Indosat picks NSN for 3G network upgrade

11 Jun 2010

Indonesian mobile operator Indosat has selected Nokia Siemens Networks (NSN) to enhance and upgrade its 3G networks and help reduce its carbon footprint. The network enhancement will allow the cellco to offer subscribers data transmission speeds of up to 42Mbps, it said. Harry Sasongko, president director & CEO of Indosat, is quoted as saying: ‘We are proud to launch the fastest internet access service, providing Dual-carrier High Speed Packet Access Plus (DC-HSPA+) speeds of up to 42Mbps per user. This makes us the first Asian operator and the second in the world to do so … Besides fast downloads for users, Indosat also creating a ‘green telco’ through network modernisation that reduces power consumption, increases efficiency, and contributes to an eco-friendly environment.’

Under the upgrade, NSN is understood to have deployed its so-called ‘SGSN’ solution to ensure effective traffic offload. The equipment manufacturer says the SGSN serves both 2G and 3G/HSPA users and that any or all 3G/HSPA users can also be connected to the internet via an HSPA-enabled base station. The platform uses capacity dynamically to serve any given traffic mix without having to dedicate capacity or hardware to 2G or 3G. In addition to this, the vendor has implemented Flexi Multiradio Base Station to facilitate a rapid migration to Long Term Evolution (LTE) technology. Indosat’s network in Surabaya went live with the new technology at the end of May, and its network in Medan is scheduled to go live at the end of this month.
