5G Network Implementation

Super Bowl LIX wasn’t just a showcase of top-tier football—it was also a test of how well the networks could handle one of the most demanding connectivity environments in sports. As the Philadelphia Eagles celebrated their victory, New Orleans’ telecommunications infrastructure quietly played a crucial role in keeping fans, media, and businesses connected across the Caesars Superdome, tailgate zones, hotels, the airport, and the French Quarter. While much of the spotlight is on game day, T-Mobile, Verizon, and AT&T took a long-term approach, ensuring that their investments would benefit the city far beyond the Super Bowl. T-Mobile took a broad approach, focusing on both in-stadium upgrades and wider city improvements to keep fans connected wherever they were. -Upgraded its Distributed Antenna System (DAS) inside the Superdome, enabling peak speeds of 1.2 Gbps for fans in the stadium. -Enhanced macro cell sites in high-traffic areas like Champions Square, boosting speeds up to 920 Mbps. -Expanded its 5G network across New Orleans, adding permanent improvements to the French Quarter, key hotels (Hyatt Regency, JW Marriott, Roosevelt), the airport, and the Smoothie King Arena. Verizon focused on delivering high-speed connectivity in dense environments, making key enhancements to its 5G Ultra Wideband network: -Installed 509 Ultra Wideband radios and 155 C-Band radios inside the Superdome to provide consistent coverage across seating areas, suites, and concourses. -Mounted 42 MatSing Ball Antennas on the stadium’s catwalks, improving capacity in crowded sections. -Laid down 560+ miles of new fiber across New Orleans, permanently improving connectivity in areas like Bourbon Street, the airport, and other key venues. AT&T: A Critical Role as the Neutral Host Key Investments: -A significant DAS upgrade featuring 91 zones of 5G+ C-Band, 3.45 GHz, and mmWave, improving capacity across the stadium. -Outdoor antenna system enhancements, ensuring strong connectivity in tailgate areas, parking garages, and fan zones. -City-wide 5G+ expansions, with 69 small cell upgrades and C-Band overlays, particularly in high-density areas like the New Orleans Convention Center. The infrastructure investments made for Super Bowl LIX are a blueprint for how connectivity should be approached at large-scale events. Planning ahead is crucial. The carriers spent years preparing for this one-day event. At LA28, we are planning for a global audience across multiple venues for weeks at a time. Adaptability is essential. The ability to optimize networks in real time using cloud-based vRAN, C-Band, and mmWave proved valuable in managing massive data surges. Lasting impact matters. The networks deployed for the Super Bowl aren’t just for the game—they now serve as part of New Orleans’ long-term telecom infrastructure. The next step? Taking these learnings and applying them to the world’s largest sporting event. #SuperBowlLIX #topvoices

Frequency Escalation in UAV Systems – Transmissions in the 7.5–12 GHz Band Recent observations indicate a clear upward shift in the radio spectrum used by unmanned aerial systems (UAS). Traditional ranges for command and video links — 300 MHz to 7.2 GHz — are now heavily saturated. Consequently, more UAVs are operating within the 7.5–12 GHz band, entering the centimeter-wave (SHF) domain rarely used by small and medium-class drones. Field reports confirm analog video transmitters above 8 GHz, marking a significant departure from the standard 2.4 GHz and 5.8 GHz bands. Operating higher enables avoidance of interference and greater data throughput, especially for HD and 4K video with minimal latency. This, however, demands high RF precision and antenna stability, as even minor detuning degrades link performance. Frequencies above 7 GHz mean shorter wavelengths, faster attenuation, limited obstacle penetration, and strict line-of-sight requirements. Maintaining stable connections requires high-gain directional antennas, increased transmitter power, or airborne relay UAVs to sustain long-range links despite terrain masking. Operation in the 8–12 GHz range allows wider bandwidth and lower latency but requires advanced RF filtering, thermal stabilization, and high-linearity amplification (LNA/PA). This raises system complexity while reducing detectability. Most current detection and counter-UAS (C-UAS) systems cover up to ~7 GHz. Thus, new UAVs may operate beyond detection. Analog modulation at these frequencies generates non-standard spectral signatures not recognized by common RF classification algorithms. To adapt, infrastructures must expand spectrum monitoring to at least 12 GHz, update RF signature libraries, upgrade analyzer firmware, and test jamming effectiveness in the 8–12 GHz range. The ongoing upward shift in UAV frequencies marks a new phase in unmanned architecture, emphasizing adaptability, dynamic channel allocation, and resilience in contested electromagnetic environments. The spectrum itself has become a battlefield — one where superiority depends on intelligence, agility, and precise spectrum management.

I love Markus J. Buehler's work, and his latest paper "Agentic Deep Graph Reasoning Yields Self-Organizing Knowledge Networks" does not disappoint, revealing powerful structures to accelerate scientific discovery. Central insights (link to paper in comments): 🤖 Self-organizing knowledge networks help open-ended discovery. Unlike conventional knowledge graph models, the proposed framework iteratively expands and refines its knowledge representation with autonomous reasoning. By integrating a reasoning language model with a dynamically updated graph, the system develops a scale-free network where hubs and bridges naturally emerge, leading to continuous knowledge expansion. 🌍 Bridging nodes drives interdisciplinary knowledge integration. Over hundreds of iterations, the model reveals an increasing number of bridge nodes—concepts that connect distinct domains—mirroring the way human scientific discovery links disparate ideas. These nodes enable cross-disciplinary insights, showing that autonomous reasoning systems can generate novel, high-impact connections. 🔁 Recursive graph expansion mirrors scientific breakthroughs. The study reveals alternating phases of stability and conceptual restructuring, similarly to the advance of human knowledge. Some concepts gradually accumulate influence, while others experience sudden bursts of connectivity, showing breakthrough moments in knowledge formation. This suggests that AI-driven knowledge synthesis can replicate real-world scientific discovery dynamics. 📈 Scale-free and small-world properties enhance knowledge navigation. The resulting knowledge graphs exhibit hallmark properties of efficient information networks: they are scale-free (few highly connected hubs, many weakly connected nodes) and small-world (short paths between most nodes). These make the system navigable, coherent, and easily searchable. 🔄 Agentic graph-based reasoning strengthens scientific hypothesis generation. By using an iterative reasoning process, the system autonomously identifies and refines scientific hypotheses. The study demonstrates how AI can assist in knowledge synthesis for fields like materials science and sustainability, accelerating discovery processes by revealing hidden relationships between research areas. 🛠 Future AI systems could simulate scientific thought processes. The findings suggest that AI models capable of recursively structuring knowledge—rather than merely extracting or predicting information—could revolutionize scientific research. By allowing concepts to evolve over time, these systems may eventually approach human-like intelligence in scientific reasoning, with applications spanning biomedicine, engineering, and more. These are the kind of structures that will help accelerate scientific progress.

5G Spectrum (5G Series - Part 6) The 5G spectrum is one of the most valuable and expensive assets for telecom operators, with investments running into millions of dollars for just a few megahertz of spectrum. Given the high stakes, choosing the right spectrum is critical for any telco's success. As we exhaust the lower frequency bands used in legacy technologies, 5G offers more flexibility with higher frequency ranges. There are two primary frequency ranges in 5G: 1. Frequency Range 1 (FR1): 450 MHz to 7 GHz These are lower frequency bands with smaller bandwidth chunks. For example, up to 45 MHz is available in the 900 MHz range. While mid-band options like the 3.5 GHz (N78 band) provide larger bandwidths. FR1 offers better coverage but comes with limitations on throughput and data rates. 2. Frequency Range 2 (FR2): 24 GHz to 52.6 GHz Known as millimeter wave (mmWave), FR2 offers much larger bandwidth chunks, around 3,000 MHz per category, enabling significantly higher data speeds. However, the trade-off is reduced coverage compared to lower bands, making FR2 ideal for high-capacity but smaller coverage areas. The Trade-Off: Coverage vs. Capacity Lower frequencies (FR1) provide broader coverage but with lower data rates, while higher frequencies (FR2) offer higher capacity and throughput but cover smaller areas. To optimize both, telcos need a balanced mix of low, mid and high-frequency bands to provide strong coverage alongside the capacity to handle high data demands. When planning 5G spectrum, it’s important to consider the different standards, bands, and bandwidth chunks available. Tables showing these details are crucial for effective spectrum planning, helping operators make informed decisions about their network strategy. 👉 To master 5G technology, visit - https://lnkd.in/eSYuK9V7 #telecom #technology #learning #platform #itelcotech

Once a telecom gal, always a telecom gal ... I may live in the world of enterprise AI today… But sometimes, my telecom side sneaks out — loud and proud. That’s exactly what happened when I wrote this piece for Communications Today: 👉 Agents? Telecom knows them as SON Because here’s the truth: before everyone was buzzing about “agents,” telecom had already been there, done that. We called it SON — Self-Organizing Networks. Think about it: ➡️ Didn’t SON already manage neighbor relations better than most humans do? ➡️Didn’t it handle PCI conflicts before you even knew they existed? ➡️Didn’t it optimize handover parameters so users never dropped calls mid-conversation? ➡️Didn’t it balance load across cells while sipping digital coffee in the background? ➡️Didn’t it trim energy consumption before ESG made it trendy? So why are we acting like “agents” are brand new? The buzzword may have changed, but the DNA is the same: automation, autonomy, and trust in machines to do the heavy lifting. SON was the OG agent. It paved the way for what we now hype in AI, cloud, and enterprise automation. Back in 2009. And here’s the fun part: telecom taught me lessons I still use in enterprise every single day — build for resilience, design for scale, and never underestimate the chaos of a traffic spike. Because whether you’re managing a mobile network or an enterprise workflow… Automation isn’t magic. It’s engineering. OK, engineering magic :) Let me know what you think: https://lnkd.in/e_aXqQ8v

SNMP is commonly used for network monitoring... But is model driven telemetry better? SNMP has been the de facto standard for network monitoring for over 34 years. SNMP: → pull-based (only gets device info when queried) → frequent polling can add strain to your network → difficult to provide "real-time" responses But as network deployments grow, and traffic needs increase - SNMP polling has trouble scaling. Model driven telemetry is a newer approach that is becoming the preferred method for monitoring. Model driven telemetry: → reduces bandwidth and CPU overhead → very efficient to send to multiple recipients → data can be sent periodically or on an event trigger → push model (data flows continuously to subscribers) As more devices support telemetry it's becoming more practical to use across your network. Overall, telemetry gives you more data, with better performance. P.S. Have you tried using model driven telemetry? What do you think?
