GainSpan's GS1500M module achieves Wi-Fi Direct certification

Supplier News
The low power GS1500M 802.11 b/g/n Wi-Fi module by GainSpan Corporation has achieved Wi-Fi Direct certification from the Wi-Fi Alliance.

Wi-Fi Direct allows devices to communicate directly with each other without having to connect first to an access point, thus enabling many new wireless device-to-device applications and usage models.

Using a GS1500M Wi-Fi device with underlying Wi-Fi Direct mechanism, one can discover and connect a camera to a printer, a sensor to a display or a remote controlled device to one or more smartphones without an access point.

Even multiple devices can be connected at once in a one-to-many configuration making it simple to print, display or share content with multiple devices in a peer-to-peer relationship, even in the absence of a Wi-Fi access point. Wi-Fi Direct allows devices to automatically discover, negotiate and connect with other devices in the vicinity without user intervention. With Wi-Fi certified technology, users get industry-standard interoperability and security.

Wi-Fi Direct extends the GS1500M Wi-Fi module's mode of operations, which already includes Limited Access Point, and client of an existing infrastructure network (Client/Station Mode). With Limited AP mode, GainSpan offers the capability to act as a soft access point connecting several Wi-Fi client devices and supporting packet forwarding between these devices.

Wi-Fi Direct further improves the user experience by eliminating the need to setup a wireless network with an access point and having clients connect to the Access Point, thus providing a faster and easier way for devices to connect and communicate with each other. It uses the intrinsic capability of Wi-Fi Protected Setup, which eliminates the need for a passphrase and uses either the pin or push button method, while still being protected by WPA2 security.

Key features of GS1500M Wi-Fi modules:

  • High-performance 802.11 b/g/n Wi-Fi module
  • Allows easy integration with most 8-32 bit microcontroller (MCU) based solutions
  • Enables embedded designers to quickly add Wi-Fi connectivity through a serial interface and using AT commands
  • Advanced networking features including enterprise security, embedded servers, service and device discovery, XML parsing, and over the air firmware upgrades
  • Also certified for Wi-Fi Protected Setup
