from a layman’s eye
From 1G to 2G, 3G, 4G, and 5G, we are moving from analog to digital, from hardware control to software control and software defined network, from human-to-human communication to support more on human-to-machine and machine-to-machine communication.
From 1G to 5G, we are moving from carrying analog audio to digital audio, to message, and to multimedia and to IOT and industrial network.
the main characteristic of 5G
— ultra high data rates (eMBB)
— low latency (URLLC)
— high network density (mMTC)
what is the technology behind?
—advanced network
— mmWave
— multi-RAT (radio access technology)
— advanced MIMO
— multiple access
— advanced D2D (device to device)
— small cell
what exactly is ‘advanced network’?
— flat & distributed network architecture
— distributed management (shortest data path without traversing core network)
— context-aware resource allocation
— popularity based content caching using CDN
possible application enabled with 5G
— VR
— vehicle to vehicle communication
— IOT
— HD CCTV
— etc
