New solution for distribution network to deliver seamless communications service
SK Telecom successfully deploys 5G-PON, next generation technology for RAN Radio Access network
- The solution serves both wireless and wired connectivity such as LTE, 5G and broadband access, making it easy to deliver a broader coverage of 5G services
- It requires smaller devices and equipment installable in outdoor settings, delivering a higher level of satisfaction to the premises
Will continue to build stronger capabilities in advanced network technology necessary for 5G rollout
Seoul, Korea, November 17, 2017 ? SK Telecom (NYSE: SKM) today announced that it successfully deployed 5G-PON(Passive Optical Network), next generation technology for distribution networks, that can deliver both LTE and 5G communications services.
The mobile communications network is a collection of interconnected networks throughout the country. Distribution networks refer to networks connecting base stations with RRHs 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 solution will facilitate the process of delivering a broader coverage for the 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. The conventional device need to be installed inside the premises for power supply. 5G-PON solution, however, can be built in outdoor settings as it requires no power supply, delivering a higher level of satisfaction to the premises.
In addition, the solution can be constructed in a protected ring architecture. Therefore, even if line is disconnected, the communications services are delivered seamlessly using the other line.
SK Telecom will roll out 5G-PON service in 85 areas nationwide including Seoul, Busan, Daegu, Daejeon and Gwangju, and expand the deployment further ahead. It particularly expects that the quality of service will get improved in rural areas thanks to the easier deployment of 5G-PON.
The solution is the result of SK Telecom’s collaboration with local vendors, such as Solid, HFR, SunwaveTec and Coweaver, which have strong capabilities in optical communications technology. 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. “We will continue to develop our capabilities for advanced network technology and operation necessary for 5G rollout.”
