Abstract

This article describes a technique which would allow wireless communication between terminals and their controller. The wireless medium is not important here; it may be RF, infrared light, data on AC power lines, or any other "wireless" technology. This concept allows wireless communication to be accomplished without any changes to the hardware or software in the operating system.

Wireless Hardware On Local Area Network

      This article describes a technique which would allow
wireless communication between terminals and their controller.  The
wireless medium is not important here; it may be RF, infrared light,
data on AC power lines, or any other "wireless" technology.  This
concept allows wireless communication to be accomplished without any
changes to the hardware or software in the operating system.

      The following describes how one or more wireless units can be
plugged directly in the regular LAN.  These "main-LAN wireless units"
will transfer data between the LAN and remote wireless units.  The
remote wireless units will be attached to remote LANs or "mini-LANs"
which have one or more terminals attached.  The remote wireless unit
will be called the mini-LAN wireless unit.  The mini-LAN wireless
units transfer the data between the wireless media and their
associated mini- LAN.

      Each main-LAN wireless unit will make the controller "think"
that it is one of many terminals that are attached to the main-LAN.
The terminals that the main-LAN wireless unit emulate are actually
attached to the remote mini-LANs. The main-LAN wireless unit must
handle wireless traffic from multiple mini-LAN wireless units.

      The mini-LAN wireless unit will "talk" LAN protocol and make
the terminals "think" that they are connected to their controller via
the main-LAN.

      The attachment of the wireless hardware will not require any
software or hardware changes to the operating system.

      The same model wireless units will function as either a
main-LAN wireless unit or a mini-LAN wireless unit.  The wireless
unit will determine what mode of operation to assume by interpreting
signals on the LANs.

      The mini-LAN wireless units can keep track of which terminals
are on its mini-LAN.  This information can be determined from signa...
