Long Term Evolution (LTE) is the latest high speed 4G technology introduced in 2010 by AT & This standard is developed by 3GPP and is specified in its release 8 series. Its architecture is based on Internet Protocol (IP) packet switched network. It is mainly used for data. There are many procedures to make a voice call:

1) Voice over LTE (Based on IP Multimedia Subsystem)

2) Circuit switched fallback (Fallback to circuit switched domain at calling time) 3) Simultaneous voice and LTE (simultaneously changes in circuit switched mode at calling time and LTE mode providing data services)

LTE is the best technology from 1G, 2G and 3G.First generation (1G) introduced in 1980 was based on analog technology. In it, signal is modulated to higher frequency, approximately 150 MHz and up. Its speed is so less.

To overcome the drawback of 1G, 2G came into picture in 1991 based on digital technique.2G technologies can be divided into TDMA (Time Division Multiple Access) based and CDMA (Code Division Multiple Access) based depending upon the type of multiplexing used. The main 2G standards are GSM, IS-95, PDC, D-AMPS and IS-136.The main disadvantage was that some digital signals may be weaker enough to reach the cell tower. Its data rate is less.

To increase its speed, 2.5G i.e. GPRS (General Packet Radio Service) came into existence. It has packet switched domain with circuit switched domain. It provides data rate of 56 kbps to 115 kbps. It can be used for services like WAP(Wireless Application Protocol),MMS(Multimedia Messaging Service) and internet communication services like email, www access etc. GPRS data transfer is charged in megabyte of traffic transferred while data communication via circuit switching is billed per minute of connection time whether the user is utilizing it or in idle state.

To increase the capacity, 2.75G i.e. EDGE (Enhanced Data Rate for GSM Evolution) came into picture. In it, 8PSK encoding is used. It has maximum 250 kbps speed.

After 2.75G, the technology moved to 3G. It was introduced in 2000.It offers faster data transmission speeds, greater network capacity and more advanced network services. Using 3G, we get the minimum speed of 2mbps for stationary mobile and 384 kbps for moving. It is known as “Mobile Broadband Technology” because using it; we can get the divergent data transfer rate. It uses packet switching for data transmission. It uses turbo codes for error correction.3G technologies are CDMA2000, UMTS etc. The frequency band used in 3G is 1.5-2.8 GHz. In it, peak upload rate is 5 Mbps and download rate is 100 Mbps. In it, video conferencing and other high quality services can be used. But wider bandwidth was not available in it.

Now data transmission is becoming more and more popular than voice calls. After 3G, 4G is specially designed for data transmission rather than voice. LTE is 4G technology with WiMAX introduced in 2010 .LTE is termed as “MAGIC-Mobile multimedia, anytime anywhere, Global mobility support, and customized personal service”. LTE supports peak download rate of 1 Gbps and upload rate of 500 Mbps. It uses packet switching and message switching.

LTE (Long Term Evolution) is the newest data transmission technology that is becoming immensely popular today due to several benefits that it offers. It provides high peak data rates, high spectral efficiency, frequency flexibility and short round trip time. It is a 4G networking technology which ensures that permanence of competitiveness of 3G network systems in future.

It is an incredible technology that provides much higher data rates and astonishing quality of service over a packet switched optimized system. LTE is a networking technology that is based on Orthogonal Frequency Division Multiple Access (OFDMA) which makes it possible to reach higher data volumes and data rates. Not only this, but LTE also provides very high order modulation of up to 64 QAM, MIMO transmission in the downlink and large bandwidth of 20 MHz. Since LTE provides such higher data rates & spectral efficiency, and also implements an architecture which is flexible to access, LTE is gaining huge popularity among the network operators and the customers. Thus as we are moving into this newer wireless broadband technology, it becomes quite essential for technology professionals working in the telecom & networking field to understand the fundamentals and unique nature of this technology.

Therefore, LTE Training becomes essential for proper implementation, usage and troubleshooting of this technology. LTE Training presents a perfect blend of evolving market drifts, new information and future goals etc. like the vision of a throughput of 1 Gb/sec with advanced LTE.

We have been providing world class LTE training for experienced and inexperienced aspirants. We provide LTE Training with the goal of making intricate technology fundamentals as simplified as possible so that learners can easily understand these. The LTE training that we offer provides a profound understanding of SAE/ LTE signaling networks, protocols and architectures to the learners. On the completion of this training course, the learners would become well versed with E-UTRAN, evolved 3GPP architecture and LTE air interface. There are several LTE training programs which focus on different aspects of LTE and differ in duration on the basis of that.

Learners can choose from LTE RAN signaling training, LTE RF Planning Training which covers RF planning, designing and optimization, LTE security training which covers security aspects of LTE and LTE advanced, LTE self optimizing and self organizing networks training etc.
