Mobile cell phones are an example of the change in the way we communicate. Earlier, everyone had to depend upon landlines. Also, the lack of proper connectivity made communication difficult. But, now with increasing access of mobile phones, communication is not restricted to the big cities only.
How Does A Mobile Cell Phone Work?
For laymen, it appears as a simple procedure- it is wireless, you make a call and within seconds, you are speaking to the other person at the receiving end of the connection. But it is not easy as it sounds!
Every area is divided into cells (that’s why mobiles are also known as “cellular” phones). Every mobile phone has an inbuilt antenna that connects with the radio waves and makes the communication possible.
It works like this- after you press the call button, the antenna identifies the nearest network system and connects the radio signal emitting from your phone with the wired telephone system. It then identifies the nearest antenna in the cellular area of the person you are calling. And suppose, the signal fails to connect with the nearest antenna, then it begins to locate other antennae to connect the signal. This seems a long drawn procedure but this entire procedure takes place within seconds.
Also, when you utter, suppose, “Hello” it gets converted into radio waves first, travels, converts again into the word “hello” and then reaches the ear of the person listening at the other end. For a successful and uninterrupted connection, your network needs to know the location of your cell phone. This happens automatically- the inbuilt antennae are in constant touch with the nearest antenna.
Extensive Features of Phones
Gone are the days when a mobile cell phone was used for calling purposes only. Technology has revolutionized the way people connect, communicate and entertain themselves- these are broadly the 3 aspects of a cell phone.
- Mobiles are like mini computers. If your mobile has an internet facility, then what’s the use of PC or a laptop? On mobile, you can watch movies, catch the latest news and even get hold of match scores.
- Users can get in touch through SMS if they cannot call. This is because the rate of an SMS is cheaper than call rates. It is very convenient- for teenagers and senior citizens alike.
- Phones also double up as an MP3 player- recording playback songs.
- With phones, the gaming industry have increased manifold. It is a million dollar industry today.
In all, mobile cell phones are a miracle for humans. Without them, it is impossible to cope up with the fast paced living.
