Some Telcos don't liek to pay for the R&D of Telecom Gear Makers. With the advancement of innovation in Wireless Radio & Computing, together backed by Open Source developers, Telecom players want to deploy ORAN [Open Radio Access Network] Vs the 5G Standard Equipment Developed by companies such as Samsung / Ericsson / Nokia etc
The primary difference between ORAN and traditional gear-makers is that the latter follow the 3GPP standards. For 5G, it is the 3GPP Release 15. The standards are a set of stipulations about different aspects of the network's delivery to customers - for instance, speed, bandwidth requirement and other parameters of service quality. Each equipment maker will attempt to differentiate itself by choosing to improve over the 3GPP standards. In ORAN, the 3GPP standards may either not be followed or perhaps only partially followed. This creates the problem of non-standardisation.
Telecom Networks globally will co-exist with 4G and 5G, thus interoperability between the technologies will also become essential in the years to come. However, the 5G ORAN is recent and therefore, its backward compatibility with standardised 4G networks cannot be taken for granted.
Ericsson, Nokia and Samsung have deep experience in setting up and managing large networks with thousands of towers, which the ORAN-based solutions will not be able to match for some time.
ORAN will be a cheaper solution, because the hardware is already a commodity and the software is now increasingly being written by many developers. While 5G Gears sold Commercial Off the Shelf by companies such as Nokia, Ericsson, Samsung etc will come at a cost.
