Users of 5G services say the first implementation of the next-generation network technology in South Korea has fallen short of expectations.

Starting last April with simultaneous rollouts by carriers KT, SK Telecom, and LG Uplus, nearly half of South Korea's population could access 5G services with a network-enabled device.

Strategy Analytics' Woody Oh said the lack of a killer app is one reason adoption has been soft.

5G's most obvious current benefit is the ability to rapidly transfer large data volumes, like faster movie downloads and seamless streaming of high-resolution content.

However, telecom experts said smartphone users get few benefits with 5G, with maintaining connections especially challenging.

Experts expect the technology's chief impact will be felt with driverless cars or smart cities.
