Ben Horwath

Ben Horwath has over 10 years in the communications industry in engineering, sales/marketing, and as an entrepreneur. Ben holds a Bachelor’s Degree in Chemical Engineering from Pennsylvania State University, a Master’s Degree in Electrical Engineering from Santa Clara University, and is currently working towards his Ph.D. Degree in Electrical Engineering at Santa Clara University.

Ben began his career with Corning Incorporated, leading process and equipment projects at Corning’s international optical fiber manufacturing sites, and eventually oversaw manufacturing capacity and project planning to balance Corning’s global supply and customer demand. Ben later joined Phaethon Communications as a Systems Engineer where he was a key member of the product development, sales, and marketing teams, developing product requirements for a tunable dispersion compensator while managing 30 optical networking OEMs (including Cisco, Nortel, Lucent, BigBear, Ciena, Fujitsu, Huawei, and Agilent).

Wearing an entrepreneurial hat, Ben founded AirRay Systems based in Palo Alto, CA and led all strategic planning, systems design, and business development efforts. AirRay’s goal was to implement blind adaptive beamforming algorithms for extending range, throughput, and battery life of Wi-Fi devices. Ben spent much of his time developing the DSP software prototype in MATLAB and Simulink, integrating AirRay’s proprietary algorithms and beamforming framework within the IEEE 802.11 architecture.

Ben is currently researching smart antenna hardware designs for mobile devices as a Ph.D. student under Dr. Talal Al-Attar at Santa Clara University. The research will focus on analog devices and DSP algorithms for realizing adaptive antenna arrays in handheld wireless communications devices. Applications for this technology include 3G/4G broadband, wireless video, RFID, and robotics and satellite communications.
