Richard Jhon What is the Symbol in QPSK? Today, we’re going to talk about the symbols used in Quadrature Phase Shift Keying (QPSK). As we previously learned about modulation techniques, QPSK is a type of modulation that helps in efficiently transmitting data over a communication channel. It’s widely used in LTE and other wireless communication systems due … Read more
What is WLAN Setup? Today, let’s dive into understanding what WLAN setup is. As we discussed in earlier articles about wireless networks, WLAN (Wireless Local Area Network) is a network setup that allows devices to connect wirelessly within a limited area, like a home, office, or campus. This setup allows for internet access, file sharing, … Read more
What is an HFC Network? Today, we are going to learn about the HFC (Hybrid Fiber-Coaxial) network, which is a type of broadband network technology commonly used to deliver high-speed internet, television, and voice services. It combines the strengths of fiber-optic and coaxial cable technologies, making it a cost-effective and efficient solution for providing high-speed … Read more
What Causes a Bad RSRQ in LTE? Today, we are going to explore the factors that cause a poor RSRQ (Reference Signal Received Quality) in LTE networks. RSRQ is an essential indicator of the quality of the signal between the User Equipment (UE) and the base station, and it directly impacts the user’s experience, such … Read more
What are HLR and VLR? Today, we’re going to learn about two important concepts in mobile telecommunications: HLR and VLR.
