LTE TECHNOLOGY

LTE Technology (Long-Term Evolution), also marketed as 4G LTE, is a high-speed wireless data transmission standard based on GSM/EDGE and UMTS/HSPA network technologies. It was proposed in 2004 by NTT DoCoMo in Japan. Initial work started in 2005. A preview version of LTE/SAE was developed in May 2007. In December 2009, the first modem was announced by TeliaSonera.

Development started within the scope of 3GPP. The LTE interface supports 2G and 3G communication. The connection speed is 300 Mbit/s on cell phones. The LTE standard was set in March 2011. In 2012, CDMA operators planned to switch to LTE and services were launched in 2013.

4G, which combines network service anywhere at any time at a single point, is used with all IP-based terminals, wired or wireless computers, communication technologies that can be used indoors and outdoors. It is the only system that can provide 100 Mbit/s to 1 Gbit/s data transmission capacity. There are LTE Advanced and LTE Advanced Pro types.

LTE-Advanced is a technology based on the 4G LTE system. Operators have touted this system as 4.5G, but LTE-Advanced is a 4G system. LTE-Advanced differs from LTE in that speeds of 300/450 Mbps can be achieved by combining multiple separate carriers.

LTE Advanced Pro (LTE-A Pro, 4.5G, 4.5G Pro, 4.9G, Pre-5G, 5G Project) is the name of 3GPP version 13 and 14. It is the next generation cellular standard following LTE and LTE Advanced (LTE-A) and supports data rates in excess of 3 Gbit/sec using 32 carriers combined. In addition, it includes several new technologies. 256-QAM, Massive MIMO, LTE-Unlicensed and LTE IoT, which are associated with 5G and have been developed to support the 5G standard.

Below is the table difference between LTE Advanced and LTE Advanced Pro;

Features LTE Advanced LTE Advanced PRO
3GPP Standard Edition 3GPP Release 10, 11, 12 3GPP Release 13 and later
Total Carrier Bandwidth 100 MHz, 5 carriers of 20 MHz each 640 MHz, aggregates up to 32 carriers of 20 MHz each
Data speed 1Gps More than 3 Gbps
Latency 10 ms Less than 2 ms
Communication devices are required for emergency communication in public safety and public services. In addition to voice planning in these communication devices, users want to not only hear each other, but also see each other clearly. With the development of LTE technology, its most important features such as low latency and high bandwidth have made great changes in the way we communicate. LTE technology has now entered the field of private communication. It is the choice of users who have needs such as transferring large data and videos.
