What is LTE? 

LTE Stands for Long Term Evolution. LTE is a 4G wireless broadband. LTE network is designed to provide up to 10x the speeds of 3G networks. LTE is developed by the Third Generation Partnership Project (3GPP). LTE helps to improve speed of 3G networks for mobile devices such as smartphones, tablets, netbooks, notebooks and wireless hotspots. LTE Speed acts as a standard for wireless communication for data terminals and mobile phones to support high speed data. LTE projects is purely based on EDGE/GSM and HSPA/UMTS or mobile network technologies. An acronym for 3^rd generation partnership project is 3GPP. it operates and carries out its function under European Telecommunications standard Institute. LTE projects are a natural upgrade way for carries with both GSM/UMTS networks and CDMA 2000 networks. It is also known as LTE super 3G known LTE Super 4G

What is 4G?

The International Telecommunications Union-Radio (ITU-R) is the United Nations official agency for all manner of information and communication technologies, which decided on the specifications for the 4G standard in March 2008.
It decided that the peak download speeds for 4G should be 100Mbit/s for high mobility devices, such as when you're using a phone in a car or on a train.
When you're stationary, (low-mobility local wireless access) it decided that 4G should be able to deliver speeds up to around 1Gbit/s.
If true 4G is supposed to offer us download speeds of up to 1Gbit/s, then why are we getting 100x less in the UK, at around 10-12Mbit/s in real-world speeds?

What is LTE?
3GPP engineers named the technology "Long Term Evolution" because it represents the next step (4G) in a progression from GSM, a 2G standard, to UMTS, the 3G technologies based upon GSM. LTE provides significantly increased peak data rates, with the potential for 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing GSM and UMTS technology. Future developments to could yield peak throughput on the order of 300 Mbps.
The upper layers of LTE are based uLTE is scheduled to be launched commercially in 2010 by Verizon Wireless and AT&T Wireless. T-Mobile and Alltel have also announced plans to roll out 4G capabilities based on LTE. These networks will compete with Clearwire's WiMAX for both enterprise and consumer broadband wireless customers. Outside of the US telecommunications market, GSM is the dominant mobile standard, with more than 80% of the world's cellular phone users. As a result, HSDPA and then LTE are the likely wireless broadband technologies of choice for most users. Nortel and other infrastructure vendors are focusing significant research and development efforts on the creation of LTE base stations to meet the expected demand. When implemented, LTE has the potential to bring pervasive computing to a global audience, with a wire-like experience for mobile users everywhere.pon TCP/IP, which will likely result in an all-IP network similar to the current state of wired communications. LTE will support mixed data, voice, video and messaging traffic. LTE uses OFDM (Orthogonal Frequency Division Multiplexing) and, in later releases, MIMO (Multiple Input Multiple Output) antenna technology similar to that used in the IEEE 802.11n wireless local area network (WLAN) standard. The higher signal to noise ratio (SNR) at the receiver enabled by MIMO, along with OFDM, provides improved coverage and throughput, especially in dense urban areas.

What is 4G VoLTE?

The VoLTE on the other hand stands for Voice Over LTE. It means that unlike the 4G LTE, even the calls, SMS and web browsing will be served through the 4G VoLTE technology. Saying so, you’ll be using the Internet data plan to make calls, send SMS or browse the web all together.

What are the Benefits of using 4G VoLTE over 4G LTE?

There are a variety of reasons why using the latest VoLTE technology over the LTE is beneficial. Below a few popular reasons.

• High quality voice calls
• High definition video calls
• Better battery life
• Quick call connection
• Increased VoIP functionality
• Instant switching between voice and video calls  

What’s the Difference between 4G LTE and 4G VoLTE?

With 4G LTE, one can use the data (Internet) to surf the web, use the apps that require Internet connection etc…All the calls and SMS services will be carried through either 2G or 3G network.
Fortunately, the VoLTE or Voice Over LTE, as the name suggests, handles all the services like browsing, voice calls, SMS etc…through the data/Internet. This enables you to make HD voice calls over the web (similar to the WhatsApp voice calling, which make calls over the IP network).\
However, the only disadvantage is that when you’re travelling to remote places in India where there is no reliable 4G network, you’ll be switched back to the 2G/3G network (whichever is available).
