The application profiles for new mobile telecommunication networks are defined by the 3GPP and the ITU. For 5G technology there are 3 main categories in which it shall improve on the network services of previous generations. These are:
Enhanced mobile broadband (eMBB)
Ultra-reliable low latency communication (uRLLC)
Massive machine-type communication (mMTC)
To achieve each of these services, a variety of new technologies are being deployed. In the first step eMBB will help to augment peak data rates, spectral efficiency and area traffic capacity. Together with uRLLC latency and mobility interruption time will in a next step fall close to zero. Finally mMTC adds on to vastly improve connection density – finally achieving all requirements for full 5G, which follow the IMT-2020 standard.
These Key Services must not be confused with OTT (over the top) services like streaming portals or other apps for tablets or smartphones. Those use the infrastructure of mobile communication networks but are not inherently built into them.
