Vertical Testbeds: Designs, Implementation Experiences, Obstacles and the role of Open Source
One of the main goals of a testbed is to demonstrate and validate newly designed and developed technology components. Typically, in order to accomplish this objective, it includes integrating a large number of diverse technology elements in a common framework where different trial sites and components can be interconnected in a variety of configurations depending on the requirements. The resulting highly integrated platform is then used to not only experimentally validate individual components but to also, verify whether the overall system can satisfy the stringent requirements imposed by the verticals.
The integration of these diverse technology elements and their deployment can be materialized through a Testbed implementation realizing the full potential of 5G working in tandem with the open-source ecosystem. 5G networks need to support diverse requirements and services. Thus, a focus of their design is on supporting disaggregated network functions that are modular, flexible, supporting extensible open interfaces and cloud-native in all aspects. Open source must adopt and demonstrate these design principles in order to successfully integrate into advanced wireless networks.
The Testbed Vertical track intends to introduce the challenges that 5G aims to solve with regard to the spectrum demand and the convergence of different wireless communication services. In addition, the track looks for overseeing the applicability of certain open source projects in 5G.
The Testbed Vertical Invited Talks will provide a venue for leading experts in the world to showcase and discuss the design of testbeds for experimental validation and trialing of a number of emerging 5G vertical applications. These invited talks will feature highly influential speakers who have directly contributed to successful 5G Testbed deployment and vertical applications in their respective fields. The talks and discussions will focus on innovative and leading-edge, large-scale industry or government applications of 5G Testbeds in areas such as health-care, bio-informatics, public policy, infrastructure, telecommunications, automotive and transportation, rural and agriculture, aerial, public safety, education, defence, and space.

Title: “What can Virtualization do for 5G Networks: Our experiences of building a 5G Testbed”
Abstract of the Talk: In order to enhance 5G R&D capability in India and increase our participation in global standardization activities, a 5G Testbed project involving a few of the prominent technical institutions of the country was initiated by the Department of Telecom, Govt of India in the year 2017-18. Some of the other goals of the project are to boost product design & manufacturing in the country and also encourage telecom product start-ups. As a part of the 5G Testbed project, we have been working on the development of the Core Network components and the support for WiFi access in 5G Networks. We are also developing a Multi-RAT SDN Controller to control and manage multiple radio access technologies in a unified manner. The 5G Testbed utilizes SDN and NFV, two key virtualization techniques as fundamental building blocks. With the help of SDN & NFV, we have been able to virtualize the complete 5G network and deploy it fully in the cloud. Interestingly, one of the unforeseen takeaways of the virtualization is that it has enabled us to continue the development & testing activities “virtually” uninterrupted during this pandemic. The talk will highlight our experiences of using these virtualization techniques in the testbed and the advantages they may bring.

Title: “Experience sharing from Wipro’s 5G lab” (Pre-recorded)
Abstract of the Talk: 5G network is expected to transform the industry verticals by enabling new use cases with its programmable interface and its ability to offer assured network quality for demanding requirements involving low latency and high bandwidth scenarios. While network has traditionally been built and operated by communication service providers, there are opportunities for vertical industry to build and operate private 5G networks. While network slicing is expected to offer use case specific network services through a public network, the market is divided on the way private network will evolve. To bring clarity, there is a need to create reference industry use cases, learn from it and make a decision on how the vertical application can leverage the new network capabilities through the open APIs. This session will touch upon the challenges for the industry verticals in re-imagining their applications leveraging 5G edge computing, open APIs, AI and real time network analytics to enhance experiences and value. The session also will share learning from sample industry applications developed in Wipro Lab.

Title: “India’s Ascent on the 5G Ladder” (Pre-recorded)
Abstract of the Talk: The advent of 4G technology has led to radical changes all over the world, especially by way of smart phones that have had a staggering impact on our lives. Far from being a mere evolutionary successor of 4G, 5G technology is slated to revolutionize the telecommunications sector in the near future. 5G technology will go much beyond connecting people – 5G applications include integrating a whole range of machines into the internet, such as smart metering (electricity/water/gas), industrial sensors, tracking of people/assets, machined farming, agri-tech, perishable goods management, pollution monitoring, healthcare applications, video surveillance etc.
Given that critical national infrastructure such as electricity grids, and various public services offered by local Government bodies will soon run on 5G, security considerations are crucial in the selection and ownership of such technology, as it will have a bearing on the nation’s ability to control the equipment as well as secure the delivery of such critical services. On the economic front, within the next decade, 5G/IoT is expected to add hundreds of Trillions of USD to the world economy. This is an unprecedented economic opportunity that India cannot afford to let go of. So far, only a few Indian entities have begun to address such opportunities in the 5G/IoT space.
Recently, the Department of Telecommunication (DoT), Government of India, has sanctioned the “Indigenous 5G Testbed” program with a project outlay of 224 crores INR. This program, started yielding results in the form of prototype base stations, CPE/UE and NB-IoT chipset that are being demonstrated under lab conditions. One of the partner institutes in this project (IITH), has major contributions to key 5G technologies such as cloud RAN base station with massive MIMO capability, 5G UE prototype, and cellular NB-IoT chipset for connecting sensors and meters to the internet. IITH is expected to demonstrate these 5G prototypes during 2020.
In this talk, Prof. Kuchi will first discuss the 5G scenario in India and the unique Indian requirements that 5G is expected to address. This is followed by a tech talk that highlights his efforts in designing 5G NR technology. The talk will comprise of video “demos” followed by a Q/A session.
