Nokia goes further into this OpenRAN game by opening its fronthaul interface with three 3rd party vendors now. Nokia has already integrated third-party TDD RRH from three suppliers with its […]
Nokia Open Fronthaul for Open RAN
Layer 1 Network Functions are The Challengers of vRAN and Open RAN!
When we’re discussing vRAN and Open RAN topics, we’ll find ourselves facing some questions about the performance and cost. The highly common question is ” Can virtualized RAN deliver the […]
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 […]
Open RAN Main Elements
The open radio access network or Open RAN can be broadly divided into the following three elements: Open interfaces that combine RAN equipment from a variety of vendors. Virtualization (i.e., […]
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 […]
Why CPRI is not used in 5G Network?
As I received many messages during the last week about the eCPRI topic in 5G and OpenRAN, I prepared some notes about this. eCPRI is replacing the CPRI protocol in 5G to reduce […]
Why RAN Must Be OPEN?
RAN (Radio Access Network) is the main telecommunication network component that is located between the core network and users’ equipment (such as a mobile phone). RAN is constituted of a […]
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. […]
Time Synchronization is Critical in 5G Open RAN Network
In order to meet the 5G network timing requirements, there is a significant challenge. The challenge is 5G performance requirements driving precise timing needs from cloud to edge. The legacy […]
eNB/gNB Architecture with O-DU and O-RUs
The architecture of eNB or gNB with O-DU and O-RUs has some important definitions here: O-DU: O-RAN Distributed Unit: a logical node hosting RLC/MAC/High-PHY layers based on a lower layer […]
What is Precision Timing Protocol (PTP)?
What is PTP? Precision Time Protocol (PTP), defined in the IEEE1588-2008 standard, is a protocol that uses a master-slave hierarchy to synchronize clocks on network devices. PTP uses hardware time […]
