1. Introduction

The main theme of Tsukuba Forum 2019 was “Supporting the present, shaping the new era—World-leading technology for creating services and field front-line technology for transforming operation/maintenance.” It was held with the intention of creating a smart world with NTT as Your Value Partner as it looks back on network access technologies that have supported society to date and pioneers new access networks of the future. In addition to NTT Access Network Service Systems Laboratories (AS Labs), 105 organizations, including co-hosting organizations and NTT Group companies (Table 1), participated. They introduced and exhibited the latest research and development (R&D) and technological trends.

3.1 Workshop 1

Mr. Kazuo Kitamura, business unit manager of the AI and Robotics Business Headquarters, Robotics Solutions Business, NTT Advanced Technology Corporation, gave a lecture titled “WinActor Business Overview.”

Mr. Kitamura first gave an overview of WinActor. WinActor is a client PC (personal computer)-based robot process automation (RPA) tool developed by NTT research labs in 2010 with its unified management support system technology. It was commercialized by NTT Advanced Technology and released in 2014. As of the first half of 2019, over 4000 companies have adopted this software, giving it the largest RPA tool market share in Japan. Over 700 companies are currently sales partners of this software.

Next, Mr. Kitamura described WinActor’s three major features: simplicity, support, and scalability. New functions to strengthen the product and promote simplicity include a new service called Cast on Call, which provides ready-made scenarios for task automation, contour matching, and enhanced virtualization support. Version 7, slated for release in 2020, will feature a refreshed user interface (UI) and multilingual support. Mr. Kitamura also discussed personnel training to bolster support and gave examples of WinActor’s management functions and enhancements for achieving scalability. He argued that to further strengthen collaboration with work applications for digital transformation (DX), the key issues are how to migrate WinActor to the cloud and implement on-premise and cloud collaboration and how to use artificial intelligence (AI) in areas where human judgment is required, which is not stereotypical, thus considered an area RPA tools are poor at.

Finally, Mr. Kitamura stated that NTT Advanced Technology is further pursuing customer’s DX by increasing customer value when using WinActor together with all NTT’s partners through the Technology Partner Program established in July 2019.

3.2 Workshop 2

Mr. Minoru Tanaka, executive research engineer and supervisor of the Civil System Project, AS Labs, gave a lecture titled “R&D Trends in Technologies for Maintaining and Managing Telecommunication Infrastructures.” For details, see the article in this issue [3].

3.3 Workshop 3

Mr. Takeshi Onizawa, executive research engineer and executive manager of the Wireless Entrance Systems Project, AS Labs, gave a lecture titled “Wireless Systems Technologies for Present and Future Services.” For details, see the article in this issue [4].

4. Two-day events

4.1 30th Tsukuba Forum Exhibit

The evolution and the future of access network technologies were showcased. Changes through the eras and transformation of systems were exhibited. Some visitors viewed the exhibit nostalgically, and many said, “I could easily understand how things changed” (Photo 4).

4.2 Panel discussion

Co-hosting organizations, NTT Group companies, and the NTT research labs united to introduce efforts and hold salon-style discussions on two themes: “Next-generation optical fiber cable technology” and “New wireless developments in the Reiwa era*.” The panelists introduced examples from different companies. Many attendees commented, “I learned a lot” and “It was extremely interesting” after listening to discussions about specific challenges for the future and different companies’ views (Photo 5).

4.3 Radio equipment supporting the local community and disaster preparedness

A video presentation on wireless facilities that support safe living in remote islands and mountain areas and prevent the isolation of affected areas during disasters was given.

4.4 Stamp rally

A digital stamp rally using smartphones was carried out for the third time at Tsukuba Forum 2019 to enable visitors to navigate throughout the exhibition hall of AS Labs. Those who gathered the seven stamps in the venue were awarded an original utility pole number tag. When the souvenir was handed to the participants, they remarked, “I look forward to this every year” and “I want to collect the utility pole number tag every year.”

* Reiwa is the name of the current Japanese imperial era, which began on 1 May 2019.

5. Overview of exhibits

In addition to exhibits from AS Labs, exhibits on the latest technologies of the co-hosting organizations and NTT Group companies were held (Photos 6 and 7).
