20420 Century Boulevard Germantown, MD 20874 (301) 944-2700 (phone) (301) 944-2701 (fax) June 1, 2007 FEDERAL COMMUNICATIONS COMMISSION Office of Engineering & Technology 7435 Oakland Mills Road Columbia, MD 21046 Subject: Request for confidentiality for FCC ID: TY7210-0152 To Whom It May Concern: Pursuant to 47 CFR Sections 0.457 and 0.459, CURRENT Technologies, LLC (“CURRENT”) hereby requests non-disclosure and confidential treatment of the following materials submitted in support of FCC certification application for FCC ID # TY7210-0152. a. Block Diagram b. Internal Photos c. Operational Description d. Installation Instructions e. Notching Instructions The above materials contain trade secrets and proprietary, technical information that CURRENT would customarily guard from competitors. See 47 C.F.R. § 0.457(d)(2). Disclosure or publication of any portion of this confidential material to other parties could cause substantial competitive harm and provide unjustified benefits for competitors. The information in these exhibits is not available to the general public. This information, including that in the internal photos, is not disclosed to third parties except under protection of a confidentiality agreement that prohibits further disclosure. Therefore recipients of this information are constrained by contract from showing the equipment or discussing its operation to anyone not approved by CURRENT. Although the underlying equipment is installed outdoors, all installations (as well as equipment removal and in-situ maintenance) are performed only by certified utility company linemen or contractors, and once installed the equipment resides in the “power space” of utility poles where electric distribution lines are hung. Access to this space is very dangerous and under the National Electric Safety Code is strictly limited to qualified utility workers certified to work within such “power space.” Finally, the underlying equipment is serviceable only by CURRENT or a CURRENT- authorized third party. As a result, the design details of the equipment, including internal photos, are hidden from competitors and protected against public disclosure. The equipment design, as shown in the internal photos, was developed by CURRENT at great expense. Disclosure of this information via the FCC website would convey an unfair and unearned competitive advantage to other companies in this market. CURRENT is entitled to have the information protected pursuant to Worthington Compressors v. Costle, 662 F.2d 45, 51 (D.C. Cir. 1981). Sincerely, Jay Birnbaum Vice President & General Counsel (301) 944-2702 (phone) (301) 944-2701 (fax) [email protected]

20420 Century Blvd. Germantown, MD, 20874 Phone 301 944-2700 Fax 301 944-2701 June 1, 2007 CURRENT Technologies, LLC is applying for Part 15 Limited Modular Approval (LMA) from the Federal Communications Commission (FCC) for its CT S4e Meter board. The CT S4e Meter board is part of an Access BPL system. It combines traditional power meter functions with BPL signaling capability over the low voltage wires. Pursuant to FCC document DA 00-1407, CURRENT Technologies is submitting the supporting documentation listed below for Part 15 Unlicensed Modular Transmitter Approval. The numbered requirements of DA 00-1407 are satisfied as shown below: 1) The S4e Meter module requires no additional RF shielding. It simply consists of a circuit board that is added to the L+G S4e electricity meter. 2) The S4e Meter module includes buffered data outputs to ensure no deviations from Part 15 limits can be caused from elements outside the module. 3) The S4e Meter module contains its own power supply, and also supplies regulated power to the electricity meter itself. 4) As the requested approval is for an Access BPL device, the S4e Meter module uses no antenna and the antenna requirements are not applicable. 5) The S4e Meter module is contained wholly within an L+G S4e model electricity meter. Given the in-situ nature of required emissions testing for Access BPL devices, the S4e Meter module was contained within an L+G S4e electricity meter for all testing. LMA approval is requested for the S4e Meter module contained only within this meter. For all testing, the meter was installed as per standard instructions with no ferrites or other special devices intended to limit emissions. 6) The outside of the meter itself is labeled as per the labeling instructions, document number 300-0000-0073, included as part of this certification application. 7) The S4e Meter module complies with all applicable rules when properly installed per meter manufacturer instructions. 8) The S4e Meter module only emits energy as an unintentional emitter and meets the emissions limits for unintentional emitters. These limits are well below all applicable RF exposure guidelines. Enclosing the S4e Meter module within an electricity meter, allows normal electric utility metering operation practices to be used to ensure proper installation of the meter at all times. Electricity meters are always professionally installed and include tamper indicators to ensure that consumers may not remove or otherwise modify the installation. The detailed installation practice is shown in the meter installation procedure included as part of this certification application. Respectively Submitted, Steve Seymour CURRENT Technologies

CURRENT Technologies, LLC CT S4e Meter Interference Mitigation and Avoidance June 8, 2007 1 CURRENT Technologies, LLC Interference Mitigation and Avoidance CT S4e Meter 1. Notching Overview The charts below demonstrate compliance with paragraph 15.611 (c)(1)(i) of the FCC BPL Report and Order dated October 28, 2004. Interference mitigation is accomplished by removing specified OFDM carriers from the selected meter via a software download commanded remotely over the low voltage power line by CURRENT’s network management system. A simple user interface allows the system operator to specify which carriers will be removed by number according to the table shown in Section 1.4. 1.1 Baseline BPL Meter Output The following chart shows the transmit power spectrum of the AMR meter as-shipped from the factory. CT s4e Meter - Default Output Spectrum -110 -105 -100 -95 -90 -85 -80 -75 -70 -65 -60 -55 -50 2.55.07.510.012.515.017.520.022.5 Frequency (MHz) Power (dB) CURRENT Technologies, LLC CT S4e Meter Interference Mitigation and Avoidance June 8, 2007 2 1.2 Notched BPL Meter Output The following chart shows the transmit power spectrum of the same device measured above following a remote software change which removed carriers 6 through 12. The notch shows the required 20 dB suppression. CT s4e Meter - Notched Tones 6-12 Output Spectrum -110 -105 -100 -95 -90 -85 -80 -75 -70 -65 -60 -55 -50 2.55.07.510.012.515.017.520.022.5 Frequency (MHz) Power (dB) CURRENT Technologies, LLC CT S4e Meter Interference Mitigation and Avoidance June 8, 2007 3 1.3 Notched BPL Meter Output following a Power Cycle The following chart shows the transmit power spectrum of the same device measured in sections C.1.1 and C.1.2 of this document following a power cycle in order to demonstrate persistence through a power cycle as required by FCC Part 15.611 section C. CT s4e Meter - Notched Tones 6-12 Output Spectrum - After Power Cycle -110 -105 -100 -95 -90 -85 -80 -75 -70 -65 -60 -55 -50 2.55.07.510.012.515.017.520.022.5 Frequency (MHz) Power (dB)
