SK Telecom announced that it is deploying 5G-PON, a passive optical network technology it has developed for distribution networks – that is, the networks connecting base stations with remote units and antennas – for LTE and 5G services.

Unlike the conventional distribution networks, where different networks are required for 3G, LTE and broadband access, 5G-PON delivers multiple communications services using a single network.

SK Telecom said the solution will facilitate the process of delivering broader coverage for its 5G rollout by simply installing base stations and antennas without additional networks.

Also, it requires smaller devices and equipment than the existing distribution technology and operates without additional power supply. Consequently, while conventional devices need to be installed inside the premises to access power, 5G-PON can be installed outdoors as well as indoors.

SK Telecom says it will initially roll out 5G-PON in 85 areas nationwide including Seoul, Busan, Daegu, Daejeon and Gwangju.

The solution was developed by SK Telecom in collaboration with local vendors Solid, HFR, SunwaveTec and Coweaver. SK Telecom said it will propose the solution to the 5G network standards group of the ITU-T.
