GainSpan is a San Jose, California-based semiconductor solutions company that designs and markets wireless connectivity products for the Internet of Things.[1] It offers Wi-Fi chips, software, and embedded Wi-Fi modules.[2][3][4] The company is known for providing Wi-Fi technology for the residential housing, healthcare, and smart energy industries and for its development of Wi-Fi chips that consume ultra-low power levels.[4][5][6][7] Greg Winner is the company’s president and CEO.[8][9][10] As of January 2013, GainSpan has raised $63 million in venture capital funding.[11] By the end of 2014, GainSpan was valued at just under $100m. [12]


A core group of engineers from Intel Corporation created GainSpan in September 2006.[4][8][11] The company founders wanted to eliminate the high power consumption of traditional Wi-Fi, so they developed advanced Wi-Fi chips and power saving modes.[3][6][13][14][15] GainSpan was the first company to optimize Wi-Fi chips for low power consumption and to apply new power management techniques to target long battery life applications.[5][16][17]


GainSpan develops low-power Wi-Fi and ZigBee/Wi-Fi chips and modules as well as evaluation and application development kits.[18] The company’s products, software and technology permit a wide range of devices, and appliances such as thermostats, to connect to the Internet.[19] The main products are the GS2000 Wi-Fi/ZigBee IP single chip and associated GS2011M and GS2100 modules as well as the GS1011 low power Wi-Fi SoC and IEEE 802.11b, 802.11 b/g/n and 802.11a/b/g/n dual-band certified modules.[18] Also key is GainSpan’s software which supports a suite of networking (e.g. UDP, TCP/IP, ARP, DHCP client/server, DNS client/server, HTTP(S) client/server, XML encoding and decoding for RESTful architecture support) and security protocols (WPA/WPA2-Personal or Enterprise, and SSL).[9][14][16][20]

GainSpan’s Wi-Fi chips run efficiently on memory-constrained microcontrollers due to their small RAM and ROM footprints,[2][3][17] and the chips are optimized for sensor applications where a device remains in standby mode most of the time.[20][21]
