5G wireless communication

There is a significant trend in the RAN (Radio Access Network) market going from traditional vertically integrated RAN equipment towards a more open vRAN (virtualized RAN) and ORAN (Open RAN).  The vRAN/ORAN efforts bring in some new usage models and technologies that did not exist in traditional RAN, e.g.  open standards based definitions of RU, DU and CU, Containerized deployments for DU and CU, Kubernetes based orchestration, Cloud, etc The objective of this article is to give a brief into the basics of vRAN for people who are new to this domain. Although participants in 5G projects acquire knowledge about cellular communication from different sources many questions still remain This article attempts to answer frequently asked questions at deep level 4G versus 5G The RAN (4G) is the final link between the network and the phone. It includes the antennae we see on towers and on top of buildings connected to Basestation Units (BU).   When we make a call or connect ...
