GainSpan sampling Wi-Fi/ZigBee chip for IoT and other applications

The GS2000 wireless IC from GainSpan integrates both Wi-Fi (802.11b/g/n) and ZigBee IP (802.15.4) transceivers. The GS2000 is designed for smart home, smart Energy, e-metering, medical electronics and high-speed audio, video and electronic security applications.

In today's wireless environment, Wi-Fi is widely used in consumer mobile wireless, and ZigBee is used in the industrial electronic industry for its low-power consumption. If a wireless integrated embedded/electronic system designer wish to use both Wi-Fi and ZigBee as wireless interface options, here is a single chip supporting both Wi-Fi and ZigBee.

The GS2000 supports both IPv4 and IPv6 devices and is powered by dual ARM Cortex -M3 processors and is provided with networking stack and services. This chip also boasts of having large memory size to support various application profiles. It supports Wi-Fi WLAN software, ZigBee IP, which is based upon 6LoWPAN and IP based addressing and methods over both 802.11 and 802.15.4 wireless standards. This wireless chip supports applications without any microcontroller as host allowing to use 8 /16 bit microcontrollers as well as with 32 bit MCU.

GS 2000 support Station/Client Mode, Limited Access Point, Wi-Fi Direct, and Wi-Fi Direct with concurrent mode.
Other features include:
802.11 b/g/n chips and modules with multi Mbps throughput over SDIO, SPI or UART
Low idle power consumption with fast wake up
High receiver sensitivity capability
Extensive networking stack and services
Personal and enterprise security, embedded DHCP, DNS and HTTP(S) clients and servers, XML parser, service and device discovery, easy provisioning, and OTA firmware updates
Supports SEP2.0, OpenADR and ECHONET Lite for Smart Energy

What is missing in this chip is lack of support for Bluetooth, which is also popular wireless interface standard.
