SK Telecom said it will deploy 5G-PON (Passive Optical Network) technology in 85 areas in Korea for enhancing distribution networks to deliver both LTE and 5G services.
Distribution networks refer to networks connecting base stations with remote units and antennas installed at the premises.
Unlike the conventional distribution networks, where different types of network are required for 3G, LTE and broadband access, 5G-PON solution delivers multiple communications services using a single network.
The 5G-PON solution will facilitate the process of delivering a broader coverage for the 5G rollout by installing base stations and antennas without additional networks.
SK Telecom said the 5G-PON solution requires smaller devices and equipment than the existing distribution technology and operates without additional power supply. The conventional devices need to be installed inside the premises for power supply. 5G-PON solution can be built in outdoor settings as it requires no power supply, delivering a higher level of satisfaction to the premises.
The solution can be constructed in a protected-ring architecture. The communications services are delivered seamlessly using the other line even if a line is disconnected.
SK Telecom will roll out 5G-PON service in 85 areas including Seoul, Busan, Daegu, Daejeon and Gwangju. It expects that the quality of service will get improved in rural areas thanks to the easier deployment of 5G-PON.
SK Telecom has tied up with local vendors such as Solid, HFR, SunwaveTec and Coweaver to develop the 5G-PON solution. SK Telecom will propose the solution to the 5G network standards of the ITU-T.
“With 5G-PON built on our own specifications, we secured opportunities to improve the quality of service and lay the foundation for a successful rollout of 5G,” said Choi Seung-won, head of Infrastructure Strategy Division, SK Telecom.
