GainSpan Embedded WiFi Technology


The Smarter Things We Do to Make Wi-Fi Ultra Low Power...and Better

Wi-Fi Chip

As a wireless innovator, 'Getting Connected with Wi-Fi' is not just our tag line, but our vision for the future. Our technical advances - a result of years of accumulated experience in supporting customers - are all designed to make Wi-Fi technology the choice for the Internet of Things. And we/'ve done just that.

Our Wi-Fi technology solves the low power consumption problem - once and for all.

When it comes to optimizing Wi-Fi power consumption, GainSpan leads the way. We offer the lowest power Wi-Fi solution on the market today - bar none!

The low power is the result of patented technology and a properly architected chip in combination with software techniques and algorithms to optimize power consumption and wake up time.

All of this came about after working with hundreds of customers who were designing products that needed long battery life. Fundamentally, our low power Wi-Fi 'sleeps' better and 'wakes up' faster than anyone else's Wi-Fi. Let us explain the various components that are necessary to achieve this unprecedented level of low power consumption:

  • Better Sleep States
  • We have many low power states, with excellent statistics in each one. For example, our standby/deep sleep current - as low as 260 nA in certain conditions - is comparable to the best.

  • Faster Wake-up
  • We wake-up faster from these low power states than other Wi-Fi chips. Our wake-up time is just one or two milliseconds.

  • Accurate Timing Circuitry and Algorithms
  • We've optimized these such as to wake up as close as possible to a beacon and leave the receiver on as little as possible.

Our Wi-Fi technology can work with even the most resource-constrained MCUs!

GainSpan Wi-Fi offers the most integrated and extensive networking stack. It can be paired with very small, low cost 8-16 bit MCUs with limited capability, or with larger 32-bit MCUs/ MPUs if required by the application. It can even be paired with no MCU at all - something no one else can do.

GainSpan's Wi-Fi is of particular interest for Internet of Things devices because it's truly a 'system-on-chip' combining baseband, RF, memory and two processors: a WLAN processor running the Wi-Fi MAC and a network service/ application processor. The networking stack and services are hosted on the second processor, offloading the host MCU used in the device.

The networking stack supports dual mode IPv4/IPv6 TCP/UDP along with additional networking services: personal and enterprise security, embedded DHCP, DNS and HTTP(S) clients and servers, XML parser, and service and device discovery. And it supports SEP2.0, OpenADR as well as ECHONET Lite for Smart Energy Applications.

With low-power MCUs increasingly serving as the processing engines behind today's Internet of Things devices, and hostless devices (i.e. door locks, smart plugs, garage door openers) gaining traction - the flexibility provided by this fully embedded stack is becoming more and more critical.
