A wireless network is a method of transferring data between two devices, one of which is a computer and the other is a mobile device, such as a mobile phone. A wireless network uses radio waves to transfer data. The data transfer uses the same radio waves that are used for television, GPS, and Bluetooth. In a wireless network, the data transfer is faster than in a cable network and it is more secure, because there is no physical connection between the devices.
