Fixed Wireless Access (FWA), a wireless link that provides connectivity to objects that are stationary or nomadic, will receive a boost thanks to improved 5G capabilities. The first 5G use case we highlight is FWA. The demand for high-speed broadband connectivity continues to grow exponentially, driven by the increasing reliance on digital technologies and the […]

The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make […]

My telecom journey started 13 years ago in the access domain which more specifically we can call it RAN or Radio Access Network which mainly focuses is more towards Air interfaces including spectrum, RF elements, site components, RAN features, interfaces, protocols, …etc. However, in the last 7 years, I have seen a huge shift from […]

The fact of Sustainability in mobile networks starts with power reduction and meeting net-zero goals, and as we know wireless networks consume large amounts of resources, from electricity to raw materials. 📃 GSMA Intelligence published a report looking at network energy efficiency. It found that the RAN consumes 73% of the energy network operators use. 📃 Also, […]

5G has made it possible for wireless networks to compete against fiber, satellite, xDSL, and cable in delivering high-speed broadband service to residences and businesses at attractive prices through FWA. What is FWA? Fixed Wireless Access (FWA) is a method of connecting subscribers to broadband Internet access using a wireless alternative to traditional copper cables and/or fiber. How does 5G […]

5G defines the use of wide radio channels. Whereas 4G is limited to a maximum radio channel size of 20 MHz, 5G standards specify the use of radio channels up to 100 MHz in frequency bands below 7 GHz and up to 400 MHz in mmWave radio channels at 24 GHz and higher. Beyond these […]

5G delivers higher data speeds, and lower latency, and supports more users, devices, and services while simultaneously improving network efficiency. As defined by the Third-Generation Partnership Project (3GPP), the 5G core (5GC) network is a cloud-aligned, service-based architecture (SBA) and covers all 5G functions and interactions. The converged 5GC lays the foundation for a single […]

📕 5G network comprises a remote radio unit (RRU), distributed unit (DU), a centralized unit (CU), and a core network. The terms fronthaul, midhaul, and backhaul are describing the 5G transport network support for the interfaces between these nodes. 📕 A Fronthaul transport network supports the low-layer functional split point of 3GPP NG-RAN (e.g., Option […]

As we know that RAN, Radio Access Network, is divided into two main components: -> Baseband Unit (BBU). -> Radio Unit (RU). The move from D-RAN to C-RAN then v-RAN and O-RAN depends on how to deploy these two RAN components. MNOs want to #centralize the RAN control functions to improve overall performance, gain efficiencies, and reduce […]

All notes you should know about 5G mmWave Band. 🔋 5G mmWave refers to the higher range of radio frequencies (above about 24 GHz) supported by 5G. Also, it’s called FR2 or Frequency Range 2. 🔋 5G mmWave provides a significant capacity increase with an additional spectrum. 🔋 5G mmWave FR2 Frequency rand is FR2-1 […]

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 requirements, but then fewer processing functions can be centralized. It is thus critical that the new functional-split architecture takes into account technical and cost-effective trade-offs […]
