Radio waves transport the information and travel in air at the speed of light.
An antenna helps us to transmit and receive frequencies of radio waves, but in some older generation phones, some antennas were external or extractable. Due to the blooming of technology, modern phones have compactable antennas inside them.
A large city has hundreds of towers. Each carrier in each city runs a central office also known as the Mobile Telephone Switching Office (MTSO).
It is important for the MTSO to know the cell phone one is using when the phone cell phone is about to ring.
When your phone and the tower switch on those frequencies you are connected and talking.
There are reasons to think that cell phones may cause cancer of the ear or brain tumors.
The more an individual uses cell phones and the greater the number of years used by the person, the greater the risk of brain tumors.
