Thanks to open standard consortiums such as the ORANAlliance, an open ecosystem of disaggregated and interchangeable components is now available. Network equipment providers are now able to commoditize hardware and […]
Radio Access Network (RAN) is Now Open
What are dApps in ORAN Architecture?
As you may know, there are two main components to RIC or RAN Intelligent Controllers (RICs) as below: Closed-loop control running at time scales of 10ms to 1s (Near-Real-Time, or […]
OpenRAN is NOT O-RAN
Generally speaking, I see many use the same word for different meanings, sometimes they need to refer to O-RAN and write OpenRAN and vice versa. So let’s understand the main […]
What is the “V” in vRAN?
Virtualization is a journey that the telecoms industry has been on for several years to transform network functions into virtual network functions (VNFs). The VNF software is then decoupled from the […]
Why does 5G need to move from CPRI to eCPRI?
5G needs to move from CPRI to eCPRI because eCPRI uses standards-based Ethernet for fronthaul, replacing proprietary CPRI connectivity. This shift enables higher precision timing capabilities essential for vRAN and […]
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 […]
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 […]
