Dear 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).

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
