Spectrum and Regulatory Challenges Related to eVTOLS
Electric Vertical Take-Off and Landing (eVTOL) aircraft are poised to revolutionise urban mobility, with commercial operations expected to begin as early as 2025 and significant growth anticipated by the 2030s.
The successful integration of eVTOLs into airspace and transportation networks hinges on resolving complex spectrum and regulatory challenges. This paper by Coleago Consulting, in collaboration with Cranfield University, outlines the key issues that national telecom and aviation regulators must address to facilitate safe, efficient and scalable eVTOL operations.
Key Challenges Identified
Spectrum Availability and Management
- eVTOL systems require access to highly reliable, low-latency spectrum for communication, navigation and safety-critical functions
- There is currently no globally harmonised spectrum for eVTOLs, risking potential interference issues
- New spectrum zoning and licensing models are needed to address low-altitude, urban airspace operations
Regulatory Framework Gaps
- Most jurisdictions currently lack comprehensive eVTOL-specific regulatory frameworks
- Integration with existing services and avoidance of interference with terrestrial and aerospace systems is a major concern
- Certification and licensing must align with global aviation authorities like the FAA and EASA
Technology and Network Interoperability
- eVTOL platforms will require robust integration across 5G, satellite and aviation-specific networks
- Seamless multi-network handover, hardware standardisation and system resilience are critical for safety and scalability
Cybersecurity and Privacy Risks
- The reliance on networked communications introduces vulnerabilities to jamming, spoofing and unauthorised access
- Data protection and secure information exchange among stakeholders are essential
Stakeholder Coordination
- Effective cross-sector governance is needed to bridge regulatory silos across telecommunications, aviation and urban planning sectors
- Engagement with diverse stakeholders including operators, regulators and municipalities is vital for coherent policy development
Public Acceptance and Confidence
- Addressing concerns about noise, safety and visual impact is key to gaining public trust
- Transparent communication and community engagement will play a crucial role in acceptance
Conclusion
The development of a forward-looking, harmonised and adaptive regulatory environment is essential for unlocking the full potential of eVTOL technologies. Coordinated action among regulators, industry stakeholders and international bodies will be required to address the spectrum, safety and societal dimensions of this transformative transport mode. Coleago Consulting offers deep expertise in spectrum management and regulatory strategy to support stakeholders navigating these challenges.

The Case for Strategic Spectrum Renewal
As spectrum licences approach their expiry date, a strategic approach to spectrum renewal is crucial. Traditional presumption of renewal in favour of incumbents may no longer serve the industry’s needs. Instead, a more strategic approach to renewal can optimise spectrum assignments and improve spectral efficiency by up to 40%.
Best Practice Spectrum Management
The principles of best practice spectrum management are well established and their implementation can enhance the socio-economic value of spectrum and how much operators are prepared to pay to acquire new spectrum. Whilst most regulators in developed markets have adopted best practice, the same cannot be said for developing markets. Coleago recently studied the regulatory environments in 16 African markets and recorded the extent to which best practice had been adopted.
Learning From Best Practice Spectrum Management in Botswana
The Botswana Communications Regulatory Authority conducted a review of its spectrum management strategy to align with international best practice. The Authority was advised by Coleago and in this paper, Project Director Graham Friend highlights the lessons to be learned for other regulators in developing markets.
The End of Telecoms History? – Not Quite!
At the European 5G conference, Stefan Zehle highlighted that differences in mobile data usage across countries result from variations in price and network availability. While European policymakers celebrate 89% 5G coverage, gaps in both outdoor and indoor connectivity limit usage. William Webb’s prediction that data traffic will plateau at 20 GB per user per month by 2027 seems unlikely, given that top users already exceed 100 GB. To fully realise 5G’s potential, policymakers must address these coverage issues in a cost-effective manner.
