How the phone works

In this article we will explain the basic physical principles of why and how phones work, these devices are featured in the 80s in the United States and that have revolutionized the communication system. Read carefully to find out how mobile works.

Steps to follow:

1. Each cell has a base station consisting of a tower and a small building containing radio equipment.

2. Each cell in an analog system uses one seventh of the existing voice channels. That is, one cell, plus six cells surrounding it in a hexagonal arrangement, each using one seventh of the existing channels so that each cell has a unique and non-collision frequency group:

3. Cellular service providers usually receive 832 radio frequencies for use in the city.

4. The phone uses two frequencies per call, so there are usually 395 voice channels per signal carrier. (The remaining 42 frequencies are used as control channels). Therefore, each cell has about 56 available voice channels.

5. The phone has a low power transmitter in it. Many phones have two signal strengths: 0.6 watts and 3.0 watts (as a comparison, most civil radio bands transmit at 4 watts). The central station also transmits at low power. Low-power transmitters have two advantages.

6. Transmission centers and phones in the same cell do not leave this one. Therefore, each cell can reuse the same 56 frequencies through the city.

7. The power consumption of mobile phones, which generally work with batteries, is relatively low. Low power means smaller battery.

8. Phone technology requires a large number of bases or stations in cities of various sizes. A big city can have hundreds of towers. Every city needs to have a central office that manages all telephone connections to conventional phones, and controls all stations in the region.

How to Avoid Mobile Battery Damage

                                
One of the most important things to do to maintain the health of your smartphone battery and ensure better battery life, and its safety, is through the correct charging. By simply plugging in your USB porting phone as soon as you get home and let the charger until you leave for work the next morning is a bad idea.

We'll let you know some tips and tips on how to maintain your phone properly. But the details often vary - everything depends on your smartphone model. For that reason, we decided to give you tips on how to optimize your smartphone battery.

Do not leave the phone too hot

In most tips on saving your phone battery, heat seems to be the worst enemy of lithium-ion batteries - the kind most used by smartphones. We recommend that you also avoid charging the phone while playing graphics intensively. Why? This is only because it will likely raise the temperature of the phone and harm the battery. Note: the highest filling temperature is between 20-30 degrees Celsius.

Avoid playing games, calling, or even texting while charging

As a general rule, smartphone users should avoid using the phone while it is charging. The use of this kind seems to be very destructive. A small amount of usage load prevents the battery from entering the full charge cycle, thus damaging the battery.

Never use a fake charger

Wherever and whoever you are asking for advice on battery savings, nobody will suggest using substandard or fake chargers. And these people also recommend using only legitimate corporate or brand chargers - this is very important if your phone supports fast charging. How about using a high-capacity charger to quickly charge your phone up to 70 percent? While it is fun to do so, quickly charging your phone, there is a tendency to damage the battery and the phone while in the process - especially if it is not optimized properly.

"Using a higher current than specified reduces the capacity of long-term battery cell retention, so using a non-standard charger for fast charging is not good."

Remember when we were advised to fill up the new phone we just bought? Well, there's no need to do that this time because the manufacturer fills up your new phone completely when you buy it. It is not advisable to charge the battery up to 100 percent at all times, as you can start using it and run the battery before putting it in full charge again. Conversely, leaving the battery down to zero is also not a good idea.

"Do not let your battery die completely if you can avoid it, I recommend charging it until it's about 10 percent charged, this extends the battery life."

Never leave the phone on the charger overnight

Well, not true if your phone is on cash overnight, it will not damage it. There is a high probability of lowering the battery life. You should remove it at night.

Once the smartphone battery voltage reaches its capacity, it will automatically disconnect. However, it does not matter whether your phone remains plugged after it is fully charged because it will not interfere with the battery.

However, therefore, they still recommend retracting the phone when it reaches full charge. In addition, charging up to 100 percent each day increases the percentage of aging.

The battery has a fixed life cycle and you can not extend its life indefinitely, but there are few ways to not speed up its life by using USB portable chargers from time to time. This tiny gadget is not only meant for travel but also a design to replace your phone battery.
