The RC1180-KNX2 from Radiocrafts AS targets building automation applications and claims to be the world’s first RF module with a complete embedded KNX-RF multiprotocol stack. KNX-RF Multi is an extension of the European standard for building automation with extra redundancy and increased reliability. The embedded protocol is backward compatible with KNX-RF 1.1 and KNX Ready and can be used with unidirectional and bidirectional devices.
The new module is intended to be used with sensors, actuators and other home and building automation devices. It operates in the 868 MHz band using Listen Before Talk (LBT) and frequency agility to reduce collisions. Up to five frequencies are scanned and selected automatically. A single receiver can be linked with up to 64 transmitters, enabling very large RF networks. [via]
