Embedded WiFi

pankeillpankeill Member Posts: 1
Hi,
We're a group of 4th year engineering students, and as our project we've gotta interface an embedded device with a 485 port via a wifi network to a master computer. there would be about 10 embedded devices which would be polled by the pc. now we've got the wifi card for the pc side, what do we put on the embedded device side? i know we've gotta put a microcontroller and some ROM, but i've got no clue about the wifi device needed. Any links or suggestions would be greatly appreciated.

Thanks,
Nikolai

    Wifi is somekind of WLAN, iirc? You will need a radio chip that can handle IEEE 802.11, preferably a pre-made module with a stack on-board. That way, you might not even need circuits with ethernet support, those modules have often got a RS-232 connection and somekind of serial protocol (like AT-commands etc). If you already have RS-485, that should suit well.

    Make sure that the module have got a good built-in antenna. You don't want to mess with that on your own: it is complicated and you will probably need to conformance-test the whole thing yet again.

    There should be loads of modules available, I know there are for Bluetooth anyway.
