  • Method of frequency synchronization in a wireless communications system and configuration for implementing the method
    Patent number: 6928286
    Abstract: The wireless communications system synchronizes the current frequency and permits communication under the DECT protocol between a mobile unit and a fixed base station with rapid and frequent changes in frequency, as defined for example in the ADCT protocol. For this purpose a key is derived from the identification code transmitted by the base station. Lists containing random or pseudo-random frequency sequences are specified, and one of the lists is selected depending on the key transmitted, and the corresponding frequencies are used for the frequency change.
