==Later work==
In 1968, Baran was a founder of the [[Institute for the Future]] and was then involved in other networking technologies developed in [[Silicon Valley]]. He wrote on the subject of computer systems and [[privacy]].<ref name=ppaf/> Baran participated in a review of the [[National Institute of Standards and Technology|NBS]] proposal for a [[Data Encryption Standard]] in 1976, along with [[Martin Hellman]] and [[Whitfield Diffie]] of [[Stanford University]].<ref>{{cite web|url=http://www.toad.com/des-stanford-meeting.html|title=DES (Data Encryption Standard) Review at Stanford University - Recording and Transcript|year=1976|access-date=March 20, 2012|archive-url=https://web.archive.org/web/20120503083539/http://www.toad.com/des-stanford-meeting.html|archive-date=May 3, 2012|url-status=dead}}</ref>

In 1971, he predicted the development of household [[Email]].  He estimated potential revenue for such services to be $707 million by 1989.<ref name="chm-email-innovation-timeline">{{cite web |last1=Feinler |first1=Elizabeth |last2=Vittal |first2=John |date=2022-07-01 |title=Email Innovation Timeline |url=https://archive.computerhistory.org/resources/access/text/2022/08/102806104-05-01-acc.pdf |access-date=2023-08-18 |publisher=[[Computer History Museum]] |page=23 |authorlink1=Elizabeth J.

In the early 1980s, Baran founded PacketCable, Inc, "to support impulse-pay television channels, locally generated videotex, and packetized voice transmission."<ref name=ppaf>{{cite web| url=http://www.cablelabs.com/news/newsletter/SPECS/JanFeb_SPECSTECH/tech.pgs/leadstory.html |archive-url=https://web.archive.org/web/20120415014439/http://www.cablelabs.com/news/newsletter/SPECS/JanFeb_SPECSTECH/tech.pgs/leadstory.html |title=Baran's keynote on The Past, Present, and Future of Convergence |date=1999-02-09 |archive-date=April 15, 2012 |access-date=2012-03-20}}</ref><ref>Baran, "Packetcable: A New Interactive Cable System Technology," 31st Annual NCTA Convention Official Transcript, 1982, cited in US patent 4,754,426</ref> 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 [[Digital subscriber line|DSL]] modems and [[Wi-Fi]] wireless modems.

In 1985, Baran founded [[Metricom]], the first wireless Internet company, which deployed [[Ricochet (internet service)|Ricochet]],<ref name="IEEE GHN"/> the first public wireless mesh networking system. In 1992, he also founded [[Com21]], an early cable modem company.<ref name="Franklin Institute"/> After Com21, Baran founded and was president of GoBackTV, which specializes in personal TV and cable [[IPTV]] infrastructure equipment for television operators.<ref>{{cite web |title= Management Team |work= goBackTV web site |url= http://www.gobacktv.com/company-management.php |access-date= March 29, 2011 |url-status= dead |archive-url= https://web.archive.org/web/20110321031846/http://www.gobacktv.com/company-management.php |archive-date= March 21, 2011 }}</ref> Later, he founded Plaster Networks, providing an advanced solution for connecting networked devices in the home or small office through existing wiring.<ref>{{cite web |title= About Plaster Networks |work= Plaster Networks web site |url= http://www.plasternetworks.com/about.html |access-date= March 29, 2011 }}</ref>

Baran extended his work in packet switching to wireless-spectrum theory, developing what he called "kindergarten rules" for the use of wireless spectrum.<ref name=EFF>{{cite web |url=http://w2.eff.org/Infrastructure/Wireless_cellular_radio/false_scarcity_baran_cngn94.transcript |title=Keynote Talk Transcript, 8th Annual Conference on Next Generation Networks Washington, DC |first=Paul |last=Baran |date=November 9, 1994 |work=EFF "GII - NII - Wireless/Cellular/Radio" Archive |publisher=[[Electronic Frontier Foundation]] |location=San Francisco, CA |access-date=March 29, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110323202905/https://w2.eff.org/Infrastructure/Wireless_cellular_radio/false_scarcity_baran_cngn94.transcript |archive-date=March 23, 2011 }}</ref>

In addition to his innovation in networking products, he is also credited with inventing the first doorway gun detector.<ref name="Franklin Institute"/><ref name="latimes">{{cite news |author= Jessica Guynn |url= http://www.latimes.com/news/obituaries/la-me-paul-baran-20110329,0,4562265.story |title=Paul Baran dies at 84; inventor helped lay foundation for Internet |newspaper=Los Angeles Times |date= March 29, 2011 |access-date= March 29, 2011}}</ref>

He received an honorary doctorate when he gave the commencement speech at Drexel in 1997.<ref>{{cite news |title=Opportunity Lies In Ideas, Engineer Tells Drexel Grads Paul Baran, "the Grandfather Of The Internet" Spoke At His Alma Mater.
