  • Patent number: 8730848
    Abstract: A repeater (1) particularly suitable for a time-division duplex transmission of communication signals is provided. The repeater (1) comprises a master unit (2) for communicating with a base station (3) of a wireless network, at least one remote unit (4) for communicating with a network terminal, as well as a waveguide (11) connecting the remote unit (4) with the master unit (2) for transmitting the communication signals in an uplink direction (6) from the remote unit (4) to the master unit (2) and in a downlink direction (5) from the master unit (2) to the remote unit (4). Both the master unit (2) and the remote unit (4) comprise one switch (19, 20) each for changing over the signal transmission between uplink direction (6) and downlink direction (5).

  • Patent number: 8681916
    Abstract: A master unit and a remote unit is provided for a multiband transmission system for distributing and combining signals of at least one wireless communication network and at least one digital network. A reference frequency generator is arranged in the master unit, the reference frequency generator being designed to clock a master modem for converting the signals of the at least one digital network. The reference frequency signal emitted by the reference frequency signal is restored via a reference frequency receiver and is used for closing a remote modem that is located there for demodulation.

  • Publication number: 20130071112
    Abstract: Certain aspects are directed to a configuration sub-system for telecommunication systems. The configuration sub-system can include a test signal generator, a power measurement device, at least one additional power measurement device, and a controller. The test signal generator can be integrated into components of a telecommunication system. The test signal generator can provide a test signal to a signal path of the telecommunication system. The power measurement device and the additional power measurement device can respectively be integrated into different components of the telecommunication system. The power measurement device and the additional power measurement device can respectively measure the power of the test signal at different measurement points in the signal path. The controller can normalize signals transmitted via the telecommunication system by adjusting a path gain for the signal path based on measurements from the power measurement device and the additional power measurement device.
