Re: WT Docket No. 01-309

Dear Ms. Dortch:

This is to update the Federal Communications Commission (Commission) on the Alliance for Industry Solutions (ATIS) Incubator Solution Program #4 (AISP.4-HAC or Incubator).

On Monday, May 17, 2004, AISP.4-HAC submitted its Initial Report regarding the industry’s hearing aid compliance efforts. This report was filed pursuant to the reporting requirements adopted by the Commission in its August 14, 2003, Report and Order in WT Docket No. 01-309, and submitted on behalf of the members of the AISP.4-HAC.

At the time of the report, the Incubator included participation by twenty-nine (29) wireless equipment manufactures and service providers. Since the filing of the Initial Report, AISP.4-HAC has added a new member, Communications, Inc. Therefore, attached please find an updated industry status report table and as well as an updated list of AISP.4-HAC members.

Should you have any questions, please contact me at 202-434-8847.

Sincerely,

Respectfully Submitted by:
