Abstract: Among network devices for use within a wireless communication network, a transmitting network device is configured to transmit to a receiving network device via a control channel one or more control signals for configuring the receiving network device for a characterization of at least one of the transmitting network device and the receiving network device and/or for a characterization of one or more communication channels between the transmitting network device and the receiving network device.

Abstract: An apparatus comprises an antenna array comprising a plurality of antennas. The apparatus comprises a communication interface for receiving a control signal. The apparatus is configured to form a first radio frequency beam in accordance with a predetermined test case independent from the control signal using the antenna array. The apparatus is configured to form a second radio frequency beam that is different from the predetermined test case responsive to instructions contained in the control signal.

Abstract: A matrix switch comprises a number of switching elements configured in a matrix and a controller that operates to dynamically select one or more signal routes via the switching elements. The matrix switch can operate to dynamically route multiple signal routes between antenna ports to one or more transceiver ports, transmitter ports, receiver ports or termination ports. The controller can select the signal routes based on a set of criteria, which can include one or more use conditions, radio resource conditions or propagations conditions.

Abstract: An antenna measurement range and a method of calibrating same is proposed which at least substantially reduces the effects of echoing or multi path. The method of calibrating the range comprises the steps of: generating and radiating a training signal; receiving the radiated training signal and comparing the received signal with the expected signal; determining a set of equalizer coefficients to be used in these circumstances to eliminate or minimize the error between the expected training signal and the received signal; and storing the set of equalization coefficients and associating them with the rotational or translational position of the antenna under test so that the coefficients can be applied to subsequent radiation pattern measurements. In one embodiment, the measurement nodes are dispersed in a three dimensional array about the antenna under test and a set of coefficients arrived at for each node to be applied to the subsequent radiation pattern measurements.

Abstract: A device for printing a web moving in a direction (YB), wherein ink jets print on the web a printing width across its direction (YB) of advancement while traversing a printing station. The printing station includes one or more printer heads that produce ink jets over a footprint width which is narrower than the intended printing width over the web. One or more shaping elements bestow on the web traversing the printing station a V-shape so that the web is at least locally oriented oblique to the linear array of nozzles that project the ink. The ink from the printer head(s) is thus printed over the intended printing width of the web.
