Vodafone Group’s Networks Centre of Excellence team and the Huawei Mobile Innovation Centre completed the world’s first trial of GSM/LTE (GL) 900MHz dynamic spectrum sharing on Vodafone’s commercial networks in the Black Coast city of Trabzon, Turkey. The teams have been testing a dynamic way to help address capacity issues in Turkey, according Telecompaper. In 2017, Vodafone and Huawei achieved unparalleled overlap by GSM (2G) and LTE (4G) services within the 900 MHz spectrum band. With this trial, they have shown that it's possible to assign that spectrum dynamically, namely available 900 MHz can be allocated between 4G/LTE and 2G services based on customer demand.
In the trial, which took place over several months, dynamic sharing allowed Vodafone Turkey to provide up to 10MHz of 4G/LTE capacity and throughput in a very effective way. 4G/LTE KPIs clearly show the improvement in network performance and better user experience. The test cases showed that download and upload throughput improved by 20 percent.
