OFDMA modulation in Mobile Networks
OFDMA (Orthogonal Frequency Division Multiple Access) is a modulation technique used in modern mobile networks, particularly in 4G and 5G. It enables high-speed, high-capacity, and low-latency requirements of modern mobile communications.
OFDMA is a multiple access technique that allows multiple users to share the same frequency band simultaneously.
It works by dividing the available frequency spectrum into multiple narrow-band subcarriers, and allocating them to different users. The subcarriers are designed to be orthogonal to each other, which means they do not interfere with each other, enabling efficient use of the spectrum.
This results in increased spectrum efficiency, improved data rates, and enhanced reliability.

What is 5G CUPS in 5G Network ?
In this post we will learn what is 5G CUPS. CUPS refers to "control plane and user plane separation". 5G CUPS means that the 5G network is separated into "control plane" and "user plane". In order to understand CUPS, first we should know that in order for the UE to be able to exchange user…

5G Core Network Architecture
In this post, we will learn 5G Network Architecture. The control plane in 5G network includes the AMF, the SMF, the AUSF, the UDM, and the PCF. While the user plane includes the UPF. The control plane is not including those network functions only, there are another network functions in the control plane, that will be discussed later. In…

LTE (4G) Network Architecture
LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…
