## Summary

Ofcom, the UK’s communications regulator, has completed a contracting process to update its height-based clutter dataset used in radio wave propagation models. The contract was awarded to Bluesky International Limited, and the procurement method employed was 'limited', indicating below-threshold competition. The tender falls under the 'services' category with a focus on data services, and it involves services to be delivered within the United Kingdom. The contract commenced on 9th February 2026 and will conclude on 8th June 2026, with an award value of GBP 49,026. This project, which aims to improve the prediction accuracy of radio wave propagation, highlights Ofcom's focus on advancing its technical spectrum management framework.

This tender presents business growth opportunities primarily for small to medium enterprises specialising in data services, particularly those experienced with geographic and technical data classifications. Companies like Bluesky International Limited, a seasoned supplier in the field, can leverage their expertise to meet Ofcom’s specifications for a height-based clutter classification methodology. This contract underlines a niche market niche that regulatory bodies like Ofcom are targeting, offering smaller and specialised firms a pathway to engage with government projects and expand their portfolio in public sector services.

## Notice

Ofcom has a requirement to update the "clutter" dataset used by the radio wave propagation models in our technical spectrum management framework. Our recent work concludes that transitioning to more granular and height-based clutter classification significantly improves prediction accuracy. We have developed a methodology for generating height-based clutter classification and would like the delivery of this product based on our specifications.
