On-Demand 1.2 Overview2 Technical Brief Introduction The Aclara RF™ network is an advanced metering infrastructure or AMI that allows for meter readings to be transmitted directly to a utility along with various system performance and diagnostic information. It allows for unmanned reading of water and gas meters. It is currently deployed in more than 700 utilities worldwide. The three major components of the Aclara RF™ Automated Metering Infrastructure system are: Meter Transmission Units (MTUs) - These are connected to the meter, whether wired to it for water, or physically attached for gas. They take hourly readings from the meter and transmit them via radio frequency on a regular basis. Each meter in the system will have an MTU. Data Collector Units (DCUs) - These are installed in the field to collect readings from nearby MTUs. The DCU performs some treatment and consolidation of these readings and transmits the, typically via cellular service, to the Network Control Computer. AclaraONE - This is the head end, the brain of the system and its command center. It collects all the data from the DCUs in the system, stores it, and uses a web portal to present that data in usable form for the utility. MTUs Aclara’s series 3000 devices connect to the meter, record readings hourly, and store them in memory. They can hold 12 readings in memory, and every 6 hours they transmit those readings via radio frequency to nearby DCUs. Since the MTU can hold no more than 12 readings, each hour a new reading is added to memory and the oldest reading, the one that is 13 hours old, drops off. Because MTUs transmit 12 readings every 6 hours, there is redundancy in the readings transmitted. The first 6 readings from the 6:00 a.m. transmission will be the last 6 readings in the noon transmission. By the 6:00 p.m. transmission, those 6 readings will have been replaced by 6 newer readings. This redundancy means that if a transmission fails to reach the DCU for whatever reason, the readings still have a second chance in the next transmission. Duplicate readings are filtered by the DCU, so only a single hourly reading is transmitted to AclaraONE. Water and gas MTUs differ slightly in the way they connect to the meter. Gas MTUs are attached to the face of the gas meter, and consequently cannot be repositioned. (Meter-specific gas meter installation instructions are also available on Aclara Connect.) A water MTU is connected to the meter register by means of a three-wire cable. Because water meters may be installed indoors in cold climates, and either outdoors or in pits in warm climates, the length of the cable allows for some flexibility in placement of the MTU for optimum radio signal propagation.

Justification The model 2019-006 radio transceiver submitted is used as a part of a utility meter reading system. The 2019-006 transmitter sends data with a 2GFSK modulation at a rate of 7232 bps. The emissions designator is 9K66F1D. As the 2019-006 does transmit at 7232 bps with a bandwidth of 7.4 kHz, it is capable of supporting a minimum data rate of 4800 bits per second per 6.25 kHz of bandwidth.

Authorized Agent: Radiometrics Midwest Corporation (815) 293-0772 RF Exposure FCC ID: LLB2019006 This calculation is based on the highest EIRP possible from the EUT considering maximum power and antenna gain. The highest output power of the EUT is 0.794 W and the max gain of the antenna is 3 dBi. There is a firmware control duty cycle. The firmware is set to limit duty cycle at 40% duty cycle or less in any given 6-minute period. In most cases, the duty cycle is much less than 40%. For all calculations, 40% will be used as a worst-case in any given 6-minute period, as this is a worst case. 1.0 RF EXPOSURE PER FCC 1.1310 MHz Max Power dBm Max Ant Gain dBi Duty Cycle % EIRP Watts (S) GP Limit mW/cm^2 Declared Minimum seperation Distance (cm) EUT power Density mW/cm2 Result 450 29.00 3 40 0.634 0.300 20.0 0.126 Pass 460 28.85 3 40 0.612 0.307 20.0 0.122 Pass 470 28.90 3 40 0.620 0.313 20.0 0.123 Pass Notes on the above table: a.
