Mobile Phones: Advantages and Disadvantages
If you know all the advantages and disadvantages of mobile phones, then it is easier for you to decide whether you need a cell phone or not. But some people doubt whether it is worth buying a mobile phone or it is better to be left without it at all.
Pros of mobile phones
The advantages of a cell phone include:
- The ability to quickly communicate with the people you need. And also yourself to always stay in touch. This is especially important for those people whose work is connected with the traveling lifestyle.
- The ability to quickly find out news, view mail, go online.
- A modern phone includes the function of a camera, a player, and also records video. The number of megapixels is enough to get high-quality photos, so there is no need to carry a camera around with you.
- By purchasing a phone for a child, you can be sure that your child will always be in touch.
Disadvantages of phones
You should think about whether it is worth buying a cell phone because the disadvantages are in:
- The fact that mobile can cause headaches, provoke anxiety and cause Alzheimer’s disease. This is the opinion of British scientists who have conducted a number of scientific studies.
- Prolonged use of the Internet from the phone or reading books from it can lead to poor health, cause pain in the temples.
- If a person communicates frequently on the phone, then over time, he concludes that it is better to meet in life than to communicate on a mobile phone.
- Mobile phones do not have eternal batteries, and if you have an interrupted important conversation due to the fact that the phone has sat down, it can cause a nervous breakdown.
- Many are scared off by the price of phones. Those that are cheap do not inspire any confidence, and those that have a high price become inaccessible to many.
- Some phone owners do not like the fact that they often have to top up their balance. They would rather pay a certain amount once a month and talk for any amount of time.
What can be done from a broken phone: use cases
The modern consumer changes mobile devices so often that sometimes instead of a repair problem, he is faced with the question of disposing of an outdated device.
Our article will tell you about what can be done with a broken phone – provided that it is not completely out of order.
Simplest ways to use
(1) If the user has at least basic knowledge in the field of microelectronics, he will be able to make many useful devices out of an old phone, which will be turned on by a remote signal.
(2) For example, an old phone can be used to make a video surveillance device, as well as an ordinary “bug”.
(3) In addition, it will be able to make an alarm (both simple and anti-theft), a GPS navigator or a car DVR, or a barcode scanner.
(4) In most cases, it is required that the built-in camera and speaker remain operational. In addition, additional software may be required.
(5) You can find a suitable program on the net. All this will give the old phone a second life.
(6) It is noteworthy that you can even make a charger from a mobile device, which will be used as a means of recharging the battery of another smartphone.
(7) If we want to make a video surveillance device, a working camera of 3-16 megapixels is required. In this case, you will also need a large memory card.
(8) A suitable program is downloaded from the Internet and installed on a PC, after which they connect the phone with the recorded video to the computer via a USB cable and view the recording.
(9) Similarly, you can use your mobile device as a web-camera, which is also quite convenient. If we need a long USB cable for any purpose, it can be ordered online with a designation such as high-speed.
(10) Using additional technology, we will be able to make equally useful devices from our apparatus. For example, a metal detector can be made from a radio and a telephone.
(11) The principle of its operation is that the mobile phone will create the desired wave by acting on the radio receiver, and the metal will distort the frequency sounds. The idea of turning the phone into an anti-theft device looks no less useful.
(12) So, our mobile device can become a remote control, a battery, a tracking device, an additional part for assembling a flashlight, and much more.
(13) It can even be used to emulate older game consoles if desired. In other words, if we are patient, we will surely find a worthy use for our old phone.
What is a radio module in mobile phones?
The question, what is a radio module in a phone, users began to ask themselves after the need and desire arose to use two SIM cards at the same time.
Until that moment, only those who were interested in poking around in mobile devices, as well as mobile phone repairmen, were interested in the question of the radio module in the phone.
What is it for
The radio module in your phone allows you to receive and transmit network signals, which means that:
- You can call.
- They may call you.
- Receiving and sending text and multimedia messages.
- And finally – the ability to use the mobile Internet to visit your favorite social networks and for work!
A radio is a small area on the motherboard that receives radio signals.
The blade of the radio module or its incorrect installation, the installation of an unsuitable radio module for the board, the presence of metal parts next to it, leads to a decrease in the quality and strength of the signal until the message “Network not found / Searching for a network” appears on the screen.
It is the use of various radio modules, the difference in their installation by manufacturers, and says that one phone will be caught in the underpass, the second phone will fail, and the third simply will not show the network signal.
In addition to the electronics itself, specialized software should be considered a radio module in the phone. These are driver libraries that make all hardware parts of the phone work and “communicate” with each other.
Radio module and two SIM cards
- Programmers and engineers have learned how to make one radio module work with two (and even three!) SIM cards, namely with two different networks and phone numbers.
- But when actively working with one network, the second network (second SIM card) becomes unavailable. The use of two radio modules solves this problem.
- Both networks are available anytime and anywhere where there is network coverage, but the simultaneous operation of two radio modules greatly reduces the battery life of the phone.
