In this paper we examine a high speed wireless access network and present traffic patterns and on-line behavior for wireless users. To date, wireless network studies have largely focused on cellular voice technologies and architectures. Here we present an analysis of data collected from an authenticated campus area access network providing both wireless 802.11b and walk-up Ethernet capabilities through an authenticated access network service. We present an analysis of session data, transport layer flow data, and movement data taken from 109 wireless access points spread across 18 buildings. Local area wireless network (LAWN) wireless services support about 444 wireless hosts, 765 current users, and have sustained more than a million TCP flows over the nearly two month collection period.
