How Does International Roaming Billing Work? Wholesale/Retail
September 29, 2024

When going to the Roaming topic, sometimes you hear words like Wholesale Charge and Retail Charge. So What is the difference between them? The Wholesale Charge determines how much roaming costs a mobile operator. Here, mobile operators negotiate roaming agreements with their counterparts in other countries. Under these agreements, a mobile operator pays the foreign operator […]

Evolution of Signaling from 2G to 5G
June 9, 2024

📃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 node that routed signaling messages. 📃In 4G, networks became data and media-centric and needed signaling to support smartphones and Apps. Signaling volume grew to support […]

The Convergence between Mobile Technologies and Wi-Fi
May 28, 2024

In 2021, I wrote this article about 5G and Wifi 6 convergence, and then in 2023, I addressed this big question: Are 5G and WiFi6E Friends or Competitors?  Conclusion of these articles if you don’t have time to read them as below: 📗The integration of 5G and Wi-Fi is poised to become more ubiquitous. Using […]

OpenRAN is NOT O-RAN
May 26, 2024

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 difference between them as below: Why Do We Need O-RAN? The strong push for Future RANs to be built on a foundation of virtualized network […]

What is the “V” in vRAN?
May 19, 2024

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 purpose-built hardware and run on standardized, common off-the-shelf (COTS) hardware. The interfaces between each component in such a setup may still be closed or proprietary. […]

Can Microwave be a Fronthaul Option for 5G?
May 12, 2024

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 network.  In the traditional distributed RAN or D-RAN, the fronthaul distance is short as the RF module and BBU are directly connected via optical fibers. […]

Why does 5G need to move from CPRI to eCPRI?
May 4, 2024

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 openRAN deployments on general-purpose server hardware, making the network more flexible and cost-effective. Why 5G needs moving from CPRI to eCPRI? eCPRI enhances 5G networks […]

What is IMSI Catcher?
March 24, 2024

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 let’s GO 🙂  What is IMSI? IMSI, International Mobile Subscriber Identity, is a unique static identity allocated to each subscriber in a mobile wireless system. […]

The Security Transition from 4G EPC to 5GC
March 19, 2024

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 just security gateways at the periphery, and you had fewer vendors addressing the core infrastructure. So, if you have a single core vendor, the risk […]

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 different vendors (multi-interoperability) in different layers (Horizontal and Vertical) from Control, User to Management. Below is the conclusion, I quoted from Tietoevry’s white paper about […]

4 factors To Be Taken Into Consideration When Choosing The Right RAN Functional Split
March 15, 2024

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 ) Vs. distributed in the radio heads ( ex Site Location). There are 4 factors to be taken into consideration when choosing the right functional […]

What is Virtual Cell Site Router (vCSR) ?
March 5, 2024

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 to achieve cloud-like agility and economics. As per statistics, The virtualization of the RAN network is expected to grow at a 19% CAGR (compound annual […]

Open RAN in a few words!
March 4, 2024

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 OpenRAN vendors.  Open RAN is about choosing the optimal product from a variety of products that meet specifications for each function -> Meaning avoiding Vendor […]
