Digital enhanced cordless telecommunication systems synchronization
First Claim
1. A DECT system comprising a base station and at least one handset therefore, said system connected to a data communication network system including a telecommunications service and characterised in that the connection is via a broadcast data receiver connected to the data communication network system for the reception of data therefrom and at the broadcast location or head end of the cable network system, a timing reference is generated and transmitted via the data communication network system and received and referred to by the DECT system base station via the broadcast data receiver.

Abstract
The invention relates to the provision of a means for preventing interference and the occurrence of “sliding collisions” when two or more DECT communication systems are used in relatively close proximity The invention provides for the connection of the DECT systems to a data communication network along which a timing reference signal is carried such that the DECT systems connected to the network are synchronised. In one embodiment further steps can be taken to adapt the timing reference signal to take into account changes in the distance from the respective DECT systems to the data communication system head end at which the timing reference is generated.
