Nfc? Understand What Is Written On The Box Of The Smartphone

NFC, MHL, dual core, Glonass. This alphabet soup is well known to anyone who has ever searched for information on a smartphone. Unfortunately, many sites of manufacturers bring few explanations of the meaning of each symbol or about your usefulness in daily life. With that in mind, the iG has prepared a quick guide with explanations of the acronyms that more appear in smartphones. Check out.

Dual core/Quad core Chip/Octa core-these terms refer to the number of processor cores (dual core, dual-core; quad core, quad-core; core, eight-core octa). The number of cores is indicative of the processing capacity of the chip, but not only.

RAM-is the memory used to run applications and, along with the processor, is what makes the device faster. The values range from 512 MB to 3 GB in base units on top of the line appliances.

Storage-is the memory used to install applications and save music, videos and other file types. Goes from 4 GB to 128 GB in basic smartphones and very advanced models.

SIM/MicroSIM/nanoSIM-types of cellular carrier chip on the market. The SIM is the largest size, used in cell phones and most smartphones with support for two or more chips. The MicroSIM is increasingly common in intermediate and top-of-the-line smartphones. Some devices use even smaller chip, nanoSIM.

GPS/Glonass-GPS is a global navigation satellite system primarily used in maps and transit applications developed initially by the Government of the United States. Some smartphones support also the Glonass system, which is nothing more than an alternative to GPS created by Russia.


Edge/3 g/3.5 g/4 g/LTE-Are standards used to identify the connection speed to the internet. The Edge corresponds to the 2 g, with very low speed. The 3 g has real average speed between 1 and 2 Mbps with 3 g + (WORLD standard +) that speed can reach about 6 Mbps. 4 g already (most common name of the technical standard LTE) has speed that usually stay over at 20 Mbps.

Wi-Fi b/g/n/ac-Wi-Fi is wireless networking standard used for internet access. Most smartphones on the market supports version n, but some more advanced devices also work with the ac network, faster. But this speed gain only occurs if the phone is on a wireless network that also runs on standard ac.

Wi-Fi Direct-this feature allows you to transfer content between smartphones through a Wi-Fi network even without a router around. The cell phone equipped with Wi-Fi direct can create your own network and connect to other devices. In practice, the Wi-Fi Direct can replace Bluetooth in certain situations, providing a faster connection (but consuming more battery).

Wi-Fi hotspot-is the feature that allows you to use the mobile to share the 3 g/4 g connection using a wireless network, and with password set by the owner of the appliance. Present in all smartphones on the market.

USB On The Go (OTG)-Is a feature that allows the smartphone is connected to Flash drives, keyboards and other USB peripherals.

NFC (Near-field Communication)-Currently, this technology is used, basically, to facilitate communication between the smartphone and accessories such as speakers and wireless smart watches. When the user approaches the smarphone with NFC compatible equipment module, synchronization occurs from instant mode. After synchronization, another wireless standard (usually the Bluetooth) is used for data transfer. The NFC is also used in mobile payment systems, such as Apple Pay.

-Bluetooth short-range wireless technology used primarily to connect the smartphone to headphones and speakers. The latest version, and with less battery consumption, is the 4.0 LE (Low Energy).

Miracast-technology that allows the smartphone send audio and video to the TV, without the use of wires or Wi-Fi network. The TV, however, also have to be compatible with Miracast.

DLNA-Has basically the same Miracast function, but is older and has been falling into disuse.

MHL-pattern used to send audio and video from a smartphone to a high definition TV. The default MHL uses port miniUSB smartphone to send audio and video to the TV. It is necessary, however buying a cable MHL. This cable has one end compatible with microUSB (attached to the smartphone) and other end HDMI (docked on TV).


qHD/HD/Full HD/QuadHD-are symbols that identify the device’s screen resolution. The qHD corresponds to the resolution of 960 x 540, the HD is 1,280 x 720; 1,920 x 1,080 full HD, 2,560 x 1,440 QuadHD,.

Pixel density-Nothing more than the total number of pixels divided by your screen area, in inches. When we say that a phone has 240 dpi (dot per inch) or 240 dpi (pixels per inch), we’re saying that every square inch of the screen behave 240 pixels. So, depending on the resolution, mobile phones with screens of the same size may have different densities.

IPS (In Plane Switching)-This technology is used to ensure a better picture with his cell phone. Is present in most intermediate and appliances in all higher end models.

Gorilla Glass-Manufactured by American company Corning, the Gorilla Glass is high-strength glass used to protect the screen of some intermediate and sophisticated smartphones. The modern version is resistant Gorilla Glass 3, but 4 version will be soon in the market.


-LED Flash is the flash type of camera that uses an LED lamp to illuminate the scene. This is the most common flash type. Some cutting-edge smartphones use xenon flash (xenon flash), similar to those used in cameras.

Optical stabilization-is a set of sensors and small gears that compensate in real time the shaky, which provides pictures with less smudging. A few phones on the market use this technology.


mAh (Milli-Ampere-hour)-Is the unit that measures the ability of cell and battery load usually between 2,000 and 3,000 mAh mAh. As each phone has a different energy consumption, the duration of the same battery can vary.
