I plan to integrate my data acquisition devices to WLAN.
Could you recommend easy to use and low cost chip/chipset
for using with microprocessors?
Where to start with it?
Any low-cost development kits exist?

Regards

Hi Sobakava,
I dont know the part number and prices of these chipsets. But these are the companies who sell most of the WLAN chipsets.. (include agere too). May be rest of the details like price.. you can enquire to the local distributors in your place.

Hi,
If you need wireless only, you can try nrf24xx from www.nvlsi.no . If you need wlan, I think it is better to use a pcmcia card, especially if you work with small qty. I had a bad experience with building wlan sollution starting from chipset, 4 years ago, with prism 2 from intersil. The chipset was not expensive, around $40, but all the project went down when I realised that I have to purchase few rf critical components (saw filters, non-standard value rf coils, etc.) in big qt'ies (thousands). And another issue is writing firmware inside the MAC controller of the chipset, to comply with 802.11 .

Best,

I donnot have links, but I don't think that using PCMCIA card is an impossible task. It was an idea, it is easier to use a pcmcia card already built than to design an entire 802.11 sollution.

An ODM helps us to design a mini pci 802.11 card using atheros chip set. It takes 6 months (with > 1 engineers) to get the wifi approval but it is still full of bugs. Now a wlan card (11a/b/g) is cheap and widely available. I don't suggest you design your wlan card. Instead I suggest you buy the card either PCMCIA or minipci, add a software driver and integrate to your device.

1. Full datasheets and firmware with documentation of WLAN chipsets( 802.11g compatible ) from
w*w.atheros.com

2. I want to chage the MAC layer and control the PHY layer through my code. So all tools required for this will also be needed.

You have ?
