Open vs. Proprietary 5G Fronthaul Interface: SK Telecom Case

 

SK Telecom, having built and operated the world’s best LTE nationwide network, is now paving a way to launch its commercial 5G network in March 2019.

 

Most mobile operators in the world are under pressure of high costs of building 5G radio access network (RAN) because 5G, using mmWave frequencies, requires more densely installed base stations, which apparently means intensive financial investment, compared to 4G LTE.

 

SK Telecom announced on December 15 last year that its newly developed “open 5G fronthaul interface specification” was adopted as a Korean national standard by the Telecommunications Technology Association (TTA). This report covers the "5G RAN architecture and Fronthaul" strategies that are being shaped by SK Telecom. 
 

This report will discuss the two key challenges in 4G C-RAN (i.e. fronthaul capacity and vendor-proprietary interface) along with the solutions proposed so far in the industry.
 
It will also introduce the 5G RAN-architecture and open interfaces proposed in the 5G open fronthaul interface standard by SK Telecom.
