Redpine Signals was a fabless semiconductor firm established in 2001, focusing on the development of chipsets and integrated system products tailored for wireless networking. The company primarily served the markets of wireless embedded systems and the Internet of Things, catering to various production scales of chipsets and modules.

In 2005, Redpine created a low-power 802.11 b/g chipset that was licensed to a semiconductor manufacturer for incorporation into its SoC wireless solutions. By 2007, the company released a single-stream 802.11n Wi-Fi product designed specifically for handheld devices. Later, in 2012, Redpine launched a simultaneous dual-band Wi-Fi 11n/BT 4.0 combined with a 5 GHz MIMO 11ac SoC aimed at smartphones and tablets. Additionally, it introduced a simultaneous dual-band 450 Mbps 3x3 802.11n chipset targeting digital home and enterprise sectors.

In 2020, Silicon Labs acquired Redpine’s connectivity division, which included its Wi-Fi and Bluetooth product lines, the Hyderabad-based development center, as well as its portfolio of patents.

Products and services

Redpine Signals provided single-stream 802.11abgn chipsets and modules alongside system-level products designed for Wi-Fi based Real-Time Locating Systems (RTLS). Their 'Wi-Fi Starter Kits' integrated Redpine Wi-Fi interface cards with microcontroller development kits through strategic partnerships.

In 2013, the company introduced chipsets and modules supporting multiprotocol Wi-Fi, dual-mode Bluetooth 4.0, and Zigbee technologies aimed at IoT devices and handheld market segments.

Support for certain rsi91x hardware is available via an open-source Linux kernel driver utilizing the mac80211 framework, improving interoperability within wireless environments.

The firm also delivered a comprehensive IoT platform that encompassed hardware boards, application development tools, cloud software solutions, service frameworks, and product synthesis capabilities. This unified platform expedited market entry by integrating sensing, computing, communication, power management, cloud infrastructure, and application support components.
