# Proptivity

> Proptivity is an independent indoor mobile infrastructure provider operating across Sweden, Norway, Denmark, the UK and Italy. We design, build and operate shared in-building systems that deliver 4G and 5G from all mobile operators through a single installation, under one agreement with the property owner. The industry term for this model is neutral host: Proptivity holds no spectrum, serves no subscribers of its own, and every operator connects on equal terms.

Key facts: around 80% of mobile data traffic is generated indoors (Ericsson Mobility Report), yet fewer than 5% of European commercial buildings have dedicated indoor mobile infrastructure (Proptivity analysis). Proptivity launched the world's first shared high-performance indoor 5G system open to every operator (Krejaren 2, Stockholm, with Fastpartner and Ericsson), delivered the UK's first high-performance indoor 5G of this kind (Folgate Building, London, with EE first live), and completed the first commercial deployment of digital operator connection, where operators connect their own baseband digitally into shared infrastructure (Haakon VIIs gate 2, Oslo, with Braathen Eiendom and Telia).
