This article will discuss CDMA phones, what kind of devices they are and in what cases you simply cannot do without them. Also, the characteristics of real models will be indicated and recommendations regarding their purchase will be given.
Two main mobile communication standards
At the moment, mobile devices of two standards are most widely used: GSM and CDMA. Each of them is a digital standard. But the signal transmission in each of these cases is carried out in different ways. In the first case, the frequency range is divided into parts, each conversation occupies only a small part of the spectrum. In the second case, the encoding allows the subscriber to use the entire radio frequency resource. As a result, in this case, the quality of communication is an order of magnitude better. But today, devices for mobile networks of the first type have become more widespread. This standard was introduced much earlier and was already actively used at the time of the announcement of CDMA solutions. Now we get the answer to the question: “CDMA phones - what kind of devices are they?” These are devices that are focused on use in mobile CDMA networks. Exactlyalso GSM solutions are used only in such cellular networks.
Supported devices
Many devices are designed to operate in CDMA cellular networks. First of all, these are mobile phones of the corresponding standard. They have a relatively low level of functionality: conversation, text and multimedia messages. In some cases, this list can be extended by data transfer. So the answer to the question: "CDMA phones - what is it?" - is such a definition: "This is a device that allows you to make calls, send and receive text or multimedia messages, or connect to the Internet in CDMA networks." The second type of device that can be used in such networks is modems. They can perform only one task - to ensure the transfer and receipt of data from the global web to a PC. Another type of device is mobile Wi-Fi routers. They do the same thing as modems, but only in this case, the presence of a computer is not necessary to make a connection. The router creates a wireless computing network to which any device with a Wi-Fi transmitter can be connected. The last type of device is smartphones. These are mobile devices, the capabilities of which are enhanced through the use of special software. In this case, you can watch videos, listen to music, and communicate on social networks … You can even use it as a mobile Wi-Fi router.
Operators in Ukraine
Until recently in Ukrainethere were quite a lot of cellular operators that functioned in this standard. These are Velton, Ukrainian Wave, People.net, and Intertelecom. But now only the last two continue to provide services. The first two of them were acquired by Intertelecom, their subscribers joined its cellular network. In turn, People.net, due to economic difficulties, began to "turn off" coverage, because of this, many of its subscribers were forced to switch to its direct competitor, Intertelecom, which after that became the only national CDMA operator. Its subscriber base is based on dual-standard CDMA-GSM phones. Odessa is the city from which this operator began its victorious march across the country. Now its coverage covers most of the country. So owners of CDMA-devices can work in Ukraine only in one cellular network.
Lenovo A330e
5-inch display diagonal and reasonable price are the main advantages of this model. The hardware basis of the device is "Snapdragon 200" with two computing modules. Each of them can theoretically be overclocked to 1.2 GHz. The memory subsystem is represented by 512 MB of RAM and 4 GB of integrated data storage. The capacity of the complete battery is 2000 mAh, which is definitely enough for 2 days of use. The operating system in this case is "Android". The price of this device starts from 6000 rubles.
Huawei Y321C
One of the most affordable devices of this standard is the Huawei CDMA phoneY321C. Although this is already a smartphone that operates under the control of Android. Its computing basis is the 2-core Snapdragon MCM8625 with a peak frequency of 1 GHz. The RAM is 0.5 GB, and the capacity of the built-in storage is “modest” 4 GB. The display diagonal is only 4 inches, and its resolution is 480x800. Responsible for autonomy is a battery with a capacity of 1350 mAh. This is definitely enough for 1 day of work. The price of this device is 5750 rubles.
Lenovo A805e
This is currently the most affordable GSM - CDMA mobile phone with a diagonal of 5.5 inches. Its computing core is a 4-core Snapdragon 410 CPU. Each of its computing modules can increase its frequency up to 1.2 GHz. Comfortable work on this device is provided by 1 GB of RAM and 8 GB of integrated storage. A 2500 mAh battery is responsible for autonomy, this is quite enough for 1-2 days of battery life. The price of this gadget is 8000 rubles.
HTC T329d
HTC also has solutions for this digital standard. CDMA-standard phones from this manufacturer, although not so often, can still be found. One of the most affordable models is the HTC N329d. Like all previously reviewed gadgets, this smartphone is dual-band and can work simultaneously in both CDMA-network and GSM-coverage. At the heart of this device is a 2-core CPU that can dynamically overclock up to 1 GHz. The amount of RAM is 768 GB, and the built-in storage capacity is 4 GB. Screen diagonal - 4inches. The resolution of 800x480 allows you to display the output image with sufficient quality. The battery capacity allows you to count on 2 days of battery life without recharging.
The device is equipped with a variety of wired and wireless ways to transfer information, which allow you to fully unleash its potential. You can buy such a device now for 7500 rubles.
