Indosat, NSN carry out 1800MHz LTE trial

21 Oct 2011

Indonesian telecoms operator Indosat and Nokia Siemens Networks (NSN) have conducted a field trial of Long Term Evolution (LTE) technology in the 1800MHz band. The trial, which took place in Surabaya and Denpasar in Bali, was based on frequency division duplex (FDD-LTE) technology and showcases the operator’s readiness to reuse existing spectrum for future 4G deployment. ‘LTE brings a new generation of communications to Indonesia,’ commented Hans C. Moritz, director and CTO of Indosat, adding: ‘Nokia Siemens Networks was an obvious choice for the trial due to its large installed base and ability to deliver LTE in the 1800MHz frequency band. The company’s technology leadership and excellent support services can help us re-use our existing 1800MHz band, currently used for 2G services, for future LTE services.’ NSN provided its commercial, end-to-end LTE solution for the field trial, including a radio network based on the Flexi Multiradio Base Station and Evolved Packed Core, comprising Flexi NS (Network Server) and Flexi NG (Network Gateway). It also supplied its Home Subscriber Server (HSS) to manage subscriber-related information and provide user authentication and authorisation. The vendor also provided network installation, commissioning and integration services.
