Helping the energy sector to be more efficient, effecti...
Spectrum is the lifeblood of wireless technology. But it is a finite resource with ever-increasing demand. As new technologies emerge – from 5G networks to the Internet of Things and smart cities – the need for fair and efficient access to this valuable asset is intensifying. This challenge grows even more complex with the path to 6G underway. To navigate this, auctions have become the cornerstone of transparent and strategic spectrum allocation.
When the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR) set out to allocate radio spectrum in 2024, there was no room for error. With tens of millions of Euros on the line, the auction had to be flawless. To guarantee this level of precision, we leveraged our world-class expertise in mathematical verification and spectrum management to deliver independent quality assurance. Through rigorous testing and certification, we ensured that RTR's auction ran smoothly and transparently, securing fair access to this vital national resource.

Flawlessly implementing complex auction rules
The Challenge
To meet growing demand for advanced services like 5G, telecommunications operators rely on spectrum as the backbone for expanding network capacity. RTR plays a pivotal role in enabling this growth by managing the award of several spectrum blocks, including remaining licenses in the 3.6 GHz band from a previous auction and new high-capacity spectrum in the 26 GHz band. This complex task requires balancing technical priorities with market needs to ensure operators have the resources to scale their networks effectively.
Spectrum auctions are high-stakes events with major implications for national infrastructure and economic growth. Auctions generate millions of Euros in revenue, but more importantly, the spectrum they award supports the rollout of the latest wireless technology.
RTR adopted an Enhanced Simultaneous Multiple Round Ascending Auction (ESMRA), a multi-round format where bidders compete for packages of licences. This approach helps allocate multiple resources efficiently in complex economic settings. However, this sophisticated auction mechanism presents substantial verification challenges and consequences.
The underlying algorithms must flawlessly implement complex auction rules. Even minor software errors could distort bidding outcomes, undermine fair competition, reveal confidential information or trigger legal challenges, which might necessitate a costly and reputation-damaging re-run.
Only thorough independent assessment can provide the assurance needed for such a high-stakes event.
DELIVERING TRUST AND ASSURANCE
The Solution
RTR engaged Smith Institute to conduct independent verification of the auction software ahead of its use, as well as validation of results during the live auction itself.
Building on our extensive experience verifying spectrum auctions for regulators including Ofcom (UK) and the FCC (US), we developed a comprehensive approach to the two phases.
In verifying the auction software, we constructed a comprehensive test plan. This allowed us to test every permutation of the auction rules, from likely core cases to rarer but important edge cases. We executed tests through both automated and manual approaches, enabling us to run large volumes of auctions while simultaneously ensuring total testing coverage. This provided RTR with assurance that even if an unusual situation occurred, the integrity of the auction would remain unimpeachable.
During the live auction, we conducted real-time verification round by round to assure RTR that the auction was proceeding smoothly and fairly. We independently cross-checked the allocation and pricing outcomes calculated by the auction software, providing vital final certification that all rules had been followed correctly. This gave RTR complete confidence in the integrity of their spectrum allocation process.
Supporting growing wireless demand
The Result
Our comprehensive verification process ensured a robust and reliable auction for RTR. By proactively identifying potential software vulnerabilities early, we safeguarded the integrity of the auction and mitigated risks to fairness and accuracy. The result was a system that performed exactly as intended.
The auction was a success: it generated €24.7 million in revenue and enabled RTR to assign valuable national spectrum to mobile operators, supporting the provision of critical wireless services to meet growing data demands. Beyond the immediate financial outcome, our work helped safeguard Austria's wireless digital infrastructure development and regulatory reputation.
By combining deep mathematical understanding with practical knowledge of spectrum management, we enable regulators to confidently manage spectrum—the invisible foundation of our connected world.
