After the communication revolution in the nineties, mobile phones are no longer just a source of communication and information but have become an important means of entertainment. Today everyone is crazy about mobile. Mobile is the need of someone and fashion for someone. Many people use it only for communication and many are getting many modern facilities from it.
Once mobile was used only by rich people but now due to its low price and many features, common people have started using it. Earlier the user had to pay for both incoming and outgoing, but now due to the incoming free, its scope is getting wider.
The biggest advantage of a mobile phone is that it does not have to be 'fixed' in one place. This is a cordless or wireless phone. No wires etc. are used to connect it. That is why it can be used while traveling or while traveling while sitting in your car. Using this, the mobile holder located in any corner of the world can be talked to.
A small ray of mobile has become a big wave. Today's young generation is desperate to get every facility that a computer gets from a mobile. This is the reason why mobile service companies are trying to provide it with all the facilities of a laptop computer. mobile s. M. s. (Short Message Service) facility has led to tremendous growth in the customer base. While mobile phones have fulfilled the dream of keeping the world in their grasp by connecting to the Internet, on the other hand its misuse has created many problems. Today's youth is flouting the rules of decency and giving rise to some unique crimes. Let's know technical information about mobile:
Mobile phone works through radio waves. It uses high frequency waves. First of all, the area in which the service is to be provided is divided into smaller parts. Such geographical parts are called 'cells'. This is the reason why sometimes mobile phones are also called cell phones. Each cell is equipped with a transmitter (Wave transmitter) and a receiver (Wave receiver) installed by the service company. Mobile Switching Center in the cell i.e. M.S. C. (MSc) are also established. Each cell has a limited proliferation area or range. A special provision has been made in the mobile system. In which after the range of transmitter of one cell is over, your mobile gets connected to the transmitter of the next cell in the blink of an eye. It's all M.S. C. It is through technology. It takes so little time for a mobile phone to connect from one cell to another that the talker does not even know when he has left the 'range' of the first cell and is in the 'range' of the second.
Mobile signals are connected to communication satellites through a tall transmitting tower. When you want to make a call somewhere far away, your phone's signal reaches the satellite via the local transmitter and then the mobile's high power transmitter. These satellites receive mobile radio signals emitted from the earth. The electronic equipment and circuits in the satellite power it up and return it to Earth via a transmitter. The signal sent by the satellite reaches the receiver of the concerned cell through a high power receiver. In addition, this signal is released into space via the cell's transmitter at a specific frequency. This signal is received by the mobile phone with which the frequency of the signal is 'matched'. On the other hand, suppose different mobile phones are assigned a specific radio frequency.
When the frequency of the signal emitted by the transmitter matches that of the mobile phone, the receiver of the mobile is successful in capturing the signal. Thus we can say that a mobile phone can only receive a signal with a specific type of frequency. Meanwhile, it rejects the received signals with different frequencies. Thus we see that the mobile system works with the interplay of mobile switching centres, transmitters, receivers and communication satellites.
Modern facilities are being filled in the new generation mobile. Researchers have created several promising technologies. There are some similar technologies- G. s. M. and C. D. M. a. G mobile is used in S. M.(GSM) and C.D. M. a. (CDMA) third generation
It is considered beneficial for data services. Yes.
s. M. The full name of the Global System for Mobile & C. D. M. a. The full form of Code Division Multiple Access is. These attractive technologies include Airtel, Tata Indicom, Hutch, M.T. N. L., Reliance and India Mobile. Yes. s. M. The technology uses a narrow band with a frequency of 30 kHz and a length of 6.7 milliseconds. On the other hand D. M. a. It is being used to digitize the data. C. D. M. a. Technology equipped mobile s. Tea. D. And me. s. D. Calls are becoming much cheaper than land line phones. C. D. Thanks to MA technology, digital data can be exchanged at speeds of up to 140 gigabytes per second. On the other hand, computers connected to telephone lines via modems can only operate at a speed of 56 kilobits per second. Thanks to this technology, computer work can be done from a small phone. Such advanced technology Presently it is being done only in developed countries like Japan, America.
According to top Reliance officials, an optical fiber network of 60 thousand kilometers has been laid to make such technology faster across the country. Thousands of communication transmitters are connected to this communication network which are mounted on high towers. This high-speed computer-driven web is integrated with mobile services using specialized software. With its use, the customer can take the work of a palm-top computer from a mobile at a very low cost.
