Richard Jhon How Does Full Duplex Work? Today, we’re going to discuss full duplex, a communication system that allows data to flow in both directions simultaneously. As we’ve explored various communication systems in the past, such as half-duplex and simplex, it’s important to understand the distinction between these and full duplex. In simple terms, full duplex communication … Read more
What are the Differences Between HLR and VLR? Today, let’s dive into a key aspect of mobile communication networks. In previous articles, we learned about the roles of databases in mobile networks. Now, we will focus on two essential elements: the Home Location Register (HLR) and the Visitor Location Register (VLR). These two databases play … Read more
What Does O-RAN Mean? Today, let’s talk about O-RAN, which stands for Open Radio Access Network. O-RAN is a concept that has gained a lot of attention in the telecommunications industry due to its potential to revolutionize how radio access networks (RAN) are built and operated. It focuses on making the network more flexible, interoperable, … Read more
What is VLR in LTE? Today, we are going to learn about VLR, which stands for Visitor Location Register. It plays a crucial role in managing mobile network subscribers’ information in a cellular network. Let me explain it in a way that makes it easier for you to understand. In previous discussions, we covered the … Read more
What is Broadcasting on 450 MHz? Today, we are going to explore the concept of broadcasting on the 450 MHz frequency band.

What is MCC MNC for? Today, let’s dive into understanding what MCC (Mobile Country Code) and MNC (Mobile Network Code) are, and why they’re important in mobile communication networks like LTE. As we discussed earlier in related articles, mobile networks have several identifiers and codes that help manage and route data efficiently. Now, we’re focusing … Read more
Is Mobile Internet Safe? Today, let’s talk about mobile internet safety and what you can do to ensure that you’re browsing securely on your mobile device. As we’ve seen with the increasing use of mobile networks for everyday activities like shopping, banking, and social networking, mobile internet security has become a major concern for many … Read more
What Does SINR Mean? Today, let’s dive into understanding what SINR means in the context of LTE networks. You might have heard about SINR when discussing signal quality or network performance. SINR stands for Signal-to-Interference-plus-Noise Ratio. It’s an important metric that tells us how strong the desired signal is compared to the interference and noise … Read more
What is QPSK? Today, let me explain to you about QPSK, which stands for Quadrature Phase Shift Keying. We’ve already learned about modulation techniques in LTE, and QPSK is one of the most common techniques used in wireless communication systems like LTE. It’s a form of phase modulation where data is encoded by changing the … Read more
What is an eNodeB Modem? Today, we’re going to explore the concept of an eNodeB modem in LTE networks. As we previously discussed the LTE architecture and its components, you might remember that eNodeB (evolved Node B) is a critical part of the LTE infrastructure. It’s responsible for handling radio communications between the User Equipment … Read more
