Icarus 
Hi, Need to integrate WiFi (min 5mbps) on mini2440. Would prefer not to block the USB port, so I guess usb wifi dongles are out. Got some other USB devices to use with the 2440. The WiFi modules (SPI/SDIO/UART i'face based) available, seem to be at-least $35 (for 20units or more). However, it is strange that for about same (or bit less), I can buy a wireless-router these days, at single-unit retail. I must be missing something here!!! Oh did I say that I have a MediaTek chipset based Shenzai phone with both GSM and WiFi module capabilities, bought retail, for just a little more :-) Of course, these people buy in 10k unit volumes (or more, I am guessing), but still, the WiFi module prices don't seem to make sense. I did find some 2.4GHz transceivers with inbuilt 8051 MCU & ADC, available for about $3, but I think we are missing the entire WiFi stack. Anyhow, given the typical BOM (as evident from some teardown reports), such a module should be available in $15 range, but I find nothing of that sort. ~Icarus.
