Abstract: Radio frequency communication method for wirelessly transmitting data packets between two communication nodes of a communication network, the method comprising the steps of generating a data packet including payload data and a first data check value a, transmitting the data packet from the first node to a second node; and determine whether the data packet is transmitted correctly by calculating a second data check value based on the received payload data and comparing the second data check value to the first data check value to; if the data packet is received correctly, transmitting from the second node to the first node an acknowledgement packet including a first acknowledgement check value wherein the first acknowledgement check value provides stronger assurances about data integrity of the received payload data than the first and second data check values; and at the first node, calculating a second acknowledgement check value based on the original payload data, and determining whether the data received at the second node matched the data originally sent from the first node.

Abstract: The present invention describes a smart metering device being part of an advanced metering infrastructure. The smart metering device might comprise one or more sub devices such as: metering devices, actuator devices, sensor devices etc. The smart metering device includes a valve arranged to limit the delivery of a utility to the consumer. Moreover the smart metering devices includes a communication device including a transmitter and a receiver for wireless communication with a collector, utilizing a listen after talk mechanism to perform a two way communication to the head end system through a collector. The presented invention is especially beneficial for battery supplied smart metering devices. The advanced metering infrastructure will provide a given service level for communication between the meter and the head end system. The service level will be changed dynamically in order to meet the adequate service level at all times.

Abstract: The present invention relates to a device and a system for transmitting data messages which can be received by different types of receivers. A device and system are disclosed where data transmissions are based on data messages (2) comprising two parts, a first part (20) being encoded in accordance with a communication protocol, such as the wireless MBus protocol, and a second part (21) which comprises error-correcting information for enabling a receiver device to correct errors in the data message (2), such as parity information related to turbo coding. The first part (20) forms an independent sub data message which can be received independently of the content of the second part (21). The sub data message can be received as is within a first communication range (6), and the entire data message can by virtue of the error correction information, and subsequent error correction, be received within a second longer communication range (7).

Abstract: A consumption meter (M1) arranged to determine a consumed quantity of a utility at the consumer site. The meter (M1) has a communication unit with a transmitter and a receiver arranged for communication via a network, preferably an RF network. The meter can autonomously transmit data frames (DF) in accordance with a set of transmission parameters, e.g. data frames with data indicative of a consumed quantity. The meter can receive, within a limited time window (TW) following transmission of said data frame (DF), an acknowledgement frame comprising link data indicative of receipt of said data frame by an associated collector which has received the data frame (DF). Finally, the meter can adjust the set of transmission parameters for transmission of a subsequent data frame (DF) in response to said link data.

Abstract: The invention relates to a system of consumption meters (2) arranged in a communication network, where program data of the consumption meters can be updated via the communication network. A data collector (3) is arranged for updating the program data of a group of consumption meters over the network. This is performed by establishing a dedicated update session to each consumption meter of the group of consumption meters, and transmitting addressed update program segments to consumption meters in session. During the update session with a given consumption meter, any other consumption meter which is within communication range (8) will, if it receives the update segment, store it even though the segment is addressed to another meter. In an update session of a next meter, only segments not already stored from a previous session to another consumption meter are transmitted to the next meter.
Abstract translation: 本发明涉及一种布置在通信网络中的消费量表（2）系统，其中可以经由通信网络更新消费计量表的程序数据。 数据收集器（3）被布置用于通过网络更新一组消耗计量器的程序数据。 这是通过建立一组消费计量器的每个消耗计量器的专用更新会话，并将寻址的更新程序段传送到会话中的消费表。 在与给定的消耗计量表的更新会话期间，在通信范围（8）内的任何其他消耗计量器将在其接收到更新段时将其存储，即使该段被寻址到另一个仪表。 在下一个仪表的更新会话中，只有尚未从先前会话存储到另一个消耗计的段已被传送到下一个仪表。

Abstract: A wireless communication link management method includes sending data in a primary uplink data frame from the measuring device (7) to the data collection unit (5) via a primary channel. After sending, the measuring device provides a time-limited primary access opportunity (AO) for receiving a link management downlink frame. A primary signal quality is evaluated. A secondary uplink frame is sent from the measuring device via a secondary channel. A time-limited secondary access opportunity for receiving a link management downlink frame is provided. Secondary signal qualities are evaluated. One among the primary access opportunity and the secondary access opportunities is selected for sending a link management downlink frame from the data collection unit to the measuring device depending on the signal qualities. The associated channel is used as the primary channel for sending data in a primary uplink data frame from the measuring device to the data collection unit.
