Why do cordless phone stop working if you move too far from the base?

Cordless phones operate using radio frequency signals to communicate between the handset and the base station. When you move too far from the base, the signal strength diminishes, leading to a loss of connection. This distance limit, often referred to as the phone's range, can vary depending on the model and environmental factors, such as walls or interference from other electronic devices. Once you exceed this range, the handset can no longer maintain a stable link with the base, causing it to stop working properly.
