From Santa Clara to the Alps: Event-Worthy Wireless Networks

As fans flood California’s Bay Area and Levi’s Stadium this week for Super Bowl LX, their eyes will be on the field, but the real marvel is happening behind the scenes: a meticulously orchestrated, high-capacity wireless network engineered to support tens of thousands of simultaneous devices, streams and transactions. For wireless professionals, the Super Bowl is more than a sporting spectacle — it’s a massive stress test, demonstrating how cellular networks, distributed antenna systems, small cells, Wi‑Fi, spectrum layering and cybersecurity converge to create a seamless digital experience. From stadium concourses to city streets and transit hubs, this month’s sporting events highlight just how crucial high-performance wireless networks have become.

Levi’s Stadium has long been a leader in venue connectivity, but Super Bowl LX demanded a full-scale upgrade. Costa Kladianos, the 49ers’ EVP of Technology, describes it as a complete rebuild. While the previous system had served the stadium for a decade, mobile connectivity continues to advance, and reaching previously unreachable zones required a modernized approach. Partnering with JMA Wireless, Levi’s installed a digital DAS capable of 5G, multi-band LTE, and future spectrum layers, delivering what Kladianos calls “70,000 VIP experiences” for every fan walking through the doors. Redundant fiber and power paths ensure high availability, while energy-efficient designs reduce the stadium’s carbon footprint. The result is a long-term foundation built to handle extreme device density, high-speed uploads, and ultra-reliable connectivity for years to come.

Carrier networks play a critical role in turning this foundation into an experience fans barely notice. AT&T refreshed the DAS inside Levi’s Stadium and expanded macro and small cell sites around stadium-adjacent fan zones. Verizon, taking a “championship roster” approach, layered C-Band and mmWave deployments for high throughput and capacity. T-Mobile has positioned network engineers inside local emergency operations centers and the Levi’s Stadium command center, augmenting long-term 5G and Ultra Capacity infrastructure with mobile cell sites such as SatCOWs and SatCOLTs and drone-assisted situational awareness to provide rapid capacity and coverage augmentation where needed. It also is leveraging AI-driven Self-Organizing Network (SON) technology to monitor demand and dynamically adjust coverage, capacity and performance in real time across the Bay Area to support both everyday usage and peak conditions. Together, these carriers deployed nearly 200 projects spanning DAS, small cells, and backhaul, with on-site RF engineers and real-time command center monitoring fine-tuning the network for peak efficiency. Small cells targeted high-traffic ingress and egress points, while private slices ensured operational communications remained uninterrupted. The combined system sustains tens of thousands of simultaneous connections with minimal latency, even during tailgate surges.

Connectivity, however, is only half the story. With massive amounts of mobile traffic comes the need for cybersecurity. Levi’s Stadium has installed a dedicated cyber command center to monitor and protect critical operations, from ticketing systems and broadcast feeds to fan apps and payment platforms. It’s not just about speed, Kladianos notes. It’s about reliability, security and resilience. Fans can upload videos, stream replays, and navigate the stadium without interruptions, confident that the underlying network infrastructure is performing flawlessly and securely.

The Super Bowl’s connectivity story extends beyond the stadium. Boldyn Networks partnered with BART to deploy free Wi‑Fi 6E at five key stations, including SFO Airport, Powell Street, Embarcadero, Civic Center, and West Oakland. Using 6 GHz channels and a fiber backbone along the transit right-of-way, the system delivers high-capacity, low-congestion coverage for travelers and tailgaters alike. This infrastructure isn’t just for the event; it lays the foundation for expanded transit connectivity, future small cell backhaul, and lasting benefits for Bay Area commuters and residents.

This month’s Super Bowl is not alone in setting connectivity standards. The 2026 Winter Olympics in Milan and Cortina d’Ampezzo, kicking off this weekend, are also serving as a proving ground for large-scale telecommunications infrastructure. In Italy, the official telecommunications partner TIM has deployed ultra‑fast fiber and 5G across airports, stations and venues, wiring every competition site with advanced data and voice systems and provisioning more than 10,000 devices and routers to ensure high-performance coverage for athletes, visitors and media. Juniper Networks Italy is providing AI‑native networking platforms to optimize real-time data flows and secure the Olympic network, ensuring resilient, measurable and secure connectivity across all venues. Even regional operators like Mynet are building ultra-fast fiber into mountain venues such as Livigno, supporting live streaming and broadcast traffic in challenging terrains. These coordinated efforts highlight how major global events catalyze lasting infrastructure improvements that benefit both visitors and local communities.

Last February, WIA President and CEO Patrick Halley observed how the investment in infrastructure extends far beyond a single event. Stadium upgrades ripple outward to airports, hotels and urban districts, while transit Wi-Fi and fiber deployments establish long-term regional digital assets. Just as the Winter Olympics invested in multi-layered connectivity for athletes, media, and spectators, Super Bowl LX is driving investments in DAS, small cells, Wi-Fi, spectrum and cybersecurity — a reminder that at modern sporting spectacles, wireless networks are the underlying infrastructure that make the experience possible.
