Introducing OpenCellular: An open source wireless access platform

What this post added

This post introduces OpenCellular, an open-source, cost-effective, software-defined wireless access platform designed to improve connectivity in remote areas. It details the platform's modular design, supporting 2G to LTE and Wi-Fi, and its two main subsystems: General-Baseband Computing (GBC) with integrated power and housekeeping, and a Radio Frequency (RF) subsystem with an integrated analog front-end, supporting software-defined radio (SDR) or system-on-chip (SoC) options. The post also describes the exterior industrial and mechanical design for rugged environments and the software elements based on an open-source, real-time operating system. Testing in labs has confirmed SMS, voice calls, and basic data connectivity with a 2G implementation. The platform is intended to be open-sourced, fostering community development and deployment.
