Bowman Drive Buford, GA 30518 Re: FCC ID: SDBVGB To Whom It May Concern: The following application is submitted on behalf of our client Sensus Metering Systems, Inc. for evaluation of their models 4500-MAS, 4500-PCS for Certification under CFR 47 Part 24 Subpart D, and Part 101. The 4500-MAS and 4500-PCS are Vehicle Gateway Base stations (VGB) used in the utility industry for mobile meter reading applications. The VGB Models 4500-MAS and 4500-PCS are electrically identical in all aspects with the exception of a diplexer used in the receiver operation. The diplexer allows the 4500- MAS unit to receive in the range 932 - 932.5 MHz and the 4500-PCS to receive in the range 901 – 902 MHz. The VGB models 4500-MAS and 4500-PCS were tested in full to the requirements of the aforementioned rules and were found to be in compliance.

The device is capable of sending standard data packets or an interrogation tone capable of interrogating utility endpoints operating in drive by mode. The VGB is intended to be used with a PC application since the device alone has no intelligent application processor. The VGB Models 4500-MAS and 4500-PCS are electrically identical in all aspects with the exception of a diplexer used in the receiver operation. The diplexer allows the 4500-MAS unit to receive in the range 932 - 932.5 MHz and the 4500-PCS to receive in the range 901 – 902 MHz. Manufacturer Information: Sensus Metering Systems, Inc. 400 Perimeter Park Drive, Suite K Morrisville, NC 27560 Test Sample Serial Numbers: SN: 0942FT0005 (RF conducted), SN: 0942FT00005 and SN: 0942FT00006 (radiated) Test Sample Condition: The test samples were provided in good working order with no visible defects. Detailed photographs of the EUT are filed separately with this filing. 1.3 Test Methodology 1.3.1 Test Configurations and Justification While both 4500-MAS and 4500-PCS models are electrically identical from an RF perspective, differences in the diplexer for receive operation required receiver / unintentional radiated emissions testing on both variants. Where applicable, the additional testing was performed on both models and the worst case presented in this report. Per TIA 603-C, the RF output port was loaded with a 50 Ohm non-radiating load for radiated emissions from the transmitter. 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 1Middle 1 to 10 MHz 21 near top and 1 near bottom 10 to 100 MHz 3 1 near top, 1 near middle and 1 near bottom Model: 4500-MAS, 4500-PCS FCC ID: SDBVGB IC: 2220A-VGBMAS, 2220A-VGBPCS ACS Report: 09-0350.W06.11.A Advanced Compliance Solutions Page 4 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 940.0 - 941.0 101 941.0 - 941.5 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 available 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 24D 940.0 - 941.0 Middle 101 941.0 - 941.5 Middle The data provided in this report is sorted based on the rule part. 1.4 Emission Designators The transmitter produces three distinct modulation formats. The emissions designators for the modulation formats used by the transmitter are as follows: EMISSIONS DESIGNATORS: MPass Mode (5K): 5K90F1D (2-GFSK) MPass Mode (10K): 11K8F1D (2-GFSK) MPass Mode (12.5K): 14K8F1D (2-GFSK) Model: 4500-MAS, 4500-PCS FCC ID: SDBVGB IC: 2220A-VGBMAS, 2220A-VGBPCS ACS Report: 09-0350.W06.11.A Advanced Compliance Solutions Page…
