Samsung is an active member of the Open RAN community, participating in large-scale deployment tests, conferences and most recently, commercialising a new carrier-grade, fully-virtualised 5G RAN solution. The Korean tech conglomerate’s emphasis on developing a vendor agnostic ecosystem has been well-received as it leads several large-scale partnerships and deals with communications giants including Verizon and AT&T.

Mid 2020, Samsung won a $6.6 billion dollar deal to supply network equipment to American CSP, Verizon, a project lasting approximately 5 years and would equate to about 3.4 percent of Samsung’s 2019 group revenues. This opportunity is a heavy blow to Nokia, who have historically supplied Verizon with almost 50% of their RAN solutions. As US-China tensions rise, European vendors receive an upper hand in filling the gaps left by their Chinese counterparts, however, missed opportunities like these will continue to exacerbate the divide in the vendor community. Despite recent success, it comes at a surprise that Samsung has yet been called to support many other large-scale American network deployments including that of T-Mobile’s massive 5G network upgrade. This does not prove to be an issue, as the Korean conglomerate continues to support deployments elsewhere including Telus in Canada, KDDI in Japan and Spark in New Zealand.

On other news, Samsung has recently announced a successful collaboration with AT&T to demonstrate an open-interface approach to delivering 5G deployments. The solution that leverages on the enhanced Common Public Radio Interface (eCPRI) and Samsung’s network hardware paves the new possibilities CSP-vendor partnerships can achieve. As Samsung takes a collaborative approach in developing its open RAN technologies, it will be interesting to see how the industry, especially vendors, may adopt their strategies to capture a larger 5G market.
