MTN and Ericsson trial first LTE-U network --

MTN SA and Ericsson have successfully tested LTE-Unlicenced (LTE-U) at MTN s flagship channel store in Morningside, Johannesburg. This is the first LTE-U trial in Africa. LTE-U is a mobile technology innovation that enables higher data speeds, which increase network capacity and significantly enhance customer experience.
The LTE-U trial was completed by aggregating 10MHz of MTN s licensed 1800MHz spectrum and 20MHz within the unlicensed 5GHz band. The trial achieved a throughput of more than 200Mbps. The aggregation of licensed and unlicensed spectrum in indoor small cells is a key enabler for 5G.
LTE-U is designed to take advantage of the capacity available in the unlicensed 5GHz band spectrum. Through aggregating licenced spectrum with unlicensed spectrum a bigger LTE carrier is created. The ability to aggregate spectrum is one of the primary benefits of LTE. Using this technology, MTN is able to combine its LTE spectrum with portions of the 5GHz spectrum band, to enable LTE- Unlicensed, said Krishna Chetty, acting chief technology officer, MTN SA.
The lack of critical high value spectrum has compelled MTN to combine existing licensed mobile spectrum with unlicensed 5GHz spectrum to cater for the rollout of new generation networks such as LTE-U. Chetty said it will offer MTN s customers a great network experience because it packs more speed into the same site, which should allow more people to access the network simultaneously, while improving the overall customer experience.
Henrik Linnet, head of practice mobile broadband, Ericsson Sub-Saharan Africa says: We are very excited to trial LTE-U with MTN in SA. This solution when fully operational will allow MTN to boost data speeds and coverage in the cellular network and support the growth of indoor traffic, by using the unlicensed 5 GHz band already populated by Wi-Fi devices.
This is the first LTE-U trial and first enhanced CSAT (Carrier Sensing Adaptive Transmission) functionality demonstrated in Africa. Through this, we demonstrated that LTE is a good neighbour to Wi-Fi, said Linnet.
This application is currently suitable for in-building LTE deployments, due to the characteristics of unlicensed spectrum in the 5 GHz band, meaning that where there is dedicated in building MTN LTE coverage, one can expect great data speeds.
Thus far, our tests to demonstrate LTE-U have only been performed using a non-commercial prototype device, however we expect commercial devices that support LTE-U to be available in the market later this year. A demonstration can be had at the MTN store in Morningside.
