Networks connect nearly every computer through direct internet links or local area networks using communication. Wireless networks have advantages over wired networks like reduced clutter and increased portability and mobility by allowing connection from fixed locations and on the move. However, wireless networks still have lower data transfer rates and increased risks of interference compared to wired networks. Modern cell phones integrate many wireless technologies for both local and wide area connectivity for voice, data and video including WiFi, Bluetooth, GPS and upcoming 4G and 5G networks.
