Managing 5G Power

Demonstrating how cellular base station operators can securely manage the use of batteries and remote power feeds in 4G and 5G base stations using LSO APIs and Web3 including self-sovereign identity.

Project White Amber

4G and 5G base stations are considered critical infrastructure and require power supply at all times. Batteries are used in many base stations to ensure continuity of operation in the event of a break in power supply from the main grid. They are also used to store power from nearby renewable energy resources (e.g., wind turbines and solar panels) and to store power purchased from the grid at discounted rates (e.g., at night) for use during periods of high cost electricity supply.
Power distribution between central base stations and satellite stations using remote power feeds enables optimization of the positioning of batteries for access, maintenance and security. Large batteries can be stacked in a central location supplying power throughout a group of nearby base stations.
Battery technology is constantly improving, driven in large part by the rapid growth of the electric vehicle market that relies on new ~400VDC battery technologies to maximize the travel between recharges. This together with the fact that the ~400VDC power technology is also more efficient for remote power feeds 4G and 5G base stations means that there is an increasingly better understood opportunity to replace current 48VDC legacy batteries with electric vehicle batteries (EVBs) both new and refurbished as part of the shift to a circular economy.
Because EVBs need constant health monitoring during their lifetimes to protect against very rare cases of internal faults and resulting thermal runaway, they are connected to cloud services via their host vehicles. For such large scale monitoring of hundreds of millions of EVBs on the road, Web3 technologies are needed to provide each battery with a self-sovereign digital identity that is used throughout its lifetime. This digital identity holds proofs of details regarding its ‘birth’, its composition and specifications, its maintenance history, its host environment and finally its decommissioning or refurbishment for a new environment.
The technology developed by MOBI’s Citopia for EVB management in mobile environments can be repurposed for EVBs in the 4G and 5G base station environment. MEF LSO APIs can be used by cellular networks operators to ensure streamlined information transfer between stakeholders involved in the EVB’s lifecycle in the 4G and 5G environment. This, together with new remote power feed solutions can revolutionize the power infrastructure of cellular base stations and accelerate the transition to a more sustainable and scalable use of power in this ecosystem.
The White Amber project will develop key deliverables that can be used by cellular network operators to enhance their 4G/5G power infrastructure strategies.

What can be achieved as a result of this project?

Mobile operators will be able to use Web3 techniques for managing all aspects of the lifecycle of batteries in their 5G base stations including:

  • Identifying suitable battery suppliers
  • Receiving price quotes and issuing orders
  • Onboarding the batteries into the base station
  • Monitoring their health
  • Managing their maintenance
  • Reporting on their provenance for regulatory purposes
  • Decommissioning the batteries for recycling

Significance

The energy costs coupled with ensuring high resilience of mission critical 5G infrastructure makes the management of batteries and remote power feeds in base station environments a core component of wireless access strategy.

Inspiration

The work of MOBI with the vinTRAK application in Citopia for use in tracking electric vehicle batteries (EVB) in tens of millions of electric vehicles on the roads worldwide.

Near Future

Jan 2023 milestone: Launch of project in MEF Showcase
Apr 2023: Demo of use of Citopia and ITN (Integrated Trust Network) in the lifecycle of 5G base station battery
Jul 2023: Scaled up demo for multiple stakeholders

Action Needed

Addition of mobile operators to the project.

Without This Project

Mobile operators will face ever increasing costs around not meeting SLAs and the burden of manual administration.
