Adapters or laptops with 7400 PC cards, are set to the same
Domain and Security ID as the Access Points. As the
RangeLAN2 mobile clients seamlessly switch from cell to cell,
the network connectivity is preserved.
The user can move freely between the RangeLAN2 Access
Points in the network. When the roaming unit leaves the trans-
mission range of one RangeLAN2 Access Point, the software
automatically polls the other RangeLAN2 Access Point in the
same Domain to continue the network connection.
Note that the cells must overlap to ensure that there are no gaps
in coverage, and that the roaming PC will always have a connec-
tion available.
The RangeLAN2 Ethernet Adapter allows you to add printers,
computers in locations which are difficult to wire, and other
Ethernet-ready devices to the wired LAN by synchronizing to a
RangeLAN2 Access Point connected to the wired backbone.
Note:
If the Ethernet Adapter roams between Access Points
on the same network, then each Access Point must
have the “Filter Fixed Nodes” parameter set to “Not
Filtering.” However, this does not apply to RangeLAN2
Ethernet Access Points with revision 1.4 or greater of
the Access Point flash code image installed. Please
refer to Chapter 11 for details.
