Network synchronization is the cornerstone of optimal RAN performance and technologies like LTE TDD, Elastic RAN, Advanced RAN Coordination, and NR TDD RAN rely heavily on precise frequency, time, and phase synchronization. However we have observed that recent disruptions in GNSS have raised concerns, stemming from natural phenomena like solar flares to the accessibility of low-cost jamming equipment. We have to make sure we navigate these challenges and ensure the resilience of our mobile network synchronization solutions. Which brings me our latest paper that I have commissioned on this very topic: Role of synchronization in empowering 5G networks. It's packed with valuable insights and actionable recommendations, including setting the right parameters, tracking multiple GNSS services, leveraging multi-band GNSS, and utilizing network-based secondary timing sources like the cesium clock. If you'd like to take the opportunity to delve deeper into the world of synchronization, I'd recommend you to register and download the paper that'll help you navigate the complexities of mobile network synchronization with confidence. #EricssonMEA #Synchronization #5G #Connectivity https://lnkd.in/dWMExi4c

What is bandwidth and each bandwidth how many PRB? ???????? **Bandwidth** in wireless communication refers to the range of frequencies used for transmitting data over a network. In mobile networks like LTE (Long-Term Evolution) and NR (New Radio, used in 5G), bandwidth is divided into smaller resource units called **Physical Resource Blocks (PRBs)**, which are allocated to users for data transmission. The number of PRBs depends on the channel bandwidth and the frequency band being used. Below are typical numbers for LTE: - **1.4 MHz bandwidth**: 6 PRBs - **3 MHz bandwidth**: 15 PRBs - **5 MHz bandwidth**: 25 PRBs - **10 MHz bandwidth**: 50 PRBs - **15 MHz bandwidth**: 75 PRBs - **20 MHz bandwidth**: 100 PRBs These values are based on the fact that one PRB corresponds to 180 kHz of bandwidth. The number of PRBs may vary slightly in different network configurations.
5G coverage (eMBB) 5G coverage is evaluated by calculating Maximum allowed path loss (MAPL) on radio interface using link budget tool. This tool estimates the achieved values of path losses over the planned environment, between the transmitter and receiver in the uplink (UL) and downlink (DL) directions. This initial planning phase helps Telcos to achieve a high-level estimation of the number of base stations needed to service the planned area considering different services, frequency band, channel model, control or data channel, cell reliability, packet error, pathloss model, base station height, antenna technique, clutter type, 5th percentile spectral efficiency and other system parameters. Above mentioned multiple factors can vary from one telco to another and therefore can change the coverage planning and penetration. Here, coverage is evaluated for eMBB for 3.5GHz frequency band as an example to understand the coverage calculation steps on broader level. As, UL coverage is less than DL coverage, network needs to planned on the basis of UL calculation always.

fgOTN to revolutionise communication networking in the power sector
Huawei has launched the first fgOTN-compliant optical transmission product for the power sector and other industrial applications.
Over the past few decades, SDH (Synchronous Digital Hierarchy) technology, which features high reliability and deterministic low latency, has been widely used in private networks in industries such as electric power and transportation and in those of carriers, governments and enterprises. As intelligent services continue to grow, SDH technology has had to confront its bandwidth challenge.
Read the latest feature from Huawei, and insights from Dr. Xiang Liu, a senior expert in international optical communications standards on this topic.

What is a Combiner in Telecom Networks? ???? Add your thoughts regarding this…… A Combiner is a crucial device used in telecom networks to streamline signal transmission. It merges signals from different technologies, like 3G and 4G, and sends them through a single antenna. This not only reduces the number of antennas needed but also optimizes space and network efficiency. Key Benefits of Using a Combiner: Minimizes the number of antennas required on towers. Reduces signal interference for clearer connections. Boosts overall network performance. ???? Combiners play an essential role in simplifying operations while enhancing the quality of network infrastructure. #Telecom #Networking #Innovation #3G #4G #NetworkOptimization #Efficiency #TelecomEngineering

See what ODVA's Steven Fales has to say about ensuring consistent performance and reliability of Industrial Ethernet in Control Engineering Europe's article "Overcoming the challenges of harsh environments" by Suzanne Gill. "The EtherNet/IP Industrial Ethernet network supports wireless communications, including 5G, as a media independent network since it relies on the Common Industrial Protocol (CIP) at the application layer. However, Radio Frequency Interference (RFI) from Wi-Fi, 5G and other wireless communications in plants can be a concern. Ensuring that line of sight is maintained for wireless communications to avoid interference is a best practice. Additionally, having repeaters available for wireless networks can help maintain proper network performance if there is too much Electromagnetic Interference (EMI) and/or RFI in the area.” Read the full article here: https://lnkd.in/ePYdBEaB #ODVA #IndustrialEthernet #EtherNetIP #CIP #Wireless #5G #WiFi #RFI #EMI #HarshEnvironment
