# Topic 1: 5G overview.
>### Sub-topic 1: 5G, AI, IoT.
**The 3 most important aspects:**
5G Service and use cases, IoT, and 5G network slicing.
**Summary:**
### A. Definition 5G, IoT, and AI.
5G is a single network support a wide variety of vertical services. It enables a new kind of network that is to connect virtually everyone and everything together including machines, object, and devices. This 5G network offer to deliver higher multi-Gbps peak data speeds, ultra-low latency, more reliability, massive network capacity, increase availability, etc. 5G also will dynamically support multiple different services concurrently. IoT is a general term for a wide variety of vertical services. IoT is AI is a technique adopted to deal with complicated system.
### B. 5G service and use cases.
Switching from communication-oriented with 4G, 5G is designed to be service-oriented. This changing is also switching from one size fit all with multiple logic networks and bottom-up with top-down. 5G is being used in enhanced mobile broadband, mission-critical communications and massive IoT. Three main of use cases 5G is extreme mobile broadband (eMBB), ultra-reliable low latency service (uRLLC), and massive scale communication (mMTC). The main use cases is connecting human to human, human to machine, and machine to machine for its application.
### C. Difference between D-RAN,C-RAN, and V-RAN.

### D. M2M to IoT.
The efficiency from M2M to Internet of Things or IoT is evolve during this latest technology. This IoT also bring value to industry verticals. It’s not only about technology that bring efficiency and value to industry, but a way of trying the people and industry to achieve substantial value.
## E. Network slicing
5G network giving ability to all mobile service via all types of devices across all industry. Network slicing is operator who decide best answer on how to build and manage a network from a wide range of users. Achieving this sliced network is to transform it into a set of logical networks on top of a shared infrastructure. Each logical network is designed to serve a defined business purpose and comprises of network resource requirement, configured, and connected end-to-end.
Comment:
- 5G is a promising network to have a better lifestyle and industry. This 5G network need a great infrastructure to build. As long as infrastructure not capable to complete this network requirement then this network cannot be achieved. This 5G network that using network slicing will be more efficient and value industry verticals. This network will offer a smart city, smart monitoring wearable health measurement, smart home, autonomous vehicle, smart industry, etc.
