We report on the upgrade of a fiber optic network for time and frequency transfer between PTB in Braunschweig and the test center of Deutsche Telekom in Bremen, Germany. The network provides 10 MHz and 1 PPS signals at remote locations intended for the supervision of the mobile telecommunication network of Deutsche Telekom. Here we present the results of the time transfer calibration of the link.
The operation of a mobile telecom network relies directly on the synchronization of thousands of base stations that must be robust and operate reliably 24 hours a day. Nowadays networks using advanced Long Time Evolution (LTE) standard need not only frequency syntonization, but also time synchronization that should ideally be traceable to UTC. In this work we present first results of providing UTC(PTB)...
