If you look at how security was addressed in the 4G core (EPC), you had perimeter devices, whether it’s firewalls, security devices that protect from denial of service attacks, or […]
The Security Transition from 4G EPC to 5GC
What is the Importance of Open RAN System Integrator (SI)?
The biggest challenge in transitioning from traditional RAN to Open RAN is the integration of Open RAN components. Guess why! absolutely due to RAN itself getting disaggregated into smaller pieces coming from […]
4 factors To Be Taken Into Consideration When Choosing The Right RAN Functional Split
3GPP defined the functional splits in 38.801 to formalize potential protocol split options. Functional splits are intended to allow functions to run in a central location ( ex. Data Center […]
What is Virtual Cell Site Router (vCSR) ?
An Open RAN (O-RAN) is a nonproprietary implementation of a RAN that allows interoperability between cellular network equipment provided by different vendors. Mobile Network Operators (MNOs) are virtualizing the RAN […]
Open RAN in a few words!
Going from expectations to reality means Open RAN is on the right road to go from reality to expectations. It’ll take some time and needs more cooperation between MNOs and […]

My view for vRAN and OpenRAN Success
vRAN and OpenRAN are not new generations like 4G, 5G, or even 6G. It’s a new way of implementing of access domain in a new way helping at the end […]
Home Subscriber Server in One Page
Home Subscriber Server (HSS) is the main subscriber database used within the IP Multimedia Subsystem (IMS) which provides details of the subscribers to other entities within the network.
Why do we need Accelerator Cards in Open vRAN Solutions?
Open RAN by disaggregation involves CU (Centralized Unit) and DU (Distributed Unit) virtualization. By decoupling hardware and software, Open RAN makes it possible to select different vendors and solutions for […]
2G and 3G Shut down Status – 2023
More pressure now on all MNOs to improve their spectrum utilization and resource efficiency to the maximum to cover all upcoming use cases that need different QoS and requirements. One […]
What is VoLTE Roaming? Architecture Options and Challenges
The 3rd Generation Partnership Project (3GPP) architecture has introduced a subsystem known as the IP Multimedia Subsystem (IMS) as an addition to the Packet-Switched (PS) domain. IMS supports new, IP-based […]
