A method for distance measurement by means of an active optical sensor system is disclosed, comprising: an initial pulse sequence with an initial frequency spectrum, which corresponds to a frequency comb, is generated using a laser source. Based thereon, a first pulse sequence and a first reference pulse sequence with a first frequency spectrum, which corresponds to a first part of the frequency comb, as well as a second pulse sequence and a second reference pulse sequence with a second frequency spectrum, which corresponds to a second part of the frequency comb, are generated. A first distance of the object is determined using a first heterodyne measurement based on the first reference pulse sequence and reflected portions of the first pulse sequence and a second distance is determined using a second heterodyne measurement based on the second reference pulse sequence and reflected portions of the second pulse sequence.

A system for providing a wireless communication with a mobile device includes a plurality of frontends coupled to a central point, each of the plurality of frontends configured to provide for a wireless communication with the mobile device, and a network controller coupled to the central point. The network controller includes a data flow control device configured to control the data flow between each of the frontends and the central point, the data flow control device being configured to operate responsive to a control signal from the network controller, the control signal indicating which of the plurality of frontends serves the mobile device.
