LTE is deemed to be the fourth generation (4G) of mobile communications technology. It has been developed by the 3GPP based on the GSM/EDGE and UMTS/HSPA technologies in order to increase the speed and capacity of wireless data networks. A further development of the technology is called LTE Advanced.
UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology.
GSM (Global System for Mobile Communications) was developed to replace the analog cellular network (1G), therefore it is referred to as a 2G mobile network. It has been improved with the addition of General Packet Radio Services (GPRS) and later via the Enhanced Data rates for GSM Evolution (EDGE) technology.
There are several network technologies that enhance the performance of mobile networks mainly by increased data bandwidth. Information about the communication technologies supported by the device and their respective uplink and downlink bandwidth.
Information about the operating system used by the device as well as its version.
Information about the number of RAM channels integrated in the SoC. More channels mean higher data transfer rates.
Information about the type of RAM used by the device.
RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.
The frequency is the clock rate of the graphic processor (GPU), which is measured in Megahertz (MHz) or Gigahertz (GHz).
GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. In mobile devices GPU is usually utilized by games, UI, video playback, etc. GPU can also perform computation in applications traditionally handled by the CPU.
The frequency of the processor describes its clock rate in cycles per second. It is measured in Megahertz (MHz) or Gigahertz (GHz).
A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.
The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM.
The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. In some processors the search in L1 and L2 is simultaneous.
Some processors have a level 0 cache memory, which is accessed quicker than the L1, L2, L3, and so one cache memories. Besides achieving better performance, it also consumes less power.
The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU’s work. Information about the set of instructions the processor can execute.
The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors.
CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications.
Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.
The SoC integrates different hardware components such as the CPU, GPU, memory, peripherals, interfaces, etc., as well as software for their functioning.
Information about the capacity of the built-in storage of the device. Sometimes one and the same model may is offered in variants with different internal storage capacity.
The various types of memory cards are characterized by different sizes and capacity. Information about the supported types of memory cards.
Information about other functions and features of the display.
The estimated percentage of the screen area from the device’s front area.
The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display.
Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen.
The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content.
The ratio between the long and the short side of the display
In mobile devices display size is represented by the length of its diagonal measured in inches.
One of the main characteristics of the display is its type/technology, on which depends its performance.
Sensors vary in type and purpose. They increase the overall functionality of the device, in which they are integrated.
Sensor model
Information about the manufacturer and model of the image sensor used by this camera of the device.
Toshiba T4K37Sensor type
Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc.
CMOS BSI (backside illumination)Sensor size
Information about the dimensions of the image sensor used in the device. Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution.
4.69 x 3.52 mm

(inches)
Pixel size
Pixels are usually measured in microns (μm). Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. On the other hand, smaller pixels allow for increasing the resolution while preserving the same sensor size.

Crop factor
Crop factor is the ratio of the dimensions of a full frame camera’s sensor (36 x 24 mm, which equals the frame size of a 35 mm film) and the dimensions of the image sensor of the device. The number shown is the ratio between the diagonals of a full frame sensor (43.3 mm) and the sensor in question.
7.38Aperture
The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
f/2Number of lenses
Information about the number of lenses used by the optical system of the camera.
5Flash type
The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements.
Dual LEDImage resolution
One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.
