GS2011M Ultra-Low Power
High Speed 802.11b/g/n Module
Backwards-Compatible
The GS2011M is an 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
at up to 40MHz.
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-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 GS2011M is available with an u.FL connector to add an external
antenna for max performance or a ceramic chip for convenience
while saving space. US/Canada (FCC/IC), Europe (CE/ETSI), Japan
(TELEC), and Wi-Fi certified.
BENEFITS:
