Delivering timing accuracy in 5G networks
How IEEE 1588 PTP has evolved to meet the stringent time synchronization requirements of 5G In mobile networks, time synchronization has always been important. Each new generation of mobile networks has driven the need for increased precision and accuracy in synchronization standards and solutions. Nevertheless, 5G is different. 5G time synchronization requirements are the most demanding seen to date and have elevated the importance of time synchronization and the need for more accurate solutions. It is 5G requirements to support Ultra-Reliable Low-Latency Communications (URLLC) services, which are driving the need for greater timing accuracy. The 5G vision of new revenue generating services like autonomous vehicle connectivity and eHealth services are simply not possible without highly accurate and reliable time synchronization. Even services like massive Industrial Internet of Things (IIoT) and other industrial automation services require reliable time synchronization. 5G is an entirely packet-based network from the core to the antenna. The challenge for 5G networks is how to provide ultra-reliable and highly accurate time synchronization over the 5G packet network. The answer is IEEE 1588 Precision Time Protocol (PTP).
