Abstract: A utility meter includes a metrology core, a short-range radio configured to communicate wirelessly over a local area mesh network, a long-range radio configured to communicate wirelessly over a wide area network and a controller that checks a performance of the local area mesh network against one or more predetermined performance criteria. When the performance of the local area mesh network meets a set of one or more predetermined performance criteria, the utility meter communicates a first set of the information to the head-end system using the short-range radio. When the performance of the local area mesh network does not meet the set of one or more predetermined performance criteria, the utility meter communicates a second set of information to the head-end system using the long-range radio.

Abstract: Methods and systems for integrating communication devices into an industrial wireless system. A communications interface can be enabled on a field device access point from a user interface associated with a wireless device manager. The field device access point is configured to enable registers to read from different slave devices at different speeds and different data types. A proxy object can be implemented, which communicates with RTU (Remote Terminal Unit) devices and a cache can be implemented to store read data from different RTU slave. The read data is then periodically published to the wireless device manager through a wireless interface, thereby permitting the RTU devices or TCP devices to connect to the industrial wireless network using the field device access point.

Abstract: A method includes receiving data from multiple wireless field devices using multiple wireless communication protocols. The method also includes normalizing the data from the wireless field devices using one or more templates associated with the wireless field devices. The method further includes transmitting the normalized data in a unified format.

Abstract: A method includes receiving link quality information associated with multiple wireless connections in a wireless network. The method also includes identifying at least one asymmetric communication path in the wireless network using the link quality information. The link quality information could include a statistical value for each of the wireless connections. Identifying the at least one asymmetric communication path could include identifying a first and a second of the statistical values associated with a first and a second of the wireless connections, respectively, and determining whether a difference between the first and second statistical values exceeds a threshold. The method could further include applying a heuristic to indicate that the first and second wireless connections do not form an asymmetric communication path even if the difference between the first and second statistical values exceeds the threshold.
