This sounds like the Ericcson Mobidem and the Mobitex packet radio
network.  Motorola also has a similar but incompatible network called Ardis.
Neither of them are cellular telephone systems, they are radio packet
radio systems.  Cellular telephone networks can also be used for the
transmission of data.

Although the HP IR could be used for a network connection, the built-in
software only only runs it at 2400bps and there is no HP IR <-->
ethernet/whatever bridge/router.  The port is mostly used for
transfering data to another HP palmtop, calculator, or IR printer.
Some people have written TCP/IP SLIP software for the HP.  The Fujitsu
Poqet PC has only a conventional option serial port.

More information on various palmtop computers can be gotton
via anonymous ftp from csd4.csd.uwm.edu:/pub/Palmtop.

Here is some information on various data on radio systems:
