Wireless internet access of the Kista - IT University (KTH) network began in October 1999 as a research project in the Telecommunication Systems Lab (TSLab) at the former Department of Teleinformatics (Sweden).

The main research objective was to study the possibility of adopting wireless access as part of the IT University network infrastructure and to evaluate the level of security required by networks of this kind.

Based on our previous experience running smaller scale wireless networks, a new innovative networking environment was conceived to o˙er Internet access for the two hundred students and researchers of the IT-University study programme. Each student or researcher uses an IEEE 802.11b compliant PCMCIA card to get wireless connectivity using a set of access points available in three different buildings and common areas. Mobility is supported between the radio cells using link level handover or MobileIPv4 to roam between IP networks.

The wireless access allows students to attend lectures with their laptops, take notes and see online documentation while their mail arrives in their laptop mailboxes.

The following paper presents our experience building this network at KTH, as well as our confrontation and investigation of a serious challenge that this open, mobile and wireless net 'space'presents: location privacy.
