Abstract: Technologies generally described herein relate to connection of a mobile device to a base station in a wireless communication system. Example mobile devices may include a receiver, a data communication module, a switch module, and a signal consolidator. The receiver may be configured to receive, from a base station through a cellular band, a first control signal including control information regarding the base station. The data communication module may be configured to communicate with the base station through a non-cellular band. The switch module may be coupled to the receiver and to the data communication module, and configured to determine that a power level of the first control signal is higher than a first threshold value and activate the data communication module in response to the determination. The data communication module may be further configured to receive a second control signal including the control information from the base station through the non-cellular band. The signal consolidator may be coupled to the receiver and the data communication module, and configured to obtain the control information regarding the base station from at least one of the received first control signal or the received second control signal.

Abstract: Technologies are generally described for phase measuring profilometry (PMP) using structured light patterns based on orthogonal frequency division multiplexing (OFDM). In some examples, a composite structured light pattern generated using OFDM may be used to illuminate a surface of interest. The surface may reflect a phase-distorted version of the structured light pattern, and the phase-distorted structured light pattern may be processed to recover image and/or height information about the surface. In some embodiments, fast Fourier transform schemes may be used to generate the composite structured light pattern and process the phase-distorted structured light pattern.
