[net.micro] Info on radio-link modems wanted

spoo@utcsrgv.UUCP (Suk Lee) (04/18/84)

I have a friend who is interested in
some sort of radio-link system in which
people could roam around a fairly large
building with portable terminals and
access a central database.  

I seem to recall hearing at some point
about standard RS-232 modems that used
a radio link to a standard telephone,
or something of that ilk.  Is this a
rhira-dream, or does anybody have
information on this?  Any and all
responses appreciated.  Please respond
by mail to:

This isn't exactly what you were asking for, but:

I have an old Motorola ad (1978) for "The RDX Portable Data
Terminal System." The unit looks like a special keypad/ bar code reader
stuck to one of their UHF handitalkies. The radio could send/receive
at a rate of 80 characters per second. The control unit at the
base station would be connected to leased lines at rates of 1200
to 9600 bits per second.

The big problem, as far as I was concerned, was that the other
end of the leased lines was supposed to be connected to an IBM 360/370.
Also, if I recall correctly, a Motorola handitalky by itself is
in the kilo-buck range.

I have no idea whether this is still being marketed.
