A huge number of people use cell phones, yet most of them have very little idea of how they work or much about them. In a way, that isn’t surprising, since a lot of people drive or ride in cars and have no idea how the engine works.
However, take a look at these cell phone facts:
* Even when a cell phone powers itself off because of low power, it still continues to send a periodic pulse or ‘ping’ to satellites a couple of times per minute.
* When a cell phone powers itself down because of low power, it actually still has about 40% of its power left in the battery.
* Using triangulation, it is possible to pinpoint the location of a cell phone to within about a meter. This includes altitude, so if a person is inside of a skyscraper, the location of the exact room they are in can be tracked, regardless of which floor they are on.
* No cell phone providers in the US have their own satellites. They pay the US government for the use of communication satellites, but the US government owns and controls those satellites.
* As of 2018, there were a little more than 350 million active cell phones in use in the United States. What makes this amazing is that as of the same year, the population of the US was about 329 million. This means that there are more cell phones being used in the US than there are men, women, and children.
* The average age of people in the US when they get their first cell phone is 11.5 years of age. However, 10% of 5-year-olds in the US have a cell phone.
* 81% of people with cell phones in the US send and receive text messages.
* The US has several hundred communications satellites in orbit.
* The first practical cell phone was produced in 1983, ten years after cell phones were invented. The cost of that phone was $4,000.
* The average smartphone has more computing power than Apollo 11 had when it landed on the moon.
Be honest, of the above 10 facts, how many of them did you NOT know?
I knew all of these facts
