GS2011MxxS Ultra-Low Power
802.11b/g/n Compact Module
Backwards-Compatible
The GS2011MxxS is a reduced size ultra-low power module that
provides a quick, easy, and cost effective way for device and
appliance manufacturers to add Wi-Fi connectivity to their products.
The module provides a high speed serial interface connection to an
embedded design built on an 8/16/32-bit microcontroller. The SDIO
interface can be clocked up to 40MHz.
The GS2011MxxS is an ideal solution for organizations with limited
Wi-Fi or RF expertise or for those seeking faster time to market, as it
reduces RF design time and removes the burden of testing and
certification. The module is IEEE 802.11b/g/n compliant, and meets
worldwide regulatory and Wi-Fi Alliance certification requirements.
The module includes a 12 bit analog to digital converter (ADC) for
connecting energy measurement and other sensors. It runs the full
Wi-Fi and TCP/IP networking stacks on module, completely
offloading the host microcontroller. The module supports a complete
suite of security protocols, also without tasking the host
microcontroller, including WPA/WPA2-Enteprise and Personal
security modes, legacy WEP encryption, and upper layer security
protocols such as TLS/SSL and HTTPs. Alternatively, it can be run
self-contained without a host.
For ease of provisioning, the module can be set up simply and easily
from a smartphone or laptop through the innovative Limited AP
mode or with Wi-Fi Protected Setup (WPS).
The GS2011MxxS is available with a u.FL connector to add an
external antenna for max performance or a PCB trace antenna for
low cost, and convenience while saving space. US/Canada
(FCC/IC), Europe (CE/ETSI), Japan (TELEC), and Wi-Fi certified.
