1.1.3.1 Wireless System
The wireless system provides the remote access interface. The transmission range of the
wireless system is up to 4 km (2.5 miles), depending on the following factors:
a. Interference (noise) on the selected frequency. The “cleaner” the frequency, the longer
the range.
b. Crop clearance – radio waves do not penetrate foliage very well, especially when wet
from rain or dew.
c. Topographical conditions – the extent of line of sight (LOS) pureness and positioning
height affect the transmission range accordingly.
Base Station Receiver and Antenna
The base station includes the antenna and receiver as a joint unit and is responsible for the
reception of data sent by the transmitters and for its transfer to the PC via RS232 (see
Figure
1-2).
