Why OFDM Use Was Not Popular in the Initial Period? Orthogonal Frequency Division Multiplexing (OFDM) is a widely used method in modern wireless communication systems, including LTE and Wi-Fi. However, it wasn’t always popular in the early stages of wireless communication development. Let’s dive into why OFDM wasn’t embraced initially and how it gained popularity … Read more
Why PSS and SSS in LTE? In LTE networks, PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal) are essential components of the synchronization process that ensures your device can connect efficiently to the network. If you’ve been following our previous discussions on LTE signals, you may already know that synchronization plays a crucial role … Read more
Why is RSRQ Important? In LTE networks, RSRQ (Reference Signal Received Quality) is a critical metric that plays a vital role in ensuring efficient communication. To understand its importance, let’s break down what RSRQ is and how it affects your mobile experience. RSRQ is essentially a measurement used by the network to evaluate the quality … Read more
Why is RSRQ Poor? When you’re using an LTE network, you might have heard of RSRQ, or Reference Signal Received Quality. It’s an essential metric used to assess the quality of your mobile connection. RSRQ helps determine the reliability and strength of the signal you receive from the network. But what happens when RSRQ is … Read more
Why LTE is Called Flat Architecture? Let me walk you through why LTE is often referred to as having a “flat architecture.” Understanding this concept is essential because it highlights how LTE differs from earlier generations of mobile networks, like 2G and 3G, and how it brings improvements in speed, capacity, and latency. In previous … Read more
Why LTE Uses OFDMA for Downlink and SC-FDMA for Uplink? In LTE, you’ll find that the downlink and uplink use different multiple access technologies: **OFDMA** (Orthogonal Frequency Division Multiple Access) for downlink and **SC-FDMA** (Single-Carrier Frequency Division Multiple Access) for uplink. Let me explain the reasons behind this choice in a way that you can … Read more
Why is GTP used in LTE? Let me explain GTP and its significance in LTE networks. If you’ve been following our discussions about LTE, you’ll know that it is a highly complex system that enables fast mobile data, voice services, and more. One of the critical protocols used within LTE networks is GTP, which stands … Read more
Why is it called LTE and not 4G? Let’s dive into why LTE (Long Term Evolution) is often called something other than 4G, despite its widespread association with the fourth generation of mobile networks. If you’ve been following mobile network technologies, you might have noticed that while LTE is often referred to as 4G, technically, … Read more
Why is LTE Called Long Term Evolution? Let me explain why LTE is referred to as “Long Term Evolution” (LTE). As we’ve learned earlier, LTE is the next-generation mobile communication standard after 3G, designed to offer higher speeds and more efficient use of spectrum. The term “Long Term Evolution” has a specific meaning tied to … Read more
Why Does LTE Require IMS? Let’s dive into why LTE networks require IMS, or the IP Multimedia Subsystem, to function effectively. As we know, LTE networks are designed to provide high-speed internet access and enhanced mobile broadband services. However, for services beyond just data transmission, such as voice calls, video calling, and messaging, there needs … Read more
