China Mobile Reached One Billion Subscriptions
China Mobile confirmed the position of the largest mobile player in the world by connections.
BT Group, Nokia, and Qualcomm successfully finished the first test of 5G carrier aggregation using five components in Europe. The technology is expected to achieve improved capacity and greater downlink speeds for users in high-demand areas.
The trial took place at BT’s facility on the live spectrum using a Nokia kit and a device with a Qualcomm Snapdragon modem. It formed part of the operator’s preparation for the launch of its EE brand’s standalone 5G network later this year. Tests of the system achieved downlink speeds of 1.85Gb/s using three FDD carriers aggregated with two TDD ones. They had a combined bandwidth of 150MHz.
Nokia and BT claimed the use of five component-carrier carrier aggregation (5CC CA) would boost data rates in high-demand areas by combining all mid-band radio spectrum when a standalone 5G device requires a high-speed connection. When EE’s standalone network launches, the operator will also have the ability to use a low-frequency sixth carrier to provide a superior experience in more places, including indoors.
The test represents the latest demonstration of carrier aggregation conducted between the partners as BT prepares to launch standalone 5G, a technology the operator’s chief networks officer Greg McCall has highlighted numerous times as one it would not bring to market until it was able to provide a sufficiently differentiated service. McCall said in a statement BT wants to build further on the benefits of carrier aggregation in delivering greater throughput and speeds to customers. This is particularly important as more and more devices come to market with 5CC CA capabilities.
