Abstract
The present invention relates to a receiver-centric transmission system for IoT systems, such as lighting networks, with combo protocol radio chips that share a single radio front-end for two or more transmission protocols of different network technologies while preventing unacceptable performance degradations in one or both protocol modes. The receiver-centric approach allows implementation of two networks with acceptable performances on one single radio chip per node rather than requiring two radio chips per node.
Claims15
A network node for use in a network, the network node configured to transmit or receive either in a first communication mode using a first network technology or a second communication mode using a second network technology on a time-sharing basis according to a predetermined duty cycle, the network node comprising an apparatus for controlling transmission of a network node in a network, wherein the apparatus comprises:
- a determination unit for determining a preferred communication mode of a target node of the transmission, the preferred mode being a communication mode of the target node, out of the first and second communication mode, that the target node uses most;
- and
- a selecting unit for selecting one of the first and second communication modes for the transmission to the target node based on the determined preferred communication mode of the target node, wherein the preferred communication mode is based on information about the target node, which information is retrieved from the target node directly, indirectly from a further node or gateway, or may result from pre-configured rules.
A method of controlling transmission of a network node in a network, the network node being configured to transmit or receive in a first communication mode using a first network technology and in a second communication mode using a second network technology on a time sharing basis according to a predetermined duty cycle, wherein the method comprises:
- determining a preferred communication mode of a target node of the transmission, the preferred mode being a communication mode of the target node, out of the first and second communication mode, that the target node uses most;
- and
- selecting one of the first and second communication modes for the transmission to the target node based on the determined preferred communication mode of the target node,
- wherein the preferred communication mode is based on information about the target node, which information is retrieved from the target node directly, indirectly from a further node or gateway, or may result from pre-configured rules.
