SK Telecom claims it has developed and commercialised a technology that runs 2G and 3G backhaul over an LTE network for the first time.
The company said its ‘2G/3G over LTE’ uses an LTE network for backhaul instead of a fixed-line infrastructure, which can improve the stability of 2G/3G mobile networks.
Since mobile operators generally support their mobile networks with structural redundancy to be prepared for emergencies, the technology is designed to replace a redundant fibre-optic network, which can significantly improve operating efficiency.
This means that when the fixed-line 2G/3G infrastructure is damaged, the operator can still provide its customers with a similar quality of mobile service by using its LTE network, the company said.
2G/3G over LTE also is being promoted as an essential technology for mobile operators in developing markets that lack fixed-line infrastructure.
SK Telecom said it developed the technology after resolving the challenge of connecting a 2G/3G voice network to its data-only LTE network.
It plans to use the technology in 600 base stations by 2016.
