Liga Contra El Cancer: Shadow Wifi
The Peruvian League Against Cancer needed to effectively encourage beachgoers to seek shade and protect themselves from sun exposure. Despite rising skin cancer rates, people often ignored traditional warnings. The goal was to find an innovative way to genuinely change behavior among sun-loving individuals.
Creative Idea
Free Wi-Fi was provided only to users who stayed in the shade.
To combat rising skin cancer, the Peruvian League Against Cancer launched "Shadow Wi-Fi," a free network that only works in the shade. This innovative utility provided a compelling, immediate incentive for beachgoers to seek sun protection, transforming a health warning into a desirable, behavior-changing benefit.
Chasing the Shade for High Speed Access
The Physics of the Shadow Signal
To turn a health warning into a digital utility, Happiness Brussels engineered a massive blue architectural structure equipped with a directional Wi-Fi antenna and a solar sensor. This sensor tracked the sun’s exact trajectory across the Peruvian sky in real-time. As the sun moved, the antenna rotated to beam the signal exclusively into the area covered by the structure's shadow. If a user stepped into the sunlight, the connection dropped instantly. This created a "shadow chase" effect where beachgoers at Playa Agua Dulce moved their towels and chairs in a slow-motion synchronization to stay within the Wi-Fi zone.
From Information to Incentive
Chief Creative Officer Geoffrey Hantson pivoted the strategy from traditional awareness to behavioral change. He noted that the campaign didn't just inform people about skin cancer - it gave them a functional reason to seek shade. To unlock the "reward" of high-speed internet, users first had to register on a landing page that delivered essential skin cancer prevention tips. This ensured that every one of the 250 simultaneous users was directly educated while benefiting from the service.
Open Source for Global Health
The campaign achieved a massive earned media reach of over 200 million contacts globally. Recognizing the life-saving potential of the technology, the agency and Liga Contra El Cancer made the system open-source. By releasing a "Shadow Wi-Fi" kit for any organization to download and build, the project expanded far beyond Peru into markets like San Francisco and New Zealand. This move solidified the campaign as a landmark example of Utility Marketing, where a brand solves a consumer problem to achieve a social mission.

Craft Breakdown
This campaign's craft is exceptional in its innovative fusion of physical installation, technology, and public health messaging, transforming a passive warning into an active, incentivized behavior change.
The core innovation lies in the custom-engineered solar-tracking WiFi system, which digitally connects shade provision with internet access, creating a living, interactive health intervention.
The campaign creates a highly engaging and memorable physical experience on the beach, where the product (WiFi) directly depends on the desired behavior (seeking shade), making the health message unavoidable and fun.
The design and construction of the large, eye-catching 'Shadow WiFi' structures serve not only as functional shade providers but also as bold, interactive billboards that clearly communicate the campaign's purpose.
The ingenious idea of leveraging a highly desired commodity (free WiFi) to incentivize a life-saving behavior (sun protection) is simple yet profoundly effective, bypassing traditional awareness campaigns.
The true magic of this campaign comes from the seamless synergy between innovative digital technology, compelling experiential design, and a brilliant core concept, all working in concert to drive behavioral change and health awareness.
