Page 1 of 5 Aclara RF, Inc. 30400 Solon Rd. Solon, OH 44139 440-528-7451 FCC ID: LLB09014 PREVIOUS TYPE ACCEPTANCE The radio transmitter submitted (LLB09014) herein is used as a telemetry device for the reading of utility meters. An operationally identical device (LLB6327) was previously submitted for Type Acceptance and received a Grant of Type Acceptance on March 4, 1998. This earlier version has been in field service since the grant was issued. Later, (12.12. 2003) identical Hexagram transmitters (LLB6327P & LLB10051M) received a Grant of Type Acceptance. The product described in this application (LLB09014) is modified version of LLB10051M. The block diagram and basic circuit configuration of the new product is identical to that of the original LLB6327P (and LLB10051M). As detailed in Exhibit D “Description of Operation, the semiconductor lineup has been changed from LLB6327P device in order to accommodate new application requirements, such:  Additional RF Power amplifier  Efficient RF power Amplifier  External Antenna Enclosure,  PC Board layout to accommodate new application Also, attached is a “Statement Concerning Compliance with Section 90.203 (j) (3)”. The identical statement was submitted with the application for Type Acceptance of the earlier LLB6082 & LLB 10051M devices. Page 2 of 5 STATENET CONCERNING COMPLIANCE WITH SECTION 90.203(J)(3) Introduction Section 90.203 (j)(3) of the Commission’s Rules on transmitters provides, in pertinent part: If the equipment [in the 150-174 and 421-512 MHz bands] is capable of transmitting data and has an overall bandwidth of 6,25 kHz or more, the equipment must be capable of supporting a minimum data rate of 4800 bits per second per 6.25 kHz of bandwidth. 1 Three parties interested in remove utility metering sought reconsideration of this provision to allow alternative showings of spectrum efficiency for low power frequency reuse systems. 2 The commission replied: [W]e will provide manufacturers with additional flexibility to design spectrally efficient transmitters. The commission’s Equipment Authorization Division may, on a case by case basis, grant type acceptance to equipment with slower bit rates than specified in Section 90.203(j)(3) and 90-203(j)(5) of our rules, provided that an acceptable technical analysis is submitted with the application, which demonstrate that the slower data rate will provide spectral efficiency than the standard data rate. 3 The present application is for automatic remote meter equipment, and falls squarely within the scope of this exception. When considered as part of a system, the device in question provides spectrum efficiency and channel utilization far excess of 4800 bits/sec per 6.25 kHz. Technical Analysis The device submitted for type acceptance is a Meter Transmitter Unit (MTU). When the system is implemented, an MTU is attached to each utility meter. The MTU periodically transmits meter readings omni-directionally in transmissions lasting under one-tenth second each. Transmissions from different MTUa are independent and uncorrelated. Data-collector Units (DCU) are mounted on a nominal 1 mile grid. A DCU receives and stores the transmissions from all the MTUs in its range. Once, daily, each DCU transfers the accumulated data to a central computer at the utility office via a cell phone mounted on the DCU. MTU bandwidth is 12.5 kHz, so a strict application of section 90.203(j)(3) would require the equipment to support a data rate of 9600 bits/sec. In fact, to minimize component cost and bit error rate, an individual MTU transmits at rate of 1200 bits/sec. The system achieves spectrum 1 47 C.F.R. para 90.203(j)(3). This provision governs Part 90 type acceptance applications filed from August 1, 1996, through December 31, 2004. 2 Replacement of Prt 90 by Part 88 to revise the private Land Mobil Radio Services, 11 FCC Rcd 17676, 17686 (1996). 3 Id., 11 FCC Rcd at 17687 (emphasis added). Page 3 of 5 efficiency not through a high bit rate in each individual MTU, but through a high level of frequency re-use achieved by deploying a large number of low-power short range transmitters. As detailed in the Appendix, a typical large installation of MTUs on a single 12.5 kHz channel can support data rates exceeding 100,000 bits/sec. This performance represents spectrum efficiency far in excess of that required under Section 90.203(j)(3). Where a typical commercial user of private land mobile radio spectrum, such as a delivery service, requires a pair of channels to provide two-way communication with dozens of trucks at most, the MTU is a part of a system that uses a single channel to service millions of users and to carry data representing billions of dollars in annual revenue. This is an extremely efficient use of the spectrum, and is consistent with the Commission’s purposes underlying Section 90.203(j)(3). An operationally identical MTU (LLB6082 & LLB10051M) received a grant of Type Acceptance on March 4, 1998 & October 2005. Automatic Meter Reading Systems incorporating this technology have been in service since March 4, 1998 and have incorporated tens of thousands of transmitters. The MTU described in this application for Certification represents an improved product. An earlier product (LLB5155) operating under the Commission rules then in effect has been in service at hundreds of locations since May of 1996. Public Interest Considerations Public interest considerations support the development of Automatic Meter reading equipment, such as the device in question. Automatic Meter Reading equipment directly helps to keep consumer rates down in the time of rapidly increasing labor cost. The alternative, traditional door-to-door meter reading, is not only much more expensive, but dangerous for the meter readers, and necessarily exposes consumers to potential security risk in their homes. Equally important in a pro-competitive regulatory environment, Automatic Meter Reading equipment makes possible time –of-use b…

LLB09014 May 21, 2010 RF Exposure calculations Based on FCC 1.1307 & 2.1091, FCC OET Bulletin 65. (1) Absolute Maximum specifications of LLB09013 transmitter  Operational frequency band 450 MHz to 470 MHz.  The LLB09014 transmitter is measured for Max RF Power = 1.698 W.  Absolute Maximum transmission time (duration) for any Aclara RF transmitters does not exceed 150 mS (0.15second).  Transmission period – Absolute maximum is 1 transmission per 4 hours.  All Aclara RF Transmitters utilize FSK modulation. (2) Average RF Power Calculation: FCC regulations on permissible RF exposure are not based on peak envelope power (PEP), but on average power (P_ave) over a 30-minute time period for uncontrolled environments. As mentioned in (2), during any 30 minute Aclara MTU can transmit only once. Duration = 0.15 second. With maximum RF radiation equal to 1.698 W, the Average RF Power over 30 minutes is: P_ave (worst case) at 30 minute= = 1.698 mW*1* [0.15sec/((30*60)sec)]=1698*0.000083=141 uW (3) Maximum Radiated Power Density prediction (S): To predict power density (S) at distance R=20 cm from transmitter with P_ave = 0.000141W, next formula is used: S = P_ave*Ga/(4*(PI)*R^2). For the worst of the worst worst-case prediction of power density at or near a transmitter surface that uses the non- directional antenna (Ga=1) let’s use: S = (P_ave*Ga)/((PI)*R^2) = (141uW*1)/(3.14*20cm*20cm) = 0.112 uW/cm^2 This is the impossible worst Case of the near field power density of LLB09014 transmitter. (4) Maximum Permissible Exposure (MPE) from LLB09014: AS FCC require, the maximum permissible exposure for general public in “uncontrolled situation” at 20 cm is: MPE = frequency[MHz]/1500 == 460MHz/1500 = 0.307 mW/cm^2. Compare results in (4) and (5), S=0.112uW/cm^2 < MPE=0.307 mW/cm^2 We see that LLB09014 fully complies with RF safety at a distance of 20 cm. Lazar Feldman Aclara RF 440-528-7451

James R. Pollock HEXAGRAM INC. An ESCO Technologies Company 30400 Solon Road Solon OH 44139 (440) 528-7200 RADIO-FREQUENCY EMISSIONS TEST REPORT FOR UTILITY METER TRANSMITTING UNIT Model 2009-014 FCC ID: LLB09014 December 22, 2009 Report Prepared by Agency Certification Control Technician FCC ID: LLB09014 Page 2 of 18 TEST REPORT INTRODUCTION The Hexagram Model 2009-014 transmitter is a “Meter Transmitting Unit” (MTU) designed to provide remote meter reading capability for utility meters. The transmitter is self- powered and connects to a meter with mechanical connection. On board batteries provide power. The transmitter provides a very short, intermittent radio frequency transmission to send a remote reading of the meter. A microprocessor provides timing, control and data processing functions. The built in antenna is inaccessible to the user and no provision is made for an external antenna. Two prototype units were used as test subjects for this report. This report presents the data obtained in support of an application for certification. MEASUREMENTS PERFORMED Power Output and Spurious Emissions Page 3 with test set up photographs Occupied Bandwidth Page 9 Frequency Stability vs. Temperature Page 11 Frequency Stability vs. Supply Voltage Page 12 Transient Stability Page 14 The microprocessor portions of the transceiver were also examined for radiated emissions per Part 15, and have been verified to comply with the appropriate sections of that part. The data used for verification of the microprocessor and receiver is presented in a separate report. UNITS TESTED SN – A00030 Tested for temperature and voltage frequency stability SN – A00033 Tested for power output & harmonics, occupied bandwidth and transient stability. FCC ID: LLB09014 Page 3 of 18 POWER OUTPUT AND SPURIOUS EMISSIONS Within the tuning range of 450 – 470 MHz, the transmitter portion of the Model 2009- 014 was examined at three fundamental frequencies and their harmonics. All measurements below 1 GHz were made at a 3-meter distance on the Smith Electronics open area test site located at 8200 Snowville Road, Brecksville, OH. Data pertinent to this site is on file with the FCC (Reg. #90938) and Industry Canada (File #4541A-1). The harmonic measurements above 1 GHz were made at a distance of 1 meter over a suitable ground plane. The measurements were made using the substitution method described in TIA/EIA-603-A. Tuned dipoles were used for measurements below 1000 MHz and a wave-guide antenna was used above 1000 MHz. A spectrum analyzer was used as a receiver. The transmitter was placed on a remotely rotatable, non-conducting test stand. This general set up is shown in Pictorial 1. Because of the very short transmissions of the normally operating transmitter a larger, external battery pack was connected directly to the transmitter and the transmitter was forced to transmit for 20 seconds at a 50% duty cycle to obtain these measurements. A ferrite bead was placed on the battery leads to minimize emissions that might come from the leads. With the test receiver tuned to the unmodulated signal, the transmitter under test was rotated to the position of maximum signal. The receiving antenna was then varied between 1 and 4 meters in height to again maximize the signal. Measurements were made with the antennas positioned both vertically and horizontally and the maximum signals recorded. Peak detection was used for the signals below 1000 MHz and average detection above 1000 MHz. After the maximum received meter readings were obtained for each frequency and polarity, the transmitter under test was removed from the area and replaced by a signal generator and a vertically polarized transmitting antenna. With the transmit antenna placed as close as possible to the position of the test unit, the signal generator was activated at a test frequency. With the signal detected, the vertically oriented receiving antenna was positioned vertically for maximum reception. The signal generator output was then adjusted until the received signal was equal to the previously received signal from the unit under test. These measurements were repeated for each frequency and antenna orientation and the maximum values obtained are noted in Tables 1a – 1c. In order to convert the signal generator output value to equivalent radiated power from a dipole, the following equation is used: P d = P g – cable loss(dB) + antenna gain(dB d ) where: P d is the dipole equivalent power in dBm, P g is the generator output into the substitution antenna, also in dBm, and “antenna gain” is the gain of the substitution antenna with respect to a theoretical dipole. According to 90.210(d)(3) all emissions greater than 12.5 kHz from the center of the authorized band shall be attenuated below the unmodulated carrier by 50 + 10log(P). The determined power outputs, the required harmonic attenuation as well as the attenuation for each harmonic are found in Tables 1a – 1c.
