How is a phone operated?
Cell phones use radio waves to communicate. Radio waves transport digitized voice or data in the form of oscillating electric and magnetic fields, called the electromagnetic field (EMF). The rate of oscillation is called frequency. Radio waves carry the information and travel in air at the speed of light.
How stuff works inside a cell phone?
Inside a digital cell phone, youll find a circuit board, battery, speaker and more. The circuit board is the heart of the system. The analog-to-digital and digital-to-analog conversion chips translate the outgoing audio signal from analog to digital and the incoming signal from digital back to analog.
How does cellular technology work?
The concept goes beyond the number of antennas and deals with how the radio frequency itself is used and reused. 1. Each cell has its own antenna and low power Base Station to handle the traffic within it’s area. 2.
Do cell phones use radio waves or microwaves?
Cell phones send signals to (and receive them from) nearby cell towers (base stations) using RF waves. This is a form of energy in the electromagnetic spectrum that falls between FM radio waves and microwaves. Like FM radio waves, microwaves, visible light, and heat, RF waves are a form of non-ionizing radiation.
Which mobile operating system works with the phone?
1. Android OS (Google Inc.) The Android mobile operating system is Google’s open and free software stack that includes an operating system, middleware and also key applications for use on mobile devices, including smartphones.
What is mobile operating system give examples?

What part of the phone is the receiver?
handset
Receiver. The receiver is located in the earpiece of the telephone’s handset. Operating on electromagnetic principles that were known in Bell’s day, it converts fluctuating electric current into sound waves that reproduce human speech.
What goes into making a phone?
A cellphone is made from a variety of metals, with the most common being aluminum alloys, lightweight materials commonly found in the phone case. Lithium cobalt oxide and carbon graphite are used to make the batteries. Elements like gold, copper and silver are used in the wiring of the phone.
What technology do mobile phones use?
Digital cell phones use the same radio technology as analog phones, but they use it in a different way. Analog systems do not fully utilize the signal between the phone and the cellular network — analog signals cannot be compressed and manipulated as easily as a true digital signal.
What is cellular communication technology?
Cellular communication is a form of communication technology that enables the use of mobile phones. A mobile phone is a bidirectional radio that enables simultaneous transmission and reception. Cellular communication is based on the geographic division of the communication coverage area into cells, and within cells.
How do microwaves work in phones?
A cell phone encodes the sounds of the caller’s voice in microwaves by changing the frequency of the waves. The encoded microwaves then travel through the air to a cell tower and eventually to the receiver of the person being called. The receiver decodes the microwaves and changes them back to sounds.
Is WIFI microwave or radio wave?
Wi-Fi transmits data using microwaves, which are high-energy radio waves. Wi-Fi is more complicated than FM radio, but the basic underlying technology is the same. They both encode information into radio waves, which are received and decoded. FM radio does this for sound, Wi-Fi does this for computer data.
What kind of gadgets can I use with my Smartphone?
From phone book and calendar to clock, camera, and music player, smartphones incorporate hundreds of little gadgets into one hand-held device. But, if you want to get even more out of your smartphones there are many accessories that can take your smartphone use to the next level.
What can you do with a cell phone?
After all, most people use the smartphone to browse social networks, listen to music, play games, make memes and upload photos to Instagram. Not much advanced intelligence needed to run those things. However the smartphone is essentially a small computer. You can do pretty amazing things with it including launch it into space as a nanosatellite.
How does a cell phone work and how does it work?
A cellphone handset contains a radio transmitter, for sending radio signals onward from the phone, and a radio receiver, for receiving incoming signals from other phones. The radio transmitter and receiver are not very high-powered, which means cellphones cannot send signals very far.
What can I add to my smart phone?
As smart phones become even more integral to our everyday lives, extra gadgets that increase their functionality just get cooler and cooler. These 15 add-ons for iPhone and Android handsets include arcade housings for gaming, home security devices, photo lenses, sound amplifiers and even wind meters.
