LANcity was an early pioneer in cable modems, developing a proprietary system that was widely deployed in the U.S. LANcity, which was led by the Iranian-American engineer Rouzbeh Yassini, was then acquired by Nortel, which eventually spun the cable modem business off as ARRIS.
He was the founder of LANcity and helped establish the cable modem industry standard (DOCSIS) through Cable Television Laboratories.
