米国下院は1月12日，Emergency Amateur Radio Interference Protection Act of 2007 という法案の説明を行いました。以下はその全文です。法案説明を行ったMike Ross氏はアマチュア無線家だとのことです (WD5DVR)。

法案は，FCCに対し，90日以内にBPL許容値（電界強度）の妥当性や公共安全・無線通信に障害を与えないための新／改訂ルールのオプション等を議会に報告することを要請するものとなっています。（もちろん，成立すれば，です。）

Emergency Amateur Radio Interference Protection Act of 2007 (Introduced in House)

HR 462 IH

110th CONGRESS

1st Session

H. R. 462

To request a study by the Federal Communications Commission on the interference caused by broadband internet transmission over power lines.

IN THE HOUSE OF REPRESENTATIVES

January 12, 2007

Mr. ROSS introduced the following bill; which was referred to the Committee on Energy and Commerce

A BILL

To request a study by the Federal Communications Commission on the interference caused by broadband internet transmission over power lines.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

This Act may be cited as the `Emergency Amateur Radio Interference Protection Act of 2007'.

SEC. 2. COMPREHENSIVE BPL SERVICE STUDY LEADING TO IMPROVED RULES TO PREVENT INTERFERENCE.

(a) Authority- Within 90 days after the date of enactment of this Act, the Federal Communications Commission shall conduct, and submit to the Committee on Energy and Commerce of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate, a report on a study of the interference potential of systems for the transmission of broadband Internet services over power lines (in this Act referred to as `BPL service').

(b) Required Subjects of Study- The study required by this section shall examine the following:

(1) The variation of field strength of BPL service signals with distance from overhead power lines, and a technical justification for the use of any particular distance extrapolation factor.

(2) The depth of adaptive, or `notch', filtering for attenuating normally permitted BPL service radiated emission levels that would be necessary and sufficient to protect the reliability of mobile radio communications.

(3) A technical justification for the permitted, radiated emission levels of BPL signals relative to ambient levels of man-made noise from other sources.

(4) Options for new or improved rules related to the transmission of BPL service that, if implemented, may prevent harmful interference to public safety and other radio communications systems.
