The introduction of 5G challenged many component manufacturers who serve the telecom industry.
Timing and Synchronization is certainly one of them. Implementing features such as beam steering and
millimeter wave communication called for much more accurate timing solutions. These solutions would
also have to be robust given the varying environmental condition where the small cells would be installed.
As the industry shifts towards a more complex Radio Access Network (RAN), it is expected to see more
of a cohesive and standardized approach to its implementation. The Open RAN architecture (O-RAN) is
on the forefront of this initiative.
Within O-RAN, the remote radio unit (RRU) serves as the access point to the network. A user will connect
to the RRU, the data will reach a front haul switch, and then proceed to an edge server or distributed
unit (DU). The DU will then pass information to the central unit. Synchronization between these stages is
critical for 4G, but even more critical for new 5G applications. This is accomplished using a synchronization
method governed by a Precision Clock Synchronization Protocol called IEEE 1588.

在O-RAN中,远程无线电单元(RRU)充当到网络的接入点。用户会选择贴片石英晶振,也会连接到RRU,数据将到达前端传输开关,然后继续到边缘服务器或分布式服务器单位(DU)。然后,DU将信息传递给中央单元。这些阶段之间的同步是对于4G来说至关重要,但对于新的5G应用来说更是如此。这是通过同步来完成的方法受称为IEEE 1588的精确时钟同步协议控制。
