What VLR Means? Today, let’s talk about VLR, which stands for Visitor Location Register. As we’ve already touched on topics like MME in LTE or Tracking Area in previous discussions, now it makes sense to explore this core component from the 2G and 3G era that still plays a role when networks fall back from … Read more
What is Minimum VSWR? Today, as we continue exploring RF and telecom basics, I want to explain something that plays a big role in antenna systems — the concept of Minimum VSWR, or Voltage Standing Wave Ratio. If you’ve read earlier about antenna matching, you’ve already touched the surface of this. Now, let’s go deeper … Read more
What is BPSK Modulation? Today, let’s explore BPSK modulation. You and I have already touched on LTE signal processing concepts like reference signals and carrier aggregation, and understanding modulation is another key piece. BPSK, or Binary Phase Shift Keying, is one of the simplest digital modulation techniques you’ll come across, and I’ll help you make … Read more
What is Digital Modulation? Today, let’s talk about digital modulation — something that you and I have touched on briefly when we discussed LTE, signal quality, and concepts like QAM or OFDM. To really understand how data is transmitted wirelessly or over any communication channel, digital modulation is one of those foundation blocks you and … Read more
What is VLR in Mobile Computing? Today, let’s explore the concept of VLR, or Visitor Location Register, which is a key element in mobile network operations. We’ve learned about various network elements before, like the Home Location Register (HLR) and the importance of databases in mobile systems. Now, let’s dive into how VLR fits into … Read more
What is TAC and TAI in LTE? Today, we are going to dive into two important concepts in LTE networks: TAC (Tracking Area Code) and TAI (Tracking Area Identity). If you are familiar with some of the earlier topics we discussed, you’ll notice that TAC and TAI play a crucial role in helping the network … Read more
What is a TAC in Networking? Today, let me explain what TAC, or Tracking Area Code, is in networking, especially in the context of LTE and mobile networks. As we learned about network identification and locations in previous articles, understanding TAC helps to identify specific areas within a network that help in the management of … Read more
Is VoLTE Better? Today, we’re diving into an important question: Is VoLTE better than traditional voice services? As we’ve previously explored various communication technologies like LTE and 4G, let me help you understand why VoLTE is a significant improvement over older voice services, and how it impacts your overall mobile experience. So, let’s break it … Read more
What is PUSCH in LTE? Today, we are going to explore PUSCH in LTE. If you’ve read about the concept of uplink communication in previous articles, you might already have a basic understanding of how the data travels from the User Equipment (UE) to the base station. Now, I’ll break down what PUSCH (Physical Uplink … Read more
What is a Good Signal Strength for LTE? Today, let’s dive into the topic of signal strength in LTE, an important aspect of mobile communication that directly impacts the quality of your connection. As we learned in previous articles, signal strength plays a key role in determining how well your device connects to the network, … Read more
