Mobile phone terminal, having a transmitter stage, a receiver stage and an antenna switch-over and adapter stage which each have an arrangement of passive structural elements, which arrangement is assigned a multiplicity of electrostatic-mechanical microswitches or microrelays and which can be programmed by actuating a predetermined configuration of the microswitches or microrelays in, in each case, at least one functional parameter, in particular the frequency characteristic, and a programmable control unit.

Mobile phone terminal with programmable microelements

A programmable mobile phone terminal includes a transmitter stage, a receiver stage, a switch-over and adapter stage having an arrangement of passive structural elements connected to a plurality of microswitches or microrelays programmed by a predetermined configuration in at least one functional parameter, and a control unit associated with the transmitter stage and the receiver stage, for setting predetermined values of the functional parameter.

Programmable mobile radiotelephone terminal

In a method for indoor operation of a wireless telecommunication device that comprises at least one base station and at least one mobile part, the momentary reception power is measured in the receiver of the mobile part and the reception power value is communicated to the base station for the control of the transmission power. The ratio of reception power to noise power is determined at predetermined time intervals in the receiver of the mobile part. The respectively obtained ratio value is compared to a rated value and, dependent on the result, one signalling bit per data frame is transmitted from the mobile part to the base station. A calculation of the current or updated transmission power with adaptive incrementation control is then undertaken in the base station. The calculation of a current transmission power value thereby occurs on the basis of the previous transmission power value plus a product of a correction value determining the incrementation and a default value determined from the signalling bit.

Method for indoor operation of a wireless telecommunication device

For the expansion of a cordless telecommunications system, in particular a DECT cordless telecommunications system, with respect to great transmission ranges in cordless telecommunications there is provided in a cordless telecommunications system (PIZSL-TKS) a relay station (RS) which is assigned at least one cordless mobile station (PIZ-MS). In the case of cordless telecommunications, the relay station (RS) replaces a cordless base station (PIZ-BS) and, in the case of the expanded cordless telecommunications, it is designed as a cordless mobile station (MIZ-MS, MAZ-MS, HYZ-MS).

Universal mobile telecommunications system

Method and system for improving the degree of utilization of telecommunication channels in locally concentrated asynchronous wireless telecommunication systems wherein, in each telecommunication system, for a first telecommunication connection to be set up according to a hybrid multiple access method containing the FDMA principle, including a possibly provided &ldquo;dummy bearer&rdquo; telecommunication connection, a free, not-yet-occupied FDMA frequency is occupied with priority, and each further telecommunication connection following the first telecommunication connection, including a handover telecommunication connection, is set up with priority on the same FDMA frequency.

Method and system for improving the degree utilization of telecommunications channels in locally concentrated, asynchronous wireless telecommunications systems

The radio area to be covered by the stationary radio transmission/reception device, for example of the base station of a cordless telephone, is illuminated by two or more directional antennas (,) respectively covering a radio sub-area thereof, whereby that respective directional antenna in whose radio sub-area the mobile radio transmission/reception means, i.e., for example, the mobile part of the cordless telephone, is located is activated (antenna diversity). The method and apparatus can be advantageously utilized in cordless telephones.

Method for signal transmission in a communication system between a mobile radio transmission/reception device and a stationary radio transmission/reception device

A process for receiving data in which the channel pulse responses are estimated, whereby a time interval between adjustments of a receiver to current channel pulse responses is varied and is adjusted to a change in transmission properties of transmission channels.
