Product Overview
The GS2011M low power based module provides cost effective, low power, and flexible
platform to add WiFi connectivity for embedded devices for a variety of applications, such
as wireless sensors and thermostats. It uses GS2000 SoC, which combines ARM
® Cortex
M3-based processors with a 802.11b/g/n Radio, MAC, security, and PHY functions, RTC
and SRAM, up to 4 MB FLASH, and on board and off module certified antenna options.
The module provides a WiFi and regulatory certified IEEE 802.11b/g/n radio with
concurrent network processing services for variety of applications, while leverage existing
802.11 wireless network infrastructures.
GS2011M Module Product Features
• Family of modules with different antenna and output power options:
• GS2011MIx 22.8mm (0.90in) x 32.5 mm (1.28in) x 3.63mm (0.143in) 48-pin
PCB Surface Mount Package. Two SKU’s are:
– GS2011MIZ (on-board antenna)
– GS2011MIE (external antenna)
• The two SKUs are pin to pin compatible, and the user has to account only for
power consumption, and on-board antenna keep out (if used) to accommodate
“one size fits all” for various end applications.
• Simple API for embedded markets covering a large range of applications
• Fully compliant with IEEE 802.11b/g/n and regulatory domains:
– 802.11n: 1x1 single stream, 20 MHz channels, 400/800ns GI, MCS0 – 7
– Data rates of 7.2, 14.4, 21.7, 28.9, 43.3, 57.8, 65.0, 72.2 Mbps
– 802.11g: OFDM modulation for data rates of 6, 9, 12, 18, 24, 36, 48 and 54
Mb/s
– 802.11b: CCK modulation rates of 5.5 and 11 Mbps; DSSS modulation for
data rate of 1 and 2 Mbps
