How Mobile Phones Work

Mobile phones have come a long way since their creation, especially in the last 20 years. From large, heavy, “brick” phones that made calls similar to using a walkie-talkie to small, slim computers that are now able to play music and browse the Internet like our desktop computers at home. Each year it seems that smartphone manufacturers find a way to come out with something faster, sleeker and more improved than the latest available model. With all of the smartphones on shelves today, it’s seemingly impossible to keep up with each piece of cutting-edge smartphone technology that’s at our fingertips. More importantly, however, even though we use our mobile phones every day, do we really know how they actually work?

Many people may look at a smartphone and understand that it needs to be battery powered to operate, that it needs to be powered on and within range of a cellular tower to have a signal to work, or that the smartphone needs to be connected to a WiFi or data network in order to access the internet. With each understanding, these people would be correct and, most of the time, further knowledge in order to operate a smartphone isn’t completely necessary. This holds especially true with each new and improved model smartphone being released with cell phone carriers and manufacturers always trying to design something easier to use. It isn’t very uncommon, in this day and age, to see children as young as 5 years old operating a cell phone without problems. Yet, whether 5 years old or 85 years old, it is most likely safe to assume that everyone has wondered how mobile phones work.

Fundamentals In How Mobile Phones Work

Each cellular phone contains a circuit board, antenna, LCD (Liquid Crystal Display), keyboard, microphone, speaker and battery. These components are connected and operated through the motherboard of the cell phone. These components all work together inside of your cell phone in order to make 2-way or group calls, browse the internet, check email, play games, take notes, keep a schedule and much more. Even security and privacy features such as fingerprint scanning and facial recognition or controlling the thermostat in your home is something that cell phones are capable of handling. Where high-tech or futuristic functions such as these were once only depicted in science fiction media, now have become regular features and practices in our cell phones and computers.
