Indonesian operator trials 1800MHz LTE
Indosat, Indonesia’s leading operator, and Nokia Siemens Networks have successfully conducted the country’s first Long Term Evolution (LTE) field trial in the 1800MHz band. The trial is based on FDD-LTE (frequency division duplex) technology and showcases Indosat’s network readiness to re-farm the existing 1800MHz frequency band. The trial took place in Surabaya and Bali in the presence of government representatives and regulatory authorities. During the trial, the companies showcased innovative applications such as e-doctor and e-education in the cities of Surabaya and Denpasar, which enabled a patient to remotely consult a doctor, and a lecturer to teach students, through video conferencing. In addition, 3D video streaming and CCTV camera surveillance were demonstrated. Nokia Siemens Networks provided its commercial, end-to-end, LTE solution for the field trial. This included 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 provided its Home Subscriber Server (HSS) to manage subscriber-related information and provide user authentication and authorization. Nokia Siemens Networks also provided network installation, commissioning and integration services.
