3. Submission doc.: IEEE 11-13/1325r3 Introduction to TGai: Fast Initial Link Setup (FILS) FILS includes all operations required to expedite IP packets exchange during initial link setup. The main operations include: Network and BSS discovery Authentication and association Higher layer setup such as IP address configuration FILS focuses on an environment where mobile users are constantly entering and leaving the coverage area of an extended service set (ESS). Every time the mobile device enters an ESS, the mobile device has to do an initial link set-up. This requires efficient mechanisms that: (a) scale with a high number of users simultaneously entering an ESS (b) minimize the time spent within the initial link set-up phase (c) securely provide initial authentication.

4. Submission doc.: IEEE 11-13/1325r3 Today’s Market Trends Growth of mobile device market – Majority of the Wi-Fi devices are mobile devices True mobile usage: Users frequently pass through (isolated) hot spots while on the move The dwell time of an user within a cell is short Isolated hot spots cause frequent initial association /authentication (link setup) New application’s request (Twitter, Facebook…) Push Notification Service Short and quick updates High bandwidth Very SMALL CELL of each AP So even with short dwell time under a given AP, always-on connectivity is a must Slide 4 Hiroshi Mano (ATRD) Nov 2013
