Introduction

The most compelling reason to virtualize APs has been security. There are currently two possible techniques for doing this, though only one has been deployed in the wild. The most prevalent has been implemented by Colubris in their virtual access point technology [4].

The other technique, public access point (PAP) and personal virtual bridged LANs (PVLANs), which is described in this paper, has been documented in U.S. patent no. 20040141617[1].
