System for tetra synchronisation with an adjacent zone

机译:与相邻区域进行四同步的系统

摘要

The invention relates to a system for the synchronisation of TETRA base stations using the reception of the base station occupying the adjacent zone, such that said synchronisation fulfils the type 1 and 2 handover functionality defined in the TETRA standard. For said purpose, the base station includes an ISYNC-type module comprising a receptor which is tuned to the frequency of the adjacent zone. According to the invention, a sufficient signal level for the aforementioned receptor is achieved using directional antennae which are directed towards the adjacent master zone. The ISYNC module generates synchronism signals in order to render same compatible with other synchronisation systems and, in addition, provides the reference for all of the base stations both in terms of time and frequency.
