Nokia and Zain Saudi Arabia have conducted a trial of advanced 4.5G features including uplink carrier aggregation, 4X4 MIMO, downlink 256 QAM as well as uplink 64 QAM, to achieve higher throughput. The trial took place in Jeddah.

The operator is striving to improve the mobile broadband experience for its subscribers.

Eng. Sultan Abdulaziz AlDeghaither, CTO, Zain Saudi Arabia, said: "With the exponential growth in the demand for ultra-high-speed mobile broadband services in the Saudi market, we continue to invest in our network and adopt the latest technologies available on the market. With this successful trial with our partner Nokia, we are confident that our network will evolve smoothly toward 4.5G Pro, 4.9G and 5G."

"Due to the rapidly growing use of data-hungry applications by smartphone users in Saudi Arabia, future networks will require a very high network capacity and throughput to deliver gigabytes of data. With our future-proof technologies, we are committed to helping leading operators like Zain Saudi Arabia evolve their network to address this," said Ali Al Jitawi, head of the Zain Saudi Arabia Customer Team at Nokia.
