Carrier Aggregation (CA) in Mobile Networks
Carrier Aggregation (CA) is a key technology in 4G and 5G mobile networks. It allows a mobile device to simultaneously use multiple carriers, effectively combining their bandwidth to achieve higher data rates.
The main benefits of Carrier Aggregation include the increased Bandwidth and the improved throughput, which in turn improve user experience.
It can also help improve coverage, as the mobile device can utilise the best available carriers, even if they are on different frequency bands.

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…

Your Guide to LTE Interfaces (S11, S5, S8, SGi, S1-U)
Let's talk about LTE Interfaces. In LTE, every interface between two network nodes, is having an interface name, that represents the protocols used in the communication between those nodes. Below graph shows LTE Interfaces that exist between different nodes, In order to understand LTE Interfaces, we need first to understand the difference between the control…

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…
