PRODUCT BRIEF
GS2011M Low Power , High
Speed 802.11b/g/n Module
Backwards-compatible
The GS2011M module 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, achieving up to 40 Mbps throughput over
an SDIO interface.
The GS2011M 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 two analog to digital converter (ADC) pins 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-Entep
rise 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).
