How 5G Drives Technical Efficiency Gains
July 24, 2022

5G builds upon existing network infrastructure to handle the increased demand for data in an interconnected society. It is transforming industries and is changing the way businesses and consumers use mobile technologies, providing substantial processing and efficiency benefits that previous generations of mobile technology did not. 5G can deliver up to 100 times higher bandwidth, […]

Why is C-Band Spectrum Important for 5G?
March 6, 2022

Not all radio spectrums are equal. Sub 1GHz offers the best coverage profile; however, the amount of low band spectrum available is limited. Frequency range two (FR2), i.e. greater than 6GHz, offers a large amount of spectrum with a significantly wide bandwidth (up to 400MHz), but it offers limited coverage. In fact, it is an […]

Functional Decomposition of the 5G RAN “Split Architecture”
December 10, 2021

In the high-level network architecture, the RAN is represented as a single functional entity whereas in reality the realization of a 5G RAN is not so straightforward. In GSM/GPRS and UMTS there was a network controller [BSC and RNC] which provided an interface between the radio access network and the core network. This network controller […]

Four Satellite “Sweet Spots” in the 5G Ecosystem
November 22, 2021

For mobile operators, 5G is far more than a faster version of the 4G/LTE standard. 5G will be an entirely new networking architecture — “a network of networks” — with multiple access technologies such as Wi-Fi, small cells, and traditional mobile wireless networks as well as terrestrial and satellite. Satellites will play a vital role […]

Voice Service in 5G Network (VoNR, EPSFB)
November 10, 2021

Although the request for data services is the primary driver behind the growth and evolution of 5G, voice service is still an indispensable part of mobile communication network. The Voice over New Radio (VoNR) feature provided in 5G is similar to VoLTE in 4G. VoNR is a voice solution based on IMS in 5G SA […]

Why EAP Protocol is used in 5G Security?
November 9, 2021

The authentication procedure in 3GPP 5G security has been designed as a framework to support the Extensible Authentication Protocol (EAP) – a security protocol specified by the Internet Engineering Task Force (IETF) organization. This protocol is well established and widely used in IT environments. The advantage of this protocol is that it allows the use […]

META is not only for Facebook Name, It’s also for Telecom
October 29, 2021

The first thing that came to my mind when Facebook CEO Mark announced to change the name of his mega applications (Facebook, WhatsApp, Messenger, Instagram, .. etc) to META or Metaverse technology, is METASURFACE. What is Metamaterial? The prefix meta (a Greek word meaning ‘beyond’) indicates that the characteristics of the material are beyond what we […]

Evolving RAN Architecture to Open RAN
October 27, 2021

Open RAN has gained prominence in the last few years due to ongoing trends towards openness and disaggregation in the mobile network operator (MNO) space and spurred by recent geopolitical pressures. The below explanation is part of Unlocking Open RAN — An Infrastructure Viewpoint white paper. Evolving RAN Architecture to Open RAN Over the different […]

What is The Importance of Network Slicing?
October 9, 2021

As 5G supports different types of use cases from eMBB, URLLC, and MTCs. These services require strict SLA (Service Level Agreements) which requires a dedicated end-to-end channel for each service. Exciting networks are not equipped or scalable enough to support such demands, So the solution to realize the full extend of 5G performance is Network […]

The Difference between SIBs in 4G and 5G
October 8, 2021

As you may know that UE can access the network if it can receive some of the System Information (SI) from the Cell (Mandatory). So Let’s understand the main difference between SIBs in 4G and 5G NR. 🧧 Difference Number 1 LTE MIB, SIB1, and SIB2 are mandatory for the UE to access a cell […]

Why Do We Need a New OSS/Orchestration in Open RAN?
August 8, 2021

Open RAN is a highly disruptive technology that will bring many benefits to Mobile Network Operators (MNOs), especially during the evolution to 5G. By opening up the RAN to multiple vendors and virtualizing the software, costs will be significantly reduced, highly dynamic services will be enabled, and the RAN domain will experience far greater levels […]
