CELLULAR CARRIER SELECTION BASED ON PERFORMANCE PARAMETERS
Various embodiments disclose a connectivity management service that identifies an estimated capacity for a first network sector corresponding to a first carrier network, measures average latency for the network sector based on endpoint devices that communicate using the network sector, determines an actual available capacity for the network sector based on the average latency and the estimated capacity, and transmits instructions for an endpoint device of the endpoint devices to change from the first network sector to a second network sector.
A single-transducer fluid meter is adapted to measurement the flow of a fluid (e.g., water or natural gas). A transducer sends an ultrasonic signal within a flow pipe through which the fluid flows within the fluid meter. In the example, the ultrasonic signal is reflected twice, thereby traveling in a triangular path that starts and ends at the transducer. A time-of- flight of an ultrasonic acoustic signal is measured. The time-of-flight starts when an electrical signal excites the transducer, and ends when the acoustic signal returns to the transducer. The time-of-flight of the ultrasonic signal can be used (with the speed-of-sound of the fluid) to calculate a flowrate of the fluid. In a first example, a faster flowrate of the fluid can result in a shorter time-of-flight (e.g., if the ultrasonic signal moves with the fluid flow). A slower flowrate of the fluid can result in a longer time-of-flight.

METER WITH MIXTURE DETECTION AND METROLOGY COMPENSATION
The disclosure describes techniques for a fluid meter or other device to compensate for errors in ultrasonic flowrate measurement. In an example, a fluid meter measures a fluid (typically water) having an additive or impurity, such as glycol, or salt, respectively. When metering such a fluid, ultrasonic fluid metering devices may produce slightly inaccurate results. Accordingly, an adjustment factor, based on the fluid, the additive or impurity, and the temperature, would be desirable. In an example, the fluid (e.g., water and an additive or an impurity) and the temperature of the fluid are determined. The speed of sound through the fluid is measured, and mapped to a concentration (e.g., a percentage of the additive or impurity). The concentration is mapped to a viscosity, and the viscosity is mapped to the adjustment factor. The adjustment factor is used to adjust (or correct) a flowrate measured by an ultrasonic metrology device.

Techniques for sharing resources between a radio access technology (RAT) modem (e.g., an LTE modem) and a processor-based radio (e.g., a software-defined radio) are described. In an example, operation of the RAT modem establishes an extended discontinuous reception mode (eDRX) cycle with a cellular system. The RAT modem sends eDRX scheduling information, that is based at least in part on the eDRX cycle, to the processor-based radio. Operation of the processor-based radio identifies paging opportunities (POs) of the eDRX cycle, based at least in part on the eDRX scheduling information. Operation of the processor-based radio manages usage of shared resources (e.g., transmit and receive amplifiers, digital signal processing elements, memory devices, elements of physical layer(s), and/or antenna(s), etc.). The managing may be based at least in part on the identified POs. The managing avoids conflicts between the RAT modem and the processor-based radio over the shared resources.

NETWORK PROTOCOL FOR BATTERY POWERED DEVICES WITHIN A WIRELESS NETWORK
Techniques for a network protocol for devices and nodes withing a wireless network include a method that includes receiving, by a first node included in a subtree of nodes within a wireless network, a first address list from a second node, the second node being a parent of the first node in the wireless network, wherein the first address list includes addresses of nodes along a path between the second node and a root node of the subtree of nodes; and in response to an address of the first node being included in the first address list, disconnecting, by the first node, from the second node.
Detection and measurement of transient pressure events in a water (or other fluid) supply system are described herein. A water meter may have upstream and downstream piezo transducers that measure flowrate and overall water consumption. The transducers operate for very short periods (e.g., milliseconds) at intervals (e.g., a second). During the substantial periods during which the piezo transducers are not measuring flowrate, one of the transducers may be used to detect transient pressure events. An output signal of the transducer is compared to a pressure threshold to determine if a transient pressure event has occurred. The comparison may include either a number of times that the threshold was exceeded during a time period, or the time that the threshold was exceeded during the time period. If a transient pressure event was detected, a dedicated transient event sensor can be turned on to better assess the situation.

Techniques for allocating a load capacity to on-site smart sensors coupled to distributed energy resources (DERs) are described herein. For example, a primary smart sensor may receive, from a utility supplier (e.g., which may include a substation), a maximum load constraint associated with a network of smart utility sensors in an autonomous routing area. The maximum load constraint may be a maximum load and/or maximum capacity that the network of smart utility sensors may collectively operate with by a transformer carrying the load. In some examples, the primary smart sensor may receive utility data from the smart sensors and may determine a total transformer load associated with the transformer that is providing power to the network of smart utility sensors based at least in part on the utility data.
Techniques for detecting blockage of a utility meter or other networked device are described. The blockage may be natural, e.g., snow, ice, and/or biomass. The blockage (e.g., aluminum foil) may be an intentional attempt to tamper with the device. In both cases, the blockage material may interfere with radio frequency (RF) communications of the networked device with other devices on a network. For example, snow, ice, biomass, and/or aluminum foil may prevent a networked utility device (e.g., a metering device) from reporting consumption data to a data-collecting device. Blockage may be detected based at least in part on the use of optical sensors and/or RF sensors. In one example, an out- going optical signal (e.g., infrared light) may be reflected off blockage material and the reflection may be received and processed. In a further example, an in-coming RF signal may be attenuated and/or frequency-shifted thereby revealing aspects about the blockage material.

CAPACITIVE ELECTRICAL CONDUCTIVITY SENSOR INTEGRATED IN A WATER METER
A capacitive electrical conductivity sensor is integrated into a water meter. The sensor is used to determine water conductivity, which may be used to determine water quality. A model of a capacitor, a flow of water, and a plastic conduit used to conduct the flow of water passing through a water meter is defined. The model may include a circuit having a constant phase element (CPE) connected to a resistor Rb and a capacitor Cb in parallel. An input signal may be applied to the actual capacitor (not the model) over a range of frequencies. Current flow associated with several frequencies may be used to identify values of Q0 and alpha of the CPE of the model. A value for the resistor Rb is identified using values obtained from measurements. A conductivity of the flow of water may be derived using input values comprising Rb, and the values of Q0 and alpha of the CPE of the model.

Detection and measurement of transient pressure events in a water (or other fluid) supply system are described herein. A water meter may have upstream and downstream piezo transducers that measure flowrate and overall water consumption. The transducers operate for very short periods (e.g., milliseconds) at intervals (e.g., a second). During the substantial periods during which the piezo transducers are not measuring flowrate, one of the transducers may be used to detect transient pressure events. An output signal of the transducer is compared to a pressure threshold to determine if a transient pressure event has occurred. The comparison may include either a number of times that the threshold was exceeded during a time period, or the time that the threshold was exceeded during the time period. If a transient pressure event was detected, a dedicated transient event sensor can be turned on to better assess the situation.

Techniques for network management are described herein. In a network environment, such as a utility system (e.g., an electrical grid, a water supply system, a natural gas supply system), networked devices are used to upload data to a data-collector (e.g., central office server(s)). The networked devices can be grouped. In the example of an electricity grid, networked devices (e.g., smart electricity meters) can be grouped according to a transformer to which all of the members of the group are attached. To reduce network data traffic, data packet collisions, transmission retries, and power consumption, a "spokes-meter" may be selected. The spokes-meter is configured to accept data from other members of the group and to forward that data to the data-collector. The spokes-meter acts as a relay for other members of the group.

Techniques for synchronizing devices on a high-latency network include obtaining a timestamp (e g., time-data, such as date-and-time-data) from a secure source in the network. It is determined if a global network satellite system (GNSS) signal timestamp is available. Such a timestamp may be more accurate than the network timestamp due in part to latency. If the GNSS signal timestamp is available, it is validated if it is within a first threshold time period from the timestamp. If the GNSS timestamp is not validated, it is determined if a cellular network timestamp is available from a cellular network. If the cellular network timestamp is available, it is validated if it is within a second threshold time period from the timestamp. An onboard clock is set based at least in part on a time-source that could be validated.
