Network Slicing

a technique used in 5G networks to create multiple virtual networks (slices) on top of a shared physical infrastructure, each tailored to specific requirements

Radio Access Network (RAN)

the part of a mobile network responsible for connecting user devices to the core network through radio waves

Radio-Frequency Identification (RFID)

a technology that uses radio waves to identify and track objects embedded with RFID tags

Satellite Communication

wireless communication that relies on satellites orbiting Earth to relay signals between different locations

Small cell

a low-power cell site in a cellular network providing coverage over a small geographical area, typically used to enhance capacity in high-traffic zones

Streaming

a method of transmitting or receiving data, especially audio and video, over a computer network as a continuous flow, allowing playback to begin while the rest of the data is still being received

Virtual Private Network (VPN)

a technology that creates a secure, encrypted connection over a public network , such as the internet, to protect data transmission

Wide Area Network (WAN)

a network that connects computers and other devices over a large geographical area, such as a state, country, or the entire world
