Some very interesting choices in the latest National Telecommunications and Information Administration (NTIA) funding round from its Wireless Innovation Fund. The focus is on #OpenRAN RUs (radio units) and there’s some very forward-looking ideas for #5G and also #6G. Airspan Networks got 4x the cash of any of the other eight applicant, which is interesting given its financial challenges in recent years, and recent restructuring (it was taken private a few months ago). It’s a potential key player for 3rd party 5G RUs in specific domains (eg indoor, rail, military, specific capabilities) where MNOs get their CU/DU from a single major vendors, but want still supplier diversity in the RAN. DeepSig, Inc. is working on spectrum-sensing built into the RAN, a concept which I wrote about recently (see link in comments). That’s potentially really important in various #spectrumsharing scenarios, as well as for interference detection and mitigation. There seem to be three projects focused on “upper midband” radio components and also MIMO for future 6G in 7-24GHz - it seems that Otava, Inc , NYU WIRELESS and Analog Devices are all looking at that. [NB - I’ll be looking at any changes to US spectrum policy & new bands / auctions under the new administration, in coming months]. SecureG is developing a way to identify radio hardware components uniquely - something that gets more important for supply chain verification & security in a multi-vendor network. The Episys Science award references 3GPP Sidelink (which is for device-to-device connectivity) in the context of OpenRAN. I’m not sure exactly what that refers to, but I suspect it’s for defence-sector 5G / 6G networks, where connections may be important in places & situations without traditional MNO infrastructure. Rampart Communications has its own physical layer technology for wireless & looks to be pushing it as a future 6G protocol, talking about its spectral efficiency. It also has a defence background. Skylark Wireless is working on combining SDR and MIMO within an OpenRAN RU. There’s also notable line in the press release around MNO partnerships as well “Applicants were required to partner with a mobile network operator to help produce products that will be commercially viable”. It’s unclear if that just means mainstream commercial MNOs, or if it can also include private networks, integrators & specialist network operators. Overall, this further underscores US interest in OpenRAN and a domestic / sovereign supply chain - and also the growing importance of cellular networks in sectors like the military. https://lnkd.in/ea5xsBbY

Several internet service providers (ISPs) in Indonesia have begun modernizing their infrastructure by replacing Optical Line Terminal (OLT) and Optical Network Terminal (ONT) equipment from Chinese vendors such as Huawei, and ZTE with European alternatives, particularly Nokia. This shift is driven by the need for higher capacity, stronger trust, better interoperability, and alignment with global regulatory trends. Data from Dell’Oro Group (2024) shows that Nokia, along with Huawei, ZTE, and FiberHome, remains among the top four PON equipment suppliers. However, Nokia’s market share in XGS-PON has been growing more rapidly due to its focus on premium markets and large ISPs in Europe and Asia-Pacific, signaling that this modernization trend toward Nokia technology is also taking root in Indonesia. From a technology standpoint, Nokia’s solutions support XGS-PON (10 Gigabit Symmetrical Passive Optical Network) and even 25G PON, making them far more prepared to meet future bandwidth demands such as 8K IPTV, cloud gaming, smart city infrastructure, and enterprise connectivity. In contrast, many Huawei and ZTE networks in Indonesia are still based on GPON (2.5 Gbps downstream / 1.25 Gbps upstream), which is increasingly limited as video streaming and cloud service penetration continues to rise. An Open Signal (2023) report confirmed that broadband data consumption in Indonesia has grown significantly, with average usage exceeding 400 GB per month per fixed broadband user, underscoring the urgency for migration to next-generation PON. Beyond performance, network security is another consideration. While Indonesia has not issued official bans on Chinese equipment, global trends reflect mounting concerns over cybersecurity risks. The European Union Agency for Cybersecurity (ENISA, 2023) noted that operators in Europe are increasingly reducing reliance on Chinese vendors, especially Huawei, and moving toward non-Chinese suppliers such as Nokia. Indonesian ISPs are beginning to take similar steps to maintain supply chain flexibility and strengthen their brand image in enterprise, state-owned, and government segments that demand high reliability. Economically, although Nokia equipment is “more expensive,” its high reliability makes the Total Cost of Ownership (TCO) more efficient. A Heavy Reading (2022) study highlighted that Nokia’s premium ONTs have an average lifespan of 7–10 years, compared to 4–6 years for mid-range devices, thereby lowering lifecycle costs. This phenomenon is expected to reshape Indonesia’s broadband market landscape. Chinese vendors will likely maintain strong market share in the low-cost ISP segment and tier-2 regions that are highly price-sensitive. However, for backbone modernization and FTTH deployments in major cities, Nokia is increasingly viewed as the strategic choice.

From 4G to 5G: How Base Station Architecture Has Evolved The mobile network we rely on today looks very different from just a few years ago—and much of that change starts with the base station, the foundation of wireless connectivity. Let’s break down the key evolution from 4G to 5G in simple, practical terms: 4G Era: Monolithic & Integrated In 4G/LTE, base stations were mostly integrated, closed, and hardware-heavy. • Traditional eNodeB with tightly coupled baseband and radio units • Limited flexibility for dense urban or high-capacity scenarios • Deployments focused on wide coverage and mobile broadband • Vendor-locked architectures, making upgrades and expansion costly 5G Era: Distributed, Open & Software-Defined 5G brought a fundamental architectural shift to support higher speed, lower latency, and massive connections. • CU/DU separation: Centralized and distributed units for better scalability • Virtualized & cloud-native RAN: Moving functions from dedicated hardware to software • Open RAN / O-RAN: Open interfaces, multi-vendor interoperability, and reduced lock-in • Massive MIMO, beamforming, and higher spectrum efficiency built into the design • Support for eMBB, URLLC, and mMTC—three pillars of 5G use cases Why This Evolution Matters for Global Operators & Partners • Lower long-term CAPEX/OPEX through flexibility and sharing • Faster deployment and easier network optimization • Better support for IoT, industrial automation, and smart cities • Future-proof architecture that can evolve toward 5G-Advanced and 6G The base station is no longer just a radio device—it’s a smart, scalable, software-driven node powering the next generation of global connectivity. #Telecom #5G #4G #BaseStation #RAN #NetworkEvolution #TelecomInfrastructure #Wireless #GlobalTelc

Evolution of Telecom Sites from 2G to 5G How did telecom sites evolve from 2G to 5G? Why did equipment separation change with each generation? In the early days, sites were simple… Now, components are intelligently distributed for better performance and efficiency. 2G – BTS (Base Transceiver Station) In 2G, almost everything was in one place: BTS Responsible for transmitting and receiving signals Signal processing Radio control 👉 It was essentially one box doing everything. Features: Simple Easy to install Drawbacks: High power consumption Cable losses Low flexibility 3G – NodeB + Beginning of Separation The idea of separating components started to emerge. NodeB (an advanced version of BTS) With evolution, we began to see separation into: BBU (Baseband Unit) Signal processing Control RRU (Remote Radio Unit) Transmit and receive signals Placed close to the antenna Features: Reduced signal loss Higher efficiency Flexible deployment 4G – eNodeB (BBU + RRU Standardization) Component separation became essential: BBU Processing Scheduling Control RRU RF transmission Directly connected to the antenna Features: Better performance Lower latency Possibility of centralization 👉 This led to concepts like: BBU Hotel / Centralized architecture 5G – gNodeB + Virtualization A major transformation happened here. The architecture is further divided into: RU (Radio Unit) Transmission and reception DU (Distributed Unit) Part of processing near the site CU (Centralized Unit) Centralized processing Features: Very high flexibility Supports cloud and virtualization Greater resource efficiency 👉 The network is now closer to software… Not just hardware anymore. Why Did This Evolution Happen? Reduce signal loss Improve performance Lower costs Support higher data speeds Handle massive numbers of users Summary 2G: Everything in one box 3G: Separation begins 4G: Clear split (BBU + RRU) 5G: Intelligent distribution (RU + DU + CU) Real Evolution It’s not just about speed… It’s about the architecture itself.

These are key focus areas for the 5G Advanced Release 18, aiming to build upon the existing 5G specifications and introduce new features and enhancements to meet the evolving needs of various industries and use cases. To fully realize the benefits and new features introduced in 5G Advanced Release 18, a complete end-to-end 5G standalone (SA) system is required. The 5G SA architecture consists of a new 5G Core (5GC) network and 5G New Radio (NR) in the Radio Access Network (RAN). The 5G SA architecture is designed to provide a more efficient, flexible, and scalable network compared to the earlier Non-Standalone (NSA) architecture, which relied on the existing 4G LTE core network. The 5G SA architecture enables: 1. Native network slicing support allows operators to create multiple virtual networks with different performance characteristics on a single physical infrastructure. 2. Service-Based Architecture (SBA) in the 5G Core, enabling a more modular and flexible network design with improved scalability and easier integration of new services. 3. Edge computing capabilities allow for deploying processing resources closer to end-users, reducing latency, and enabling new use cases. 4. Enhanced security features, such as stronger encryption and authentication mechanisms. 5. Improved support for massive IoT deployments and mission-critical applications with stringent latency and reliability requirements. To take full advantage of the features and enhancements introduced in 5G Advanced Release 18, mobile network operators must deploy a complete 5G SA system, including the 5G Core and 5G NR in the RAN. This will require significant investments in network infrastructure.
