In 5G, the PBCH (Physical Broadcast Channel) is not a demodulation reference signal but rather serves to broadcast critical system information to all devices. It uses QPSK modulation, is transmitted in each radio frame, aids in device synchronization, and helps devices retrieve essential network configuration details for connection establishment and maintenance. Is PBCH a demodulation … Read more
A 5G resource block typically comprises 12 subcarriers in the frequency domain and occupies one time slot, which is 0.5 milliseconds long in the time domain. This allocation facilitates efficient data transmission and resource management in 5G networks. How many subcarriers are in a 5G resource block? In 5G, a resource block is the smallest … Read more
How far away should you be from a 5G tower? The distance you should be from a 5G tower varies based on the frequency band. For low-band 5G, you can be several miles away and still receive a signal, while mid-band 5G might require you to be within a few miles. High-band 5G, known as … Read more
To improve your 5G coverage and capacity, consider deploying more cell towers and small cells, utilizing higher frequencies like millimeter wave (mmWave), implementing MIMO technology, optimizing network resources through network slicing, ensuring robust fiber backhaul connections, using carrier aggregation, and employing technologies like beamforming and DAS where needed. Regular network optimization, spectrum management, and cooperation … Read more
In 5G networks, there are three main types of bearers: default bearers, dedicated bearers, and emergency bearers. Default bearers are established when a device connects to the network and handle initial setup and signaling. Dedicated bearers are created on-demand for specific applications, allowing for differentiated Quality of Service (QoS) based on the application’s requirements. Emergency … Read more
Active antenna systems (AAS) in 5G are complex arrays with individual RF components, enabling dynamic beamforming, massive MIMO, and high performance, making them suitable for high-capacity scenarios but costly. In contrast, passive antenna systems are simpler and lack individual RF components, offering fixed radiation patterns and lower costs, making them suitable for straightforward coverage needs … Read more
What is the transmission time interval tti of 5G supports? Transmission Time Interval (TTI) defines the duration of a radio frame for data transmission and reception. 5G supports a range of TTI values, from as short as 1 millisecond for ultra-low-latency applications like remote surgery to longer intervals like 10 milliseconds or more for less … Read more
