Mobitel is the pioneer in South Asia to launch a Super 3.5G HSPA network and successfully demonstrate HSPA+ Multiple Input Multiple Output (MIMO) technology. For the first time in South Asia, the Company successfully trialed 4.5G-LTE Advanced Pro technology with Carrier Aggregation (CA) of three bands in 2016 and in 2017, Mobitel was able to deploy the first Sub-1G Mobile Broadband Network in Sri Lanka innovatively to provide a broader 4G coverage in rural areas of the country. And also Mobitel launched the first commercial 4.5G/4G+ mobile network to provide an unparalleled broadband experience delivering burst speeds up to 300 Mbps to Sri Lankans in 2018. In April 2019, Mobitel was the first network in South Asia to successfully showcase the deployment of 5G over a mobile network by connecting a commercial mobile smartphone to its 5G network with a speed record of 1.55 Gbps and the first network to be recognised as the first mobile 5G network on the Ookla 5G map.
Mobitel unveiled the first 5G site at its store in One Galle Face, offering customers the opportunity to experience the true power of 5G with Mobitel and users who have 5G enabled smartphones can now experience Mobitel 5G technology at Mobitel X-Station. Mobitel is in the process to expand more 5G-experience locations around the country and expect to commence commercial 5G operation in near future with TRCSL commercial 5G license issuance. The Company has fuelled
over USD 700 Mn. worth of investments to date, shaping Sri Lanka’s ICT landscape experiencing exciting growth, poised to lead Sri Lanka towards an info com and knowledge rich society. Mobitel’s coverage extends nationwide and includes international roaming with the partnership of a global web of over 750 networks, to ensure digital inclusivity to all Sri Lankans.
Having pioneered 5G in Sri Lanka and South Asia and publicly demonstrating the first 5G Massive MIMO deployment over 3.5 GHz spectrum, Mobitel completed the First 5G Voice Call in South Asia successfully. During 2020, Mobitel displayed the transformational potential of 5G Technology, by telecasting the first 5G enabled Mixed Reality Live TV Show via its 5G Network in collaboration with SLT Peo TV - Charana TV Channel. By allowing geographically dispersed participants to be connected into the virtual events in real time, the telecast demonstrated how low latency and high-speed capabilities in 5G Technology can make virtual reality boundaries seamless.
Mobitel was the first mobile network operator to deploy a Sub-1G mobile broadband network utilising 850 MHz spectrum in Sri Lanka, increasing 4G LTE coverage across the island. In 2018, Mobitel commenced rolling out its largest-ever 4G LTE expansion project and deployed over 3000 LTE sites across the nation together with Voice over LTE (VoLTE), enabling customers to make high quality voice calls over the LTE network. Taking another innovative step towards the digital transformation, Mobitel provided a state-of-the-art LTE Critical Communications solution to a leading container terminal operator for the first time in Sri Lanka.
In recognition of the exceptional broadband network experience, Mobitel have been continuously recognised by Speedtest Awards by Ookla, the global leader in internet speed testing, as the fastest mobile network in Sri Lanka for the second consecutive year in 2019 and 2020. This is the third time that Mobitel has achieved this award, the first being in 2017.
Mobitel is capable of delivering coverage with increased penetration, with the launch of South Asia’s first NB-IoT network in the 850/900 MHz spectrum. This enable use by sensors, embedded deep within concrete structures or underground such as those required for smart meters, disaster monitoring sensors, and car park sensors. Mobitel have demonstrated the use of NB-IoT as a powerful technology in urban farming and home safety systems as well. Mobitel successfully provided connectivity to variety of commercial NB-IoT solutions island-wide and has conducted further PoCs and trials with many other industries to improve their efficiency and productivity.
