How Do Cell Phones Work?

As everyone knows, cell phones have dramatically changed the way we live and work. While no one knows exactly how many cell phones currently exist in the world, the best guess is that there are over 7 billion subscriptions. That the world’s approximate population.

Landlines are becoming fewer and further between, with over 90% of the phones in use being cell phones.

Cell Phones are Like Radio Telephones

Cell phones are basically radio telephones that route their calls through a network of cell phone towers linked to a main public telephone network.

While cell phones and landlines do the same thing, they work in a completely different way. Landlines carry calls along electrical cables. Your calls are connected through a wired connection between two handsets. Cell phones send and receive calls by using electromagnetic radio waves to send and receive the calls that would otherwise travel down wires.

Whether you’re in the privacy of your home or walking down a crowded street, you’re surrounded by electromagnetic waves. TVs, radios, radio controlled cars, cell phones and even wireless doorbells work by using electromagnetic energy that moves invisibly through space at the speed of light.

Cell phones are by far the fastest growing source of electromagnetic energy in the world.

How Cell Phone Calls Travel

When you speak into your cell phone, a microphone in the handset converts the high and low sounds of your voice into a corresponding pattern of electrical signals.

The microchip inside the phone then turns these electrical signals into strings of numbers. The numbers are placed into a radio wave and transmitted from the cell phone’s antenna. The radio waves move through the air at the speed of light until they reach the nearest cellular tower.

The cell phone tower receives the signals and passes them on to its base station, which then routes them to their destination. A cell phone handset contains a radio transmitter and a radio receiver. These are not high-powered, which enables them to use less power and save on their battery life. All they need to accomplish is to transmit the signal to the closest cell tower. Cell towers have high-powered antennas and are often situated on the top of a hill or tall building enabling them to receive faint signals.

How Does A Cell Phone Caller ID Work?

A cell phone caller ID is different than a landline caller ID.

While most landlines now have a built-in caller ID that presents the name and number of a caller, cell phones only display the phone number that is calling (unless the phone number is already saved in the phone).

If the caller’s number is in the address book on your wireless phone, then your phone will display their name and number. However, if the number isn’t a part of your contact list, you will need to look up the number.

If you have a call from an unfamiliar number the best way to find the owner’s information is to perform a  reverse phone lookup. You can then gather information on the caller such as name, address and even related people.

While this may work for most people, most of the time, suppose you’re in a situation where there is no cellular reception. This could happen in the middle of a big city with millions of simultaneous calls going on around you or in a rural setting where there are no nearby cell towers. A solution that may be able to help is a cellular signal booster. SureCall carries an award-winning line of cell phone boosters for homes, buildings or cars.
