wireless signals
Broadcast through air
Wireless signals are electromagnetic waves that transmit information through the air without physical cables.
Radio, Wi-Fi, Bluetooth, and cellular networks all use wireless signals at different frequencies.
The term often appears in troubleshooting contexts: I'm not getting a wireless signal in the basement.
Signal strength depends on distance, obstacles, and interference from other devices.
