What is LTE-Advanced?

Long-term Evolution Advanced (LTE-Advanced) is a wireless communication technology to convert higher data speeds into mobile phones and other devices. This is a revised version of LTE updated to be fully compatible with the family of the fourth generation wireless standards or 4G. LTE-Advanced uses some sophisticated techniques to bring speed up to gigabit per second end users, while maintaining compatibility with older systems.

various wireless and cell phone technologies are often grouped into generations: early analog networks were the first generation or "1G" technology; The first digital network was part of the second generation known as "2G;" And more modern networks with higher data speeds were considered "3G". While wireless service providers often use these labels for marketing purposes, they are really roofing terms that can cover a wide range of technologies.

lte-advanced is a revision that hasbring to FU earlier Ltell technology compliance with the fourth generation or "4G" family of wireless technology, as defined in the sector of the radiocommunication sector of the International Telecommunications Union (ITU-R). The 4G ITU-R specification, which formally refers to international mobile phone calls, requires the theoretical maximum data speed of 100 megabits per second (MBPS) in situations with high mobility or 1 gigabit per second (GBP) in fixed or low mobility. Early revisions of LTE and Wimax®, although some carriers are offered as 4G, do not meet the requirements of IMT-Advanced and are more appropriately called the technologies "pre-4G" or "3.9G".

In order to achieve higher data speed while maintaining compatibility with older LTE standards, LTE-Advanced designers had to use some relatively advanced techniques. A larger amount of radiofrequency spectrum may be usedThose to grow to new techniques for more efficient use of limited spectrum. A new technology compatible devices are likely to contain a number of antenna fields, and a process called beam can turn future interference into a signal increase.

Using a diagram known as the agrement of the carrier, the cell base station can divide the data current and transmit it using multiple radio frequencies to the user's device, which then re -assembles these multiple pieces to the original data current. Another technique known as a coordinated multi -point transmission/income uses several basic stations for sending and receiving data to one device. This may be particularly advantageous for customers who are on the edge of the area of ​​coverage of a particular station; By combining two basic stations, you can achieve faster and more reliable connection. In the relay you can even use multiple basic LTE-advanced.ext stations.
