New Telkomsel, Indonesia, expands coverage and capacity with a cost and energy efficient solution.

Telkomsel is the market leader in Indonesia with a 54 percent share in the country's telecommunications market. In order to maintain and build on this position, Telkomsel needed to continue its successful strategy of expanding coverage ahead of the competition.

Ericsson supplies a third of the operator's network and, with a growing reputation in energy efficient network expansion projects, was the perfect partner to support its growth. By continuously expanding its coverage, Telkomsel increases subscriber numbers and ensures its market position, but the remote diesel powered sites traditionally required to do this, take a lot of maintenance and this can substantially increase OPEX. Ericsson offered a 100 percent solar-driven site which was easy to install and kept maintenance costs to a minimum. Per-Henry Olsson, Vice President, Telkomsel Account, Ericsson Indonesia, explains how the project helps Telkomsel to realize its vision: "The solar site is an energy efficient solution, which guarantees low OPEX going forward, helping to maintain Telkomsel's strong position in the market."

The entire site was delivered and installed by Ericsson, including the radio base station, MINI-LINK™ and the power solution. The main remote base station, the RBS 2111, is divided into two separate units. The main unit connects to network transmission at ground level and the remote radio unit sits at the top of the mast and contains the radio hardware. The distributed architecture reduces the total site costs and ensures fast and easy rollout. The RBS 2111 makes it possible to produce a total site solution which is power efficient enough to use with solar equipment and 100 percent solar energy guarantees Telkomsel a virtually maintenance free site. This is the first time that a combined solution of this kind has been implemented and the trial period has shown it to be incredibly efficient, using 60 percent less power compared with ordinary macro base stations. This guarantees cost efficiency as well as being good news for the environment.

The deployment has been a success and it is anticipated that it could lower OPEX by up to 40 percent. Bona LP Parapat, Vice President, Radio, Network, Engineering and Implementation, Java and Bali, Telkomsel, Indonesia, explains some of the key benefits: "We have been concentrating on providing coverage for rural areas for some time. This solution will enable us to continue this policy in regions outside the power grid, while keeping energy consumption to a minimum and OPEX at a manageable level."
