Claim:
1. A system for transmitting a data signal, comprising: a plurality of network devices, including a first fixed network device and a second fixed network device; a network connecting the plurality of network devices based on at least a first communication carrier, the first communication carrier being a wired communication carrier; a network key generator configured to generate a network key; and a mobile transmitting device, different from the plurality of network devices, configured to transmit the network key to the first fixed network device and the second fixed network device of the plurality of network devices on a second communication carrier, the second communication carrier being a near-field communication carrier, wherein the first and second fixed network devices are configured to communicate with each other via the wired communication carrier based on a link encryption key based on the network key, and wherein the mobile transmitting device is configured to provide a selection to a user regarding whether the network key is to be generated anew by the mobile transmitting device, received from a third fixed network device of the plurality of network devices, different from the first and second fixed network devices, or retrieved from memory of the mobile transmitting device, wherein the network is based on a third communication carrier, the system further comprising: a link encryption generator configured to generate a further link encryption key for the third communication carrier based on the network key, and wherein the network devices are configured to transmit the data signal between the network devices on the third communication carrier based on the further link encryption key.
