Skylo was founded to bridge coverage gaps allowing standard cellular devices to transmit signals via satellite when out of range of traditional cell towers. Skylo's NB-NTN Mobile Satellite Service (MSS) provides network components that seamlessly extend the cellular experience, ensuring continuous coverage if devices have a clear view of the sky. Skylo offers a real-time 24/7 direct-to-device (D2D) service spanning five continents, authorized in 41 countries, covering over 75 million square kilometers with more than 18 million activations.
Skylo's service utilizes existing satellite infrastructure, primarily geostationary (GEO) satellites, though it is also compatible with low earth orbit (LEO) satellites. This D2D NB-NTN service is compatible with 3GPP Release 17 standards (and beyond) and operates over dedicated, licensed MSS L- and S-band spectrum, enabling standard mobile phones, wearables, and Internet of Things (IoT) devices to connect directly to satellite infrastructure.
Skylo has various business models for service provision: it works directly with Mobile Network Operators (MNOs) such as Verizon, Vodafone, Orange, Deutsche Telekom, Telefonica, Tele2, Charter Communications, and Comcast, or with original equipment manufacturers (OEMs) such as Google and Garmin.
Skylo's customers focus on the provision of emergency and safety services to end-users. In an emergency such as flooding, wildfire, severe storm, maritime, backcountry, or automobile accident, affected users of a Skylo OEM partner can connect to an emergency response center which then coordinates with a government-designated search and rescue center to determine which local entity would manage the emergency response. Device manufacturers generally provide emergency satellite service as a feature of the phone free of charge. In an MNO-led model, affected users can directly message their personal contacts using the Skylo NB-NTN service when outside of coverage areas to seek emergency assistance or simply to maintain contact.
By operating over standardized 3GPP Release 17 NB-NTN cellular modems, which incorporate MSS frequency bands, Skylo benefits from economies of scale. This reduces deployment costs compared to traditional satellite phones, which are often based on proprietary technology and more limited in scale, and therefore more expensive. Skylo's adherence to 3GPP standards ensures interoperability with the existing terrestrial mobile ecosystem, allowing satellite and terrestrial mobile services to function seamlessly, similar to standard roaming today. Additionally, since Skylo utilizes existing GEO satellites in MSS spectrum bands, no new capital-intensive expenditures are required, simplifying the regulatory framework and providing a more cohesive and user-friendly experience for individuals and businesses alike.
