Science has made the distant near and the other its own.Science and all the wonderful discoveries have thus filled human life with happiness and comfort.Mobile phones are a new addition to people's happiness and comfort. Through mobile phones, people are reassured by the peace of their loved ones far and wide.As mobile has conquered distances, it has created uninterrupted bonds in communication.

Scientist Alexander Graham Bell was the first to be able to communicate with people far away. According to Alexander and Marconi, car radio radios were introduced in Detroit police cars. 1975 Car telephones are introduced in Stockholm.The size of the suitcase was divided into three parts.In the generation of mobile phones, the voice quality was very low and the security system was also low.The second generation has the advantage of accessing some data and words. The convenience of choosing a variety of subscriber services. In the third generation, mobile has a higher advantage.Internet, multimedia, global roaming facilities and mobile connectivity. Now added to the fourth generation, it has increased the speed of the Internet, the speed of information or multimedia exchange has increased.

Under a mobile phone system, a city is divided into smaller cells. Resulting in frequent reuse of frequencies within the city.And as a result, millions of people in the same city at the same time can talk on the phone.These cells can usually be 10 square miles. A cell is usually thought of as a hexagon part of a large hexagon grid.Each cell will have a relay station so that both cell phones and relays, including radio equipment from a tower and a small building, exchange signals at low power. Each city is controlled by a central office called the Mobile Telephone Switching Office.

Mobile phone use in Bangladesh has improved dramatically.A large portion of the total population is now using mobile.At present, six government and private mobile companies are providing services in Bangladesh.The number of mobile phone users is around thirteen crore.

A mobile phone is basically a two-way transmitter that can receive and transmit information.When a mobile phone wants to send a piece of information, it picks up a nearby station via the web and releases it at a certain level.The frequency of mobile that is currently being used in our country is 800 or 900 MHz.Grameen, Actel, Robi, Banglalink are currently using these three 900 MHz and Citycell 600 MHz.The more frequencies are used, the more radiation there is.However, the radiation level also depends on the price of the set.Radiation levels in expensive sets are relatively low.

Mobile phones seem to have captured the earth in a tiny set. With the help of mobile phones, modern busy people can communicate with people from far and wide at any moment.The advantage of a mobile phone is that it can be carried with you.

While the mobile communication system is cheap, easy and saves time and money, it also has some disadvantages.Subversive activities are easily carried out by organized gangs through mobiles. Mobile is used as an aid in anti-social activities like theft, robbery, snatching etc.Due to the mobile network, the miscreants were used by the members of the law enforcement agencies after receiving advance notice.After receiving advance notice due to the mobile network, the miscreants escaped by evading the eyes of the members of the law enforcement agencies.The perpetrators have been threatening the minds of some people through mobile phones.Mobile school, college and university students have many disruptions in their studies. Radiation or radiation from mobile phones harms the human body.
