GainSpan has released a dual-band 802.11 a/b/g/n Wi-Fi solution that uses both the 2.4 and 5.0 GHz spectrum, enabling users to access cleaner spectrum for applications requiring relatively interference-free bandwidth.

The GS1550M/MD family provides wireless connections for challenging environments such as healthcare facilities and industrial applications. The solution provides a way for manufacturers to add dual-band wireless capabilities.

The range consists of two modules: the GS1550M which supports a dual-band stamped antenna, and the GS1550MD which supports two dual-band external antennas for antenna diversity. The antenna diversity is said to enhance signal coverage.

The range features two UART and SPI interfaces for ease of integration with 8/16/32-bit microcontrollers and comes preloaded with serial to Wi-Fi firmware for communication with the MCU and Wi-Fi functionality.

The modules provide networking features and capabilities not readily available with other Wi-Fi modules, including easy provisioning from a smartphone or web browser, over-the-air firmware updates, personal and enterprise wireless security, embedded DHCP, DNS and HTTP(S) servers/client software, XML parser, advanced mDNS/DNS-SD based device and service discovery.

The modules support data rates up to 150 Mbps, can operate in infrastructure or Limited AP mode and are fully compliant with 802.11a/b/g/n specifications. The modules provide support for peer-to-peer networking, allowing devices to connect to one another without an access point. The modules will be fully certified for major worldwide regulatory regions.

With both a sleep and deep sleep option, the modules can be put to sleep to reduce power consumption without loss of data and can then recover from the deep sleep state back to full operation. The modules also support a very low-power standby mode, which reduces power consumption to a few microamperes.

The range is pin-and-footprint compatible with the company’s GS1011M and GS1500M modules. The GS1550M/MD modules are single sided and designed so they can be soldered down on application baseboards.
