Sri Lankan operators trial 4.5G technology, achieve 1Gbps speeds

20 Jun 2016

Sri Lankan operators Dialog Axiata and Mobitel have each announced successful trials of 4.5G technology, demonstrating download speeds in excess of 1Gbps. In a press release, Dialog confirmed that its test was carried out over its LTE infrastructure in partnership with Huawei, with the throughput delivered via the LTE Radio (Air) Interface. Dialog notes that following the test, it has joined 20 countries where 4.5G capabilities have been demonstrated.

Rival cellco Mobitel, meanwhile, announced on the same day the trial of what it termed 4.5G LTE-Advanced Pro (LTE-A Pro) technology, achieving top download rates of more than 1Gbps. The operator partnered with Huawei and ZTE to test the speeds in its lab, and claims that the 4.5G LTE-A Pro technology is capable of utilising a combination of 4×4 MIMO, 256 QAM and up to ’5CC [component carrier]’ to provide the gigabyte speeds.

According to TeleGeography’s GlobalComms Database, both Dialog (Sri Lanka’s largest mobile service provider in terms of subscribers) and Mobitel (the country’s second largest cellco), launched LTE networks in 2013, while Dialog moved on to initiate customer trials over an LTE-A network in July 2015, with a commercial launch expected this year.
