LTE Unacknowledged Mode (UM) RLC PDU overview is discussed in another tutorial. If you want to learn the basics of UM data PDUs you can check the following tutorial. LTE RLC PDU Structure & Encoding In this tutorial examples for most important encoding techniques used for UM RLC PDUs are discussed. UMD PDU with 5 bit SN (No LI) Assumptions (more ..)
There are two different types of MAC HSDPA PDU format depending upon the upper layer configuration. MAC-hs MAC-ehs In this tutorial only MAC-ehs is covered. In this case the MAC HSDPA PDU is consists of MAC-ehs header One or more reordering PDUs Each reordering PDU consists of one or more reordering SDU belonging to the same priority queue. Header Elements (more ..)
The STATUS PDU is used to exchange status information between two RLC AM entities.
In this tutorial following topics are discussed:
The security architecture in UMTS is divided into four main parts:
In this tutorial User identity confidentiality is covered.
In this tutorial, we will discuss the overview of LTE Tracking Area update and then discuss in details the end-to-end call flow signalling procedure. Before we begin, let’s check what is a Tracking Area in LTE network. LTE Tracking Area The tracking area is similar to Location Area and Routing area in UMTS, which is basically a geographical combination of (more ..)
The last generation of mobile communication was all about higher bit-rate to deal will massive mobile broadband. 5G as a technology will not only focus on high-bit rate but at the same time, it will have goals towards low bit-rate devices and sensors for IoT applications.
I was a tester for a long time and I was asked the following question from time to time. What is the best country to work as a LTE tester? In which country I can use my competence to get better compensation and live a better life.
