The WLAN explosion is resulting in a proliferation of enterprise WLAN networks beyond the existing LAN networks. Concurrently with the growth of VoIP (Voice over IP) traffic on enterprise LAN networks, interconnection of those networks is occurring.
Interconnection of enterprise LANs enables the completion of VoIP calls from one enterprise to another, without passing through the PSTN.
With the addition of WLAN devices to the enterprise LAN network, the potential exists for the WLAN devices to roam to other enterprise WLAN networks while maintaining connectivity to their home enterprise network.
This enables, when security and other elements are addressed, roaming of WLAN devices from one enterprise network to another. For example, when a WLAN user from company A is meeting with company B, it is desirable to provide the visitor with access to their home enterprise WLAN. That would enable voice and other communications to easily reach the user, even though the meeting room may be within the building and not accessible by cellular signals.
Another scenario would be the provision of WLAN (and other inter-enterprise roaming) on a reciprocal basis, with a clearinghouse maintaining records to ensure that a reasonable balance among the roaming users is maintained.
