GSM (Global System for Mobile Communications) is designed to replace the analogue 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 is short for Universal Mobile Telecommunications System. It is based on the GSM standard and belongs to 3G mobile networks. Developed by 3GPP and its biggest advantage is to provide more speed and spectral efficiency with W-CDMA technology.

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

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

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

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

The bit depth (bits) of a processor is determined by the size (in bits) of registers, address buses, and data buses. 64-bit processors have higher performance than 32-bit processors, which, in turn, are more productive than 16-bit processors.

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

Some processors have an L0 (level 0) cache that is faster to access than L1, L2, L3, etc. The advantage of having such a memory is not only higher performance, but also reduced power consumption.

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

L2 (level 2) cache is slower than L1, but in return it has a larger capacity, allowing more data to be cached. 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 it in the L3 cache (if available) or RAM.

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

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

Graphics Processing Unit (GPU) handles calculations for various 2D/3D graphic applications. V mobile devices ah it is used most often by games, consumer interface, video applications, etc.

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

Random access memory (RAM) is used by the operating system and all installed applications. Data stored in RAM is lost when 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 that are integrated into the SoC. More channels means more high speeds data transmission.

The frequency of RAM determines its speed, 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.

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

Approximate Screen Width

Approximate Screen Height

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

Screen resolution indicates the number of pixels vertically and horizontally 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 the color components in a single pixel. Information about the maximum number of colors the screen can display.

Approximate percentage of screen space on the front of the device.

Information about other functions and features of the screen.

Information about the manufacturer and model of the photo sensor used in the device's camera.

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

Information about the size 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 to be used per unit area, thus increasing resolution. On the other hand, a smaller pixel size can have a negative impact on image quality when high levels light sensitivity (ISO).

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

ISO values ​​determine the light sensitivity level of the photosensor. A lower value means weaker light sensitivity and vice versa - higher values ​​mean 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 the aperture is larger.

The most common types of flashes in mobile devices cameras are LED and xenon flashes. LED flashes give a softer light and, unlike brighter xenon flashes, are also used for video shooting.

One of the main characteristics of mobile device cameras is their resolution, which indicates the number of pixels in the horizontal and vertical direction of 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 the maximum resolution. Some of the main standard shooting and video playback speeds are 24p, 25p, 30p, 60p.

The SAR level indicates maximum amount electromagnetic radiation that the human body is exposed to when holding a mobile device next to the ear in a conversation position. In Europe, the maximum allowable SAR value for mobile devices is limited to 2 W/kg per 10 grams of human tissue. This standard established by CENELEC in accordance with IEC standards following ICNIRP guidelines of 1998.

The SAR level indicates the maximum amount of electromagnetic radiation that the human body is exposed to when holding a mobile device at hip level. The maximum allowed SAR value for mobile devices in Europe is 2 W/kg per 10 grams of human tissue.

The SAR level indicates the maximum amount of electromagnetic radiation that the human body is exposed to when holding a mobile device near the ear. The maximum value used in the US is 1.6 W/kg per gram of human tissue. Mobile devices in the US are controlled by the CTIA and the FCC conducts tests and sets their SAR values.

The SAR level indicates the maximum amount of electromagnetic radiation that the human body is exposed to when holding a mobile device at hip level.
