LOCUS - Localization and analytics on-demand embedded in the 5G ecosystem, for ubiquitous vertical applications.

The LOCUS consortium gathers a diverse blend of high-profile partners from Telco and IT industries that can make its vision a reality. LOCUS will be an enabler of a myriad of applications for the 5G ecosystem and beyond, boosting vertical industries and creating new business opportunities also for telcos.

LOCUS will augment current and future infrastructures to: i) provide accurate and ubiquitous location information as a network-native service and ii) derive more complex features and behavioural patterns out of raw location and physical events, and expose them to applications via simple interfaces. Localization, together with analytics, and their combined provision “as a service”, will allow network operators to better manage their networks and to dramatically expand the range of offered applications and services.

The VIAVI innovation participation includes:  

  • Localization analytics exposed as virtualized services on top of hybrid edge/core virtualization platform integrated with 5G network infrastructures
  • People (individual and group) mobility analytics as virtualized network functions

6G Knowledge Hub

Network investment and deployment is expensive. Planning, deployment, operations, management, and performance of the mobile networks must be made more efficient for operators to see ROI on 6G. Approaches and technologies associated with 6G will help enable these efficiencies in a way we’ve not seen with previous generations. 

Sustainable Development Goals including climate goals 

  • The UN has outlined 17 Sustainable Development Goals (SDGs) which form part of a 2030 Agenda.  
  • Interestingly, 2030 is also the date that commercial networks are expected to go live. 
  • A number of service providers have also marked 2030 as a key date for 6G. 
  • 6G could have a range of positive environmental and socio-economic benefits, allowing telcos and enterprises to work towards SDGs. 
  • Tech: will draw on this report which identifies potential solutions that could be incorporated within 6G networks to reduce energy consumption and be more sustainable.  
  • Socio-economic: investing in new, better wireless connectivity (especially in rural areas and developing economies) will help address a number of the UN’s SDGs, improving access to education, narrowing the digital divide, improving remote healthcare, creating more sustainable, connected cities etc. 
  • In the future, there may be environmental/sustainability/net-zero regulations that telcos have to adhere to – or which are set by trade orgs and are a requirement of a telco’s membership. Developing 6G technology may therefore be critical in future-proofing a telco business and adhering to frameworks/regulations/legal requirements.  
  • Market and economic drivers 
  • 6G will enable new kinds of experiences, which can be rolled out to more end users with a guaranteed QoS for each end user.  
  • This include VR, AR, MR, 3D networking, UAVs, autonomous cars, optical wireless comms, AI. 

6G Technology Enablers

Many of today’s test approaches (testing as early in the dev cycle, comprehensive testing of subsystems as well as overall performance testing) will continue to apply as the technology evolves.
Considerations on how testing will need to evolve with the use of: 

  • AI/ML, more centralized approaches such as the  
    • Digital twin that encapsulates real world and synthetic data for both predictive analytics and maintenance.  
  • RF tech at high frequency 
  • Capacity, latency and performance 
  • Openness, disaggregation
  • Environmental footprint 
  • Productivity and speed to market 
  • Economics and cost 

And as a backdrop to this more and more moving to the edge and the cloud which will require new test architectures and new tools.   New use cases (yet to be defined, of course) will need to be emulated to ensure networks can support both these and those running on legacy standards. And if operators thought 5G networks were complex…

6G promises leaps in efficiency and extended capability, but to make these promises a reality, testing begins at the design phase.
