Abstract: An information transmission system is formed by a first transmission assembly and second transmission assembly. A telecommunications device is provided to have access to these two assemblies of the time-division type to produce information pulses at times that differ from each other. Thus, double traffic is obtained simultaneously.

Abstract: Antenna-gain diversity is obtained in the following manner. A first and a second antenna element (A1,A2) are electro-magnetically coupled. A switchable antenna-coupler (SAC) is switchable between: a first antenna-coupling state (S1) in which the first and the second antenna element (A1,A2) are electrically coupled to an antenna-signal node (N); and a second antenna-coupling state (S2) in which the first antenna element (A1) is electrically coupled to the antenna-signal node (N) and the second antenna element (A2) is electrically coupled to signal ground (GND). This type of antenna-gain diversity is particularly suitable for use in an application which needs to be relatively small in size or relatively inexpensive, or both, such as a cordless telephone, for example.

Abstract: This information transmission system is formed by a first transmission assembly (1) and a second transmission assembly (2). A telecommunications device (5) is provided to have access to these two assemblies (1) and (2) of the time-division type to produce information pulses at times that differ from each other. Thus one simultaneously obtains double traffic.
