Countless new applications
• IoT communications remains the most popular target use case for 5G, with 59 percent.
• The next most popular use case is video.
Source: Gartner Dec 2018.
URLCC
• Ultra-Reliable and Low Latency Communications
• require more bandwidth with ultra-reliable low latency .
• require the 5G Core deployment for full end-2-end latency reduction.
• require wide coverage
mMTC
• mMTC has been already developed as part of 3GPP Release 13/14 low power wide area (LPWA) technologies.
• includes NB-IoT.
eMBB
• offering ultra-high speed
• Offering sufficient capacity in
the initial stage
• Provides greater data-
bandwidth complemented by
moderate latency
improvements on both 5G NR
and 4G LTE.
