High-level interference is caused by nearby products sharing the same
frequency or from near-band high-power devices. It can even come from
your own products if more than one transmitter is active in the same area. It
is important to remember that only one transmitter at a time can occupy a
frequency, regardless of the coding of the transmitted signal. This type of
interference is less common than those mentioned previously, but in severe
cases it can prevent all useful function of the affected device.
Although technically it is not interference, multipath is also a factor to be
understood. Multipath is a term used to refer to the signal cancellation
effects that occur when RF waves arrive at the receiver in different phase
relationships. This effect is a particularly significant factor in interior
environments where objects provide many different signal reflection paths.
Multipath cancellation results in lowered signal levels at the receiver and,
thus, shorter useful distances for the link.
Typical Applications
Figure 16 shows a circuit using the Linx LICAL-DEC-MS001 decoder. This
chip works with the LICAL-ENC-MS001 encoder to provide simple remote
control capabilities. The decoder will detect the transmission from the en-
coder, check for errors, and if everything is correct, the encoder’s inputs will
be replicated on the decoder’s outputs. This makes sending key presses
very easy.
