Abstract
WiFi technology has become the preferable form for mobile users to connect to the Internet. The growing popularity of WiFi-enabled devices and the increasing number of WiFi networks guarantees that this trend will continue in the future. Since a single network provider is usually not able to ensure WiFi coverage for its own users across many geographic locations the WiFi roaming technology appears to be the promising solution. A special attention upon the practical deployment of WiFi roaming should be paid to possible threats coming from the misuse of technology. In this light we analyze various legal implications that might become relevant due to the deployment of WiFi roaming and discuss several risks and problems related to the security during the establishment of roaming connections between mobile devices and the Internet.
