The FINANCIAL — Marking an important step in the research and standardization of 5G technologies, NTT DOCOMO, INC. (DOCOMO) has partnered with Nokia Networks to explore and harness the potential of Nokia Networks mmWave technology in the 70 GHz spectrum band.
In a joint indoor 5G trial, the two companies achieved downlink speeds of more than 2 Gbps using higher frequencies in the 70 GHz band. This development underscores the operator’s readiness to deliver a state-of-the-art 5G network in 2020 and beyond. DOCOMO and Nokia Networks are also planning to conduct a 70 GHz outdoor trial later this year, according to Nokia.
Solution details at a glance:
Proof of Concept system was demonstrated using an access point and equipment with 1 GHz bandwidth in a laboratory environment
Feasibility of Nokia Networks mmWave wireless communication showcased with a mobile terminal in the 70 GHz band
5G PHY and MAC software enabled beam tracking for pedestrian mobility and more than 2 Gbps throughput
Seizo Onoe, CTO, NTT DOCOMO, INC., said: “Utilizing higher frequency bands including millimeter wave is key to deliver extremely high performance in 5G. We believe that high-frequency spectrum shall be used not just for small cells as a means to complement the existing network, but also for building solid area coverage through coordination with existing lower frequency bands. The success of this indoor trial with Nokia Networks using the 70GHz band marks an important step forward in our 5G vision for 2020.”
Hossein Moiin, CTO, Nokia Networks, said: “Moving ahead on our pledge to cooperate on 5G research and innovation for developing and validating 5G, we have laid a strong foundation for realizing DOCOMO’s 5G vision. We will ensure that our focus is clearly trained on helping the operator monetize the immense revenue potential of future-ready technologies to effectively address ever-increasing network coverage and capacity requirements.”

Wireless data traffic will grow 10,000 fold within the next 20 years due to ultra-high resolution video streaming, cloud-based work, entertainment and increased use of a variety of wireless devices. The company also foresees that 50 billion devices will be connected to mobile networks by 2025 (the IoT era). Extremely low latency and high capacity are needed for future use cases, and 5G is expected to meet those requirements.
