IIJ Opens the Shiroi Wireless Campus for a Hands-on Experience of the Latest Wireless Technology

Applying for a local 5G wireless license for the Shiroi Data Center Campus

November 6, 2020

TOKYO-November 6, 2020-Internet Initiative Japan Inc. (IIJ, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced that, starting November 9, 2020, it will open its mobile technology testbed "Shiroi Wireless Campus" to the public, so they can experience the latest mobile technologies. The Shiroi Wireless Campus is a part of the Shiroi Data Center Campus (Shiroi DCC), which began operations in May 2019 in Shiroi-city, Chiba Prefecture.
Having positioned the Shiroi DCC since its opening as a place to conduct experiments necessary to developing new services, IIJ built an experimental site with indoor and outdoor wireless base stations. There, IIJ will showcase various demonstrations using mobile technologies. The Shiroi Wireless Campus will be open to the public as a facility where customers can experience hands-on the latest wireless communication technology.

Background

Many IIJ customers have expressed interest in trying local 5G, private LTE (sXGP), and other advanced wireless communication technologies, but in most cases, they have not yet considered their specific usage scenarios and implementation requirements. This situation is due to the fact that many advanced wireless technologies are in the processes of standardization, product development, and under regulatory discussions. That has limited the number of compatible devices and facilities available in the market, making it difficult to verify and evaluate wireless technologies' capabilities, and to get a clear picture of how the technology would work in practice. Therefore, IIJ thought to gather a wide variety of wireless communication technologies in a single location and to provide a place for customers to experience the features and capabilities of each through demonstrations and exhibitions. It can be used as a testbed environment for wireless device manufacturers to verify new device operations and test interoperability with core network, where they can apply to conduct proof-of-concept activities of wireless communication network in collaboration with their customers.

Exhibits

The following demonstrations are available:

1.Automated hand-over between private and public LTE
Visitors can experience automated switchover of the radio networks when moving between private LTE and public LTE areas(*1) reciprocally.
2.Remote monitoring and control of security robots via private LTE
Private-LTE-controlled security robots (ALSOK's REBORG-Z) patrol around the Shiroi DCC and attend to visitors. In the future, it is planning to use multiple private LTE base stations to demonstrate the seamless movement of security robots inside and outside the building, as well as a secure communication environment on a closed network.
3.Wi-Fi6
This demonstration compares Wi-Fi6's capabilities with Wi-Fi5's speed, showing a significant communication efficiency improvement in crowded environments.
4.LoRaWAN®, a wireless communication technology for the IoT
This exhibit showcases LoRaWAN®-compatible IoT sensors and a user interface of IIJ's IoT service.
5.Video transmission over a wired network that emulates local 5G StandAlone (SA) radio network
This demonstration uses 3D motion sensors to allow computer operation through finger movements. Real-time processing of 3D dynamic analysis using MEC(*2) that combines with the 5G SA mobile system allows users to experience a world of ultra-low latency and enhanced broadband local 5G networks.
6.Cellular LPWA (LTE-M) and SoftSIM
This exhibit introduces a gadget that combines cellular LPWA, which enables wide coverage and low power consumption through mobile carriers' wireless networks, with IIJ's SoftSIM, which is useful for reducing the size and power consumption of terminal equipment.

Floor plan

Future plans for local 5G

Regarding the local 5G Non-StandAlone (NSA) installation, IIJ plans to procure regional BWA(*3) and 5G NR(*4) wireless base stations from Grape One Co., Ltd., a joint venture between IIJ and Sumitomo Corporation. In addition, IIJ is currently in the process of applying for a local 5G frequency assignment for the Shiroi Data Center.

Regarding the future local 5G SA installation, IIJ plans, starting in June 2021, to build a testing environment using 5G NR that combines core networks and wireless base stations provided by domestic manufacturers. This project is in line with the allocation of sub-6 GHz frequencies (the sub-6 band) for Local 5G scheduled for the end of 2020.

  • (*3)Regional BWA: The wireless communication system using 2.5 GHz frequency aimed to correct inter-regional information disparity and improve public welfare.
  • (*4)5G NR: A new wireless technology that supports a wide range of frequency bands, including millimeter wave wireless, capable of meeting the high demands of 5G. This technology is being developed as the replacement of LTE.
  • (*)In radio wave measurements and other tests, IIJ uses Viavi Solutions' CellAdvisor 5G, a compact all-in-one base station analyzer compatible with 5G NR (sub-6 and millimeter wave). This 5G base station analyzer has a spectrum analyzer, a beam analyzer, and the area mapping functions needed to measure wireless zones. It has applications in the research and verification of wireless access networks.

IIJ will continue to actively promote and disseminate new wireless communication technologies through research and development, and through demonstrations at the Shiroi Wireless Campus.
