In the high-level network architecture, the RAN is represented as a single functional entity whereas in reality the realization of a 5G RAN is not so straightforward. In GSM/GPRS and […]
Functional Decomposition of the 5G RAN “Split Architecture”
Four Satellite “Sweet Spots” in the 5G Ecosystem
For mobile operators, 5G is far more than a faster version of the 4G/LTE standard. 5G will be an entirely new networking architecture — “a network of networks” — with […]
Voice Service in 5G Network (VoNR, EPSFB)
Although the request for data services is the primary driver behind the growth and evolution of 5G, voice service is still an indispensable part of mobile communication network. The Voice […]
Why EAP Protocol is used in 5G Security?
The authentication procedure in 3GPP 5G security has been designed as a framework to support the Extensible Authentication Protocol (EAP) – a security protocol specified by the Internet Engineering Task […]
META is not only for Facebook Name, It’s also for Telecom

Evolving RAN Architecture to Open RAN
Open RAN has gained prominence in the last few years due to ongoing trends towards openness and disaggregation in the mobile network operator (MNO) space and spurred by recent geopolitical […]
What is The Importance of Network Slicing?
As 5G supports different types of use cases from eMBB, URLLC, and MTCs. These services require strict SLA (Service Level Agreements) which requires a dedicated end-to-end channel for each service. […]
The Difference between SIBs in 4G and 5G
As you may know that UE can access the network if it can receive some of the System Information (SI) from the Cell (Mandatory). So Let’s understand the main difference […]
Why Do We Need a New OSS/Orchestration in Open RAN?
Open RAN is a highly disruptive technology that will bring many benefits to Mobile Network Operators (MNOs), especially during the evolution to 5G. By opening up the RAN to multiple […]
What is the difference between EPC,EPC+ and 5GC?
The core network is the most important domain in the mobile network starting from 2G and 3G while the MSC and SGSN are the main functions there to EPC or […]
5G Security Vs. 4G Security
5G Timeline and Standardization During preparation, it was decided to split Phase 1 into two parts. In December 2017, standardization of the non-autonomous, or Non-Standalone, architecture for 5G New Radio […]
