What is 5G and how 5G will change your smartphones and your life.
5G stands for “Fifth Generation” which is the latest generation of cellular mobile communication? The most remarkable feature of the 5G network is its high speed and low latency. 5G can achieve up-to 10Gb/second data rates, which is 100 times faster than current 4G networks.
For example, it takes about 6 minutes to download 2 hours film using 4g. But with 5G the waiting time can be shortened to only 3.6 seconds.
The secret behind the 5G’s high speed is higher frequency radio waves. 5G utilizes “millimeter waves” which has an extremely high frequency from 30 to 300 Gigahertz. The high-frequency waves can provide wider bandwidths to make our network faster. Just like cars on the roads, 4 line expressway has a bigger maximum traffic flow than a single lane road.
However, the powerful millimeter wave has a weakness – low penetration ability, which leads to low coverage. A mass amount of base stations could solve this problem, but it will cost a lot and make the city more crowded. Luckily, “Nano base stations” can help to save cost, and make the networks more stable for users.
Think of it as a cold room with heaters. One high power heater can warm people around it, but those who stay a bit far from it are still cold. However everyone will happy if there are multiple low power heaters deployed across the room. 5G can do much more than making your internet faster, Not only can it provide better experience to AR and VR products, the low latency 5G can also bring autonomous vehicles out of the lab, make smart home smarter and provide more possibilities to AI.
China has been putting efforts in 5G development. The country is expected to start the pre-commercial use of 5G, mostly on smart phones, in the second half of 2019. And three major telecom operators of china plan to launch commercial 5G service in 2020, and some 5G applications of internet of vehicles will be realized in the same year.
