The GS1550M/MD is a family of fully certified 802.11a/b/g/n Wi-Fi modules offering quick, easy and cost effective  way for  OEMs to  enable leading edge  Wi-Fi  connectivity in their  platforms.  The GS1550M/MD family consists of modules that support  either a  dual-band stamped antenna (GS1550M) or 2 dual-band external antennas (GS1550MD) to support Antenna Diversity. 

The modules provide multiple serial UART or SPI interfaces, enabling connection to any embedded design utilizing an 8/16/32-bit microcontroller via simple commands. The GS1550M/MD modules are an ideal solution for OEMs with no or limited Wi-Fi or RF expertise, as it dramatically reduces development time and eliminates the burden of testing and certification, allowing customers to exclusively focus on their core platform. The modules support Wi-Fi PHY rates up to 150 Mbps, are fully compliant with 802.11a/b/g/n specifications, meeting worldwide regulatory requirements. GS1550M/MD modules also provide support for a peer-to-peer networking capability. This feature allows Wi-Fi devices to connect to one another without an access point, enabling easy transfer of content anytime, anywhere.

The modules include access to external flash on application board, and ADC pins for connecting sensors for development of a Wi-Fi based sensor device. Multiple software configurations are available for running a stack or network services on the modules. For applications utilizing a small 8 bit microcontroller host, the modules support a serial to Wi-Fi function and run the full Wi-Fi and TCP/IP networking stacks, completely offloading the host. In addition, it supports WEP/WPA/WPA2 security, Web Server as well as Wi-Fi Protected Setup (WPS) for ease of provisioning.
