With packet core, NECI paves the way to launch NTT DOCOMO's 5G standalone (SA) services!


 NTT DOCOMO, INC. (DOCOMO) commenced commercial 5G standalone (SA)-based services on December 13, 2021, with NECI providing packet core (5GC) and base stations (5G RUs, CU/DU).

The cloud-native design of NECI's 5G Core for SA, which includes container and Control and User Plane Separation (CUPS), enables flexible operation for various services. NECI's 5GC for SA also uses network slicing technology to develop customized networks on-demand to meet the needs of 5G services like eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low Latency Communications).

Furthermore, NECI's 5G CU/DU, which was previously operating on DOCOMO's commercial network as a non-standalone (NSA) device, has been smoothly upgraded to 5G SA via a software upgrade in conjunction with the 5GC as mentioned above.

"5G SA enables the supply of networking solutions that can adapt to a wide range of use cases," NTT DOCOMO Senior Vice President Hiroshi Kobayashi stated. "Through its 5G SA, NTT DOCOMO will contribute to the creation of new value and the resolution of social concerns, as well as support the continued advancement of its 5G network to make its customers' lives more easy and prosperous," says the Company." "It's a pleasure to have been a part of the commercial launch of NTT DOCOMO's 5G SA services." the Company further added.

NECI's Executive Vice President Atsuo Kawamura further stated,” By offering high-quality and dependable 5GC and base station equipment, we will help DOCOMO expand its 5G services, while also contributing to the continued development of next-generation mobile infrastructure across worldwide markets."

What Is 5G and How Does It Work?

Radio frequencies (also known as a spectrum) are used in wireless communications systems to transmit long distances.

5G is similar to 4G. However, it uses higher radio frequencies that are less crowded. This phenomenon enables it to transport more data at a much faster rate. Millimeter waves are the higher frequency bands (waves). Regulators have opened them available for licensing after they were previously unlicensed. Because the necessary equipment was both unavailable and expensive, they had mostly gone unnoticed by the general population.

While higher bands are faster in carrying data, sending across long distances can be problematic. Physical objects, such as trees and buildings, can easily block them. 5G will use numerous input and output antennae to improve signals and capacity across the wireless network to overcome this difficulty.

Tiny transmitters will also be used in the technology. Instead of employing single standalone masts, they are mounted on buildings and street furniture. According to current predictions, 5G will accommodate 1,000 more devices per meter than 4G.

A physical network can also be sliced into several virtual networks using 5G technology. Operators will supply the appropriate network slice based on how it is being used, allowing them to manage their networks better. 

This process means that, depending on the importance of the task, an operator will be able to choose varying slice capacities. The planning team might segregate simpler devices from more complex and demanding applications, such as managing driverless vehicles. A single user streaming a video would use a different slice of a corporation.

Businesses will also rent their own segregated and insulated network slice to distinguish them from other Internet traffic.
