In Greek mythology, Idas was a son of Aphareus and Arene and brother of Lynceus. He and Lynceus loved Hilaeira and Phoebe and fought with their rival suitors, Castor and Polydeuces, killing the mortal brother Castor. He was also one of the Argonauts and a participant in the hunt for the Calydonian Boar. He kidnapped Marpessa. Apollo also desired her and Zeus made the girl choose. She chose the mortal Idas, fearing that Apollo could abandon her when she grew old. With Marpessa, Idas had one daughter named Cleopatra.

A distributed antenna system, or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level and node installations are compact. A distributed antenna system may be deployed indoors (an iDAS) or outdoors (an oDAS).
