Alternatively referred to as cordless, wireless is the ability to operate a device without any wires that may cause constricted movement.
Note: Although cordless devices require no wires, they do require some device to broadcast a signal; for example, a Bluetooth mouse requires a USB Bluetooth transceiver to send and receive signals from the mouse. Also, all wireless hardware devices require batteries for power.
Wireless networks, more commonly known as a Wi-Fi networks, utilize one of the IEEE 802.11 standards for wireless communication. Today, wireless routers that offer Wi-Fi have become common in most homes as a way for computers, smartphones, tablets, and other wireless devices to connect to the Internet.
Besides wireless networks in the home, there are a number of broadband wireless solutions such as EVDO, Satellite, WiMAX. Users with smartphones can also use their smartphone as a wireless hotspot and connect to that hotspot with their computer.

Smartphones and cell phones
Today's smartphones and cell phones use a number of wireless technologies to communicate with the cell towers, Wi-Fi, and other devices. To make phone calls the phones use a spectrum of radio waves that allow wireless communication between the phone and the cell tower, which relays the signal to other towers or locations.
Finally, when communicating with other devices (e.g., car, headset, or speakers) smartphones typically use Bluetooth.
