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 […]
What is Flex-5G Project ?
Let’s check the main highlights if you don’t know about this big project. The main focus of this project is creating an End-to-end Open RAN compliant, UK-developed 5G SA network. […]
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 […]
The Road from CPRI to eCPRI/ORAN Fronthual
As we know that RAN, Radio Access Network, is divided into two main components: -> Baseband Unit (BBU). -> Radio Unit (RU). The move from D-RAN to C-RAN then v-RAN […]
What is The Relation between eCPRI, Option 7, Option 7-2x and Split E?
The increase in data rates in 5G makes it impractical to continue with the conventional CPRI fronthaul implementation. Moving towards a higher layer split would relax the latency and bandwidth […]
What is Distributed Unit (DU) in Open RAN?
3GPP defined a new RAN architectural in Release 15, where the gNB (Site Name for 5G) is logically split into three entities denoted as: CU: Centralized Unit. DU: Distributed Unit. […]
Why 5G needs moving from CPRI to eCPRI?
? CPRI is standardized by the Common Public Radio Interface forum with the first specification in 2003 with some features It is based on functional split 8 (Split E in […]
RIC Main Components: Non-RT RIC and Near-RT RIC
The RAN intelligent Controller (RIC) is cloud-native, and a central component of an open and virtualized RAN network. The RIC aligns with 3GPP release 15 and beyond. It is foundational […]
