GSM Global System for Mobile Communications was developed to replace the analog cellular network 1Gtherefore it is referred to as a 2G mobile network.
Based on the GSM standard, it is deemed as a 3G mobile network standard. LTE is deemed to be the fourth generation 4G of mobile communications technology.
A further development of the technology is called LTE Advanced. 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 process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.
Microsoft Lumia XL LTE Dual SIM – Specifications
Its main function is to interpret and execute instructions contained in software applications. The CPU bits are determined by the bit-size of the processor registers, address buses and data buses.
Information about the set of instructions the processor can execute.
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.
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.
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 frequency of the processor describes its clock rate in cycles per second.
They handle the computation of graphics in various applications.
Data in the RAM is lost after the device is turned off or restarted. 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.
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.
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 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.
Sensors vary in type and purpose. They increase the overall functionality of the device, in which they are integrated. Information about the sensor type of the camera.
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.
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 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 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.
The model is in its seventh year of production and features improved steering and suspension tuning making it even more attractive to those buying the vehicle as a daily driver. Best BlackBerry Phones 2019: Reviewed and Rated But its solid performance and versatility make it an extremely useful secondary device and one of the best bargains in tech.
Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens.
The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that’s the same as the one of the camera of the mobile device.
It is measured by multiplying the native focal length of the camera by the crop factor of the sensor.
A Tower Mounted Amplifier or Mast Head Amplifier is a low-noise amplifier LNA mounted as close as practical to the antenna in mobile masts or base transceiver stations. Path loss or path attenuation is the reduction in power density attenuation of an electromagnetic wave as it propagates through space. Microsoft lumia 640 xl lte dual sim yukon The neat fascia and quirky dimpled driver is reason enough to keep the grilles off.
The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.
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. One of the main characteristics of the cameras is their image resolution.
