SK Telecom announced today that it will sign an MoU on global expansion of 5G-PON at the MWC 2018 in Barcelona, Spain with global telecommunications equipment companies such as Cisco Systems and Nokia. 5G-PON is one of 5G network’s core technologies.

5G-PON (5G-Passive Optical Network) is a next-generation technology for distribution networks that connects Radio Unit (RU) such as antennas and heavy machineries installed at the premises with Baseband Unit (BBU).

In comparison to the 4G-LTE era, base stations should be set up more densely in the new 5G era as the volume of transmitted data increases exponentially. With that, the importance of network that transmits wireless data signals received at the point of network users to Baseband Unit grows. 

5G-PON technology can improve the quality of mobile communications in remote rural areas. Whereas traditional wired network needs to be installed inside a building for power supply, 5G-PON can be operated without a power switch, allowing it to be more conveniently deployed outdoors.

Unlike Ultra-High-Speed Internet, 3G, and LTE which requires an additional network for different types of network, 5G-PON can facilitate the process of data delivery by simply installing base stations and antennas without the need of additional networks. This means the solution can be more conveniently and quickly implemented nation-wide. 5G-PON also uses about 20% less time for the 5G deployment compared to the 4G-LTE.

In 2016, SK Telecom sold RingMUX, its fronthaul solution for LTE network, to Verizon and in September 2017, it signed a contract with India’s Bharti Airtel to export its AI network solution, by forming an ICT alliance with the country’s small yet strong companies.

“SK Telecom is focused on securing innovative network technology to provide our customers with the safest and most stable 5G communications,” said Kang Jong-ryeol, Executive Vice President of ICT Infra Center, SK Telecom. “By partnering with the country’s small yet strong companies, we will roll-out the world’s first 5G network.”
