Making broadband technology more available, continuously improved, with ever advancing performance since 1987.

Making the information revolution an evolution.


I've walked into airports and libraries in over 70 countries.Anywhere in the world, there’s somebody, somehow whose life has been involved with this innovation.

Different religions, different backgrounds, different countries,but we’ve all worked together.


lancity logoMore than 30 years ago Rouzbeh Yassini, the CEO of a then-unheralded tech company began leading a 13-person team that worked tirelessly to develop the first ever commercial cable modem for cable operators.

LANcity was founded from the remnants of a company named Applitek. The LANcity team has been credited with inventing the first ever cable modem using its proprietary access technology and being an early pioneer of large scale cable modem deployments around the world. This pioneering invention would lead to cable’s historic DOCSIS Specifications.

LANcity engineers and staff helped to develop the DOCSIS 1.0 MAC specification that would ultimately usher in the global broadband era enabling multivendor interoperability that supported the deployment of hundreds of millions of cable modems worldwide and created a multi-billion dollar industry.

LANcity was the first ever company in the history of the cable industry to provide its technology royalty free to the industry and world and driving the price of a cable modem to $30 by 2010.

Distinguished Technical members of the LANcity team would later join forces with YAS Capital Partners, an organization focused on attaining affordable broadband deployment to advance the technical, economic and social transformations enabled by broadband. The company worked closely with global service providers, government agencies, private companies, educational organizations and equipment manufacturers to deploy first time innovations.

Bay Networks acquired LANcity on September 24th, 1996, for $59 million to provide global internet networking via cable. Bay Network was acquired by Nortel and then Arris inherited LANcity from Nortel.
