Abstract

This disclosure provides methods and arrangements for ensuring proper and correct packet based synchronization in data communications systems and networks at distribution of synchronization packets from one Access Point (12)over a WIFI transport link (25)to another Access Point (14). The arrangement provides dynamic transmission rate adaption with different coding and modulation schemes. Said arrangement comprises an identifier (36 , 38) to identify each received synchronization packet, and a controller (32 , 34)is configured to set the transmission rate for said synchronization packet according to a predetermined synchronization packet transmission rule.
