Nokia has announced that it has deployed its 3G/4G dynamic spectrum sharing (DSS) technology in Hutchison 3 Indonesia’s live network to help the cellco dynamically extend its 4G bandwidth when the demand for 3G subsides. In a press release, the vendor confirmed that Hutchison 3 Indonesia – which operates under the banner Tri – has successfully completed a trial of Nokia’s DSS software upgrade in Makassar, Sulawesi’s provincial capital, prior to a nationwide deployment. The trial reportedly extended 1.8MHz of 4G bandwidth resulting in an 18% increase in spectrum availability for its 4G customers, without compromising its existing 3G services.
Nokia says that its DSS technology performs automatically according to actual usage demands of both 3G and 4G customers, enabling 3 Indonesia to manage the spectrum resource efficiently to support customer needs. ‘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. We are very happy to work with Nokia to bring in this new technology to Indonesia so as to increase the network capacity and data speed to meet the ever increasing data demands,’ said 3 Indonesia CTO Desmond Cheung.
3 Indonesia’s 4G LTE network is currently live in over 33,000 towns/villages in Sumatra, Kalimantan, Sulawesi, Java, Bali and Lombok, supported by 16,000km of fibre-optic cables.
