Transmission route

Wired or cable network – there are systems that either need their own BUS-cable, such e.g. KNX, LON or using an existing cable infrastructure. Commonly used infrastructures are the network supply (so-called powerline) or LAN networks. Coax cable networks are less used. In the case of shared systems, the respective mutual influence must be taken into account, whatever may be a source of an error. Of course, independent BUS networks always offer the highest level of system security, but they are also usually more expensive.

Wireless transmission – there are quite different technologies. So there is transmission via sound waves (acoustic), well known infrared transmission (usually as remote control) or very widespread transmission via radio. Different radio areas are used by radio, e.g. in the range of 433 or 868 MHz, the 2.4 or 5 GHz WLAN, various Bluetooth systems and standards, the DECT system (known from cordless telephones) and various other radio systems. Each wireless system has different propagation properties, but they all have one thing in common - you cannot see the transmission route. So troubleshooting - if nothing received - is not always simple. Security can be achieved by encryption and a reconfirmation of the transmission.
