Sam Heidari, Ph.D.

As VP of Engineering and later as CEO of Quantenna Communications, Inc., Dr. Sam Heidari was instrumental in building Quantenna to be a leading provider of Wi-Fi chips for carrier-class home gateways. Under his technical and operational leadership, the company developed a series of chipset solutions that enabled carriers around the world to provide video streaming services within the home. Prior to its acquisition in 2019, Quantenna was a recognized brand in the industry associating with the best WIFI experience for any application, being data or Video. Prior to joining Quantenna in 2009, Dr. Sam Heidari served as Chief Technology Officer and Vice President of Ikanos Communications, Inc. Earlier in his career at Ikanos, he served as system architect and led the systems and algorithms team which accomplished many firsts in the industry including designing world’s first 50 Mbps and world’s first 100 Mbps symmetrical VDSL product. He was very involved and influential in the standards process resulting in adaptation of DMT as the core modulation technique for VDSL. He was successful in introducing features into the standard such as lower frequency utilization as well as 8KHz tone spacing which enabled lower cost higher performance chipsets. To decide the standards, a “VDSL Olympics” was organized where each company showcased their VDSL solution based on either DMT or single carrier QAM modulation. The product that Dr. Heidari was responsible for won the best performance in this contest, leading to DMT being adapted as the worldwide standard for VDSL.
