Benefits of technology

This patent describes a method called spread sequencer that uses a specific type of device called a reference frequency generator (RF) to generate signals at different frequencies. These signals are then combined together by adding them together to make it easier to remove any unwanted signals without affecting the desired ones.

Problems solved by technology

The technical problem addressed in this patent is how to efficiently distribute and combine signals sent over various networks while maintaining their quality.

Embodiment Construction

[0043]FIG. 1 shows diagrammatically the common transmission of signals of two digital networks and of signals of three wireless communication networks between a master unit 2, 2′ and a remote init 3, 3′. The master unit 2, 2′ and the remote unit 3, 3′ together form a multiband transmission system 1 for distributing and combining signals of at least one wireless communication network and of at least one digital network. The downlink region is hereby labeled by 2, 3, while the uplink region is given by 2′ and 3′.

[0044]The master unit 2, 2′ hereby comprises signal lines a, b or a′, b′ for transmitting or exchanging signals within respectively one digital network. The digital data before transmission by means of a first master modem 5 and by means of a second master modem 6 are hereby modulated on a carrier frequency. Both master modems 5, 6 are hereby embodied for a multi QAM modulation. In the uplink direction the further master modems 5′ and 6′ are provided for the demodulation of the c

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.
