The mention of such entities should not be construed as any endorsement, approval, recommendation, prediction of success, or that they are in any way superior to or more noteworthy than similar entities that were not mentioned. iii PREFACE ISART 2012 was the thirteenth in a (more or less) annual series of symposia hosted by ITS. Since the first ISART in 1998, the conference has evolved from having a purely technical focus based on presentations of papers to providing a neutral forum where business experts, technologists, and government regulators can share their points of view, debate issues, and engage in a holistic and expansive exploration of the future use of existing and emerging radio technologies. Under the new format a greater proportion of the material was derived from slide presentations. Accordingly, the mechanics of maintaining a record of the events has evolved over time. Speaker slides have always been published. In 2003, a call for papers was issued and Proceedings were published. In 2010, there was no formal call for papers, although some were submitted. For the first time in 2010, ISART was made publicly available as a real-time live videocast. Consequently, rather than publishing formal proceedings, the organizers experimented with publishing, in electronic form only, the videocast record of the conference, the slides, and any papers submitted by presenters. Feedback on this method of preserving a record of the event was decidedly mixed, but a clear preference for a written record emerged. The 2011 proceedings are an edited version of an informal transcript of the conference, a best effort to summarize information presented and articulated at the conference which speakers were invited to review. Between 2010 and 2012, ITS was given more stringent directives about closed captioning of online published video. To accommodate those directives, all ITS published video was taken down for a period of time, and in 2012 a court reporter was engaged to keep a transcript of the conference. This allowed both the development of closed captioning for the video recording so it could be posted online and publication of the transcripts as proceedings. This volume of proceedings is taken directly from the court reporter’s transcription of the conference. A best effort has been made to correct spellings of names and terms of art, but it is in no way an “edited” transcript. v CONTENTS Preface..............................................................................................................................................v 1.
