Meeting called to order at 1:30 PM ET by Stephen Berger,

WG Membership & Voting Rights

The meeting open with Stephen Berger reporting that he will present to SC8 proposed procedures for identifying the WG members of WG3. These procedures will be modeled after those used by IEEE 802 and IEEE SCC41. They are intended to identify the active participants of WG3 and grant them voting rights in the WG.

After discussion it was decided that in some cases exception should be made for exceptional contributors to the WG who may fail to meet the technical requirements of the procedure. It was decided that a 2/3 vote of the committee would be used to decide who was an exception to the procedures. Steve Julstrom was identified during discussion as an example of someone who failed to meet the attendance requirements but was an outstanding WG member. By unanimous vote it was agreed that Steve should be granted membership and voting rights in the WG.

A discussion was held of who is currently qualified to be a voting member. It was decided that the initial roster should contain only the names of those attending today’s meeting. However, after the SC8 vote, if approved, the procedures should be sent to the reflector with an invitation that all who believed they meet the requirements for voting membership identify themselves to the chair. Project Status

A review was then held of the current project status. The project status, as it stands following the review is attached as an Annex these minutes.

Revision of PINS

It was decided to require a revision to the PINS, adding the following items:

1. To combine sub-clauses “4.4.1.2.1 Manual scanning method” and “4.4.1.2.2 Automated scanning method” into a single section requiring a positioning resolution and accuracy.

2. To add a ‘no RF test’ option for low power transmitters that are almost certain to achieve category 4 due to their low transmission power.

Work on Open Items

A review of the open items from the PINS was conducted, with the following results:

It was decided to approach some neutral labs with a request to support validation testing and development of the fast probe method and generalized AWF approach. Stephen Berger took the action to approach the laboratories that were mentioned. A 3 stage process was outlined, as follows: 1. Developing transfer functions for probes using AM modulated fields. 2. Measure and validate the transfer function developed in stage one using complex fields. 3. Run comparison scans using the current slow probes method to the new fast probe method.

Steve Julstrom was requested to prepare proposed wording in response to the PINS item “Determine and specify the power measurement that is most closely linked to user experience, peak, RMS or other parameter of power.”

Bob Zurich was requested to prepare proposed wording in response to the PINS item “To evaluate and possibly improve the specification of the band pass filter referenced in sub-clauses 6.1.1.1.2 and 3.”

Stephen Berger was asked to get the Delta data linked on the WG website.

A discussion was held of what information might inform the value of continuing to require the H-Field RF measurements. Stephen Berger agreed to collect and prepare past data presented to the committee which might be relevant to this question. A discussion was held about the need for target values for the new dipoles listed in Table 4.2. It was decided to eliminate all dipoles, except the 2 in the 700 MHz band, until a volunteer presents target values for other dipoles.

The meeting adjourned at 5:30 PM. Annex - ANSI C63.19 Project Status

# Status / PINS Text / Notes & Resolution

1 Status - Resolved To expand the frequency range of the standard to cover 698 MHz to 6 GHz.

The extension of the lower frequency range is to include the wireless mobile technologies in 698 MHz band as mandated by recent FCC Report and Order.

The extension of the upper frequency range up is to include newer technologies in the bands between 3 - 6 GHz, including the 4.9 GHz band as referenced in the latest FCC Report and Order 700 MHz task group has conveyed its recommendations to the WG. Its changes are reflected in the current draft.

1a Status - TBD a) Design/Testing and Simulation of Dipoles for the frequency extensions. Some test has been proposed. Needs discussion and resolution in the WG.

1b Status - Resolved b) Extend calibration range of test probes from 698 MHz to 6 GHz. Issue refered to WG for IEEE 1309 and NIST Fields Measurement Group.

2a Status - In progress To provide AWF factors for systems operating in the 698 MHz to 6 GHz frequency range. WG has agreed to ratain continuity with current AWF and testing methods using slow response probes as direct measurement methods are developed.

2 proposals received for an approach to a generalized AWF factor, one to use A- Weighting and a new weighting function has been proposed by Steve Julstrom. Issue needs further discussion and resolution by the WG.

Work is needed to map a direct measurement to the categories in the current standard and bridge direct measurements to slow probe measurments. Also AWF's will be needed for slow probes.

2b Status - In progress If possible to develop a generalized treatment based on A-Weighting or some other appropriate weighting to replace the AWF table. This issue has been linked with item #2. See comments under that item.

3 Status - In progress Evaluate the requirement in Clause 4, 7 and other appropriate sections for RF H- Field measurements. Discussion has tended toward retaining the H-Field measurment but the WG has not made a final resolution on the issue.

4 Status - In progress To evaluate the correlation of hearing aid immunity test results using the dipole and WB TEM methods and consider the advisability of different field strength requirements for each of the methods to bring the test methods into closer agreement. Proposal from HIA received. WG needs to have further discussion and make a final determination.

5 Status - TDB Review and update test equipment specifications generally, specifically Annex D.3, D.4 and D.7. Item has been discussed. A volunteer is needed to take the action to review and propose wording/editing to the current text.

6 Status - TBD To evaluate and possibly improve the specification of the band pass filter referenced in sub-clauses 6.1.1.1.2 and 3. Item has been discussed. A volunteer is needed to take the action to review and propose wording/editing to the current text.

7 Status - TBD Determine and specify the power measurement that is most closely linked to user experience, peak, RMS or other parameter of power. Item has been discussed. A volunteer is needed to take the action to review and propose wording/editing to the current text.

8 Status - Resolved Reconsider the need for 3 T-Coil positions relative to user needs. On March 4, 2008 Telecon WG agreed to use 2 positions, described as transverse and perpendicular.

9 Status - Resolved The RF probe separation distance is 1.5 cm and the calibration values in table 4.2 were made at 1.0 cm. These calculations need to be redone to the 1.5 cm distance. Values for 1.5 cm have been presented and placed in the current draft.

10 Status - In progress To review and adopt any editorial improvements proposed, including review and update of references and bibliography. Changes are either brought to WG for consideration or reflected in draft when proposed. Action Items From Meeting # Item Responsible Party 1 Action item: Distribute draft to ad hoc.
