Abstract – Today, mobility of portable computers and workstations is not transparent to users. They adjust to reduced services as long as they have no connection to a supporting infrastructure. The goal of the Walkstation project is to realize a user transparent mobile IP router (MINT) for wireless links (infrared and radio) operating at 1-10 Mbit/sec. For the study of user behavior and system characteristics a campus wide testbed (ERIC) with 50-100 stations is planned to demonstrate the new solutions found in the Walkstation II project.

1. INTRODUCTION New technologies have paved the way for portable computers operating at low power levels with extended battery duration. Computer manufacturers now offer portables using 3.3 Volt techniques, LCD displays and pen interfaces [11]. The AT&T Personal Communicator [12] is a first step towards a small sized personal communication device combining computation and communication. Still users have to face the fact that even if they have sufficient computational power in their hands they have insufficient communication capabilities. Applications requiring mobile and wireless communication channels suffer from the low bandwidth offered (
