Intro The Spatial Web represents the next evolution of the internet, seamlessly connecting the digital and physical worlds. It leverages technologies such as IoT, 5G/6G networks, spatial computing, and built-in security to deliver personalized, immersive experiences. Unlike the traditional web, the Spatial Web connects not just information, but also physical spaces, devices, people, and AI agents through a common standard. Any device—whether it's a smartphone, sensor, headset, or autonomous vehicle—can instantly share data, knowledge, and capabilities. This Catalyst project utilizes Open Gateway APIs (via CAMARA) and TM Forum (TMF) APIs to develop a new, open communication protocol for the Spatial Web, supporting a wide range of spatial experiences. Through this protocol, Communication Service Providers (CSPs) can manage Spatial Web Nodes—essential components for spatial computing and positioning-based services—and offer them as a service. This innovative service model opens new revenue streams for CSPs, while aligning with Application Service Providers (ASPs) and Digital Service Providers (DSPs). The convergence of 5G, IoT, blockchain, and AI is shaping the Spatial Web, giving telecommunications companies new ways to enhance customer experiences and drive business growth. Development and Use of TMF and CAMARA APIs Open Gateway APIs network exposure is probably the biggest revenue opportunity for telecom market we have seen in the last years. STL Partners forecasts that the mobile network API revenue opportunity will reach US$34 billion by 2030. GSMA Open Gateway is a framework of common network Application Programmable Interfaces (APIs) designed to provide universal access to operator networks for developers. With the support of 72 mobile network operators, representing more than 78% of mobile connections in the world, GSMA Open Gateway builds the world’s largest connectivity platform, enabling application developers to deploy services on it. TMForum, Linux Foundation and GSMA are the SDOs collaborating in this program, being TMForum in charge of the Operate APIs definition, offering programmable access to Operation, Administration and Management (OAM) capabilities to facilitate the integration of the Operators with channel partners, marketplaces and other aggregator platforms. Working together with the Operate APIs group in the Open API program, this catalyst project is a real implementation of the Open Gateway Product Catalog API (TMF936) and the first implementation of a proposal for the Open Gateway Product Usage Management API (TMF937), enabling product catalog sharing and billing processes between operators and channel partners, building at the end of the day, key assets for the Open Gateway monetization. On the other hand, Spatial Web creates a new ecosystem of customer experiences and opportunies for developers. This catalyst proposes new revenue streams for telecom operators while enhancing the overall functionality of the Spatial Web through the network APIs. Spatial Web Demo The demo will showcase how operators can leverage the Spatial Web and Open APIs to unlock new business opportunities. It will highlight the use of various APIs, including population density data, location retrieval, device location, geofencing, carrier billing, and SIM swap. These capabilities enable operators to design targeted and efficient marketing strategies, enhance customer engagement, and optimize operational workflows. Visitors will be guided through a storytelling experience that demonstrates how Open Gateway and TMF APIs are used in the development of the Spatial Web.
