Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < ieee802.org/guides/bylaws/sb-bylaws.pdf>, 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 Working Group.

Abstract
This document is the third IEEE – TIA TR8 liaison report.
The first report ( , September 2005) provided an overview of TIA, with emphasis on Broadband activities.
The second report ( , November 05) provided an overview of the public Safety Use Cases considered for communication in an incident scene.
This report summarizes recent activities within the Broadband Task Group (BBTG) that is evaluating suitable protocols for an incident scene in the Public Safety 4.9GHz band.

Broadband Task Group
A Broadband Task Group (BBTG) was created in October 2005 to evaluate the needs of Public Safety users for wireless broadband applications considered by TR8.
The BBTG currently reviews proposals for using and in the 4.9GHz band as a PHY/MAC protocol for public safety in the incident scene.
The evaluation process consists of two parallel activities:
Developing airlink requirements for public safety needs
Simulate typical use cases to evaluate the performance of the two protocols
Various authorities (such as the Department of Homeland Security) would prefer that only one protocol is selected to be deployed in the 4.9GHz band. This will help ensure interoperability in the band.

4. Airlink Requirements - Current Status
September 2006
Airlink Requirements - Current Status
The implications of public safety users’ requirements on the airlink in an incident scene are now being finalized. Among the important issues are:
Operate in an infrastructureless mode
Provide QoS mechanisms
Provide sufficient security
Scalable and extensible with minimal management provisions
Support layer 2 handover
Others

5. Use Case Simulation - Current Status

Use Case Simulation - Current Status
Simple use cases were simulated for incident scenes involving a single public safety jurisdiction: Police, EMS and Firefighters.
Communications in the incident scene involved fairly light traffic loads.
The simulation results demonstrated excellent communication performance commensurate with mission critical expectations for video, voice and various data applications.
A comprehensive use case is now being analyzed with five different jurisdictions in a large incident scene (one mile by one mile). Six simultaneous video feeds in addition to heavy voice and data traffic are simulated.
It is anticipated that results will be available later this year or in early 2007.

Other Activities
A replay to a liaison letter from TR-41.4 regarding emergency calls services for VoWLAN was sent in July ( ). Emergency calls service for users without proper authentication credentials are being discussed in TGu.
