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 […]

There’re many factors that impact the energy consumption in the mobile network operators, some of them related to climate, population density, and data consumption levels, while others are related to the network operators themselves or under its control. So there’re two groups as per GSMA benchmarking: Non-network-related variables – those outside the operator’s control (e.g. […]

The Security Edge Protection Proxy (SEPP) is a proxy that sits at the perimeter of the PLMN network and enables secured communication between inter-PLMN network messages. It protects the home network and acts as a security gateway. Located at the edge of the network, it polices connections between the home network and the visited networks. […]

When it comes to questioning, Are 5G and WiFi6E friends or competitors, I prefer to answer “They Should be Friends” 5G (cellular technology) and Wi-Fi 6E (wireless LAN) use similar technical methodologies to provide high-end user experiences. Both 5G and Wi-Fi 6E are the latest versions of their respective technologies. Two common approaches being used […]

All generations of mobile phone technology, including 5G, take the same familiar underlying approach. A mobile network consists of a nationwide grid of cell sites. These sites feature transmitters that generate radio waves, which are received by a mobile phone’s antenna.  The radio waves generated by mobile networks, TV stations, and radio stations are not […]

As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and layer 2 processing and fulfills critical functions such as coding/decoding, scheduling, MIMO processing, and beamforming. It makes sub-millisecond decisions about allocating radio resources within a […]

5G is an evolving standard. The initial version of 5G was accomplished with the freezing of Release 15 late-drop in summer 2019. Enhanced features originally were introduced in Release 15 and new features were incorporated in Release 16 in 2020. More enhancements of features defined in prior releases and new features are part of Release […]

5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is designed to support a 100x increase in traffic capacity and network efficiency. 5G has lower latency than 4G. 1G, 2G, 3G, and 4G all led […]

3GPP TS 28.541 explains how Yang models are implemented in 5G gNB in gNB-CU and gNB-DU as below: The nrCellDU table models a geographical area of radio coverage that is implemented and supported by physical radio equipment for 5G NR GNB devices, These are contained in GNBDU Functions. Definition NRCELLDU represents the information of a cell […]
