5G is the fifth generation wireless technology for digital cellular networks that began wide deployment in 2019. As with previous standards, the covered areas are divided into regions called "cells", serviced by individual antennas. |
1. Aspect of 5G
People says 5G provides wider bandwidth with high speed internet that we haven't experienced so far. It has great potential in terms of usecase's point of view.
One of the areas in 5G will be Immersive Multimedia Experience on broadcast, education, operation and etc. Below captured image shows the example:

I assume there will be many players who wants to take a leadership on certain area of services based on 5G internet ecosystem - it will be not only network operators, but also service providers as well.

2.2. Massive Machine Type Communications (mMTC)
Originally comes from 3GPP
...
. Following features are supported by 5G mMTC use case.
- mMTC stands for massive Machine Type Communications.
- It supports high density of devices (about 2 x 105 in 106/Km2)
- It supports long range.
- It supports low data rate ( about 1 to 100 Kbps).
- It leverages benefits of ultra low cost of M2M.
- It offers 10 years battery life.
- It provides asynchronous access.
There are more standards like eMBB, uRLLC like below, you can see more about uRLLC below.

uRLLC)
...
Following features are supported by 5G URLLC use case.
- uRLLC stands for Ultra Reliability and Low Latency Communications.
- It provides ultra responsive connections.
- It offers less than 1 ms air interface latency.
- It offers 5 ms end to end latency between UE (i.e. mobile) and 5G eNB (i.e. base station).
- It is ultra-reliable and available 99.9999% of the time.
- It provides low to medium data rates (about 50 kbps to 10 Mbps).
- It offers high speed mobility.
2.4. Evolved MBMS(Multmedia Broadcast Multicast Service)
e-MBMS is an extension of the 4G LTE system
...
. Operator can decide to allocate a part of the bandwidth available in downlink in a cell (up to 60%) to broadcast traffic that will serve multiple devices with the same content: video, audio, files, etc.
Content delivery is based on MPEG-DASH adaptive streaming but with a single representation or quality level per content.
