Dialog Paves the Way for 5G with Successful Massive MIMO Trial

24 May 2017         Colombo


Sri Lanka’s premier connectivity provider, Dialog, continues to blaze a trail in the region’s technology transformation with South Asia’s first successful trial of next-generation, Massive MIMO (Multiple-Input Multiple-Output) Technology.

Massive MIMO Technology offers greater spectrum efficiency with up to six times more capacity from the same spectrum resource. In the race to 5G with unprecedented improvements in network throughput and capacity, MIMO is considered the most compelling technology with superior energy and spectral efficiency. Dialog recently concluded a trial MIMO deployment that delivered speeds up to 716Mbps over a single 20MHz LTE TDD carrier.

Massive MIMO uses a higher number of antennas to enhance capacity and transmit parallel data streams to users on the same frequency. By employing multiple antenna elements per user, Massive MIMO base stations could also carry out ‘beam-forming’, whereby the antenna beam could be focused towards individual users to enhance connectivity and reduce interference.

Dialog Axiata’s Group Chief Executive, Supun Weerasinghe, says: “The successful pilot of MIMO underscores Dialog’s unremitting commitment to stay abreast of nascent technologies to offer the very best in connectivity to all Sri Lankans. Dialog’s ability to deliver inventive and life-changing technology solutions have been empowered by a progressive regulatory environment and the support of our valued business partners, who have worked hand-in-hand to make Sri Lanka’s rapid ascent towards 5G an enriching experience to both enterprises and consumers alike.”
