Company Details


GainSpan brings Ultra-low-power Wi-Fi to sensors and embedded applications. The company's semiconductor solutions break new ground in Wi-Fi applications by enabling years of battery life for Wi-Fi sensors and other devices.

In September of 2006, a core team of engineers and thought leaders spun off from Intel Corporation to form Emphany Systems, later GainSpan. The vision was simple... enable and accelerate the adoption of new wireless usage models for sensor network applications using an existing widely deployed standard technology.

The challenge was daunting... while wireless sensor networks have seen steady growth over the past few years, their market potential has, in fact, been hindered by power consumption issues and lack of mature standards based solutions.

The solution was innovative... new Wi-Fi semiconductor and software solutions that enable sensors and other devices to run up to 10 years on a single AA battery. This allows users to leverage the global Wi-Fi infrastructure, existing tools and knowledge investments, for new applications such as temperature monitoring for energy management, condition monitoring of industrial equipment in manufacturing plants or streetlights in metro areas.
