The second largest mobile operator in Sri Lanka and a subsidiary of Sri Lanka Telecom(SLT), Mobitel announced that it has successfully trialed the 4.5G LTE-Advanced Pro technology which is capable of achieving speeds exceeding 1 Gbps. The trial was conducted in partnership with Huawei Technologies and ZTE Corporation in Mobitel’s test lab.
4.5G LTE-Advanced Pro Technology is capable of utilizing a combination of 4x4 MIMO (Multiple-Input Multiple-Output) ; Higher Order Modulation 256 QAM (Quadrature Amplitude Modulation) and up to 5CC (five-component carrier) to provide Gigabit speeds for end users. According to Mobitel, it is looking to commercially launch 4.5G services soon to enhance user experience, especially for time-critical applications such as voice, video and on-line gaming.
Claiming the test to be the first in South Asia, the operator said that it was also the first operator in the region to introduce a number of other key technologies with the launch of Super-3.5G HSPA network in December 2007, and the trial of HSPA+ and MIMO (Multiple Input Multiple Output) in 2009 and the demonstration of the 4G-LTE technology in 2011.
