GSM (Global System for Mobile Communications) is designed to replace the analog mobile network (1G). For this reason, GSM is often referred to as a 2G mobile network. It is enhanced by the addition of GPRS (General Packet Radio Services) and later EDGE (Enhanced Data rates for GSM Evolution) technologies.

UMTS stands for Universal Mobile Telecommunications System. It is based on the GSM standard and refers to 3G mobile networks. Developed by 3GPP and its biggest advantage is to provide more speed and spectral efficiency thanks to W-CDMA technology.

LTE (Long Term Evolution) is defined as a fourth generation (4G) technology. It is developed by 3GPP based on GSM / EDGE and UMTS / HSPA with the aim of increasing the capacity and speed of wireless mobile networks. The subsequent development of technologies is called LTE Advanced.

A system on a chip (SoC) integrates various hardware components such as a processor, graphics processor, memory, peripherals, interfaces, etc., as well as the software required for their operation.

Information about the technological process by which the chip is manufactured. The value in nanometers is half the distance between the elements in the processor.

The main function of the processor (CPU) of a mobile device is to interpret and execute instructions contained in software applications.

The capacity (bits) of the processor is determined by the size (in bits) of registers, address buses and buses for data. 64-bit processors offer better performance than 32-bit processors, which in turn are more efficient than 16-bit processors.

Instructions are commands with which the software sets / controls the processor. Information about the instruction set (ISA) that the processor can execute.

Some processors have L0 (level 0) cache memory, which can be accessed faster than L1, L2, L3, etc. The advantage of having such memory is not only higher performance, but also lower power consumption.

The cache memory is used by the processor to reduce the time it takes to access more frequently used data and instructions. L1 (level 1) cache is small and much faster than both system memory and other levels of cache. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2.

L2 (level 2) cache is slower than L1, but instead has a larger capacity to cache more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for them in L3 cache memory (if available) or in RAM memory.

The processor core executes program instructions... There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to execute in parallel.

The clock speed of a processor describes its speed in cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz).

A graphics processing unit (GPU) handles computation for a variety of 2D / 3D graphics applications... V mobile devices ah, it is used most often by games, consumer interface, video applications, and more.

The speed of work is clock frequency the GPU, which is measured in megahertz (MHz) or gigahertz (GHz).

Random access memory (RAM) is used by the operating system and all installed applications. The data that is saved in the RAM is lost after the device is turned off or restarted.

Information about the type of random access memory (RAM) used by the device.

Information about the number of RAM channels which are integrated into the SoC. More channels means more high speeds data transmission.

The frequency of the RAM determines its speed of operation, more specifically, the speed of reading / writing data.

One of the main characteristics of the screen is the technology by which it is made and on which the image quality of information directly depends.

On mobile devices, screen size is expressed in terms of the length of its diagonal, measured in inches.

Approximate screen width

Approximate screen height

The aspect ratio of the long side of the screen to its short side

Screen resolution shows the number of pixels horizontally and vertically on the screen. More a high resolution means sharper image detail.

Information about the number of pixels per centimeter or inch of the screen. Higher density allows information to be shown on the screen in clearer detail.

Screen color depth reflects the total number of bits used for color components in one pixel. Information about the maximum number of colors that the screen can display.

The approximate percentage of the display area on the front of the device.

Information about other functions and features of the screen.

Information about the manufacturer and model of the photocell used in the camera of the device.

Digital cameras use photo sensors to take photographs. The sensor, as well as the optics, are one of the main factors in the quality of the camera in a mobile device.

Information about the dimensions of the photosensor used in the device. Typically, cameras with a larger sensor and lower pixel density offer more high quality images despite the lower resolution.

The smaller pixel size of the photosensor allows more pixels per unit area to be used, thus increasing the resolution. On the other hand, a smaller pixel size can have a negative impact on image quality when high levels sensitivity (ISO).

The crop factor is the ratio between the size of a full-frame sensor (36 x 24 mm, equivalent to a frame of standard 35 mm film) and the size of the device's photo sensor. The number shown is the ratio of the diagonals of a full-frame sensor (43.3mm) to that of a specific device.

ISO values ​​determine the level of light sensitivity of the photosensor. A lower value means weaker light sensitivity, and vice versa - a higher value means a higher light sensitivity, i.e. better ability of the sensor to work in low light conditions.

Aperture (f-number) is the size of the aperture opening that controls the amount of light reaching the photosensor. A lower f-number means a larger aperture opening.

The most common types of flashes in mobile cameras are LED and Xenon flashes. LED-flashes give softer light and, unlike brighter xenon ones, are also used for video filming.

One of the main characteristics of cameras on mobile devices is their resolution, which shows the number of pixels horizontally and vertically in an image.

Information about the maximum supported resolution for video recording by the device.

Information about the maximum number of frames per second (fps) supported by the device when shooting video at maximum resolution. Some of the main standard video capture and playback speeds are 24p, 25p, 30p, 60p.

The SAR level indicates maximum amount electromagnetic radiation to which the human body is exposed if you hold a mobile device close to your ear in a talking position. In Europe, the maximum SAR value for mobile devices is limited to 2 W / kg per 10 grams of human tissue. This standard established by the CENELEC committee in accordance with IEC standards, following the ICNIRP guidelines of 1998.

The SAR level indicates the maximum amount of electromagnetic radiation that a person's body is exposed to when holding a mobile device at hip level. The highest SAR value for mobile devices in Europe is 2 W / kg per 10 grams of human tissue. This standard was established by the CENELEC committee in accordance with ICNIRP guidelines from 1998 and IEC standards.

The SAR level indicates the maximum amount of electromagnetic radiation that a person's body is exposed to if a mobile device is held close to the ear. The maximum value used in the United States is 1.6 W / kg per gram of human tissue. US mobile devices are controlled by CTIA and the FCC conducts tests and sets their SAR values.
