The Wi-Fi Comm Demo Board from Microchip Technology Inc. combines Microchip’s 32-bit PIC32 microcontroller family with its low-power MRF24WB0MA agency-certified, IEEE 802.11, embedded Wi-Fi radio transceiver module. Microchip also provides a free and full-featured TCP/IP stack, which is available for download at http://www.microchip.com/get/A3VP. This compact and cost-effective demo board is designed to be easy to integrate with existing embedded designs to evaluate Wi-Fi connectivity and 32-bit performance with minimal effort.
Microchip’s free, commercial-grade TCP/IP stack delivers all the key stack layers for a complete Wi-Fi based design. This includes HTML, DHCP, DNS, IPv4/v6, SSL, etc. In combination with the low-power Wi-Fi module and a PIC32 MCU, this stack delivers a highly optimized embedded Wi-Fi solution.
Microchip’s Wi-Fi module and TCP/IP stack enable connectivity for control and communication of the "Internet of Things" over the Internet, while its 32-bit PIC32 microcontroller family provides the performance and features to simultaneously process both Wi-Fi communications and a large number of other functions. These functions include audio, graphic displays and touch sensing, and general system command-and-control operations.
Availability and Pricing Microchip’s Wi-Fi Comm Demo Board (part # DV102411) is available for $49 at this page. Microchip’s free TCP/IP stack can be downloaded here. Ask to see the board in action at next week’s Embedded Systems Conference/DESIGN West in San Jose, at Microchip’s Booth #1116.

I tried to connect to internet by this module , but I cannot, it connects to my wireless router, but when my laptop connects to the same router, I cannot access the module, with the same Ip address.
(if it connects to the router by the DHCp and get another IP address! so what is the IP?)
WiFi was never designed to be used in battery powered smart sensor, it just consume to much power. IMHO no mather what magic they will put inside WiFi chip it will never works for more than week on battery. I can imagine that if device will once a day connect to network and send data, device will live long time on battery, but I wont call this device "smart sensor", better name will be "offline sensor". For battery powered devices like smart sensors there are better comunication networks like zigbee.
I have personally used Microchip WiFi module with PIC18F97J60. No doubt Microchip's TCPIP stack is very feature enriched, easy to use and very well organized. This board mentioned above is really cool stuff. However, I have one concern, the power. Can we run the whole thing on battery for apps like smart sensor? This thing is, though, very useful for prototyping things like handheld terminal with WiFi connectivity (in this case, the customer will not mind if asked to recharge battery on daily basis).
