In this mode of operation, WiVibX sensors communicate in a network using gateways - the diagram below shows a typical insulation. Once a battery is inserted into a WiVibX sensor, it adverses to the Bluetooth network that it is available. Gateways that are within range will recognise available sensors using Just Works pairing and add them to their REST API database together with the associated RSSI value. The host application then allocates which sensors will be controlled by which gateway based on signal quality and even distribution. If a gateway loses power or goes down, the host can allocate sensors to an adjacent gateway. 

The gateway contains a web server and can be configured using a smart device (eg. tablet or phone) or via the host network. The gateway can link onto an existing ethernet of wifi network. Cellular communication will soon be supported. 

The gateway uses a REST API as its communications medium with a host. Details of the REST API are available from Icon Research for users who wish to interface a WiVibX array to their own application. 

Sensors are configured to take measurements at predetermined intervals. A typical system may be set up to take overall values, say, every hour and a spectrum once a day for base line information. The sensor spends most of its me in an ultra-low power mode but can be instructed at any me to carry out a non-scheduled ’on- demand’ measurement as it is always listening to the Bluetooth connection.
