 The difference between 3g and 4g

The difference between 3g and 4g

The difference between 3G and 4G first: 



3G technology: 



The third-generation word (3G) reflects the third generation in wireless communication techniques and exceeds its previous wireless techniques, which enjoys high speed data transfer, * Third generation technology is more useful in mobile phones; To provide a way to connect to the Internet, or to download and raise data, or make voice communications or video communications (in English: Video Calls); Pursuant to Wi-Fi, which requires the caller to be close to the router (ROUTER). * The structure of this technique is based on ITU standards in the global mobile communications programs under IMT-2000 and the user provides large-scale services. 


* The third generation technology is a range of W-CDMA techniques and standards and local wireless areas (English: Cellular Radio), and so on. To be able to connect to the Internet using the third-generation technology, this technique must support the basis, and this technique requires a subscription with service provider. Simple Sim Card is connected. * Data transfer speed The speed of data transfer is ranging from 128 kilobits per second and 384 kilobits per second. It is between 128 kilobia and 144 kbps if the device was If the device holder is walking on foot, it is quickly in maximum, and up to 384 kbps. 


* Technical features by comparing third generation technology with the above techniques, they are characterized by: * 3G technology is much faster in data transfer from previous technologies. Best quality in live broadcasts for audio and video. Possibility to watch TV channels online. The possibility of surfing the Internet at high speeds. 


Fourth Generation Technology: 



* The fourth generation terms (4G) reflects the fourth generation in wireless technology, and was first provided by Sprint (Sprint) at the beginning of 2009, * has become The fourth technical technique is the latest technology than the third generation technology, and is faster than 10 times, and the need for more rapid technology and the tablets and its rapid communication devices, have become able to broadcast videos and audio broadcasts 


* The fourth generation technology is not available to all devices; Where the device used to support data sharing is at least 100 megabytes. Telecommunications companies can provide fourth generation service through long-term development technology (WIMAX), but in both technologies, OFDM technology is used for data packets and sent, as OFDMA technique about label There are many differences between telecommunications companies on the label of the fourth generation technology.


 The term of the fourth generation is used for marketing purposes. It reflects the network that provides high-speed loading speeds, and this is the most important to their customers. Data transfer speeds are different in the fourth generation technology of another company Where the download speed reaches 12 megabytes at Verizon (Verizon), 


which uses long-term development technology to provide 4G service, and speed up to 5 megabytes.


 * As at Sprint, which uses Wimax technology, uploading the download speed to serve the fourth generation to 10 megabytes in second, and speed up 1 megapit in the second.


 Technical Features for the Fourth Generation Many features, including: 



* Support for many broadband services (in English: Live video), in addition to supporting interactive multimedia (in English: in Depends on Internet Protocols (IP). High speed plus large capacity. A few to load the bit (BIT). Supports all known network technologies such as Bluetooth, WCDMA, and 802.11 standards. - Support for older wireless communication systems as 3G technology. Availability of many services dependent on the principle of service quality (QUALITY OF Service). Compared to the third generation and fourth generation if the speed of loading the third generation technology was compared to quickly load the fourth generation, and neglect all the factors that may affect the speed of communication and load, 


the fourth generation technology speed exceeds the speed of the third-generation technique (on imposing that the quality of connection is both in the best Where the download speed is at the fourth generation technology to 1 GB per second. The radio frequencies used in the broadcast of the fourth generation technology range from 2GH and 8GHz, and for the third generation, they range from 1.8GH and 2.5 GHz.
