To promote a secure communications environment across multiple Socio-Economic settings based on user needs and requirements
WGA is focused on discovering and promoting research areas that strive to understand the needs for and requirements to wireless future internet systems. The activities are based on the understanding that users are driving the creation and design of new, emerging applications and services in a secure environment. This includes the ‘direct’, traditional user requirements area: how the users are driving the creation and design of new, emerging services in a secure environment and how users will interact with devices, systems and applications in the Wireless World. It also includes ‘indirect’ user requirements in the form of ‘M2M’ communications. There is thus recognized an Increasing socio-economic impact on the Wireless development where the Future Internet will represent an increasing fusion between the digital and the physical world. User acceptance of this development requires attention to data protection, privacy and ethical issues. WGA addresses these challenges and investigates the sphere of user requirements and interaction between users, devices, systems and applications and studies the elements of viable business models under different socio-economic conditions.
The approach and focus of the WWRF is at present being sharpened to better align with the technology innovations and industry directions in networking and communication. As a result, the Working Group C, while building on its successes, is being revitalized to speed-up and facilitate the convergence of software, cloud, big data, virtualization and networking. It is the WGC’s endeavor to pool industry and academic resources to do targeted applied research to identify challenges facing the industry with this convergence and propose solutions that are pragmatic in the short-term (with backwards compatibility) and strategic in the long-term to evolve to what ideally they should be.
The group’s mission is to guide the mobile industry in the use of software, virtualization and cloud computing in future networks (both wireless and wired) by developing end-to-end network architectures, identifying the specific requirements and issues and addressing them by providing solutions that are practical and business driven, and thus accelerate the adoption of 5G where IT will play a major role. Virtual network slicing to develop custom networks for specific industry verticals and services from the common underlying physical infrastructure will also be an important mission of this group.
Until now the working focused on the vision and tasks that were guided by the architecture depicted in Figure 1 below, resulting into several widely cited white papers and outlooks. These accomplishments will now form the foundation of the future activities of the reorganized working group, as depicted in Figure 2.0, and will primarily focus on the softwarization, virtualization and slicing of the 5G and future networks where IT will play an important role.
Main topics that WGC covers are focused on:
WGD addresses research aspects focusing on the air interface for wide-area and local-area wireless communication systems, spectrum issues and other distributed resource sharing for the wireless Future Internet.
In particular, WGD covers topics such as multi-carrier air interfaces, smart antenna technologies, cooperative communications, interference management, cross-layer (PHY/MAC) design, overhead signalling and complexity issues, advanced White Space Devices (WSDs). Physical-layer security of wireless systems is also covered in this working group.
As wireless networks evolve beyond IMT-Advanced, challenging requirements resulting from the ever-decreasing cell size along with the explosive increase in the number of cells and the number of users and devices to be connected, breaking the interference barrier and maintaining the per user/node capacity will need powerful PHY/MAC cross-layer design and emphasis on the optimization of performance versus complexity/overhead trade-off. Moreover, an interactive and reliable radio resource sharing mechanism covering technical and technological aspects will need to be studied. Hence, a secure liberalized radio environment would be one of the prime targets of the wireless FI ecosystem.
It is envisaged that WGD will address the groups of research areas identified in the following subsections.
New Air Interfaces design
Novel system concepts
Requirements for Spectrum Management
Spectrum management aspects in the FI era
WGD White Papers
The mission of the WG-Cybersecurity is to promote a trusted and cyber secure environment for the current and future wireless technologies through the identification of key research challenges and technology trends.
Workshop on Cybersecurity on 1st April 2022
With the mission to promote a trusted and cyber secure environment for the current and future wireless technologies through the identification of key research challenges and technology trends WWRF organised a virtual workshop on 1st of April, WWRF WG-Cybersecurity on “Cybersecurity in 5G Beyond” The workshop had good representation from the Industry and Research Institutions. The topics for the talks were:
WWRF provides a platform to the global wireless research community to explore and develop the research challenges that confront us as we look beyond current 5G and other developments. These developments have raised considerable concerns in the cybersecurity sector.
WG-Cybersecurity focuses on addressing these concerns and provides a common ground to researchers and Industry representatives to explore these challenges. The group takes the multifaced approach to cybersecurity due to its complexity as there are multiple threat vectors, increasingly sophisticated and effective attacks, and a general lack of suitable security standards.
To support our mission of “a trusted and cyber secure environment for the current and future wireless technologies” the WG-cyber will focus on following areas.

In recent years, data rates in wireless communication have doubled every 18 months[i]. Extrapolating on this trend, wireless data rates of 1 Tbit/s per data link can be anticipated by the year 2030. These data rates are far beyond what the current 5G wireless vision is hoping and what is possible even in current "wired" systems, which are working towards a 400 Gbit/s Ethernet today. Higher frequencies (above 6 GHz) radio communication technologies are expected to play a significant role in realising this vision of wireless transmissions towards the region of 1 Tbit/s.
Due to the ultra-large bandwidth required to achieve such data rates, carrier frequencies of tens or even several hundreds of GHz bandwidths are necessary compared to present 5 -20 MHz. To achieve the goal of data rates of 2-3 orders of magnitude higher compare to the current 5G vision, fundamental research, system and channel modeling and enabling technologies in the following three technological key areas are required:
[i]S. Cherry: “Edholm’s Law of Bandwidth,” IEEE Spectrum, Vol. 41, No. 7, 2004.
To provide a discussion platform/thinktank, by engaging a critical mass of experts from industry, regulators and academia, in order to investigate/understand the trends, requirements, enablers and challenges in the specification, design, optimization and adoption of high frequencies radio technologies in future wireless networks.
Several organizations have already expressed their interest to participate in this activity and have contributed to the workshop organized by WGD at WWRF35 in October 2015 under the theme of “Channel Modelling and Technology Enablers in mmWave and THz bands - Evolution beyond 5G”.
ITU-R WG A& D have indicated that they are interested in receiving contributions on the subject matter. Preliminary discussion s with ITU-R WP5A has shown interest in organizing a workshop on 275GHz and above.
It will be also necessary for this group from time to time to look at near term issues in order to help industry stakeholders assess / direct the technology evolution path (which is an important factor for service providers and for their investments.)
WP1: Channel Modelling for mmWAVE and THz radio communications – Requirements, Challenges, State of the Art and Global Initiatives
WP2: Air Interface and Wireless Access technologies for mmWave and THz radio communications – Challenges and Trends and expected Impact

To peer into what is next to come after 5G (B5G) leading to the development of the standards for 6G, required research into the enabling technologies and how it is likely to be commercialized. Nothing succeeds without the compelling use cases, applications, and innovations in business models; therefore, this group will also be vigilant about these non-technical aspects to augment its work on technologies and standards to present a holistic view of the launch of the 6G era.
The 6G Vision and Technologies Group focuses on research that looks five to ten years ahead in order to meet the requirements of the networks in the year 2030 time-frame. The group looks into the gaps in 5G that would need to be filled, resulting into incremental changes to 5G, called B5G until such time that clear requirements of 6G have been determined and needed research areas identified. The group also aims to study the emerging new use cases that will require 6G, and the potentially novel business models to justify investments that will be needed.
Areas of focus
The major companies, universities and organizations active in 5G, B5G and 6G are most welcome to join the 6G Working group.
Develop an e/m-Health and wearables vertical industry paradigm to expose the requirements of such systems (HaaS) to be 5G enabled. Get the experts from this vertical industry involved in the WWRF VIP and beyond.
The objectives of the e/m-Health and wearables Vertical Industry Platform (VIP) are to:
Figure 1. 5G in e/m-Healthand wearables
The above objectives will be realised by investigating various evolutions in healthcare by selecting a specific domain and focusing on the following:
Case study parameters (and KPIs)
Stakeholders approached (and we have positive feddback)
The Vertical Industry Platzform (VIP) Rail study group focuses on research that looks five to ten years ahead to meet the requirements of the railway industries based on the next generation wireless technologies. It is also aimed to identify and discuss new and vital use cases for these industries.
As the global process of developing the 5G (NR) platform is progressing at remarkable speed, both in terms of the identification of the market need, standardization aspects and spectrum related matters, where sets of “pioneer bands” already has been adopted across Regions, a need is emerging to focus more closely on the Professional Sectors, in this case the national Train Service Authorities, and the potential benefits and hurdles for their future adoption of what today is known as 5G.
As train services across the world offer higher speed trains, the need for operational radio communications systems and Internet of Things (IoT) are also pushing this aim.
Security, reliability, safety, resilience, IoT and dependability are playing a focal role in future radio communication systems for efficient train operations.
Furthermore, VIP Rail study group should also consider participation in the ITU-R activities, that are being initiated based on the decisions of the ITU-R World Radio Conference 2019regarding choice of harmonized spectrum for train to track communications.
Milestones and deliverables
Outputs include white papers and technical proposals which will be submitted to the major standardization bodies of 5G, including ITU and 3GPP.
Invite major companies, universities, and organizations active in the area of railways
The Vertical Industry Platform (VIP) focuses on research that looks five to ten years ahead on Business Models (BM´s) supported and enabled by 5G and Beyond wireless technologies in order to meet the requirements of future Business Model Ecosystems (BMES). It also is aimed at the identification of user and business cases for these BM´s and BMES.
Companies, universities and organizations have shown interest in the activities and will be contacted after the approved launch.
