Since 1983, when telephone and radio technologies were combined, cellular telephony has ceased to be a luxury exclusive to the wealthy. Cell Phones become an accessory that fulfills basic communication functions.

Why Are They Called Cell Phones?

Wireless phone systems are divided into cells, which is why cell phone devices are called cell phones.

What Is a Cell Phone?

They are mobile and wireless devices with a digital system, basically they are radio transmitters that can constantly change channels and connect to different bases. They are classified as dual devices because they use one frequency to talk and another to listen.

How Do Cell Phones Work?

When you make a phone call, your cell phone emits waves that travel through the air and are received as electromagnetic signals. The electromagnetic signals are converted by satellite antennas to be received as intelligible sound. All of this is made possible by a combination of networks of radio receiving and transmitting stations and telephone exchanges.

Digital systems use base stations arranged in small cells and connected to form a network. Each station is located in the center and receives a certain number of transmissions from its network.

When a cell phone makes a cell, the base station transfers ownership to the cell that receives the strongest signal, which is the cell where the phone is located. Therefore, each city needs at least one central office to manage all the phone lines and stations in the area.

Digital systems use small cells, which, because of their size, make it impossible for every neighboring system to use the same set of frequencies. In this system, capacity is greater because there are many cells that reuse transmission frequencies that are nearby but not adjacent. Also, because of the small size of each cell, less power is required, reducing the coverage area, so smaller and cheaper devices are needed.
