Introduction
During the last years, the wireless communication has increased very much. In general this does
not influence the data communication of the DE212. However the expansion of the 4G network
has given several new Base stations to improve the 4G service for travellers entering or leaving
the aircrafts at the gates.
These 4G Base stations operates at a different frequency than the DE212, but at short range the
much higher power can disturb the receiver input so much that the operation stability is reduced.
In order to solve this challenge, Delta RC has done research and several tests at busy airports and
have introduced at the DE212 #03040 system:
a) A more selective 2,4GHz receiver module. Integrated in the receiver unit.
b) A new and more selective standard antenna on top of the receiver
c) A new and more selective antenna for external installation
d) A new sector antenna solution for extreme and heavy radio disturbances.
With this solutions, Delta RC has found a safe and practical way to deal with disturbing radio
signals.
In most cases, the solution a) will solve the disturbance problem and is standard for the 03040
model.
In cases where the base station is very close to the gate, 100 to 300m the sector antenna solution
may be needed.
Also note that the disturbance problem is not a static situation. The wireless network is constantly
expanded or changed. However the new development with 5G is not expected to cause problems.
The reason is that new network normally are at higher frequencies than the 2,4GHz.
