The Road to Open RAN is not easy one, there are a series of steps should be taken before migration or starting design the network architecture based on Open RAN. Either you’re a green field needs to start a new network from scratch or even a brown field and re-think of the open RAN concept, […]
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 […]
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 […]
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 […]
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 […]
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 […]
On January 2021, Five big European operators, Deutsche Telekom AG, Orange, Telefónica, Vodafone Group and TIM (which joined in Feb 2021) are signed Memorandum of Understanding (MoU) to provide a framework for a specific commitment to support the development of a non-fragmented global OPEN RAN ecosystem for deployment across the European network footprint of each […]
Recent deployments of 5G widespread use of option 3X as one option in the connectivity scenario background in the infrastructure evolution. As a result, EN-DC, where there are two radio links, E-UTRA, and 5G are offered. To accelerate the introduction of voice services, the major aspect of this method is that NR does not support […]
The Open RAN concept is about building networks using equipment that separates the vendor-specific software and vendor-specific hardware associated with the vast majority of radio access network (RAN) equipment that is available today from a handful of cellular equipment vendors. Open RAN, then, uses RAN software on commercial, off-the-shelf hardware (COTS). There are 9 main […]
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 […]
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 […]
