Engineers at Facebook’s Connectivity Lab have developed a large laser detector that could help deliver Internet to new areas by opening “airwaves to new high-speed data communications systems that don’t require dedicated spectrum or licenses,” reports PC World. Reaching new regions typically involves cost-efficient wireless networks, which also require radio spectrum and often have speed limitations. Instead, engineers are looking into “sending data from point-to-point over laser beams” that would not involve “any special spectrum or permission, and multiple systems can work in the same area without interfering with each other.”
