Facebook says it has developed a laser detector that could open the airwaves to new high-speed data communications systems that don’t require dedicated spectrum or licenses.

The component, disclosed on Tuesday in a scientific journal, comes from the company’s Connectivity Lab, which is involved in developing technology that can help spread high-speed Internet to places it currently doesn’t reach.

Getting Internet signals to new areas is typically done using wireless, because it’s much more cost-efficient than running cables to communities outside of urban areas. But traditional wireless comes with speed limitations and requires radio spectrum that often needs to be purchased from the government.
