Federal Communications Commission Date: September 05, 2007 Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Gentlemen: Itron, Inc. respectfully requests confidentiality of certain materials provided with the submission of the CENTRON Open Way under FCC ID: SK9AMI-2A in accordance with FCC Regulations 0.459. The confidentiality request applies to the parts list, schematics, block diagrams, theory of operation, internal photographs, and manual contained in following Exhibits: 07-0273 – Schematics.pdf 07-0273 – Parts List.pdf 07-0273 – System Block Diagram.pdf 07-0273 – Theory of Operation.pdf 07-0273 – Internal Photos.pdf 07-0273 – Manual.pdf Confidentiality of the Internal Photos is being requested because this is a non-consumer device which is not accessible by the general public and is only serviceable by the licensee or designated technicians. The User’s Guide is very technical and is not provided to the consumer because the consumer cannot service or install the device. Therefore confidentiality of the User’s Guide is also requested. The Open Way has been developed at considerable effort and expense by Itron, Inc. These items are considered as Trade Secrets and therefore public access to the proprietary material could possible result in duplication of equipment that could severely damage the company's business advantage. I appreciate your assistance in this matter. Sincerely, Name: Lee Littlejohn Signature: Title: Compliance Engineer Date: September 05, 2007

Summation of Power Densities – Simultaneous Transmissions This device contains multiple transmitters which can operate simultaneously and therefore the maximum RF exposure is determined by the summation of power densities. The 900 MHz LAN and high power Zigbee radio can not operate simultaneously there it is not appropriate to include both of those power density values in the same summation of power densities. For the sake of providing the worst case data, the highest power density from those two transmitters will be applied for the calculations. The maximum power density as calculated by a summation of power densities for each simultaneous transmission combination as follows: GPRS Modem Operating in the 800MHz Cellular Band: 900MHz LAN: 0.062 (mW/cm^2) 2.4GHz Zigbee: 0.000 (mW/cm^2) GSM 850 (GPRS): 0.346 (mW/cm^2) TOTAL: 0.408 (mW/cm^2) GPRS Modem Operating in the 1900MHz PCS Band: 900MHz LAN: 0.062 (mW/cm^2) 2.4GHz Zigbee: 0.000 (mW/cm^2) GSM 1900 (GPRS): 0.397 (mW/cm^2) TOTAL: 0.459 (mW/cm^2) Installation Guidelines: The installation manual shall contain text similar to the following advising how to install the equipment to maintain compliance with the FCC RF exposure requirements: “RF Exposure (Intentional Radiators Only) In accordance with FCC requirements of human exposure to radiofrequency fields, the radiating element shall be installed such that a minimum separation distance of 20cm is maintained from the general population.” Conclusion: This device complies with the MPE requirements by providing adequate separation between the device, any radiating structure and the general population.

The CENTRON OpenWay meter incorporates a two-piece design combining a base metrology with a variety of OpenWay registers or options. The metrology portion of the meter contains all measurement circuitry and calibration information, while the personality modules contain the register functionality and communication mediums. Each version of the meter is distinguished by the various personality modules or option boards that mount to the standard meter metrology base. For the purpose of this report, only the CENTRON OpenWay CVSOR-A meter type was evaluated. The CVSOR-A register board contains (1) 900 MHz LAN frequency hopping spread spectrum radio and (1) 2.4 GHz direct sequence spread spectrum Zigbee radio. The Cell Relay Core board, located in the meter base, contains (1) low power 2.4 GHz direct sequence spread spectrum Zigbee radio. The CVSOR-A also incorporates a pre-approved 850/1900 GPRS modem module FCC ID: MIVGSM0108. Manufacturer Information: Itron Electricity Metering, Inc. 313 North Highway 11 West Union, SC 29696 Detailed photographs of the EUT are filed separately with this filing. 1.2.2 Intended Use The CENTRON OpenWay meter is used for measuring electrical energy consumption. 1.3 Test Methodology and Considerations The CVSOR-A was evaluated for all modes of operation and worst case data presented in this report. The 900 MHz LAN and Zigbee radios located on the register board can not operate simultaneously. However, the Zigbee radio located on the Cell Relay Core board and the GPRS modem module can operate simultaneously with each other and with either the 900 MHz LAN or register board Zigbee radio. Radiated inter-modulation products were evaluated where applicable. This device is considered a composite device by definition. The 900 MHz LAN and the 2.4 GHz Zigbee radios on the register board operate under CFR 47 Part 15.247 and IC RSS-210. The 2.4 GHz Zigbee radio located on the Cell Relay Core board operates under CFR 47 Part 15.249 and IC RSS-210. This report addresses Part 15.249 and RSS 210 for the 2.4 GHz Zigbee radio located on the Cell Relay Core board only. Separate reports will be issued for Part 15.247 and RSS 210 in reference to the 900 MHz LAN and 2.4GHz Zigbee radios located on the register board.
