A method for establishing a free-space data transmission channel between movable and/or spatially fixed network nodes. Dynamic position information is collected regarding movable network nodes and static position information relating to spatially fixed network nodes. Specific and node-dependent parameters for the fixed network nodes is collected, based on collected dynamic and static position information. A prioritization list is created of the fixed network nodes. Checking occurs, for the network node having the highest priority of the multiplicity of movable or spatially fixed network nodes in the created prioritization list, which of a selection of movable or spatially fixed network nodes are possible for setting up a directional free-space data transmission channel with the network node having the highest priority of the fixed network nodes. A directional free-space data transmission channel is set up.

An active display (102) can be used in a theatre environment (100) in which content to be displayed by the active display (102) can be delivered wirelessly using emitters (118). The active display (102) can include tiles (104a-104d) with detectors (106a-106d) that can detect the wireless signals. The active display (102) can include circuitry that can interpret instructions from the wireless signals for controlling the output (108a-108d) of pixels on the tiles.

Amplitude-modulated (AM) signals spanning a spatial wide area can be efficiently detected using a slowly scanning optical system. The system decouples the AM carrier from the AM signal bandwidth (or carrier uncertainty), enabling Nyquist sampling of only the information-bearing AM signal (or the known frequency bandwidth). The system includes a staring sensor with N pixels (e.g., N>10.sup.6) that searches for a sinusoidal frequency of unknown phase and frequency, perhaps constrained to a particular band by a priori information about the signal. Counters in the sensor pixels mix the detected signals with local oscillators to down-convert the signal of interest, e.g., to a baseband frequency. The counters store the down-converted signal for read out at a rate lower than the Nyquist rate of AM signal. The counts can be shifted among pixels synchronously with the optical line-of-sight for scanning operation.
