Development of the generation of the communication

  We are using smartphones daily but without the internet did we use? Of course "no". So here we go to know about the improvement of the communication

1G or 1st generation

If I want to tell you what is 1g? It is just the only voice communication. It is the 1st generation of wireless communication. now we are going to see how it's works- First, there are many cells are presented each cell covers a small area. It is analogue signal communication so it can only cover a small area. usage of many cells made a great spectrum. if we use many mobiles at same there may be an interruption for that there is a called a channel. Each channel is divided for each spectrum. so there is no interruption. The channels system are AMPS(Advanced Mobile Phone Service), TACS (Total Access Communication System) is used. These are controlled by the base station. The speed of the 1g is 2.4kbps. but there is no security for the data in 1g.

2G or 2nd generation:

2G or 2nd generation which used the digital radio signal first time for the communication. It works by TDMA (Time Division Multiple Access), CDMA(Code Division Multiple Access). It makes more people connect in the same cells compared to 1g. It gives access to SMS and internet.

3G or 3rd generation

3g or 3rd generation is an improved version of 2g.because after 2g came many people are starting to use mobile phones. after the introduction of the 3g, smartphones were coming. 3g is also known as"mobile broadband". The MSC(Mobile Switching Center)have the information about your plan, location etc, The cell tower gives the signal to the mobile phone. It works based on WDM (Wideband Division Multiple). The internet speed is 2 Mbps. It is done by HSPA+ (High-Speed Pocket Access) it uses long wavelength to provide the signal to the mobile phones. but the disadvantage is if there is any physical object is present between the tower and the Mobile phone.

4G or 4th generation:

4g or 4th generation is an upgraded version of 3g. The difference is just the internet speed. The speed was increased by the increase the strength of absorption of the signal by the antenna in the mobile phone. It is 3to 4 time stronger than 3g. So it uses MIMO(Multiple inputs Multiple Output)and OFDM (Orthogonal Frequency Division Multiple). After 4g, 4g+or the LTE ( Long Term Evolution) version. It was 2 times speed of 4g.

5g or 5th generation

5g or 5th generation differs from the 3g or 4g. 3g,4g use long-wavelength to sent signal, but 5g is inverse to this the 5g uses small wavelength to provide internet. There is good as well as bad. The good the speed will be in Gbps and the bad is the wavelength is small so it can't cover a large area like 3g or 4g. In the world many countries are testing for 5g at while there are many 5g phones are released.
We are thinking 1g,2g,3g,4g,5g is only present no there is 0g also I will speak about it in future.

Do you know?

#There are more than 40 mobile phones company like Samsung, oppo,vivo, Micromax,etc,. #In India the Nokia was the first phone that used.

How internet works part 2

Image
 Hey, everyone, it is the second part of how the internet works?. Until last, we saw only about how the internet works when we search directly the domain in search engine. In this, we are going to see how the search engine works when we search normally. What is search engine   The search engine is not a big thing it is a domain on the internet now apps also there. For example google, opera, duck 3duck go, Yahoo, etc. It gives the results when we search on the internet. How does the search engine work?    First, we want to search for anything in the search engine. For example: what is the radius of mars? For this, the search engine starts to search many pages to find the answers. But there the big problem starts. How does the search engine show results in seconds but there are billions of websites and it has many numbers of posts are there on the internet? How search engine find correct pages within seconds?  For that, a bot is used namely spider. Yes, the bot is...

Evolution of mobile phones in hardware

Image
Most of us know the phones are starting wired and become wireless but in large size, as years passed the phones become mobile phones and the new features are coming in them we will see the evolution of it in hardware and comment down below what is our next topic is going to be but not about the software The first portable phone    In the 1980s there was a huge competition between companies to make portable phones but finally, it was invented by Motorola company but it is like a brick in size as well as in weight it is about 9 inches(23cm) and 2.5pounds(1.1kg) it is a portable phone so it wants to have a battery. It only works for 35 minutes but it is about 4000 USD, so it was only affordable by rich persons the model name is Dyna Tax 8000x. But after some years they release 9800x which was less weight about (350g) but in the same size, it also has a flip cover to protect the keyboard. Nokia 1011   It was the next revolution in mobile phones but it was double the weight of...
