Abstract

Disclosed is a method of using local area networks (LANs). Offices using local area networks (LANs) are often confronted with purchasing new technology when re-arranging offices and plans include wireless communication over LANs. The current mode is to replace existing LAN adapter cards with wireless cards thus rendering the old cards useless. Should the need for wireless go away, and a wired LAN connection is desired, the wireless adapter is removed and replaced with a wired one. This invention eliminates the need to remove the old card when adapting workstations to wireless. It will also enable the workstation to become a gateway or bridge between LAN networks or segments.

Interface And Network Personal Computer Adapter Cards

   Disclosed is a method of using local area networks
(LANs).  Offices using local area networks (LANs) are often
confronted with purchasing new technology when re-arranging offices
and plans include wireless communication over LANs.  The current mode
is to replace existing LAN adapter cards with wireless cards thus
rendering the old cards useless.  Should the need for wireless go
away, and a wired LAN connection is desired, the wireless adapter is
removed and replaced with a wired one.  This invention eliminates the
need to remove the old card when adapting workstations to wireless.
It will also enable the workstation to become a gateway or bridge
between LAN networks or segments.

   By incorporating a PCMCIA interface on existing LAN adapter
cards, and including in the driver software the ability to scan for
the presence of a PCMCIA Wireless Adapter, conventional LAN adapter
cards and drivers can be used for wireless connectivity when the need
arises.

   Each LAN type (Ethernet, Token Ring, etc) adapter card
can be modified to include a PCMCIA socket and necessary driver
hardware.  The LAN driver software can scan the slot during boot
time and select the Wireless Device if it exists.  This can be under
software control so that the user can determine if they wish a
wireless or a wired connection.  If a wireless device is in the slot,
the user can select wireless communication to the LAN or the device
may automatically select the wired LAN if one exists for better
performance.  This permits the user to freely move their system from
office to office or to conference rooms for presentations or
demonstrations and not worry a...
