videotex, and packetized voice transmission." PacketCable, also known as Packet Technologies, spun off StrataCom to commercialize his packet voice technology for the telephony market. That technology led to the first commercial pre-standard Asynchronous Transfer Mode product. He founded Telebit after conceiving its discrete multitone modem technology in the mid-1980s. It was one of the first commercial products to use orthogonal frequency-division multiplexing, which was later widely deployed in DSL modems and Wi-Fi wireless modems. In 1985, Baran founded Metricom, the first wireless Internet company, which deployed Ricochet, the first public wireless mesh networking system. In 1992, he also founded Com21, an early cable modem company. After Com21, Baran founded and was president of GoBackTV, which specializes in personal TV and cable IPTV infrastructure equipment for television operators. Most recently, he founded Plaster Networks, providing an advanced solution for connecting networked devices in the home or small office through existing wiring. Baran extended his work in packet switching to wireless-spectrum theory, developing what he called "kindergarten rules" for the use of wireless spectrum. In addition to his innovation in networking products, he is also credited with inventing the first doorway gun detector. He received an honorary doctorate when he gave the commencement speech at Drexel in 1997. Death Baran died in Palo Alto, California, at the age of 84 on March 26, 2011 from complications caused by lung cancer. Upon his death, RAND President James Thomson, stated, "Our world is a better place for the technologies Paul Baran invented and developed, and also because of his consistent concern with appropriate public policies for their use." One of the fathers of the Internet, Vinton Cerf, stated, "Paul wasn't afraid to go in directions counter to what everyone else thought was the right or only thing to do." According to Paul Saffo, Baran also believed that innovation was a "team process" and avoided seeking credit for himself. On hearing news of his death, Robert Kahn, co-inventor of the Internet, said: "Paul was one of the finest gentlemen I ever met and creative to the very end."
