How does a mobile phone know where?
Modern smartphones provide ways for the phone to determine its own location, often using GPS and sometimes using other services provided by location companies (which usually ask the company to guess the phone’s location based on a list of cell phone towers and/or Wi-Fi networks that the phone can see from where it is).
How do cell phone signals travel?
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 does a cell tower know where to send the signal?
Whenever a cell phone is used, it emits an electromagnetic radio wave, called a radio frequency, that is received by the nearest cell tower’s antenna. Once the cell tower receives this signal, it will transmit the signals to a switching center.
How far do cell phone signals go?
Maximum Distance A typical cellphone has enough power to reach a cell tower up to 45 miles away. Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably.
Can a cell phone be traced to an exact location?
Smartphones can still be tracked even if location services and GPS are turned off, according to Princeton University researchers. The technique, called PinMe, shows it is possible to track a location even if the location services, GPS, and Wi-Fi are turned off.
Where does my cell signal come from?
When you’re talking on a cell phone, it converts your voice into a signal that is transmitted via radio waves to the nearest cell tower. The cell tower then relays the radio wave back to the person you’re speaking to, converting it first to a signal and then back to sound again.
What is a cellphone signal?
A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength will vary.
Where from does it come to mobile towers?
Signal comes to mobile towers from satellites.
