Nokia Siemens powers Indosat’s 3G mobile broadband promising spectrum efficiency

Telecom Lead Indonesia: Indosat has selected Nokia Siemens Networks for GSM and 3G mobile broadband infrastructure.

Using Nokia Siemens infrastructure, the Indonesian mobile service provider will offer mobile services in 900 Mhz in Central and East Java, Sumatra, and Kalimantan.

The Finnish mobile broadband solutions provider that clocked marginal growth in revenue in third quarter will support Indosat in deploying Indonesia’s first commercial network to deliver 3G services in the 900 MHz band.

The new 3G service became available in Bukit Tinggi and Padang in West Sumatra on October 6, with the remaining regions across Central & East Java, Kalimantan and Sumatra coming up soon. The operator is using its existing 900 MHz for 3G services as permitted by a recent cellular license.

As Nokia Siemens will modernize Indosat’s GSM and 3G networks, the company will become Indosat’s exclusive vendor for radio access network (RAN) modernization in Central and East Java, Kalimantan and Sumatra.

Nokia Siemens’ technology and services will enable Indosat to run GSM and 3G concurrently on the 900 MHz band. Indosat will benefit from scalability, enhanced capacity and software-defined configuration of the new generation of Nokia Siemens’ radio network controllers.

“With Indonesia’s first 3G 900 network in West Sumatra, our users can enjoy greater coverage, faster data speeds, as well as high quality voice and data services. For example, HSPA coverage in rural areas and indoor coverage in urban areas will be greatly improved,” said Hans C Moritz, director and chief technology officer at Indosat.

By implementing the Single RAN and Flexi Multiradio 10 Base Station, WCDMA and GSM services share a common platform which allows each pair of technologies to be delivered by a single radio module. By deploying Nokia Siemens Networks’ Liquid Radio GSM Software Suite, Indosat will enjoy high spectral efficiency of the spectrum frequency.

“The contract with Indosat to modernize its existing network and enable the first commercial 3G 900 network in the country marks an important milestone in our business,” said Dharmesh Malhotra, head of Indonesia at Nokia Siemens Networks. “It further strengthens our relationship with Indonesia’s premier operator. We remain committed to helping Indosat address the rapidly growing demand for high-speed data services.”

According to a recent report in, Spain’s telecom operator COTA has conducted TD-LTE pilot project thanks to Nokia Siemens Networks.
