The ‘
full’ 5G System includes:
- eMBB (enhanced Mobile Broadband)
- URLLC (Ultra Reliable Low Latency Communications)
- mMTC (massive Machine Type Communications)
The initial phase of 5G Non-Standalone deployments focuses on eMBB, which provides greater data-bandwidth complemented by moderate latency improvements on both 5G NR and 4G LTE. This will help to develop today’s mobile broadband use cases such as emerging AR/VR media and applications, UltraHD or 360-degree streaming video and many more.
mMTC has been already developed as part of 3GPP Release 13/14 low power wide area (LPWA) technologies, which includes NB-IoT. These are expected to meet most 5G mMTC requirements, while others that require more bandwidth with ultra-reliable low latency (full URLLC) will require the 5G Core deployment for full end-2-end latency reduction.
Mission critical applications that are especially latency-sensitive will also require wide coverage, which is highly unlikely in early 5G deployments, so this development will come later.
