A landline phone does not need Wi-Fi, mobile data, or towers.
It runs on copper wire electrical signaling.
• Voice signals
• Dialing tones
• Ringing voltage
• Even backup power
When you speak, your voice vibrates a small diaphragm inside the handset.
These vibrations change the electrical current flowing through the copper wires.
The telephone exchange receives these electrical variations and routes them to the receiver’s line, where they are converted back into sound.
• Landlines work during blackouts
• Emergency services still rely on them
• No internet is required
Your voice becomes electricity.
Electricity becomes voice.
