PROTOCOLS: 3G/4G• 3G/4G is a type of mobile tech giving you internet when

your Wi-Fi isn’t working. • 3G is slower than 4G because 3G offers download

• 4G is a mobile communications standard intended to replace 3G, allowing wireless Internet access at a much higher speed.

PROTOCOLS: BLUETOOTH• Bluetooth is wireless technology that is used to

send data over short distances.• A standard for the short-range wireless

interconnection of mobile phones, computers, and other electronic devices.

• In 1994 a group of engineers at Ericsson, a Swedish company, invented a wireless communication technology, later called Bluetooth
