Cloud-based Cellular Network in a Browser
While several open-source cellular network implementations have emerged over the past decade, most remain complex and inaccessible to non-experts—limiting broader exploration and innovation in the field.
This project aims to change that by introducing a browser-based cellular network powered by WebUSB and WebAssembly. By connecting a USB software-defined radio (SDR), users can deploy cellular networks without requiring deep engineering knowledge or complex setups.
The WebSDR architecture runs a full BTS (Base Transceiver Station) directly in the browser, while BSC/MSC components operate in the backend - either locally or in the cloud. This allows rapid, plug-and-play deployment of 2G networks for a wide range of use cases, including emergency response, off-grid expeditions, temporary installations, and prototyping.
By making cellular technology more accessible, the project fosters openness, hands-on experimentation, and inclusive innovation in wireless communications - establishing 2G as a practical starting point for building and understanding more advanced 4G and 5G networks.
