Features of the 2.4 GHz remote controls
GB
The transmitter technology at 2.4 GHz is
fundamentally different in some aspects from the
technology in the 27, 35 and 40 MHz frequency
ranges, which up to now have been conventional
with remote control models. The previous style of
location using a channel determined by plug-in
crystals is gone, and the transmitter and receiver
work with encoding. The receiver accepts only
signals with the coding from its own transmitter.
Each signal from the transmitter lasts just
milliseconds.

Advantages of the 2.4 GHZ technology

Although the frequency range used is also divided
into channels, the user doesn't have to worry
about their configuration and has no influence on it
anyway.
Because the same encoding is used by the
transmitter and receiver, interruption by another
receiver or a different transmitter will not occur.
Plug-in crystals are not needed, because the
transmitter creates the currently appropriate
frequency using a synthesizer circuit, as does the
receiver, which determines the right frequency for
ist encoding.
Worth noting
At very low wavelengths, obstacles can weaken or
interrupt the spread of radio waves. That means
there should be as few obstacles as possible in
the line between the transmission and reception
antennas. The model's receiver antenna must be

Before the next signal, a pause is inserted, which
lasts longer than the transmission signal.
Nonetheless, within each second countless signals
are received and evaluated by the receiver.
Signals that the receiver recognizes as defective
(false encoding, strings that don't fit the signal
schema, etc.) are suppressed and are not passed
on as control commands.
And as the frequency gets higher, the antennas
get shorter.
Remote controls using this transmitter technology
or model construction are not subject to fees.
The old fear of double occupancy of a channel (as
when a second transmitter overreaches and
interrupts a receiver) is a thing of the past. An
operator can go ahead and switch on a transmitter
and receiver, without negotiating with other model
users.
The data transfer capacity is considerably larger
than that of previous remote controls, which has a
positive effect on control of the digital servo, for
example.
Best of all, at events with a lot of participants, you
can always use your own equipment for settings,
tests and conversions, because the number of
active transmitters is almost unlimited.
