  • Patent number: 11128371
    Abstract: A DECT system and a method for communicating between a DECT fixed point and multiple DECT portable points. The method may include step (a) of communicating between a master communication processor of the DECT fixed point and one or more DECT portable points during master communication slots. The method may also include step (b) of communicating between a slave communication processor of the DECT fixed point and at least one of the DECT portable points during slave communication slots. Step (a) and step (b) are executed according to an allocation of master communication slots and slave communication slots, wherein the allocation facilitates concurrent slave communication processor communications and master communication processor communications.

  • Patent number: 9565632
    Abstract: A method that includes operating a base station at a first operational mode thereby preventing the base station from a periodically transmitting a beacon; detecting, by the base station, a transmission from a first wireless communication device; determining, by the base station and in response to the transmission from the first wireless communication device, whether to continue operating in the no emission mode or to enter a emission mode during which the base station is allowed to transmit the beacon; and entering the second operational mode, if it is determined to enter the second operational mode, and sending the beacon to the first wireless communication device.

  • Patent number: 7948928
    Abstract: Cordless telephones according to the DECT standard are constantly transmitting a so-called dummy barrier at a certain power level, repetition interval and transmit frequency to apply corrections to the synchronization counters in the portable parts for synchronization to the fixed part. According to the present invention, once timing of the portable part is synchronized to the fixed part, a wired connection is used for applying these small synchronization corrections with respect to the synchronization between the portable part and the fixed part of the DECT telephone system. Advantageously, an emission of electromagnetic energy is thereby reduced significantly.

  • Publication number: 20090092119
    Abstract: The present invention relates to a transceiver device and a method of controlling a time-division multiplex frame structure with time slots in active mode in which a bearer is established, and time slots in an idle mode in which no bearer is established. Adjacent first and second time slots are set in a scanning mode when the transceiver device is listening for bearer set-up attempts, and the first time slot is switched from the scanning mode to the idle mode if a bearer has been established in the adjacent second time slot and the adjacent second time slot is set into the active mode. Thereby, a non-blind-slot scanning mode is provided which enables maximum number of active full and double slots in systems with blind slot radio.

  • Publication number: 20080159355
    Abstract: Devices (1,2) for use in frequency hopping systems (3) for frequency hopping through frequencies of a sequence of frequencies get a better overall performance by introducing selectors (4) for selecting the sequence from a number of sequences, which number of sequences comprises a first sequence and a second sequence, which first sequence is longer than the second sequence. Generators (7) generate the first and second sequences. Monitors (5) monitor channels in use and controllers (6) control the selectors (4) for, in a first mode, selecting the first sequence and for, in a second mode, selecting the second sequence in dependence of a monitoring result. Modifiers (8) modify the second sequence. The second sequence may form a subset of the first sequence. This all results in an increased overall quality and a reduced power consumption.

  • Publication number: 20060245387
    Abstract: Cordless telephones according to the DECT standard are constantly transmitting a so-called dummy barrier at a certain power level, repetition interval and transmit frequency to apply corrections to the synchronisation counters in the portable parts for synchronisation to the fixed part. According to the present invention, once timing of the portable part is synchronised to the fixed part, a wired connection is used for applying these small synchronisation corrections with respect to the synchronisation between the portable part and the fixed part of the DECT telephone system. Advantageously, an emission of electromagnetic energy is thereby reduced significantly.
