If we decipher in detail the full abbreviation of these four letters (CDMA), then we get the following words - Code Division Multiple Access. And even when we decipher this meaning, translating it into a language we understand, we will be able to understand little of it. We note that if we translate this phrase from English, then we get the fact that this is a system of a large number of code division access. This is exactly what CDMA phones are. They are becoming more and more popular today. And this is not at all surprising. In more detail what it is, CDMA phones, we will analyze later in our article.
What is a CDMA phone
In order to understand the whole essence of this technology, which is not at all simple, we can draw a certain analogy. It is with the help of it that we will understand in general terms what this thing is. It will be much more convenient and legible for everyone if we draw an analogy with this phone standard. As we all know, there are several mobile connections, the most common of them are GSM and NMT.
NMT connection
So, let's look at what it is, CDMA phones. In many countries, it is with the help of the NMT-connection of a mobile phone that many operators began their work. Then they used the so-called private division of certain channels. Based on this, we can understand that each direct subscriber was given his own rather narrow aspect of frequencies. It was through this that he could conduct his communications. This species has recently fallen into disrepair. And here's the reason. Imagine that there are 3 people on one square meter, and each of them actively communicates on the phone. There is absolutely no comfort. Now they're far enough away that they can't hear each other.
This is how we explain the frequency division of the channels. This is what CDMA phones use. It is due to such a comparison that some details become clear in general terms.
GSM digital standard
This is the digital communication standard we use in everyday life. In various countries it still carries out its direct function. This system, in turn, uses the tuned frequency range in a different way. This type of connection does not divide a certain range into specific parts absolutely for each user. But the program does it at a certain point in time. This is the temporary separation of the channels we need. That is, a certain pair of people speak at a certain time that they need, and the other pair speaks at their own time, and at the same time, without creatingdiscomfort for other people. Approximately according to such a system, CDMA standard phones also carry out their direct work. But we will talk about this in more detail in the next section.
CDMA communication standards
So, we smoothly approached the standard we need. He, in turn, uses a certain range as the previous type of connection, but does it in a slightly different way. For example, due to a certain code separation. What is the code separation in this case, it is rather difficult to imagine, so let's return to the analogy. If people talk nearby and interfere with a friend, this is bad, but if each pair of people speaks their own language, that is, one in Russian, the other in English, and so on. This is what this link to code communication is. Now we know in general terms what it is, CDMA phones. But still, this information is not available to us in as much detail as we would like.
History of the best connection to date
The services of various rather serious operators, because Intertelecom was also on a par with CDMA, began to be provided back in the distant 2000. Everyone understands that at that time the cost of phones was high, and it was also not easy to find a terminal. But still, this connection had its demand, albeit small. Each operator at that time had its own range of services with which it attracted customers. This operator has developed gradually, and over the years, its connection cost has significantly decreased, and the quality of services has notstopped growing. This attracted more and more customers every year. To date, we have a fairly low price, while a large number of advantages.
It is also worth noting the range of this type of communication, because you can choose for yourself the tariff that suits you best.
The advantages of this type of connection
CDMA-phones today entered into operation quite widely and are extremely popular. From this we can understand that there are really many advantages in this form. A fixed CDMA phone includes a wide range of services with the help of this connection, let's consider this in more detail.
- First of all, it is necessary to note the quality of communication. It is in this case that this quality represents the highest parameters of all possible types of communication. With such a connection, you will hear a person with such a quality, as if he is standing right in front of you. And this will contribute to the fact that you can distinguish even unidentified numbers only due to the voice of a person on the other side of the telephone connection.
- This connection is perfectly protected from various degrees of wiretapping, which cannot but please the consumer. CDMA phones have equipment to their credit that is not so easy to listen to. In order to ensure listening to one or another such phone, it is necessary to have equipment worth several tens of thousands of US dollars.
- The station of this operator can, in turn, provide communication to a larger number of subscribers than others similar to itoperators.
- As for the beams emitted by CDMA mobile phones, due to this type of connection, this aspect represents a smaller amount of these beams. And this is good news.
Information about what these CDMA phones are is fully disclosed. Now you have complete information about this device and its immediate features. Thus, a CDMA phone allows you to independently choose a suitable operator, as well as vending tariffs for calls, as well as Internet access. Therefore, you can safely and without hesitation switch to operators of this type of communication.
