There are different Open vRAN deployment models, bring clear flexibility and adaptability to networks, so that different use case requirements can be addressed dynamically and provide a more efficient and rapid response to business requirements. The 3GPP model for 5G architecture relying on Open interfaces together with RAN virtualization, allows an optimized deployment of DU/CU, […]

LTE Requires Synchronization And Standards Support In LTE deployments, network synchronization is key and solutions need to meet the rigorous timing and delivery requirements that ensure network quality and availability. Of course, synchronization technology and standards are necessary to support LTE deployments, and various synchronization options are available. “Synchronization” refers to the technique applied to […]

One of the threats that face any cellular technology is Bidding Down or Service Degradation. What is Bidding Down? Hackers can use IMSI-impersonating devices to execute DoS attacks, but that’s not all these devices can do. They can also use their status as trusted network nodes to carry out “man in the middle” attacks, where they […]

To understand how 5G achieves the higher data rates, we need to dig into Shannon’s Law to see how engineers have tackled each of the limiting factors from previous generations. Shannon’s Law This is a simplified version of Shannon’s Law: 5G improves data rates by attacking the first two components of Shannon’s Law directly: More […]

Open RAN Open RAN is the industry’s generic term for an open radio access network architecture. An Open RAN has open interoperable interfaces, RAN virtualization, and support for big data and AI-enabled RAN. Providers deploying an Open RAN can choose between a 3GPP or O-RAN architecture. vRAN It refers to the virtualization of RAN functions, […]

Yes, In general, there are some points that are related to the frequency band but the primary factor is BW as below: Bandwidth: You can reserve more bandwidth for the frequency band as the band there is not congested like the low band. For example, 2G,3G,4G, WiFi, and many wireless technologies are working in a […]

All 5G iPhone 12 models support Dual SIM mode, which refers to the ability to switch between a SIM card and an eSIM operating on independent numbers and/or carriers. However, an image of a training document from Apple’s Sales Web resources called “What you need to know about 5G on iPhone” and posted to Reddit suggests the ‌iPhone 12‌ will […]

Fixed wireless access is defined as a connection that provides broadband access through mobile network-enabled customer premises equipment (CPE). This includes various form factors of CPEs, such as indoor (desktop and window) and outdoor (rooftop and wall-mounted). It does not include portable battery-based Wi-Fi routers or dongles. Fixed wireless access (FWA) connections are forecast to […]

System Information in 5G NSA vs. SA Deployment In NR non-standalone (NSA) deployment, the UE does not necessarily need to receive NR system information blocks (such as SIB1) or any NR paging messages because all the information can be sent to the UE through LTE control plane signaling in connected mode when the 5G Secondary […]

In 4G network systems, it was near impossible to install new services in the network for a UE.  In the 5G network, the slice selection policy can be configured dynamically through URSP, while slice selection policy is pre-defined and cannot be changed dynamically in the 4G network. Through the URSP feature, 5G network operators can […]
