How Does Mobile Phone Work

Cell phone in simple terms is a small hand-held electronic gadget usually used to find the owner's name, their address, phone number, email address and other relevant information. Often times called cell phones, they are now more popular than a phone placed on a desk top. A mobile phone can also act as an International dialling service, operating upon a pre-programmed or pre-determined signal and/or disambiguation code.

A subscriber information (also known as IM's) is what gives a user access to various services offered by their mobile network company. This includes accessing their phone book, finding local numbers, sending voice messages and faxes, playing ring tones, downloading ring tones, accessing maps, accessing family members' addresses book, listening to voice mail, calling background music, receiving text messages and so much more. The subscriber information is stored within the cell phone owner's profile on the wireless carrier's server and is then accessible by any authorized mobile device with SIM card installed.

Mobile phones generally use two types of base stations for communications; public access and cell towers. Public access towers are usually placed above roads and airports. Cell towers are usually placed in dense urban areas near large numbers of residential and business neighborhoods. They work by picking up signals from a group of cells linked together by fiber optic cables or radio frequencies. Both types of antennas have advantages over each other.

Public access towers are vulnerable to directional interference. This means if the transmission towers receive strong radio frequency signals from adjacent cell towers, it can interfere with the receiving device. There are some countries that prohibit the use of cell towers on airport grounds, mainly for safety reasons. However, this can be circumvented by using portable devices such as GPS (Global Positioning System) or lap top computers. Global Positioning System or GPS uses satellites to pinpoint an individual's location. Portable devices such as lap-top computers or GPS devices can pick up signals from these satellites and obtain the location of the cell tower.

Another major advantage is that cell phone towers operate in the digital form of electromagnetic waves. Unlike radio waves which are transmitted via electrical impulses, digital waves are transmitted via direct currents. This means that they can easily penetrate through objects like metal and natural fibers. Digital signals are also independent of various atmospheric conditions; they can work even in rain or fog.

Another major advantage of mobile phones is that they allow users to share videos, pictures and text with other people who are on the same network. This is because of the technology called GPRS (Global Positioning System). GPRS works using digital information lines (DSL or electricity lines) which carry digital information instead of voice signals. This means that every cell tower can help give a digital signal whenever necessary.

Mobile phones also allow users to browse the Internet using GPRS technology. It is this feature that helps cell phone users to access the web. Mobile phones dial into a digital network made up of radio waves called CDMA (Cellular Digital Subscriber Line) and TDMA (Temporary Digital Access Memories) using the same technology that is used to dial into a cellular network using your home phone. These radio waves are then converted into voice signals. This technology is used to send information back and forth between two communicating devices. When a user makes a call, it is this voice communication component that is picked up and sent to the receiving party.

The modern cell towers and their associated technologies are an amazing invention. They have made mobile communication a lot simpler for us. With the use of such things as mobile phones and their related equipment, it makes it a whole lot easier for individuals to stay connected and in contact with each other. However, the invention of the cellular towers has also made it easier for individuals to exploit these technologies for their own personal gain. In order to protect yourself against the many ways that electromagnetic waves are being used against you, it is important that you pay attention to the details of how mobile phone works.
