SDBAPXCVR01AP/APX TRANSCEIVER MODULE

Federal Communications Commission Date 8-14-07 Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Gentlemen: Sensus Metering Systems respectfully requests confidentiality of certain materials provided with the submission of the APXCVR01 under FCC ID: SDBAPXCVR01 in accordance with FCC Regulations 0.459. The confidentiality request applies to the following: • 07-0351 - Schematics.pdf • 07-0351 – Parts List.pdf • 07-0351 - Theory of Operation.pdf • 07-0351 – Block Diagram.pdf • 07-0351 - Tune up Procedure.pdf • 07-0351 – Internal Photos.pdf • 07-0351 – User’s Guide.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 APXCVR01 has been developed at considerable effort and expense by Sensus Metering Systems. These items are considered as Trade Secrets and therefore public access to the proprietary material could possibly result in duplication of equipment that could severely damage the company’s business advantage. I appreciate your assistance in this matter.

The APXCVR01 also communicates using a Zigbee transceiver to devices within a few hundred feet. It therefore provides the user with a method of communicating between a remote system and various devices locally. Manufacturer Information: Sensus Metering Systems 8601 six forks Road Raleigh, NC 27615 Factory Contact: Bob Davis Sensus Metering Systems 114 Northpark Blvd Suite 10 Covington, LA 70433 985-773-1236 Detailed photographs of the EUT are filed separately with this filing. 1.3 Test Methodology and Configurations 1.3.1 Test Configurations and Justification The APXCVR01 is a module designed to be integrated into a host device therefore testing was performed on the module in a stand-alone configuration with the exception of AC power line conducted emissions. AC power line conducted emissions was performed with the module installed into a typical host device. For RF conducted measurements, the APXCVR01 was modified with an external RF connector to the PCB. The APXCVR01 utilizes non-detachable antennas for normal operation but for RF conducted testing the antennas were disconnected and a 50-Ohm test cable soldered (with the appropriate ground connection) to the PCB. Model: APXCVR01 FCC ID: SDBAPXCVR01 IC ID: 2220A-APXCVR01 ACS Report: 07-0351-LD Advanced Compliance Solutions Page 4 1.3.2 In-Band Testing Methodology For testing in accordance with 47 CFR 2.1046-2.1057, OET/Lab recommends that the following be used to select test frequencies for licensed devices: Frequency range over which device operates Number of frequencies Location in the range of operation 1 MHz or less 1 Middle 1 to 10 MHz 2 1 near top and 1 near bottom 10 to 100 MHz 3 1 near top, 1 near middle and 1 near bottom The APXCVR01 is designed to operate in multiple bands under the requirements of CFR 47 Parts 24, 90, and 101. The following is a list of the frequency bands of operation sorted based on the FCC rule parts in which the band is associated. CFR Title 47 Rule Part Frequency Band of Operation (MHz) 24D 901.0 - 902.0 24D 930.0 - 931.0 24D 940.0 - 941.0 90 896.0125 - 901.0 90 935.0 - 940.0 101 928.85 - 929.0 101 932.0 - 932.5 101 941.0 - 941.5 101 959.85 - 960.0 Based on the requirements set forth in accordance 47 CFR 2.1046-2.1057 as stated above, the methodology in selecting the places to test in the bands of operation is outlined in the following table. CFR Title 47 Rule Part Frequency Band of Operation (MHz) Location in the Range of Operation 90 896.0125 - 901.0 24D 901.0 - 902.0 1 near top and 1 near bottom 101 928.85 - 929.0 Middle 24D 930.0 - 931.0 Middle 101 932.0 - 932.5 Middle 90 935.0 - 940.0 24D 940.0 - 941.0 101 941.0 - 941.5 1 near top and 1 near bottom 101 959.85 - 960.0 Middle The data provided in this report is sorted based on the…
