Wireless local area network with clients having extended freedom of movement
First Claim
1. A network with wireless access capability comprising:
- a plurality of wireless access points;
at least one Ethernet aggregation switch, ones of said plurality of access points being connected to each said at least one Ethernet aggregation switch, each said Ethernet aggregation switch being virtual LAN (VLAN) aware and matching client traffic from connected said access points with access VLANs;
a free-form virtual network switch passing client traffic between said access VLANs at each said connected Ethernet aggregation switch and appropriate core VLANs; and
at least one tunnel endpoint connecting an other wireless network to said freeform virtual network switch.

Abstract
A wireless virtual local area network (VLAN) and a device selectively connecting to the wireless VLAN over a second wireless network that may be independent of the wireless VLAN. The device is capable of connecting to at least the wireless VLAN and to the second wireless network. Wireless VLAN access points are each connected to an Ethernet aggregation switch, which is VLAN aware and matches client traffic from connected access points with access VLANs. A wireless VLAN switch maintains an association table between access VLANs and core VLANs. The second wireless network may be remotely connected over the Internet or a private network to a tunnel endpoint. The tunnel endpoint is connected to the VLAN switch, which uses the association table to manage free-form client traffic between connected devices and other mobile stations at access VLANs and appropriate core VLANs.

15. A network with wireless access capability comprising:
-
a plurality of wireless access points;
a plurality of mobile stations wirelessly connectable to said plurality of access points, at least one mobile station connectable to at least one other wireless network;
Ethernet aggregation means for connecting ones of said plurality of access points to said network, said Ethernet aggregation means being virtual LAN (VLAN) aware and matching client traffic from said plurality of access points with access VLANs;
free-form virtual network switching means for switching client traffic between said access VLANs at said Ethernet aggregation means to appropriate core VLANs; and
tunnel endpoint means for terminating Ethernet packets tunneling over other wireless networks and providing terminated said Ethernet packets as client traffic to said free-form virtual network switching means, said tunnel endpoint means providing a MAC address proxy for connected ones of said at least one mobile station, said freeform virtual network switching means switching client traffic from said tunnel endpoint means to appropriate core VLANs. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
