ABB-free@home® wireless

The wireless devices of ABB-free@home provide the same level of functionality as the wired ones without the necessity of connecting a bus cable – because the communication takes place via radio frequency. The commissioning of all components is conducted through the same proven interfaces – either through an ordinary web browser or the ABB-free@home App. The possibilities remain unchanged. Wireless devices can easily be part of time programs and be operated via voice commands or remotely through myABB-Living Space.

Every free@home wireless device with a mains supply automatically works as a repeater extending the coverage of the wireless signal from the basement to the last floor, ensuring that no information gets lost.

Together with existing wired components of ABB-free@home, the new wireless devices form a seamless system: The new wireless products can either be installed completely independent, or combined with products that require a bus cable to create a mixed installation.

Best coverage thanks to a mesh network

The participants of the ABB-free@home wireless network such as the intelligent light switches, blind switches and thermostats are distributed over a large area and several floors but must still be able to reliably communicate with each other. ABB-free@home wireless devices use a mesh network topology to expand the coverage of the network to its maximum ensuring that even the switch on the last floor is reached and executes its commands appropriately and reliably.

In a mesh network all participants communicate with one another. Either directly if they are within range or indirectly via another or several nodes if they are not. The ABB-free@home wireless mesh network uses the routing process. During this process, the system access point automatically determines the most efficient way to send a message from one point in the network to the correct receiver via several nodes. This process is implemented on an ongoing basis so that the system can also react to subsequent changes e.g. in the event of individual devices failing, new devices being added or constructional changes that impair the reception.
