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.

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.
