What are the signals that are transmitted to and from wireless electronic devices carried on?

Radiofrequency (RF) Signals:

RF signals are used in various wireless communication technologies, including:

Cellular networks: Mobile phones use RF signals to communicate with cell towers.

Wi-Fi (Wireless Fidelity): Wi-Fi devices, such as smartphones, laptops, and routers, use RF signals to connect to local wireless networks.

Bluetooth: Bluetooth-enabled devices, like headphones, speakers, and smartphones, use RF signals for short-range wireless connections.

Zigbee: Zigbee is a wireless communication protocol commonly used in smart home devices like smart lights, thermostats, and sensors.

NFC (Near Field Communication): NFC technology allows devices to exchange data over very short distances, often used for contactless payments and device pairing.

Infrared (IR) Signals:

Infrared signals are used for short-range communication between devices that have IR transmitters and receivers. TV remote controls are a common example of devices that use IR signals.

GPS Signals:

Global Positioning System (GPS) devices receive signals from multiple satellites to determine their precise location and provide navigation information. GPS signals are crucial for location-based services and navigation applications.
