Market Landscape: RAN Vendors 2024
4G and 5G Electromagnetic Interference with Medical Devices in Hospitals
When I searched for the impact of 4G and 5G frequency spectrum on health/medical sector/hospitals, I found good Japanese research by NTT Docomo about this topic and here I concluded […]
Evolution of Signaling from 2G to 5G
?In 2G and 3G, voice and text were the main services based on SS7 signaling. In these networks service availability was the priority. The Signal Transfer Point (STP) was the […]
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 […]
Can Microwave be a Fronthaul Option for 5G?
First, we need to understand the definition of Fronthaul. Fronthaul is the transmission connection between the Radio Frequency (RF) module and the baseband processing Unit (BBU) in the mobile wireless […]
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 IMSI Catcher?
Before starting to talk about IMSI Catcher, we need to understand what is the IMSI, its importance, and its structure. Based on this, we will discuss the IMSI catcher. So […]
The Security Transition from 4G EPC to 5GC
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 […]
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 […]
