“The ITU-R TG 1/8 meeting in Boston was a huge success in regard to the global adoption of UWB. The Delegates saw firsthand and many for the first time, the successes we've achieved in the development of UWB. This came at a critical juncture as many administrations have or will shortly begin their rule making processes. These delegates were genuinely impressed by what they experienced and will no doubt evangelize our message to the masses. It should also be noted that the IEEE's involvement in this process as a Sector member of the ITU-R speaks volumes to their commitment to reach beyond the U.S. borders and recognizes that any standard accepted here must also have a universal appeal in order to be adopted worldwide.”

[PROPAGATION PREDICTION METHODS FOR UWB COMPATIBILITY STUDIES

The following text is proposed for insertion as shown below, based on the contents of documents 1-8/111, 1-8/126, and USTG 18-53.

Introduction

By the last meeting of ITU-R TG 1/8, October 2003, it was decided to update and further develop the chapters on UWB propagation of the PDNR ITU-R SM.[UWB.COMP] and of the Report on compatibility studies. Liaison statements were sent to WP 3K and WP 3M in Documents 3K/12, 3M/21 requesting information on appropriate propagation models for ultra-wideband emissions that are needed for compatibility assessment with radiocommunication services. By considering the Liaison statement sent back by WP 3K to TG 1/8 in Document 1-8/60 including the attachment 3K/30 and remarks sent by some authors of the different UWB propagation studies described in A1.2.1.4 of Annex 2 to Document 1-8/59 (UWB path loss models) the chapter A1.2.1.4 of the PDNR ITU-R SM.[UWB.COMP] and the chapter 4.1 of the Report on compatibility studies can therefore be updated. In the following, the new versions of these two chapters are presented.

Sample Excerpts from a “TEMP”: FSS

... ... Document 1-8/107 (UK/Inmarsat)

“Revision of Studies of the Compatibility Analysis between GSO MSS Systems and Ultra-Wideband (UWB) Systems” ... ...

The following provisional conclusions can be drawn ... in the downlink direction:

Separation distances

– ... separation distances of 10 km are required from peak power UWB emissions ...

Maximum permissible EIRP density in 1 MHz bandwidth at 10 m distance

– The maximum permissible EIRP density varies from –62.25 dBm/MHz to –47.54 dBm/MHz from non-dithered average emissions with different PRFs.

– The maximum permissible EIRP density varies from –116.6 dBm/MHz to –47.54 dBm/MHz from non-dithered peak emissions with different PRFs.

– The maximum permissible EIRP density varies from –116.6 dBm/MHz to –63.56 dBm/MHz from dithered emissions with different PRFs .

ITU-R Recommendations

• Chairman’s Report basis for “Report” and “PDNR”• “Recommendations” (PDNR) are the key document• PDNR to be the basis for implementation of UWB

regulations by individual Nations• US Position: Don’t want “Recommendations” to

result in any restrictions of existing US rules on UWB

IEEE Role in ITU

• IEEE is “Regional International Member” in ITU-R (Radiocommunications Sector)– IEEE can contribute documents directly to ITU-R (but with lots of bylaw

and bureaucratic obstacles)– Another route for IEEE wireless standards to enter the international

community

• IEEE also works closely with the ITU Telecommunication Standardization Sector (ITU-T)– IEEE recognized in 2000 by ITU-T as an international organization

whose work is referenced in ITU-T Recommendations following procedures developed by ITU-T

• IEEE802 individuals can work through their State or Sector

IEEE UWB Opportunity in ITU-R

• ITU and USTG 1/8 are seeking technical contributions which show the compatibility of UWB with existing services

• IEEE is “Regional International Member” of ITU-R, can directly contribute to TG 1/8 meetings (bylaws govern how IEEE can act)

• IEEE, as “RIM”, can use own criteria for compatibility• IEEE802 individuals should seek out State and

Sector Members as routes for contributions
