Provide an interface for users to communicate with one another
Manage the transmission of data, instructions, and information
Network Communications Standards and Protocols
LTE (Long Term Evolution)
network standard that defines how high-speed cellular transmissions use broadcast radio to transmit data for mobile communications
Bluetooth
a network protocol that defines how two Bluetooth devices use short-range radio waves to transmit data
Wi-Fi (Wireless Fidelity)
any network based on the 802.11standard that specifies how two wireless devices communicate over the air with each other
UWB (ultra-wideband)
a network standard that specifies how two UWB devices use short-range radio waves to communicate at high speeds with each other
TCP/IP
(Transmission Control Protocol/Internet Protocol)
a network protocol that defines how messages (data) are routed from one end of a network to another
IrDA
(Insurance Regulatory and Development Authority)
transmits data wirelessly via infrared (IR) light waves

standard specifies computers and devices on the network share or pass a special signal (token)
RFID (Radio Frequency Identification)
a protocol that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person
Ethernet
a network standard that specifies no central computer or device on the network (nodes) should control when data can be transmitted
NFC (Near Field Communication)
a protocol, based on RFID, that defines how a network uses close-range radio signals to communicate between two devices or objects equipped with NFC technology
