Nokia Siemens Networks has been selected by Indonesia’s leading mobile operator to modernise its mobile broadband network.

The vendor is to provide the infrastructure that will allow Indosat to run GSM and 3G services concurrently on the 900 MHz spectrum band.

The operator launched the 3G service earlier this month.

NSN is providing single radio access network (RAN) technology, which will allow the operator to deliver WCDMA and GSM services through a single radio module.

Hans C Moritz, Indosat director and CTO, said: “With Indonesia’s first 3G 900 [MHz] network in West Sumatra, our users can enjoy greater coverage, faster data speeds, as well as high quality voice and data services.”

Indosat hosts more than 50 million subscribers throughout Indonesia.

Dharmesh Malhotra, NSN’s head of Indonesia, said that the contract marks “an important milestone” in the company’s business.

“This deal 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,” he said.

Earlier this month, NSN revealed that sales in the Asia-Pacific region rose 29 percent during Q3.
