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 […]
Energy Usage Resources in Mobile Network Operators (MNOs)
There’re many factors that impact the energy consumption in the mobile network operators, some of them related to climate, population density, and data consumption levels, while others are related to […]
The Role of Hardware Security Module (HSM) in 5G Security?
Security is a driving factor in how 5G networks are built and operated – every element of a 5G network is required to have security controls in place for the […]
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 […]
What is 5G Security Edge Protection Proxy (SEPP)?
The Security Edge Protection Proxy (SEPP) is a proxy that sits at the perimeter of the PLMN network and enables secured communication between inter-PLMN network messages. It protects the home […]
Are 5G and WiFi6E Friends or Competitors?
When it comes to questioning, Are 5G and WiFi6E friends or competitors, I prefer to answer “They Should be Friends” 5G (cellular technology) and Wi-Fi 6E (wireless LAN) use similar […]
The Evolution from 4G to 5G by CPRI to eCPRI Transformation
As per Statista, The number of global unique mobile subscribers is expected to grow by 160 million from 5.7 billion subscribers in 2020 to 5.86 billion in 2025 and this […]
5G is Not Hazardous To Your Health
All generations of mobile phone technology, including 5G, take the same familiar underlying approach. A mobile network consists of a nationwide grid of cell sites. These sites feature transmitters that […]
3GPP Architecture for 5G NR
As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and […]
