Turkcell prepares network for 5G with Massive MIMO tech

Turkcell, in collaboration with Huawei, has completed the first live FDD Massive MIMO technology test using the 1800MHz frequency band in Antalya, Turkey.

The test results show that 480Mbps cell throughput could be achieved by using eight commercial test terminals on the 20MHz spectrum with live network traffic.

“In order to provide the best experience for our customers, we are using tomorrow’s technology, today,” said Gediz Sezgin, chief network officer of Turkcell, providing information about the first test carried out in Europe and Central Asia.

“We continue to work intensively on our network in order to offer our customers the technology of the future. Thus, we aim to provide the best quality experience to our customers by offering the most innovative solutions. Again with the 'Massive MIMO' test we carried out in Turkey for the very first time, we are already preparing our network for 5G technology.”

Cell throughput increased more than five times compared to practical monitored throughput level in the same live network test area by serving traditional LTE 4x4 MIMO configuration. This collaboration is another innovative practice based in the TechCity project with Huawei. 

Turkcell, which is continuing to work towards 5G, has also strengthened its experience with the TDD Massive MIMO test, which was previously demonstrated in Ankara with a six-fold increase in cell throughput, with the FDD Massive MIMO test.

Massive MIMO technology, which has been developed in preparation for 5G, allows for a large number of people to connect to high speed internet at the same time in dense areas. Massive MIMO adopts large-scale antenna arrays and allows precise control of both horizontal and vertical beam widths and angles to realize user-specific 3D beamforming, channel estimation, and a user algorithm to multiplex time-frequency resources for different users. These collective activities help to maximize spectral efficiency, further enhance network capacity and improve overall user experience.

Sezgin added: “With the national and international collaborations, we are playing a leading role in the development of 5G technologies in the world. As the mobile operator performing the first speed test with real 5G equipment in Turkey, the know-how and experience gained through the collaborations we have entered into, we wish to bring our country to the highest level by becoming one of the few countries developing 5G technologies. Our aim is to develop local technology in 5G while also being one of the first countries in the world to use 5G.”
