3 Indonesia has deployed Nokia’s 3G-4G dynamic spectrum sharing (DSS) technology in its live mobile network infrastructure to help the telecom operator dynamically extend its 4G bandwidth when the demand for 3G subsides.
The operator has concluded a trial of Nokia’s DSS software upgrade in Makassar, the capital city of Sulawesi, prior to a nationwide deployment. The trial extended 1.8 MHz of 4G bandwidth resulting in delivering 18 percent more spectrum for 4G customers without compromising 3G services.
Nokia said its DSS technology allows 3 Indonesia to extend 4G spectrum by reducing 3G spectrum in a dynamic fashion. DSS is based on the actual usage demands of both 3G and 4G customers, Andrew Cope, vice president of Mobile Networks in Asia Pacific & Japan at Nokia, said.
3 Indonesia engineers have extended 4G spectrum automatically without the manual intervention in order to manage the spectrum resource efficiently to support customer demand.
“Growing our subscriber base with limited spectrum is one of our major challenges but Nokia’s dynamic spectrum sharing technology gives us more network capacity for the seamless transition from 3G to 4G,” Desmond Cheung, CTO of 3 Indonesia, said in a statement.
