Rain Wi-Fi. The world’s first rain-powered 4G-router

The campaign was aimed at residents of St. Petersburg who actively use mobile internet. Research helped Tele2 identify local insights that are particularly relevant to the people of St. Petersburg:

Many historic buildings have courtyards that do not receive any mobile internet signal.
Additionally, the city is very humid, with 200 rainy days per year in St. Petersburg.
Residents often have to hide from the rain in these old courtyards without being able to use mobile internet. Tele2 took into account that their target audience cannot live without mobile internet and installed their 4G generators where other mobile operators do not have coverage.

The system works quite simply: the device is installed in the rain gutter, then the rainwater activates a turbine that generates electricity, and the 4G router provides Wi-Fi. The technology will be patented (Application No. 309515310).
