With global mobile subscriptions, mobile phones have become a universal and indispensable tool for modern life. With a mobile phone, you can stay in touch with anyone on the planet from almost anywhere. So, what is this mobile phone all about?<\/p>

The abbreviation \u201cGSM\u201d stands for Global System for Mobile Communications. In its most basic form, a mobile phone is essentially a two-way radio, consisting of a radio transmitter and a radio receiver. When you make a call, your mobile phone converts your voice into an electrical signal, which is then sent via radio waves to the nearest mobile phone mast. The network of mobile phone masts then transmits the radio waves to your caller\u2019s mobile phone, which converts them into an electrical signal and back again to sound. In its basic form, a mobile phone works just like a walkie-talkie.<\/p>

Besides the basic function of voice calls, most modern mobiles are equipped with additional functions such as surfing the web, taking photos, playing games, sending text messages, and playing music. More advanced smartphones can perform similar functions to a portable computer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Mobile Phone Types<\/h2>

The first telephones used analog technology. This is pretty much how a homemade tin telephone on a wire works too. When you speak through a can, your voice makes the string vibrate up and down (so fast you can\u2019t see it). The vibrations go up and down like your voice. In other words, they are an analog of your voice \u2013 which is why we call it analog technology. Some landlines still work this way today.<\/p>

Mobile phones today work with digital technology: they change the sounds of your voice into a pattern of digits and then beam them through the air. The use of digital technology has many advantages. It means that mobile phones can be used to send and receive automated data. Therefore, most mobile phones can now send and receive text messages, web pages, music files, and digital photos.<\/p>

Digital technology means that telephone calls can be encrypted (encoded with a mathematical code) before they leave the sender\u2019s phone, so that no one can eavesdrop on them. (This was a big problem with earlier analog phones, which anyone could intercept with a miniature radio receiver). This makes digital phones much safer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Antenna<\/h2>

Mobile phones contain at least one radio antenna to transmit or receive radio signals. An antenna converts an electrical signal into a radio wave (transmitter) and vice versa (receiver). Some mobile phones use one antenna as the transmitter and receiver, while others, such as iPhones, have several transmitting or receiving antennas.<\/p>

An antenna is a metal element (such as copper) that is designed to have a specific size and shape for transmitting and receiving specific frequencies of radio waves. While older generation mobile phones have external or removable antennas, modern mobile phones contain more compact antennas inside the device thanks to advanced antenna technologies. It is important to understand that all metal components in the device (such as the circuit board and metal frame for the iPhone) can interact with the transmitting antenna(s) and contribute to the pattern of the transmitted signal.<\/p>

Many modern smartphones also contain more than one type of antenna. In addition to the mobile antenna, they can also have Wi-Fi, Bluetooth, and\/or GPS antennas.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Connectivity<\/h2>

As mentioned earlier, a mobile phone is a two-way wireless communication device and both the incoming signal and the outgoing signal must work. The size of the signal received from the mobile phone mast is called the \u201csignal strength.\u201d You can read the signal strength from the bars on your mobile phone. The connectivity between a mobile phone and its mobile network depends on both signals and is influenced by many factors, such as the distance between the phone and the nearest mobile tower, the number of obstructions between them, and the wireless technology. Poor reception (fewer bars) normally indicates a long distance and\/or a lot of signal interruption between the mobile phone and the mobile phone mast. These bars represent an abstract picture of the signal strength.<\/p>

To save battery life, a mobile phone will vary the strength of the transmitted signal and use only the minimum necessary to communicate with the nearest mobile phone mast. When your mobile phone has a bad connection, it sends out a stronger signal to connect to the tower, which drains your battery faster. So, a good connection not only means fewer dropped calls but also longer battery life.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
