Open Radio Access Network: Is a concept that revolves around the interoperability and standardization of RAN components, encompassing a uniform connectivity standard for white-box hardware as well as open-source software elements provided by various suppliers. The Open RAN design combines a customizable base station software stack with readily available hardware, enabling baseband and radio unit elements from various vendors to work harmoniously. The Open RAN architecture defined by the O-RAN Alliance and supported by 3GPP can be virtualized and containerized by breaking down traditional remote radio head RRH and baseband units BBUs into open radio units O-RUs, open distributed units O-DUs, and open centralized units O-CUs, all while using open and interoperable components. Open RAN sets efficient 5G RAN goals by focusing on efficiency, intelligence, and versatility. Implementing Open RAN at the edge of the network facilitates 5G functionalities like self-driving vehicles, which depend on fast response times and strong dependability, all the while efficiently catering to various network slicing scenarios. Open RAN also allows for safe and effective wireless firmware updates. What is the difference between RAN and O-RAN? please answer this question in the comments.

📡 #LoRaWAN  or #TSUNB (#Mioty / #OMS5)? Since I was personally trained multiple times on #LoRa by #Semtech, accompanied the first major LoRa project in #Germany, wrote the LPWAN Cookbook and studies on LPWAN, and regularly consult companies on LPWAN, I possess more details than others. LoRaWAN must go for technical reasons. Bye bye LoRaWAN, welcome #Mioty, #OMS5, and #TSUNB. 🏠 The First LoRa Mass Production Project in Germany: The first mass production project using LoRa in Germany was the Smart Home Set with #RWE. The development was carried out by Cameronet in Remscheid. Harald Naumann, FAE at Future Electronics, accompanied the project. Electricity meters were read optically, digitised, and sent via LoRa (not LoRaWAN). The PDFs of the LoRa IC were so poor that we simply had to experiment with the parameters. 📷 Outdated Technology in the Smart Home Set: The display of the electricity meter was redirected using two mirrors, photographed with a camera, and then converted into a digital value by an embedded #Linux PC. Today, this method is outdated and much too expensive. An #ESP32 now does the same with an open-source library, at a significantly lower cost and with less energy consumption. 💡 RWE Ahead of Its Time: RWE was far ahead of its time with this idea. Nowadays, it is mandatory to provide consumers with their energy consumption monthly by German law. Since there is only one electricity meter per household, it’s relatively simple there. However, in Germany, many radiators use devices called heat cost allocators for reading. In the past, this data was read manually, but today, it’s done via Wireless M-Bus. 📶 OMS and Mioty - A Better Solution: The OMS Group specifies WM Bus. In OMS5, TS-UNB is integrated. Miotyis the brand name for TS-UNB. The latest version of TS-UNB was adapted to the OMS Group’s requirements. 🔋 Efficiency of OMS5 and Mioty: The old TS-UNB transmitted at 300 bit/s, while the new version use 2400 bit/s. OMS5 and Mioty require 4.5 times less energy than LoRaWAN at the same range. A sensor with a SoC based on TS-UNB does not need an expensive LoRa PHY and requires a smaller battery. The battery is the most costly component in a heat cost allocator or water meter. 🌍 LoRaWAN vs #OMS5 in EU: The largest LoRaWAN operator globally is #Zenner, with only 7 million sensors after 8 years of acquisition. Zenner primarily operates in sub-metering and not LPWAN. Just one OMS member produces 7 million WM Bus sensors annually. Therefore, the #OMS Group is much larger in production in EU than the LoRaWAN Alliance members. 💪 Mioty, OMS5, TS-UNB vs LoRaWAN: 4.5 times less energy consumption, double the range, no vendor lock-in, very cheap SoCs, 10 times less bandwidth, 500 times the data throughput .... Bye bye LoRaWAN - welcome Mioty, OMS5, TS-UNB.

📖 Fairy tales in #IoT. How many storytellers are there in #wireless IoT? The last storyteller I personally met claimed to save 90% of energy with #NBIoT when using its internal SIM card on the radio module. Forty more listeners were in the room. No one contradicted him? No one—well, I did it with one sentence and didn't expose him with facts. 🔍 The facts about energy consumption in #LPWAN have already been determined in the study "Energy Consumption in LPWAN with #NBIoT, #LoRaWAN, and #Sigfox." Details and link to the study in the comment. 📊 The energy consumption of a SIM card in sleep mode is in the range of uA for NB-IoT. The internal SIM card in the module also requires uA. You save a few uA. At the same time, you get a vendor lock and only a few NB-IoT or NB-IoT / #LTEM modules to choose from. 📡 The named module is based on an old chipset. Newer chipsets like the Sony Altair ALT1350 require less energy. In total, an #AltairSoC ALT1350 with a #multiIMSI SIM card from #Crout requires less sleep current than the internal SIM card in the old chipset with a vendor lock. 💡 Sending once a day with NB-IoT requires much more energy than the sleep or idle current within 24 hours. 💬 Internet SIM card with single IMSI versus External SIM card from Crout with Multi IMSI. Who wins in the competition? Who would you bet on? 🎯 Crout sends Harald Naumann with experience in wireless communication and Achim Kraus a software expert into the competition. Achim has optimized the code over 24 months and controls the Multi IMSI via the host. The MCU automatically switches between 6 network operators for NB-IoT and LTE-M in Germany and many other network operators in other countries. We have better network coverage than the opponent with vendor lock. With equal coverage, we select the better one through our algorithm and save energy again. 🏆 Who wins the competition in energy consumption with NB-IoT and LTE-M in the long-term test? Achim and Harald with extensive experience and open source or the other with old chipset, internal SIM card, vendor lock, and single IMSI? 📧 Anyone who wants to try out the Crout Multi IMSI SIM card with open-source code for client and server is welcome to contact us. The SIM card is free for testing. Our server can host multiple IoT companies simultaneously. You can use our server at the beginning. Furthermore, non-binding pre-registrations welcome for the webinar with 16 lessons. 2 x 45 minutes per day spread over 8 days and 2 weeks.

How did early adopters *actually* integrate #GenAI with a lasting impact? My experience: a “soft launch” is possible by deploying AI projects first on internal use cases and scaling to client-facing applications once you gain confidence with your initial project. We recently helped Semilab Zrt, a leading European semiconductor manufacturer, start their GenAI journey by hooking up a language model to their whole company knowledge base. This made their unstructured data sources available in a chatbot-like format, and their workforce could query anything from corporate policies to known best practices. The results are quantifiable: An instant 10% efficiency boost by enabling a better flow of information! If you want to see technical details, check out our recent case study on the Hiflylabs website: https://lnkd.in/d6sFmk6V And don’t forget to ask yourself: how are we utilizing AI to actually make life easier?

I am convinced that fairly soon you'll only be able to make contact with valuable people through Tela (or some similar service). They're busy, they're working, they don't want to be bothered unless it actually matters. So: A message from a friend on a normal messaging app is fine. A warm intro via a colleague is fine. But a random stranger is _usually_ an unproductive loss of time, because you'll have to spend effort to figure out if the person is genuine, and not a scammer, and not crazy, etc. (and AI is going to make this infinitely worse.) So: Check out Tela. It's the future. 💎 On Tela, every message pays you. Use Tela to reduce your inbox overload. 👉 You can sign up here: https://lnkd.in/ehFQsjsH

🌍 Pimp Up Your #Pump: #Wireless #IoT for Global Pumps. The reference design with sensors and app on #Bluetooth is ready to ship. Our extension PCB, supporting any kind of #LPWAN (#5G NTN, #NBIoT, #LTEM, #Mioty, #Sigfox, #LoRaWAN), is ready to ship. The necessary 0 Euro #antenna concept is field-approved. 📈 Market Overview According to a 2020 report by the International Water Association (#IWA), there are ~10 million water pumps and 4 million wastewater pumps worldwide. In Europe, the number of pumps is significantly lower due to higher infrastructure density, although exact figures are unavailable. 💰 Growth Projections The global pump market is projected to reach $50.15 billion by 2024, growing to $61.42 billion by 2030. This growth is driven by several factors: - Increasing Water Demand: Population growth, urbanization, and industrialization drive the global demand for water, leading to a higher need for pumps in water supply, irrigation, and wastewater disposal. - Infrastructure Investments: Many countries are investing in water and wastewater infrastructure to improve quality and access, boosting demand for new pumps. - Industrialization: Emerging markets see rising industrialization, increasing pump demand in sectors such as chemicals, petrochemicals, and food processing. 🏭 Key Market Segments; - Water and Wastewater Pumps: The largest segment of the global pump market, expected to continue growing in the coming years. - Industrial Pumps: Used in various industries, including chemicals, petrochemicals, and food processing. - Oil Pumps: Employed in the extraction of crude oil and natural gas. - Building Services Pumps: Used in heating, ventilation, and plumbing systems within buildings. Which LPWAN technology is the right one? For pumps in buildings, I prefer NeoMesh from NeoCortec and therefore no LPWAN at all. For pumps in the oil field I prefer 5G NTN to reach areas in the desert or in the sea. For water and wastewater pumps in cities, I prefer NB-IoT and LTE-M or city-wide LPWAN with Mioty. If NB-IoT is not available, I use Sigfox. My Mioty client for 30 cents can also do Sigfox. Which technology do you prefer? 📩 Stay Connected: Subscribe to my #IoT #M2M Times (newsletter) on LinkedIn.

This paper proposes a novel channel training-based protocol, which is capable of striking a #flexible #trade-#off between performance, pilot overhead and complexity. More specifically, first of all , the auhtors conceive a holistic protocol that intrinsically amalgamates the existing channel estimation and passive beamforming optimization for creating a new unified scheme. Secondly , they propose a new #channel #training #framework. In contrast to the conventional channel estimation arrangements, their new framework divides the #training #phase into #several #periods and has the compelling benefit of directly estimating the superimposed #end-#to-#end channel instead of separately estimating the direct BS-user and reflected RIS links, which would not lend itself to near-instantaneous reconfiguration in the face of #high-#Doppler #mobility. As a result, the RIS reflecting coefficients are optimized by comparing the objective function values over multiple training periods, which leads to optimal performance, despite its reduced complexity as well as reduced signaling and pilot overhead. Thirdly , they analyze the theoretical performance of both the #channel #estimation-#based #protocol and the #channel #training-#based #protocol in the presence of channel estimation errors. Finally , their theoretical analysis is confirmed by numerical simulations. ----Jiancheng An, @Chao Xu, @Li Wang, @Yusha Liu, @Lu Gan, Lajos Hanzo More details can be found at this link: https://lnkd.in/eCjv3gFm

Deploying #reconfigurable #intelligent #surfaces (#RISs) near source and destination is of practical interest for improving the link quality of #vehicle-#to-#vehicle (#V2V) wireless systems. However, the accurate channel modeling and RIS tile deployment constitute a pair of challenges to evaluate the system performance, such as error performance, capacity, etc. In this article, the authors investigate the double-RIS channel characteristics and propose a geometry-based triple-cylinder model, where the RIS subsurface/tile is enabled to assist V2V systems and other elements are turned off. To determine tile locations on RIS surface, they formulate an optimization problem by maximizing the end-to-end channel gain and solve it using #gradient #ascent (#GA) method. Following this, channel correlation function, channel capacity, and outage probability are derived according to the proposed model. Five typical mobile scenarios are discussed to validate the convergence of proposed GA algorithm, where the results show that channel gain can converge to its maximum with optimized tile locations. In addition, channel correlation under different parameters and conditions are explored. ---- Guiqi Sun, Ruisi He, Jiancheng An, Bo Ai, Yaxin Song, Yong Niu, Gongpu Wang, Chau Yuen More details can be found at this link: https://lnkd.in/e-N3zzpq
