The invention discloses a method for fast detection scan of NB-IoT signals in networks. The object of the invention to provide a scanning procedure which is reliable and very fast in order to reduce the search time and hence the power consumption will be solved by a method for fast detection scan of NB-IoT signals in a network by applying a higher sampling rate than 240 kHz and observing a received signal at a receive bandwidth around a magnitude wider than the NB-IoT signal bandwidth of 180 kHz, wherein a set of 2M+1 NB-IoT signals each having a different E-UTRA absolute radio frequency channel number (EARFCN) can be observed simultaneously, whereas M is a natural number and 2M+1 indicates the number of concurrently observed channels.

A circuit of a node in a radio network and method for transit time measurement between a first node and a second node of a radio network is provided. A frame is transmitted by the first node, wherein the frame requires an acknowledgment of reception by the second node. A first point in time of the transmission of the frame is established by the first node by a time counter. The frame is received by the second node at a second point in time. The acknowledgment is transmitted by the second node to the first node at a third point in time, wherein the third point in time depends on the second point in time by a predetermined time interval between the second point in time and the third point in time. A fourth point in time is established by the first node by the time counter when the acknowledgment is received. The transit time or the change in transit time is determined from the first point in time established by the time counter and from the established fourth point in time and from the predetermined time interval.

A set of circuit carriers includes a number of N&#x2267;1 circuit carriers, each of which has an upper side, an underside opposite from the upper side, a distinctive structure, and a conductor structure on the upper side. Each of the circuit carriers is populated by: determining a first relative position between the distinctive structure and the conductor structure; picking up the circuit carrier by a pickup of a lifting and positioning unit; determining a second relative position between the lifting and positioning unit and the distinctive structure of the circuit carrier picked up by the pickup; and populating the circuit carrier with one or more components while taking the first relative position and the second relative position into account.

A method for producing a semiconductor module includes providing an adhesion carrier and a plurality of circuit carriers. The adhesion carrier has an adhesive upper side and a lower side opposite the adhesive upper side. Each of the circuit carriers includes a ceramic carrier and an upper conductor layer applied to the ceramic carrier, and a circuit carrier lower side. By placing the circuit carriers onto the adhesive upper side, the circuit carrier lower side of the circuit carriers contacts and adheres to the adhesive upper side, so that a quasi-panel is formed, in which the circuit carriers are processed while preserving the quasi-panel and can then be removed from the adhesive upper side.

A method and device is provided for detecting data symbols in a received radio signal. Each data symbol is allocated transmit-side a symbol value-specific PN sequence of successive PN chips in the chip clock, and the allocated PN sequences are offset QPSK modulated. The method for incoherent detection includes converting the received radio signal into a complex baseband signal sampled in the chip clock, generating a demodulated signal by differential demodulation of the complex baseband signal, calculating correlation results by correlating the demodulated signal with the derived sequences, and deriving the values of the data symbols by evaluating the correlation results. Each derived sequence is assigned to a PN sequence allocable transmit-side and includes derived chips, whose values correspond to a logic linking of particular PN chips of the PN sequence allocable transmit-side that is assigned the derived sequence.
