Product Information

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.

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. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoCA rare piece of kit that I will certainly grow old with rather than upgrade like all my other bits of kit. Read less 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.

Specific Absorption Rate (SAR) The SAR rating shows the amount of electromagnetic radiation absorbed by the human body when using a mobile device, expressed in W/kg. Head SAR (EU) This SAR rating shows the highest level of exposure to electromagnetic radiation measured when the device is placed at the hip level. The top SAR value for mobile devices used in Europe is limited to 2 W/kg per 10 g of tissue. This standard follows the ICNIRP Guidelines 1998 as well as the IEC standards and is determined by the CENELEC. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications.Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM 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 sketch pen is amazing as I often need to do small sketches on the side on my tapped data input numerals. Having the Tab2 camera right on the surveying pole is also a gain as I don't have to fire up a camera or phone to take on the go shots of features. 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 additional software and hardware features of the front camera which improve its overall performance. 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 SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard. Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. 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.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. This SAR rating shows the maximum level of exposure to electromagnetic radiation taken when the device is placed next to the ear. The applicable limit for the US is 1.6 W/kg per 1 g of tissue. In the US the FCC tests and sets the SAR limits for all mobile devices, which are controlled by the CTIA. 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. Information about additional software and hardware features of the rear camera which improve its overall performance.
