KNX

KNX is a open protocol in the WHAN category that was developped for the domotic sector. The main goals of the developpement was to have a flexibility and adaptability to future developments, to save time by making the setup more easier and limit energy consumption. Indeed, a KNX installation can be easily adapted to new applications and is easily extendable. New components can be easily connected to the existing bus installation. Furthermore, KNX gives complete interoperability allowing mixing and matching of components without requiring special drivers or applications. All certified KNX products must display the KNX logo and are recorded by the KNX Association. Also, it uses a FSK modulation with a Manchester coding. It's also noticable that KNX can be used with a cable, and in this case the range can be up to 3 km.
