What is Wireless Technology and its Generation?

Welcome back to my blog, Seawolves! 

Long time no see:) 

Do you remember that we've discussed AI technology and Chat-GPT? It was interesting to get to know its creation, generation, and pervasive adoption in our society. When I started my first blog posting, I planned to focus on AI's misuse, particularly in education; at the same time, it would also be significant to talk about 5G which became the most fundamental/ultimate technology leading us to modern society. 

So today I will explain wireless technology, its generation from 1G to 6G, and its examples such as Tesla's Autonomous driving car. 

Okay. Let's deep-dive into wireless technology. First, my question is "What is Wireless?"

Cambridge Dictionary defined wireless as above. Our smartphones, AirPods, laptops, etc all include wireless characteristics, and it is one of the technologies to grant us a better convenient world. And when we talked about it, we could not forget to talk about 5G. There is a very strong connection :) 

5G basically indicates "Technology that gives mobile phone and internet users more advanced features than 4G. 5G is short for the fifth generation"(Cambridge Dictionary)

How about its generation from 1G to 5G?

Let's examine its beginnings: 1G and 2G. 

Do you remember analog voice transmission and bulky mobile phones? They are included in the first cellular generation (1G). For 2G, there was a more developed version of digital voice transmission and short message service (SMS).  

3G is capable of transmitting data and communication between machines; furthermore, 4G, as its enhanced version, can bring high-quality audio and video to smartphones. 

And 5G adopts a more sophisticated format than 4G and can deliver video/audio to many machines. Its special high downloading speeds, expanded capacity, and low latency brought a revolution in our technology society. AI and VR also came from 5G. 

5G's own characteristics are outstanding! It also positively impacts different sections: smart cities, health care, transportation, and retail. 

By the way, I want to introduce an autonomous driving car that relies on 5G's low latency. 

It is " a vehicle capable of sensing its environment and operating without human involvement". Tesla, which Elon Mush co-founded and leads, launched an autonomous driving car named "AUTOPILOT"

The company defines it as "an advanced driver assistance system that enhances safety and convenience behind the wheel" Its full self-driving and traffic-aware cruise control are astounding!

I consider that 5G is great for enhanced connectivity, innovation opportunities, and faster speed. At the same time, it leads to coverage limitation and security issues. We also need to consider its causing problems: the digital divide and privacy/data protection. Particularly, an autonomous car is generally hard to utilize in developing countries with crowded roads without structures, which can cause numerous accidents. It is the time to clarify its disadvantages and impacts on the world and compensate for possible risks.
