LTE : Part 0

LTE is  technology which provides more data speed then 3G and 2G. Also known as 4G.

Unlike 3G, it is only PS network.


Now any user who has used phone uses it mainly for

CALL, SMS , SS , DATA.

Now CALL is mostly CS. And since we were using LTE and it is only PS , we have IMS which provides CALL facility to user.

Now using IMS we can have SMS, and RCS ( RCS is rich communication service (like whatsapp))


So if you have a IMS module and PS connection ( LTE mobile phone, desktop, laptop) you can connect to the outer world easily.

One more important thing is needed, which is SIM , this is simply needed so that OPERATOR can provide us secure service and offcourse they will earn money.


Now in following post we will try to see  how PS connection is provided using LTE. 

Things we will cover will be

1) APN
2) Security
3) Lower Layer working
4) Connection with Network
