What is the function of OFDMA? Today, let’s talk about OFDMA and how it actually functions within LTE. As you might remember from our earlier discussions on LTE access techniques, we’ve already come across the concept of multiple access methods. Now, it’s time to look specifically at Orthogonal Frequency Division Multiple Access (OFDMA), which is … Read more

Why do I keep getting emails from McAfee? Today, let’s look into something that might have been bothering you — those constant emails from McAfee. If you’ve been receiving them frequently, even though you may not have signed up or you’re no longer using their services, there are a few specific reasons behind this. And … Read more

What is One of the Differences Between OFDMA and FDMA? Today, we are going to dive into one of the key differences between two important multiple access techniques used in communication systems: OFDMA (Orthogonal Frequency Division Multiple Access) and FDMA (Frequency Division Multiple Access). If you’ve been following our earlier discussions, you might already know … Read more

What do you mean by HSDPA? Today, let’s explore something that builds on what we’ve previously discussed around 3G technologies — HSDPA. If you remember our earlier conversations around WCDMA and the evolution of mobile networks, this will fit right in and give you a clearer view of how mobile internet got faster over time. … Read more

What is HSPA? Today, let’s understand HSPA, and along the way, I’ll connect it with other technologies we’ve talked about like LTE and UMTS so that you can place it clearly in your mind. HSPA stands for High-Speed Packet Access, and it’s a mobile broadband technology used to enhance 3G (UMTS) networks by improving data … Read more

How do I find MCC and MNC? Today, as we explore how to find the Mobile Country Code (MCC) and Mobile Network Code (MNC), I want to help you clearly understand what these codes are and where you can find them. If you remember, in one of our earlier topics, we talked about how LTE … Read more

What is HSS in Communication? Today, as we explore more about the LTE core network, I want to explain something that plays a central role in managing user identities and subscriptions — and that’s the HSS, or Home Subscriber Server. If you’ve already gone through topics like MME or EPC, you’ll see how this one … Read more

What does HSS do? Today, let’s dive into the role of the HSS – the Home Subscriber Server – in an LTE network. Since we’ve previously talked about elements like the MME and SGW, it’s a good time to understand how HSS fits into the big picture and how it interacts with these nodes to … Read more
