About Rayspan

Rayspan Corporation, founded in 2006 by Dr. Maha Achour, operated from San Diego, California, as a developer of wireless air interface solutions. Dr. Achour, who also served as the Chief Technical Officer, leveraged her expertise to pioneer developments in metamaterial technology for wireless communications. The company aimed to address the market for cellular handsets, WiFi routers, and modems by providing technology that enhanced wireless performance.

The core of Rayspan's business was the development and potential licensing of its proprietary metamaterial air interface solutions. This technology was designed to enable the creation of ultra-compact, multi-band, and multi-mode antennas and RF front-end components. The primary benefit for clients, such as manufacturers of WLAN devices and cellular handsets, was the ability to achieve superior communication speed, range, and mobility at reduced costs and with easier manufacturing processes. Rayspan's solutions supported a wide array of wireless applications, including WiFi, 2G/3G/4G cellular, Bluetooth, and GPS.

Throughout its operation, Rayspan secured significant financial backing from prominent venture capital firms. The company raised a total of $25 million, which included a Series B funding round of $12.5 million on July 27, 2009, led by Khosla Ventures and Sequoia Capital. By 2010, the firm had built a substantial intellectual property portfolio with over 125 awarded and pending patents, covering its fundamental metamaterial structures and their application in communication systems. Despite these technological advancements and financial support, the company eventually ceased operations and is now considered deadpooled.
