The
LMT2
transmitter
and
LMR2
receiver
modules offer a multi channel, low power, and
reliable data link. This makes the LMT2/LMR2
pair
ideally
suited
to
those
low
power
applications where existing wideband modules
have insufficient range, or where low cost multi-
channel
operation
is
needed
without
compromising on RF specification or regulatory
requirement.
