Wireless Internet access based on wireless LAN or Bluetooth networks will become popular within the next few years. New services will be offered using location and personal profiles to filter Internet access. Moreover, "Push" services will allow unsolicited event-based information transfer depending on user configurations. We have introduced such services as "The Mobile Fairguide" during CeBIT 2001 in a Bluetooth network that covered a full hall of 25,000 m2 with 130 base stations. We were able to show that Bluetooth is a usable technology for such applications, especially with PDAs as terminal devices. Moreover, we tested our architecture in a live scenario with respect to scalability and mobility.
