Telkomsel selects Infinet solution to improve access to remote areas

7 Sep 2021

Telkomsel (Telekomunikasi Selular), the 65%-owned mobile subsidiary of Telkom Indonesia, has picked Infinet Wireless – one of the largest privately owned broadband wireless access (BWA) development and manufacturing companies in the world – to help improve connectivity in ‘challenging terrain’ across the archipelago. In a press release, the vendor noted that with Telkomsel requiring both additional bandwidth and a cost-effective solution to support its IP microwave technology, VSAT or optical cable-enabled network of base stations, it is providing orthogonal frequency-division multiplexing (OFDM) radio equipment, resulting in the delivery of a radio link of 180km ‘to provide connectivity despite different obstacles, such as obstructive hills in the area, the ocean and the islands’.

The report goes on to note that Infinet’s technological partner, KISEL Group, a telecommunications services infrastructure provider, supplied the equipment, designed deployment of the links, and carried out support for the deployment of OFDM backhaul via local unit Wiralom Sistem. KISEL Group planned to rely on a more cost-efficient solution by taking advantage of the unlicensed 5GHz frequency band — a steady, carrier-class product, providing high-throughput performance and capable of working in nearLOS/NonLOS conditions. Wirakom Sistem reportedly contributed to the successful design of a network that delivered the aggregated 108Mbps service over a ‘record-breaking’ 180km distance.

Telkomsel General Manager Transport, Passive & Power Planning Division, Teddy Indira Permana, said: ‘We were impressed with Infinet OFDM as one of our rural transmission solutions, especially the new Quanta range, which covers nLOS terrestrial transmission in hilly terrain with good quality and at an affordable price. Thanks also to the KISEL & Wirakom team, which has been supporting us as an intermediary company. It has delivered the service in several projects in Telkomsel, especially related to reducing satellite cost and special area development projects. Infinet has made the impossible propagation possible, delivering sufficient capacity and good quality.’
