If you look at the TIP (#OpenRAN) and O-RAN Alliance (#ORAN), the organizations driving the Open RAN vision and mission, you will notice many new small RAN players are joining one or both of them. In addition, you hear about other Open RAN consortiums that again include small innovative vendors that may not be very well known. This opinion piece looks at what is driving these companies to invest in Open RAN and what can they expect as return in future.
