Headquartered in San Jose California, Redpine Signals is a wireless systems company with unique chipset and system level products for wireless networks. Founded in 2001, Redpine has created advanced wireless technology that has gone into the creation of ultra low power and high performance products for the next generation wireless applications. Redpine was the first in the industry to launch a single stream 802.11n chipset in late 2007. Subsequently, it has launched several modules and sub-systems focusing on specific vertical market segments including industrial, wireless sensor, wireless audio & video, voice over Wi-Fi and high end consumer. In 2009, it has launched modules and subsystems that enable the wireless monitoring and control of utility metering systems. It also offers MIMO 802.11n as well as mobile WiMax (802.16e) and 4G LTE technologies.

Redpine technology spans the complete end-to-end wireless solution and includes an extensive patent portfolio on OFDM, MIMO, embedded processor architectures and low-power techniques. The company's offerings include both the hardware and the software as differentiated sub-systems to provide flexibility and ease of integration to the system integrator. This single-stop approach enables Redpine to deliver an optimal wireless solution to meet customer's requirements at an optimal price point.

Redpine's team of industry veterans is focused on expanding the wireless horizon into new markets by delivering the cutting edge ultra low power wireless solutions optimized for these vertical market segments.

Culture of Innovation
The most important metrics of a wireless solution are: Cost, Power-Consumption and Performance (Rate/Range/Multipath). Wireless solutions developed by various companies have been known to compromise on one metric to gain on another: Solution-I may have succeeded in being the best in throughput and range, but it has taken up a major amount of silicon real-estate to achieve that. Solution-II has concentrated on optimizing for silicon-area but ended up with low data-rates and range performance. Solution-III has compromised on all three metrics to some extent and ended with ‘average’ metrics on each of these.

Redpine was founded in 2001 by industry veterans with a vision to build a company with a culture of innovation. From the first day, Redpine’s main thread and differentiation has been our endeavor to “Expand the Wireless Horizons”. Redpine has spent more than 600 man-years in research and innovation into next-generation Wireless technologies based on OFDM and MIMO, resulting in over 100 patents, patent filings and disclosures. Today Redpine’s solutions have industry leading performance, cost and power-consumption – all in a single product. The “Culture of Innovation” is core to Redpine’s solutions being at the top of the wireless pyramid.

Redpine's Leadership
Busting the myth on performance vs power: High Performance "is" low energy!!

Redpine has consistently taken advantage of the fact that energy efficiency (kilobytes of data transferred per mJ of energy consumed) is higher in high performance systems. Redpine’s wireless solutions are robust to multipath, and use advanced patent-pending MIMO decoders, STBC, and Beamforming; and effectively deliver higher data-rates at any location – be it an airport or an industrial work-shop. Operating at a higher data-rate means that packet durations are smaller. Therefore, the “power-hungry” radio and power amplifier are turned-on for less time. This fact, combined with intelligent power-management of the wireless chip and system components, means that overall less energy is used up in getting the same amount of information across. This is clearly the future path where the same solution can deliver both low-power and high-performance and uses the minimum energy for any given user bandwidth requirement.
