What is NTN?
NTN refers to a communication system that transmits data through non-terrestrial platforms, such as satellites, high-altitude platforms (HAPs), drones, or other aerial technologies, instead of relying on traditional terrestrial infrastructure like cell towers and cables.
The definition of Release 17, as outlined in 3GPP, includes enhancements to 5G New Radio (NR) to support NTNs. This signifies the first time a cellular network integrates satellite communications into its framework.
Why are satellites part of 5G standards?
There are several reasons to integrate satellite links into the 5G standards, and the answer is in 3 Words: Independence, Mobility, and Availability.
- Independence from terrestrial infrastructure
- Satellite communications enable mobile network operators (MNOs) to provide 5G services in areas lacking terrestrial infrastructure.
- Service availability during disruptions
- MNOs can maintain service when terrestrial networks become unavailable, for instance, during natural disasters.
- Extended service to moving platforms
- Satellite communications can deliver 5G service to various moving platforms, such as aircraft, ships, and trains, particularly in remote areas where building a terrestrial network is not feasible.
