Port City Colombo is a newly created urban development in Sri Lanka designed to be one of the world’s leading smart cities. Realizing this depends on a thriving tech ecosystem, which has everything it needs to build the architecture to support state-of-the-art infrastructure. As the nation’s principal CSP, Sri Lanka Telecom is taking a leading role in ensuring the city can deploy cost-effective 5G use cases throughout. This Catalyst will support this objective by identifying commercial opportunities, consolidating strategic partnerships and supporting deployments, while also making contributions to TM Forum assets. A key part of the project depends on developing cost-effective business models, with templates for establishing viability that can be applied to various industry verticals within the urban development. Such models will be based around the Port City Colombo Special Economic Zone, which provides a range of attractive and competitive opportunities for businesses of strategic importance. This status is complemented by clear and contemporary regulations that aim to enhance business development. The project is a clear example of how the industry can play a leading role in shaping newly-created smart cities and areas with special economic status. Moreover, it will serve as a blueprint for these environments, demonstrating how multiple sectors can reap the benefits of 5G networks and the autonomous operations they facilitate.
