TMU devices use the Sigfox network to transmit temperature profile information to the LinkThru software platform. There is no requirement to integrate or interfere with any on-site/local IT or networking systems.
The low power required to send messages via Sigfox optimises TMU battery life. Security of TMU wireless communications is ensured through an array of features, including anti-replay, message scrambling and message sequencing.
WND-UK, the UK’s Sigfox network operator, are deploying Britain’s first dedicated Internet of Things (IoT) network with roll-out scheduled to provide 95% signal coverage of the UK population.
