1- D-RAN stands for \u201cDistributed RAN\u201d<\/strong><\/em><\/p>\n

D-RAN is a classical setup where RRU (Remote Radio Unit) and BBU (BaseBand Unit) are co-located at every cell site. They run proprietary applications on specialized hardware. Each radio site with all of its functions are in a single location and connected back to the core network through backhaul.<\/p>\n

2- C-RAN (Also CRAN) stands for Centralized RAN or Cloud RAN<\/strong><\/em>.<\/p>\n

In C-RAN the BBUs from several sites are grouped into a pool\u00a0 and located in one location. This leads to more efficient use of computing resources. but what is important to understand is that we still need\u00a0 software and hardware to be coming from a single vendor.<\/p>\n

3- vRAN called also\u00a0 Virtualized Ran or Centralized Ran<\/strong><\/p>\n

vRAN decouples the software from hardware by virtualizing Network Functions. It uses virtual machines (VNF approach) or containers (CNF approach) to deploy CU and DU on top of COTS servers.<\/p>\n

vRAN and C-RAN are very similar. Only difference is that C-RAN uses proprietary hardware while vRAN deploys on top of COTS servers that you can find typically into a Datacenter.<\/p>\n

4- Then finally OpenRAN<\/strong><\/em><\/p>\n

The O-RAN alliance made a great job creating a specification for open fronthaul, mid-haul and backhaul interfaces.
\nThis means that finally you can mix and match different vendors, and use different approaches without vendor lock-in.<\/p>\n","protected":false},"excerpt":{"rendered":"
