Open RAN?
Whats the difference between RAN and Open RAN? --2A02:908:898:9780:EE57:1C33:B08F:53EC (talk) 02:54, 27 April 2023 (UTC)


 * Open RAN is an architecture of a 5G RAN that separates the traditional base station into different components, specified by the O-RAN Alliance. Here is some reading to understand how the 5G gNB is split up into the RU, DU, and CU. That article doesn't go into a ton of detail on the RIC, which is used to load balance the rest of the external network. Here is an article about the different kinds and functions of the RIC.
 * The main benefit of an Open RAN is that each gNB component can be sourced from different vendors because the interfaces between them are publicly specified and standardized. In the past, the whole gNB had to be sourced from a single vendor with proprietary interfaces. Open RAN disaggregates the gNB and allows for more competition in the telecommunications market.
 * The downside of an Open RAN is that the multitude of vendors' network devices may not work completely seamlessly with each other; while all Open RAN devices must be compatible according to the O-RAN specifications, some manufacturers can add features that only work between their devices and not others. There are also more opportunities for cybersecurity flaws due to the interoperability of various devices and the connection interfaces between them. Open RAN could benefit from a separate but related article, as most governments and telecommunications companies have embraced it. 64.157.241.252 (talk) 21:21, 28 July 2023 (UTC)
