1 doc.: IEEE 802.11-10/0368r0 Submission March 2010 Slide 1 Notice: This document has been prepared to assist IEEE 802.11. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at.http:// ieee802.org/guides/bylaws/sb-bylaws.pdfstuart.kerry@philips.compatcom@ieee.org Date: 2010-03-16 Authors: NameCompanyAddressPhoneEmail Johannes Lessmann NEC Europe Ltd.Kurfuersten-Anlage 36, 69115 Heidelberg, Germany +49-6221-4342-165lessmann@neclab. eu Christian Niephaus Fraunhofer Institute Schloss Birlinghoven, 53754 St. Augustin, Germany +49-2241-142785Christian.niephaus @fokus.fraunhofe r.de Antonio de la Oliva U.

8 doc.: IEEE 802.11-10/0368r0 Submission Media Independent Link Interface

9 doc.: IEEE 802.11-10/0368r0 Submission Why IEEE 802.21? It offers media independence It specifies many of the needed primitives already It offers the required communication mechanisms However, there are still points missing to enable wireless network management and some new primitives would be needed

15 doc.: IEEE 802.11-10/0368r0 Submission DSL Backhaul

16 doc.: IEEE 802.11-10/0368r0 Submission Additional Use Case Scenarios “Stadium”, proposed by BT  low-cost, short-term provisioning of additional wireless access capacity  triple-play QoS requirements “Emergency Response Support”, proposed by DT  severe capacity constraints  intermittent connectivity to core network  sub-optimal node placement  focus on group-communication Internet

17 doc.: IEEE 802.11-10/0368r0 Submission LinkNet Macha Project in Zambia Villages and the houses within those villages are scattered across a large land No wired communication No reliable power supply Limited hardware resources Limited budget Target: Deploy a country-wide heterogeneous wireless backhaul which is reliable enough to provide affordable connection throughout the country First devices have been deployed by Fraunhofer Institute in September 2009

18 doc.: IEEE 802.11-10/0368r0 Submission Conclusion Heterogeneous wireless networks are a promising solution in a number of use cases Required functionality is covered to a large extent by IEEE 802.21 due to its media independence Consortium of companies/research institutes have investigated and are currently implementing a heterogeneous backhaul using IEEE 802.21 extension, i.e. media independent link interface 802.11 is one key technology in a heterogeneous networks context
