What is the difference between NodeB and eNodeB? Today, I’ll help you understand the difference between NodeB and eNodeB, and we’ll also relate it to what we previously explored around LTE architecture. If you remember, we’ve already talked about how LTE evolved from UMTS, and that transition directly impacts the shift from NodeB to eNodeB. … Read more
What is 2×2 mu-MIMO? Let me walk you through the idea of 2×2 mu-MIMO in a way that helps you understand it simply and clearly. If you’ve ever heard of MIMO, you might remember it stands for Multiple Input, Multiple Output. Now, when we add “2×2” and “mu-” (which stands for multi-user), we’re getting a … Read more
Is an Antenna Passive or Active? Today, as we continue exploring topics around LTE and network communication, let’s understand the nature of antennas. You’ve probably come across both the terms “passive antenna” and “active antenna,” and it’s completely normal to wonder what makes one different from the other, or which one is typically used in … Read more
What type of antenna to receive DTT? Today, as we explore Digital Terrestrial Television (DTT), it’s important that I help you understand what kind of antenna you really need to receive it properly. Earlier, when we discussed concepts like signal strength, interference, and LTE bands, you might have noticed how essential the right equipment is … Read more
What is Network RSRP? Today, I’ll explain to you what Network RSRP is and how it helps you understand the signal strength in LTE networks. Earlier, when we explored concepts like RSRQ and SINR, you saw how signal quality plays a role. Now let’s focus on RSRP — short for Reference Signal Received Power — … Read more
What is the Point of Having an eSIM? Today, we are going to discuss eSIM and how it benefits you in the world of modern telecommunications. As we learned about traditional SIM cards in earlier discussions, an eSIM is a significant evolution in how mobile networks work. Let me walk you through the concept of … Read more
Is it Worth Converting to eSIM? Today, we are going to explore the idea of converting to eSIM and whether it’s worth it for you. We’ve previously learned about SIM cards and their role in mobile networks. Now, let’s dive into how eSIMs are different and why you might consider switching from a physical SIM … Read more
What is Meant by VSWR? Today, let’s explore the concept of VSWR, which stands for Voltage Standing Wave Ratio. If you’ve worked with RF (radio frequency) systems or wireless communication technologies, you might have heard about VSWR. But what does it actually mean, and why is it important? I’ll walk you through it, step by … Read more
Should You Enable VoLTE? Today, let’s talk about whether you should enable VoLTE (Voice over LTE) on your device. If you’ve been using LTE for data, you might be wondering if it’s worth enabling VoLTE for voice calls. As we discussed earlier, VoLTE is a technology that allows you to make voice calls over the … Read more
Why does VoLTE appear on my phone? Today, let me help you understand why you see the VoLTE icon on your phone screen. If you’ve ever noticed “VoLTE” appearing on your device and wondered what it really means, you’re not alone. Since we’ve already discussed topics like LTE architecture and call handling before, this will … Read more
