• 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.
