Announced NTT East "Giga Raku 5G", inexpensive manager draw 5G service

　NTT East announced on March 1, 2022 that it will provide a corporate managed local 5G service "Giga Raku 5G" nationwide from May 2022.

　The career -grade 5G standalone (SA) function is provided as a local 5G, and one -package is provided from prior procedure to introduction and maintenance operation as a managed service.It is also characterized by a cheap cost of "one -fifth of the conventional price", and aims to introduce it to thousands in the next five years.

Daishi Masuyama, director of the NTT East Japan Business Development Division, who attended the press presentation, and Daisuke Saji, director of the company's network business promotion headquarters.

Build and use local 5G environment at the "1/5 of the conventional price" level

　Giga Raku 5G is a managed service that supports local / outdoor 5G provision.UPF (User Plain Equipment), Cu/Du, Ru (wireless device), and antenna are installed only at the customer base, and the local 5G environment is configured by connecting to the SA type 5G cores in the NTT East data center.。

　By installing UPF in a customer base, low -delay communication within the base can be enabled, and it can be easily connected to existing LANs.In addition, RU and antennas have a lineup of multiple types for indoors / outdoors, and can be selected flexibly according to the size of the cover area and the installation environment.

A rack containing UPF and an antenna will be installed at the customer base.The lineup of 5 outdoor antennas and one indoor antenna according to the area and directions of the area.First of all, it is a Samsung RU / antenna, but we will consider expanding including other companies' products according to customer needs.

　In addition, the work required for the introduction and operation of local 5G will be provided in one package as an IT outsourcing service.Specifically, it is a service from radio simulation at the introduction location to the arrangement of antenna / RU, network design, license acquisition (support), network and solution construction, network operation, monitoring and repair support.

　According to NTT East's estimation, the total cost of 5G and operation for 5 years is about 20 million yen (indoor installation / minimum configuration).The introduction of all of this costs about 100 million yen, which appeals to the fact that local 5G can be introduced at one -fifth levels.

　In addition, the 5g offer fee is provided with a subscription (monthly) type and lump -sum payment type.In the case of a subscription type, the basic usage fee (excluding tax) is 279,000 yen per month, and the indoor RU / antenna (integrated) is 31,000 yen per unit.Initial costs such as construction costs will be separate.Options include the addition of RU and antennas, and support for obtaining a license by the customer.

Solve all of the issues related to local 5G

　Daishi Masuyama, director of the NTT East Japan Business Development Division, explained the knowledge and issues gained in the past two and a half years since December 2019, when the local 5G system started in Japan. did.

　Starting with the establishment of a local 5G open lab in 2020 in 2020, the Tokyo DX Promotion Center, based on a three -party agreement with the Tokyo Metropolitan Government / University of Tokyo, starting with the Tokyo University Experimental Facility.We have been engaged in the construction of a local 5G environment at Tokyo Metropolitan University and participating in the regional issues solving demonstration developed by the Ministry of Internal Affairs and Communications.

　"I thought that local 5G would be an important part of private networks, so we opened a local 5G open lab in a pioneering manner."Many, many vendor base stations have been handled. "(Mr. Masuyama)

Initiatives for local 5G in NTT East

　On the other hand, companies that are considering using local 5G have heard voices of various issues."Costs are very high," "Specialized knowledge is required, it takes time to proceed," "System monitoring and troubles are difficult", "There is no way to introduce the test, it cannot be expanded from the test environment to the production environment."I want to introduce it in a form of adding a local 5G. "

　This time, Giga Raku 5G is positioned as a service that solves all these issues related to local 5G and promotes the spread of local 5G.

　Mr. Masuyama introduced the features of Giga Raku 5G into five large pieces.As already mentioned in this article, "Career -grade 5G SA functions are provided in total ITO (IT outsourcing) and one package", "Various lineups tailored to the usage environment", "Approximately 1/5 of the conventional price"There are five things: "All -you -can -use", "monthly / lump -sum payment can be selected and 5G data communication is unlimited", "cover and existing LAN can be used to add -on".

5 main features of Giga Raku 5g

　Another thing, Mr. Masuyama stated that "local 5G is very useful for building a private network, but we do not think that even if there is only a network, we do not think that we can promote customer DX and solve regional issues."He said he would further strengthen cooperation with companies and partner companies.

　"We will first provide high -quality and low -cost local 5G. Next, we want partners to develop various DX solutions on the premise that" local 5G can be used. "We hope that you can use local 5G to solve the industrial and regional issues when promoting pioneering initiatives. "(Masuyama)

Also supports semi -synchronous periods that can use wide bandwidth uplinks

　At the press conference, demonstration exhibitions of local 5G and solutions were also shown.

　In Giga Raku 5G, it is also possible to set the "semi -synchronous TDD" mode that increases the throughput ratio of the uplink.In general synchronous TDD settings, downlink up to 1488 Mbps / Uplinks up to 230Mbps, but in semi -synchronization, downlink up to 988 Mbps / Uplinks up to 466 Mbps (both theoretical values, uprinks are two -layer terminals).In the demonstration exhibition, the throughput of the uplink was measured, and the number of over 420 Mbps was stable.

Demo exhibition Actual measurement uplinks loopput

　One of the use cases was a demonstration that transmitted high -definition images of 8K cameras by locally 5G and used for advanced sites.For example, it is useful for facilities monitoring, such as opening and closing valves, analog meters, and intrusion monitoring of suspicious individuals and drones.If you enlarge the high -definition video, you can see the details, and you can expect a more accurate judgment in the AI processing of the video and performing abnormal detection.

One 360 ° camera (fisheye lens) is a wide area, but if it is enlarged, you can check the details.You can increase the number and types of cameras by taking advantage of wide -banded uplinks

In addition, use cases such as work guidance from remote bases using AR glass and grasping the harvest time of crops on farms were also introduced in demonstrations.
