Network synchronization in the time domain (part 2)

March 5, 2021 | by Manuel Mielke

Network operators have to make sure that synchronizing their networks will not produce any interference. Synchronization can affect several levels, these include synchronization on a relative time base, which was part of the blog post part 1 and extend to synchronization on an absolute time raster. Why? You can read all about it in part 2 of our blog post.

Network synchronization in the time domain (part 1)

January 14, 2021 | by Manuel Mielke

Network synchronization requirements are as old as digital cellular mobile networks. As soon as cells have a neighbor relationship, network synchronization is mandatory in both the frequency and time domain. How does 5G NR with its extremely flexible specifications affect these synchronization requirements, and how can they be measured?
