Abstract

   This document provides an overview of a workshop held by the Internet
   Architecture Board (IAB) on wireless internetworking.  The workshop
   was hosted by Nokia in Mountain View, CA, USA on February 29 thru
   March 2, 2000.  The goal of the workshop was to assess current and
   future uses of Internet technology in wireless environments, to make
   recommendations on research and standardization tasks to improve
   acceptance of Internet network and transport protocols in wireless
   environments, and to evaluate methods to improve communication and
   collaboration among Internet standards working groups and those of
   the telephony and wireless sectors.  This report summarizes the
   conclusions and recommendations of the IAB on behalf of the IETF
   community.

   Comments should be submitted to the IAB-Wireless-Workshop@ietf.org
   mailing list.
