmission Range
The main factors that influence the system transmission range are:
Type and location of the antennas of receiver and transmitter
Type of terrain and degree of obstruction of the link path
Sources of interference affecting the receiver
“Dead” spots caused by signal reflections from nearby conductive objects
Since the expected transmission range strongly depends on these system conditions, range
tests should categorically be performed in early project phases!
The following figures for expected transmission range are considered by using the PTM
240C radio transmitter module and the TCM2xyC radio transceiver module with mounted
whip antenna and may be used as a rough guide only:
10 m
in industrial applications with metal in the vicinity
30 m
for obstructed environment (e.g., through two brick walls inside a building)
200 m
for unobstructed environment (“free field”)
Further notes to determine the transmission range within buildings are available as down-
load from
