Cell phones, almost everybody has at least one today from your little girl in elementary school on up to your grandma. In fact, today as cell phones have so many features and functions that it is hard to imagine just a few years ago that a cell phone would ever come in useful. Here we will take a look at how do cell phones work, as well as some cool new cell phone accessories.
How do cell phones work
The first question that must be answered when asking how do cell phones work is – do they actually work? This may seem like a simple answer, but the truth is that they only work while the signal remains within the range of the cell phone’s battery. In other words, the signals are trying to reach the rest of the world and if they were to drop their signal for any reason, the phone would not work. This means that in order for them to work, the battery must stay charged. So how do they keep their batteries charged?
Basically, the answer is complicated. One of the most common theories is that the battery uses low-power FM frequencies which are similar to the ones that are used by radio transmitters. This would explain why there are so many of transmitter devices on the market; they are just variations on the same theory. Unfortunately, there are still no clear answers as far as how the low-powered FM frequencies are transmitted and received.
Wireless technology
Now that we know how do cell phones work, the next question that many people wonder about is – how do cell phones work with wireless technology? This is where things get interesting. For a long time, it was believed that cell phones did not use the same basic technology that wireless devices used. In fact many people went to the extreme and believed that cell phones did not use any form of wireless technology at all. Things are changing.
Cell phones have entered the twenty-first century using an advanced form of radio-frequency transmission. These signals are being used to send short bursts of data at a very high bandwidth. The difference in this case is that instead of radio waves being used, the waves being used are in the form of infrared radiation. This is known as millimeter-wave technology. This is being used to transmit voice, data, and multimedia over long distances.
One example of the new form of wireless technology is Cordless Phones. Cordless phones can be obtained for a reasonable price these days. In addition, you can find a huge number of dealers who specialize in selling cordless phones. This has increased the competition within the marketplace and resulted in some very good prices. There is also a very strong market for cell phones with voice calling capabilities. The competition has resulted in excellent deals on both the buying and selling of cordless phones.
Base Station technology expanses the range of cell phones
Another example is the Base Station technology. Base stations are used as a communications network by detecting the presence of a person or a thing within a large area. They then transmit their signals using a series of low-power transmitters. This system works well when the coverage area is quite large because each station only needs to have the necessary frequencies. This type of system has come under a lot of criticism over the years because of the incidence of false signals emanating from the various cell phones transmitting in the same direction.
A very promising technology that has been developed recently is the Cell Phone System with Satellite Applications. This technology consists of a small satellite dish attached to the cell phone itself. Instead of the usual cells, the satellite dish locates the satellite signal. Once the signal is detected, the signal is converted into usable sound for your cell phones.
