2. Telemetry Augmentation in the WRC Process
Based on WRC 2005/6 preliminary agenda item 2.12 to consider spectrum requirements for wideband aeronautical telemetry in the band between 3-30 GHz
This agenda item is being addressed by ITU-R Working Party 8B
POC is Mr. George Wardle, Australian DoD
U.S. had an informal meeting with Mr. Wardle in August
M. Ryan, representing ICTS
D. Portigal, MITRE
C. Glass, U.S. WP 8B

3. Telemetry Augmentation in the WRC Process (Continued)
Mr. Wardle made a number of points :
He emphasized the need to gather support for this proposed agenda item to ensure that it is actually placed on the agenda
He noted that any attempt to obtain any exclusive allocation for wideband aeronautical telemetry would raise opposition from some administrations
He advocated the proper procedure would be to identify existing allocations that could also support wideband aeronautical telemetry
His suggested criteria are allocation to Mobile Service with no prohibition against Aeronautical Mobile use

4. Telemetry Augmentation in the WRC Process (Continued)
Mr. Wardle has drafted an Administrative Circular Letter and questionnaire to support this process
These items are being considered by ITU-R WP 8B this month - finalized versions will be circulated to national administrations
In order to ensure that this issue is not lost, we need to make sure that all interested parties obtain and respond to this package
We also need to ensure that this response is received by and actively processed in WP 8B
Prospective users need to participate through their national administrations
If possible, participate in WP 8B

5. Telemetry Augmentation in the WRC Process (Concluded)
Circular Letter states that this agenda item does not negate the need for spectrum below 3 GHz
Intended to support new/different telemetry capabilities with large data transfer needs
For those who plan to operate above 3 GHz, questionnaire seeks information on:
Kinds of programs that need this and their spectrum requirements
What appropriate national allocations exist
Where wideband telemetry would be employed
Technical & operational characteristics of proposed systems
Sharing arrangements with incumbent users

7. Questionnaire (Continued)

8. Questionnaire (Concluded)

9. MITRE Preliminary Assessment on Telemetry Spectrum Harmonization
Assessment based on information that is available over the Internet
Searched over 4-10 GHz and around 15 GHz
Organized around U.S allocations and the allocations found in ERO Recommendation 25
Recommended common European allocation starting 2008
No obligation for member administrations to adopt recommendation
Also include current allocations for a number of European and other countries
Primary Mobile, Aeronautical Mobile allowed
