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.
