I would like to feedback aspects of what I am learning at the 5G conference in Durban.
5G trials are under way but that does not mean 5G is here. 5G will only be fully defined in 2020 receiving feedback from these trials.
There are 3 key elements to 5G
- Enhanced mobile broadband
- Massive machine type communications
- Ultra-reliable and low latency communications
5G networks will focus on one of the 3 elements and will vary between areas.
There is an emphasis globally that 5G needs to improve the digital divide rather than aggrevate it.
There will be a global spectrum decision at WRC-19 in Egypt in November 2019. After this, individual countries have the autonomy to assign spectrum to 5G.
The key industry driving 5G is the automotive industry. Automotive industry is dring the need for low latency.
Youtube "Korea 5G trials" for some great videos on what bandwidth will do with entertainment industry.
The key driver for 5G is the automotive industry. Google "5G and the automotive industry"
Connected cars are a reality now.
They provide solutions for:
- Congestion control
- Pollution reduction
- Liveability and safety
They need high bandwidth, low latency mobile connectivity.
Driverless cars are thought to become a reality on our roads by 2030.
Experiments already underway with connected trucks in convoy having significant reduction on fuel costs. I guess like bike racing.
Mobile phones will be set up such that they can receive high bandwidth on a higher frequency and transmit on a lower frequency that has further coverage.
3.5 GHz is a target spectrum for 5G
28 GHz is also a target spectrum for USA and Japan
Some mobile operators acorss the world are struggling with the business case for 5G. It is thought that they will have to share investment and networks in many countries.
