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 […]

From the perspective of global network coverage, more than 80% of land areas and 95% of sea areas are not covered by ground cellular networks. The 5G network was built not only to provide high network speeds, but also ubiquitous mobile network access. However, in remote areas such as mountainous areas, deserts, and the ocean, […]

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 […]

📗 In 5G SA, NR will enable the service provisioning through gNB (gNodeB) which connects to the new core 5GC (5G Core Network) using NG Interface. 📗 According to GSMA, by 2025, 5G networks will cover a third of the population (measuring 1.8 billion connections) and as per GSA, 116 operators are identified as investing in […]

Mobile communication network sharing refers to the sharing of infrastructure or communication equipment among multiple operators. The infrastructure includes towers, buildings, and equipment rooms used for deploying base stations, whilst the communication equipment includes RAN, transport network, and CN equipment. Network resource sharing includes active sharing and passive sharing. Passive sharing refers to the sharing […]

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 […]

SMS, Short Message Service, is a secure system that helps protect your customers’ and employees’ data and allows you to contact all users who have a mobile phone. 📕 In 2G and 3G, MAP protocols have been defined to support the SMS. MAP interface is built on top of SS7 (TDM or SIGTRAN) using the following layers […]

3GPP consists of three Technical Specifications Groups (TSGs) where TSG RAN (Radio Access Network) is responsible for the definition of functions, requirements, and interfaces of the Radio Access. TSG RAN consists of six working groups (WGs): RAN WG1, dealing with the physical layer specifications. RAN WG2, dealing with the layer 2 and layer 3 radio […]
