This article details how to configure a Raspberry Pi as a weak network simulation gateway, enabling developers to emulate 2G, high latency, and packet loss environments. By using tools like tc (traffic control) and netem, you can create controlled network impairments to test how your applications behave under real-world poor connectivity. This is crucial for mobile apps, IoT devices, and any software that must function reliably in areas with limited infrastructure. The guide covers setup, configuration, and practical testing scenarios, making it a valuable resource for ensuring app robustness without expensive hardware.
