GS2101M Low Power, High
Speed 802.11b/g/n module
Smart Energy, Cost Optimized
The GS2101M module provides a quick, easy, and cost effective way
for device and appliance manufacturers to add Wi-Fi connectivity to
their products. Intended for smart energy and sensor applications,
the module runs the SEP 2.0 Smart Energy Profile stack and has 3
high bit-rate sigma-delta ADCs for high resolution sensor and
measurement devices.
This module provides a low cost, high speed serial to Wi-Fi
connection to an embedded design built on an 8/16/32-bit
microcontroller, achieving up to 25 Mbps throughput over an SDIO
interface.
The GS2101M 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 runs the full Wi-Fi and TCP/IP networking stacks,
completely offloading the host microcontroller. It 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/SS 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 module is single sided with castellation on the edges for the I/O
connections for soldering down on the product’s baseboard.
The GS2101M has extended range with industry leading receiver
sensitivity. It is available with an u.FL connector to add an external
antenna for max performance or a PCB antenna for convenience
while saving space. It is US/Canada (FCC /IC), Europe (ETSI) and
Japan (TELEC) certified.
