Assessment of Open Ran: Difference between revisions

Greenfield Open RAN deployment refers to the installation and configuration of an entirely new network. That is, the operator is starting from scratch. On the other hand, a brownfield deployment is a scenario where the operator integrates Open RAN with existing networks. Unlike the greenfield operator which has only 4G and 5G networks, brownfield operators would have legacy 2G, 3G and sometimes 4G networks. This legacy networks need to be integrated with the Open RAN architecture in order to achieve the long term gains of the new network. Therefore, in contrast to the greenfield operator, the brownfield network provider is not immune to Open RAN integration challenges. The most prominent greenfield operators in the world are Rakuten and Dish.
