Dual-band Wi-Fi modules

23 January 2013 Telecoms, Datacoms, Wireless, IoT

New from GainSpan is a dual-band 802.11 a/b/g/n Wi-Fi solution that utilises both the 2,4 GHz and 5,0 GHz spectra, enabling customers to access cleaner spectrum for applications requiring relatively interference-free bandwidth.

The new GS1550M/MD family provides reliable wireless connections, particularly in challenging environments such as healthcare facilities and industrial applications.

The new product family 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 modules feature two UART and SPI interfaces for ease of integration with any 8/16/32-bit microcontroller, and come preloaded with serial to Wi-Fi firmware for communication with the MCU and complete Wi-Fi functionality.

They offer advanced networking features and capabilities such as 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, and more.

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. They provide support for peer-to-peer networking, allowing devices to connect to one another without an access point.

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