GS2100M L ow Powe r, High
Speed 802.11b/g/n module
Smart Energy, Cost Optimized
The GS2100M 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 40 Mbps throughput over an SDIO
interface.
The GS2100M 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 me ets
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 GS2100M has extended
range with industry leading receiver
sensitivity. It is available with a 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.
