Cell phones are also referred to as Handheld telephones. A cell phone, cell, hand phone or just cell, phone can make and receive phone calls on a standard radio frequency signal while the user is traveling in a phone service area while moving within a specific range of other cell phones. The cell phones also have different features such as call waiting, voice mail, clock, ringtone, USB device, web camera, video camera, Bluetooth, Wi-Fi, and Internet access along with the main phone. The main function of the cell phones is to make and receive phone calls. Most cell phones use the GSM (Global System for Mobile Communications) network technology. Some cell phones also use CDMA (Codependent Markup Language) technology.
How does a cell phone work? The main components are the microprocessor, the battery, the antenna and the micro circuitry that allow the cell phones to send and receive the radio signal. The microprocessor controls the software program that is installed in the cell phones. When the software is executed, it searches for a compatible signal and converts the analog signal into digital data. This is how a cell phone works.
Are there separate circuits for the LCD screen or antenna? Yes, there are. Most cell phones have separate circuits for the LCD screen and the antenna. This helps to ensure that there will be no interference from other signals or microwaves. However, some phones have built-in antennas that can be adjusted depending on the location. In most cases, separate circuits are required to cover the different locations of the base stations.
How are the signals transmitted? The process is very simple and the technology used is based on the principle of the radar gun, which uses radio waves to detect moving objects. Since the radio waves do not travel through liquids or gases, the process is very effective in detecting moving objects.
How is the data sent from the cell phones to the base station? The process is very simple. The user presses the send or dial command key to send a voice message to the other cell phones. The first cell phone receives the message and then the other cell phones in a series. This process continues until all cell phones are responding to a call or a request. The user then presses the send or dial command again to send a verbal reply to the other cell phones.
