Abstract (en)
[origin: WO2016004997A1] An OPC UA client is rendered able to consolidate the transmission and reception times so as to extend the antenna amplifier pause times. In so doing, it is meant, without this requiring a change to the OPC UA protocol, to send exclusively at defined focusing times. No sending is meant to be necessary between these times. A set of requests is sent to the server at a particular time. The client then enters reception mode. The server handles the received requests periodically over time. When almost all requests have been handled, a new set of requests is made to the server again. Between these focusing times, the transmitter of the client/mobile device can be switched off completely and hence save power. The method presented here is totally compatible at all levels of communication (TCP stack, WLAN).
