Introduction to LTE...

LTE stands for Long Term Evolution. It is the evolved version of already present cellular network architecture. In general term people call it 4G also. But in fact it is NOT a 4G technology standard, it's a 3.9G. LTE-Advance is the actual 4G technology standard.

Before going further in to the brain storming architecture and call flows, we should first know the history and evolution of LTE to keep interest in it.

So the evolution of a cellular network is as follows in the diagram. As I am too lazy to draw a complete diagram, I have pulled an image of Rohde & Scewarz :

So, There are several organizations who work for cellular network architect such as 3GPP, 3GPP2, IEEE. LTE standard is defined by 3GPP. So anything you read, implement or use for LTE, it should be as per 3GPP standards.

 As we are going forward day by day, we see that there are more data hungry applications. LTE will resolve this issue. In the next post we will read the motivation behind the LTE standard, the Goal set for LTE and how much LTE will be succeeded in satisfying data hungry application.

Hello World by Core LTE...

Hello everyone.

Welcome to Core LTE. This blog is dedicated to all the engineers, managers and whoever directly or indirectly working for LTE.

In this blog I will post LTE related articles. LTE is a 3GPP standard specification. I will just try to explain what 3GPP wants to say about LTE in my own words. As no one knows everything, I am also here to learn from my reader. If you find any error or conflict which seems not aligned with 3GPP standards, please inform me. I'll fix it right away.

I will try my best to explain things clearly and everything what I know or found on LTE.

About me:
I am Shekhar Prasad Shaw. I am working in LTE since last about 2.5 Years in Qualcomm as a contract employee. I am a ECE branch student, passed out in 2012 from WBUT.

I thank everyone who visited my blog, read my posts and I'll appreciate if your give your valuable feedback and comments of my posts. Thanks for reading and please share this to your LTE colleagues also. :)

Thanks you very much.
