The 5G Reality Check: Stadium Tests Reveal a Capacity Crisis and What It Means for the Future of Connectivity
Forget downloading movies on the tarmac. The real test of a modern cellular network isn’t about peak speeds in a lab; it’s about consistent performance when tens of thousands of people are simultaneously trying to connect. Recent tests at a Chicago Cubs game, mirroring experiences at concerts and amusement parks nationwide, reveal a sobering truth: despite years of 5G rollout, network capacity remains a critical bottleneck, and the promises of seamless connectivity in crowded spaces largely remain unfulfilled.
The Wrigley Field Experiment: A Microcosm of Network Strain
A recent investigation, conducted during a Cubs playoff game, meticulously tracked the performance of Verizon, AT&T, and T-Mobile within and around Wrigley Field. The results, while geographically limited, paint a stark picture. While blazing-fast speeds – exceeding 2,600 Mbps on Verizon – were achievable away from the stadium, performance plummeted dramatically as the crowd swelled. T-Mobile, in particular, struggled, experiencing complete connection failures in some areas. This isn’t simply a Chicago problem; it’s a fundamental challenge of delivering reliable connectivity in high-density environments.
Beyond Speed: The Forgotten Promise of 5G Capacity
When 5G was first touted, the narrative centered on two key benefits: speed and capacity. Speed has seen incremental improvements, but capacity – the ability to handle a large number of connected devices simultaneously – has lagged behind. The Wrigley Field tests underscore this imbalance. The ability to livestream, share photos, and simply make calls during peak times was severely compromised, turning smartphones into expensive cameras for many attendees. This highlights a critical disconnect between the marketing hype and the on-the-ground reality.
The Role of Millimeter Wave (mmWave) and Mid-Band 5G
Much of the initial 5G rollout focused on millimeter wave (mmWave) technology, which offers incredibly high speeds but suffers from limited range and poor penetration of buildings and obstacles. While mmWave can provide a boost in specific, targeted areas, it’s not a scalable solution for widespread capacity. Mid-band 5G, offering a better balance of speed and coverage, is crucial, but its deployment is still ongoing. The Federal Communications Commission (FCC) has been actively working to free up more mid-band spectrum, recognizing its importance for closing the capacity gap.

The Rise of Private 5G Networks: A Potential Solution?
As public networks struggle to keep pace with demand, a growing number of organizations are exploring private 5G networks. These dedicated networks, built and managed by enterprises or municipalities, offer greater control over capacity and performance. Stadiums, factories, and hospitals are prime candidates for private 5G deployments, allowing them to guarantee reliable connectivity for critical applications. However, the cost and complexity of building and maintaining a private network remain significant hurdles.
Network Slicing: A Software-Defined Approach to Capacity
Another promising approach is network slicing, a technology that allows operators to partition their network into virtual “slices,” each tailored to specific applications and users. This enables them to prioritize traffic for critical services, such as emergency communications or live video streaming, even during periods of high congestion. Network slicing is a key component of the 5G standard and is expected to become more widely deployed in the coming years.
The Impact of Network Virtualization and Open RAN
The shift towards network virtualization and Open Radio Access Networks (Open RAN) is also playing a crucial role in addressing the capacity challenge. Open RAN promotes interoperability between different vendors, fostering innovation and competition. Network virtualization allows operators to deploy software-defined networks that can be dynamically scaled and optimized to meet changing demand. These technologies are essential for building more flexible and resilient networks.
Looking Ahead: The Future of Connectivity in Crowded Spaces
The findings from Wrigley Field, and similar tests conducted at other venues, serve as a critical reminder that **5G capacity** is not a given. The initial focus on speed overshadowed the equally important need to handle a massive influx of connected devices. The future of connectivity in crowded spaces hinges on a combination of factors: continued deployment of mid-band 5G, the adoption of private networks and network slicing, and the widespread implementation of network virtualization and Open RAN. Without these advancements, the promise of truly seamless connectivity will remain just that – a promise.
