How Timing Design And Management Synchronizes 5g Networks 5g Miclk. easily plugged into service routers to simultaneously distribute frequency and time, the patented miclk eliminates the need to install gps gnss antennas at every cell site while providing highly accurate timing distribution with full network coverage – even in underground and in building installations. In many cases, synchronization in a mobile network will benefit from the implementation of a combination of methods. as shown in figure 4, a fairly typical 5g mobile network can combine methods like gnss and oas at base station sites, time and frequency distribution via the transport network, and redundancy and holdover functions in the nodes.
Network Timing Synchronization For Mobile Networks 5g mobile radio requires “phase synchronization” (aka phase time) different to, and more complex than previous “frequency synchronization”. 5g networks have strict phase time requirements to work correctly. frequency sync nowadays typically uses synce enhanced synce not tdm. driven by need to optimize the use of the radio spectrum. 5g expands timing requirements network timing and synchronization across devices has always been required for operating mobile networks. timing is more critical than ever due to much stricter requirements mandated to operate 5g networks and new use cases supported. new 5g deployments require higher performance and cost effective timing. Timing and synchronization standards for mobile networks prevent messages from interfering with one another and enable smooth cell to cell transfers. the increased stringency of timing and. Figure 3 illustrates the synchronization requirements in the end to end transport network. ericsson proposes timing budgets allow for 1.1 µs time of day difference from the core of the network to the access edge, and about 400 ns from the access edge to the radio. this gives a total budget of 1.5 µs absolute time of day difference between.

The importance of synchronization in 5g networks. in previous generations of mobile networks, synchronization was essential for facilitating call handovers between base stations as users moved from one cell to another. in 5g, synchronization plays an even more significant role by enabling the high capacity and low latency that users expect. The g.8275.1 profile is designed to provide the most accurate time synchronization solution within the timing budget constraints of 1.5μs from the primary reference time clock (prtc) to the antenna outlined in the itu t standard g.8271.1, “network limits for time synchronization in packet networks with full timing support from the network”.
