Commission devices (1) comprise first transmitters (11) for transmitting activation signals to load devices (2-6), and second transmitters (12) for transmitting numbers of challenge signals to activated load devices (2) that respond by sending back a response signal per challenge signal to the commission devices (1). The commission devices (1) further comprise first receivers (13) for receiving the response signals and controllers (14) for determining time-intervals present between transmissions of the challenge signals and receptions of the response signals. The controllers (14) derive absolute or relative positions of the load devices (2-6) from analyzes such as statistical analyzes of the time-intervals. Load devices (2-6) comprise second receivers (21) for receiving the activation signals and third receivers (22) for receiving the number of challenge signals and third transmitters (23) for sending back the response signals to the commission devices (1). The load devices (2-6) may further comprise loads (26).

A method and system for wireless communication between a moving vehicle and a remote server through at least one external mobile network are disclosed. The at least one exterior mobile network provides at least two concurrently useable data links. The method includes: providing at least one router in the moving vehicle for receiving and transmitting wireless data communication to and from a stationary communication server outside the moving vehicle through the at least one exterior mobile network; evaluating the quality of the data links on a host layer by repeatedly sending requests arranged to trigger a determinable automated response to the stationary communication server via the data links, and measure the time until the triggered automated responses are received; and assigning data streams to the data links at least partly based on the evaluated quality.

A switching element that is at least partially implemented in one or more printed wiring boards (PWBs). A plurality of inputs and a plurality of outputs may be integrated into the PWB(s). In some embodiments, a plurality of contact bars may also be comprised in respective contact bar pockets bounded at least partially ab at least one of the PWB(s). The switching element is selectively operable in first and second states, the first state in which at least one contact bar couples one of the plurality of inputs to one of the plurality of outputs such that an analog signal input to the respective input is routed to the respective output and the second state in which at least one contact bar is held in an off state.
