The Internet Society is organizing a briefing panel on Tuesday, 6 November, from 11:45am to 12:45pm, at IETF 85 in Atlanta. This is to provide information on the topic and on registration for the panel. Internet Untethered? The mobile data network world has changed significantly in the course of the last 4 years as game-changing smartphones have come online, tablets are hitting the scene. Users have taken up these devices with enthusiasm, and put them to uses not ever envisioned by their creators or the operators of the networks that support them. And with increasing speed and power (of devices and mobile data networks), users are expecting broadband Internet experience while on the move. This panel will explore the evolution of the mobile data network reality through key questions: How have these new devices impacted the evolution of mobile data services and offerings of mobile Internet, especially in terms of bandwidth management? What are the key factors in evolving from a mobile data service to mobile Internet? Many ubiquitous web-based services (Wikipedia, Facebook, Twitter) are increasingly accessed through dedicated applications on the smartphone. What are the drivers for this and where is it taking the Internet user's reality? Information on the briefing panelists will be posted at: http://www.internetsociety.org/internet-society-panel-ietf-85 Due to high demand for limited seating at Internet Society panel events, we are providing you with advance information about registration.
