A gNB (gNodeB) in 5G is the base station component that connects user equipment (UE) to the 5G network. It handles radio communication and controls the radio access network (RAN) functions, similar to the eNodeB in LTE networks but designed for the higher capabilities and features of 5G. What is gNB in 5G? gNB (gNodeB) … Read more
The range of a 5G mobile signal varies depending on the frequency band used. Low-band 5G, also known as Sub-6 GHz, can cover several kilometers and offers better penetration through buildings and obstacles. Mid-band 5G typically covers hundreds of meters to a few kilometers, balancing coverage and speed. High-band 5G, or millimeter waves, generally provides … Read more
A RAN (Radio Access Network) is a network component that connects end-user devices to the core network. It encompasses all the hardware and software needed to provide wireless connectivity, including base stations, antennas, and associated network infrastructure. RANs handle the radio communications between user devices and the network, managing tasks such as signal processing, radio … Read more
5G is generally considered better than LTE due to its higher data transfer speeds, lower latency, and increased capacity. It supports more simultaneous connections, enabling advanced applications such as augmented reality, smart cities, and IoT. 5G networks offer significant improvements in performance and efficiency over LTE. Why LTE and not 5G? LTE might be preferred … Read more
Yes, 5G is significantly better than 1G. 1G (First Generation) was an early analog technology focused solely on voice communication, with limited range and capacity. In contrast, 5G (Fifth Generation) is a modern digital technology that offers extremely high data speeds, low latency, and the ability to connect a vast number of devices simultaneously. 5G … Read more
BLER in 5G stands for Block Error Rate. It is a critical metric used to measure the quality and reliability of a communication link in 5G networks. Specifically, BLER represents the percentage of data blocks or packets that are received with errors and cannot be corrected, resulting in the need for retransmission. In 5G networks, … Read more
The NAS (Non-Access Stratum) message in 5G refers to signaling messages exchanged between the User Equipment (UE) and the Core Network, specifically within the 5G system architecture. NAS messages handle functions such as session management, mobility management, and authentication, and are crucial for establishing and maintaining communication between the UE and the network. Which is … Read more
The difference between 5G and 5G DSS (Dynamic Spectrum Sharing) lies in how spectrum is utilized. 5G DSS allows operators to share existing LTE spectrum with 5G, enabling a more gradual transition to 5G by using the same frequencies for both 4G and 5G services. Traditional 5G, on the other hand, relies on dedicated spectrum … Read more
5G is considered necessary for several reasons, including its ability to provide higher data speeds, lower latency, and support for a larger number of connected devices. It enables advanced applications like autonomous vehicles, smart cities, and enhanced augmented reality experiences, which require the capabilities that 5G offers. Does it make sense to switch from 4G … Read more
E-UTRAN (Evolved Universal Terrestrial Radio Access Network) in 5G refers to the radio access network that provides wireless connectivity between user devices and the core network. It encompasses the base stations, known as eNodeBs in LTE and gNodeBs in 5G, which manage radio resources and facilitate communication between devices and the network. What is E-UTRA … Read more
