Abstract
A communication system and method to be used in a system having a plurality of sensors and/or controllers. The communication system comprises a main gateway (GW) connected to a first controller of the system, the main GW wirelessly connectable to a management center of the system via the Internet or a cloud system, and at least one satellite GW connected to at least one second controller of the system, the at least one satellite GW connected to the main GW via a wireless local area network (WLAN).

A communication system to be used in a system having a plurality of sensors and/or controllers, the communication system comprising:
- a main gateway (GW, 20a) connected to a first controller (10) of the system, the main GW (20a) connectable to a management center (50) of the system via the Internet or a cloud system (40);
- and
- at least one satellite GW (20b-20e) connected to at least one second controller (30a-30g, 7a, 7b) of the system, the at least one satellite GW (20b-20e) connected to the main GW (20a) via a wireless local area network (WLAN).
A method of performing communication in a system having a plurality of sensors and/or controllers, the method comprising:
- receiving (S43), by a satellite gateway (GW, 20a), data from at least one second controller (30a-30g, 7a, 7b) of the system;
- transferring (S47), by the satellite GW (20b-20e), the data to a main GW (20a) connected to a first controller (10) of the system, the satellite GW (20b-20e) connected to the main GW (20a) via a wireless local area network (WLAN);
- and
- transferring (S49), by the main GW (20a), the received data to a management center (50) of the system via the Internet or a cloud system (40).
