"I've been working with different transmission systems since the early 1980s but the focus on synchronisation issues has always been lacking. I attended the International Synchronisation MasterClass with three colleagues and found it very rewarding. After the course we started measurement of our mobile network and quite soon found the cause of problems for poor handover and missed calls in the network. We subsequently attended an internal synchronisation course delivered by another company. I have to say that the Chronos International Synchronisation Course is the one to choose."
