What Does FTTx Mean? Today, let’s talk about FTTx, a term you may have encountered when discussing broadband internet connections. FTTx stands for “Fiber to the x,” where “x” represents different points in the network. Essentially, it’s a family of broadband network architectures that use optical fiber to deliver high-speed internet access. Let me explain … Read more
How Do WebSockets Work? Today, we’re going to dive into WebSockets and understand how they work. In previous articles, we’ve talked about HTTP and how it enables communication between clients and servers. Now, let’s look at WebSockets, which provide a more efficient way for real-time, two-way communication between a client (like a web browser) and … Read more
What is the Cause of High BLER in LTE? Today, let’s talk about BLER, which stands for Block Error Rate. It’s an important metric in LTE that indicates the ratio of incorrectly received blocks to the total number of transmitted blocks. A high BLER means that more data blocks are being received incorrectly, which leads … Read more
What Are QCI Levels in LTE? Today, we will talk about QCI (Quality of Service Class Identifier) levels in LTE. As we learned in previous articles, QoS (Quality of Service) plays a significant role in ensuring that users get the appropriate experience for their network activities. QCI levels help define how different types of data … Read more
What is Node B? Today, let’s talk about Node B, a critical component in the UMTS (Universal Mobile Telecommunications System) network. As we discussed earlier about the architecture of mobile networks, Node B plays a central role in the radio access network (RAN) of 3G. Let me explain to you how it works and why … Read more
What is the Advantage of WebSocket? Today, we are going to dive into understanding WebSocket and the advantages it brings to real-time communication. If you’ve been following along, we’ve already discussed some key aspects of network communication protocols. Now, let’s explore how WebSocket differs from traditional HTTP-based protocols and why it’s so useful, especially for … Read more
