5 Indicate if the meter reading, MIU transmission, and collector transmission intervals can be changed, and the range of choices of interval. The [COMPANY] must have a system that can update the MIU's firmware without a physical visit to each meter location. Indicate how your system accomplishes this and how these changes are propagated through electronic communications with the MIU. Describe the procedure. Indicate whether a change in reading or transmission interval is or can be programmed to reset automatically, and indicate any impacts on battery life. System Capacity [COMPANY] requires a system with data-logging capacity built within each MIU and collector. Describe the capacity of each system component in terms of the number of meter readings stored (in total and per meter) and/or the number of meter readings that can be transmitted or received in each time interval. What happens as capacity is approached? What happens when it is exceeded? (For example, does new data overwrite old data?) Describe any provisions in the system for archiving old meter reading data. Each MIU must be capable of storing a minimum of three hundred sixty-five (365) days of hourly usage information. Describe the procedure for retrieving meter data from the data collection unit (DCU) in case of power or backhaul outage. The [COMPANY] requires a system that will not require a visit to each meter for either visual or drive-by reading should either of the above events occur. Grouping of Meters [COMPANY] is looking for a system with the capability of separating customers by account type. Briefly indicate any capabilities or limitations of the system to separate meters into groups (e.g., by routes, types of customers, billing cycles) for reading. Include a description of how the system can be used to gather synchronized readings from a grouping of meters (such as all meters within one pumping district). Consumption Profiling [COMPANY] requires multiple readings, in the form of a twenty-four (24)-hour data log showing hourly information, be transmitted with the daily transmission received from each MIU to monitor and profile water-consumption patterns from a particular meter or group of meters. Describe the range of intervals and how this is accomplished. Are such short interval readings stored in memory at the MIU or DCU, transmitted all at once, or transmitted as they are received? Provide a table of the interval of readings and the number of readings stored. Describe any impact of the use of this capability on battery life. Radio Communication Band [COMPANY] requires that the radio frequency used between the MIUs and the collectors must operate in the 902 MHz to 928 MHz open frequency band and operate in a frequency-hopping spread spectrum (FHSS) mode without the need for a Federal Communications Commission (FCC) license to operate the system, as is consistent with LoRaWAN network deployments. Systems requiring an FCC license or dedicated bandwidth will not be considered. Indicate which radio frequencies are used for interactions between the MIUs and collectors. Data Transmission Accuracy and Security The system must include provisions to ensure data transmission accuracy (for example, error checking), security (for example, encryption), and immunity from outside (electromagnetic) interference, as well as fading and other forms of signal degeneration or attenuation (such as multi-path fading) to prevent accidental loss or interception of customer or meter reading data. Describe how this is accomplished. Do not describe in this section the security system associated with controlling user access. Do the MIUs and DCUs send a confirmation message back through the communication channel to ensure that the readings are received?
