Where can I get some inexpensive WiFi chips with good documentations and perhaps a development kit?

You can get 802.11a/b/g etc chips, and getting your design through WiFi qulification is going to cost you.

I assumed that a WiFi chip was the same as a 802.11 a/be/go. I'm still not clear about the distinction you're making? Where can I get 802.11a/be/go chips? Where can I find prequalified modules with documentation?

If your target volume is under 10000 to 50000, then just buy standard Wifi PCMCIA adapters (may be 20-25$ in volume). Using prism chipset based modules is easier as source code for drivers is available from Linux, as a starting point...

As a complement : If your target volume is under some hundred of units, then have a look at the Wiport solution (from Lantronix).

Once you build a product, then you can run through a set of tests and if you pass, then you can put the WiFi stamp on your product. Those tests cost money. It is difficult to get the RF part running properly without expertise, so most companies would be very reluctant in supporting you or even sell you chips.> > Where can I get 802.11a/be/go chips?> Where can I find prequalified modules with documentation?google, or ask your local friendly distributors?>-- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This message is intended to be my own personal view and it may or may not be shared by my employer Atmel Nordic AB

I'd also add this one to the list: http://www.digi.com/products/embeddeddeviceservers/digiconnectwime.jsp Never tried. No idea of cost, either.

Just the hardware took a half year to design and get through FCC testing+approval just the FCC takes from 3 months and up usually) , and there was another guy doing the firmware in parallel . I used relatively exotic and mucho expensive equipment such as a vector network analyzer, synthesised spectrum analyzer , modulation analyzer , to mention just a few. So better buy a ready made solution from China , it's just so much easier these days . best regards, Matt Tudor

Thanks for the information. It seems that one of the above solutions or a WiFi CF card might be the next step.

Digi Connect Me around 50-60 EUR While WLAN adapters (PCMCIA/PCI/USB/...) are around 20 EUR. I can accept that WiMe is clearly more expensive than high volume consumer stuff. But 8x is more than acceptable. I the space is not an issue, for 150 EUR it is possible to buy low spec SBC card with ethernet and separate WLAN HW. And you get the SBC to do the actual job.... Does anyone know of reasonably priced alternatives to Digi Connect WiMe?? Pygmi
