ACLARA Technologies LLC 30400 Solon Road . Solon, OH 44139 440-528-7200 Feb 25 th 2013 FCC ID: LLB09010B4 PREVIOUS TYPE ACCEPTANCE The radio transceiver submitted (LLB09010B4) herein is used as a telemetry device for the reading of utility meters. An operationally identical device (LLB6082) was previously submitted for Type Acceptance and received a Grant of Type Acceptance on March 4 th 1998.This earlier version has been in field service since the grant was issued. The block diagram and basic circuit configuration of the new product is identical to that of the original LLB6082. As detailed in “Description of Operation, the block diagram of the LLB09010B4 is similar to LLB6082 device with difference that new device is design to accommodate new application requirements, such: • 2-way communication. • Time synchronization within a complete AMR cell. • Complete AMR cell self testing and control. • To comply with newest regulations for electrical and gas utilities. 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 LLB9975J device. STATEMENT 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 remote utility metering sought reconsideration of this provision to allow alternative showings of spectrum efficiency for low power frequency reuse systems. 2. 2The 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 MTU 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 7200 bits/sec. The system achieves spectrum (emphasis added) 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) received a grant of Type Acceptance on March 4, 1998. 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 billing, under which a customer’s utility rate varies with time of day or day of the week. Electric time-of-use billing, for example, typically requires a meter read every 15 minutes, which is not feasible without Automatic Meter Reading equipment. Frequent meter-reading is an important component of utility deregulation, because it enables new competitors to tailor service and rates to particular niche markets, profiles of demand, and competitive situations.

Power Density Calculation for Aclara 09010B4 15.247(i) Maximum Permissible Exposure The following calculations are provided to show a comparison to the Maximum Permissible Exposure (MPE) for the general population in an uncontrolled area even though the2009-010B2 MTU is categorically excluded from the necessity of a radio frequency exposure evaluation. The exclusion (2.1091) applies to Part 90 transmitters operating below 1.5 GHz with output below 1.5 Watts. Normal Field Operation of Model 2009-010B2: Frequency Range: 450 MHz – 470 MHz Transmit Power: 0.339 W (dipole equivalent power) Transmission Length: 60 mSec. Transmission Period: One transmission every 6 hours Extreme Values Used for the Calculation: Transmit Power: 0.75 W (dipole equivalent power) Transmission Length: 100 mSec. Transmission Period: Four transmissions every hour Average Power Calculation: RF exposure for the general population in uncontrolled areas is determined using transmitted power averaged over 30 minutes. The equation used in the calculation is: Pavg = P x Tx x TL/t Where Pavg is the average power, P is measured power output (mW), Tx is the number of transmission in 30 seconds, TL is the transmission length (Sec) and t is the number of seconds in 30 minutes. Therefore: Pavg = .75 W x 4 x 0.10 Sec / (30 min x 60 sec) = 0.3 W-Sec/1800 Sec = 0.16 mW Average Power Density Calculation: Average power density is calculated at a distance of 20 cm by using the following equation: S = Pavg x G/4 x π x r 2 where S is the average power density, Pavg is the average power, G is the gain of a dipole antenna and r is the distance from the transmitter. Therefore: S = 0.16 mW x 1.64/4 x 3.1416 x 20cm x 20cm = 0.44 mw/5027 cm 2 = 0.000087 mW/cm 2 = 0.052 uW/cm 2 Comparison of 2009-010B2 to MPE: The MPE for the general population in uncontrolled areas is 460/1500 = 0.3067 mW/cm 2 The average power density of the 09010B4 MTU is 0.052 uW/cm 2 , which is significantly lower than the MPE of 0.3067 mW/cm 2 .

The transceiver is self-powered and connects to the output of 1 or 2 water meters with an electrical cable. An on-board battery provides 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. The receiver can be used for upgrading firmware, requests for meter reads or other options available in the system. Special test firmware was used for testing in order to provide longer transmission than for normal operation. A prototype unit was used as a test subject for this report. The report presents the data obtained in support of an application for certification under Part 90 of the FCC rules and RSS-119- iss11 of Industry Canada.

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-C. 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 intermittent nature of the normally operating transmitter a larger, external battery pack was connected directly to the transmitter and the transmitter was forced to transmit a 30 seconds on and 30 seconds off cycle for these measurements. A ferrite bead was placed on the external 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 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 receiving antenna was positioned 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 har…
