SK Telecom plans to apply the technology to 600 base stations by 2016.
The telecom innovation enhances the stability of 2G / 3G networks by utilizing LTE network as backhaul instead of fixed-line 2G / 3G infrastructure. Even when the fixed-line 2G / 3G infrastructure is damaged, the company will still be able to provide its 2G / 3G customers with a similar quality of mobile service by using its LTE network.
LTE network can replace one of the two fiber-optic transmission networks in the redundancy network structure, thus enhancing the operator’s network building and operating efficiency. Korean mobile carriers usually build a mobile network with structural redundancy to prepare against emergencies to provide quality service at all times.
The technology can be used by mobile carriers worldwide who lack fixed-line infrastructure.
The company developed the technology after resolving the challenge of connecting 2G / 3G voice network to its data-only LTE network. 2G/3G over LTE is notable because mobile operators can replace fixed-line infrastructure of previous generations of mobile communication systems with next-generation wireless networks.
Choi Seung-won, senior vice president and head of Network Engineering Office, said: “With 2G/3G over LTE, SK Telecom’s 2G and 3G customers will be able to experience a stable and seamless service.”
