Wireless Digital Transmitter/Receiver for connecting two FPGA boards.

I am trying to connect two FPGA development boards together and am wondering does anyone know of any products that might suit. The boards in question are two Celoxica RC100 development boards. Video in is from an analog camera. The video data is converted to digital and stored on SRAM. There is an expansion header for inter-connectivity. On the other board video out to a monitor occurs after reading data from the SRAM on this board. Have connected to two boards via a ribbon cable connected to the expansion headers. Want to replace this cable with wireless or optical transmission. Is there any development boards available for this. The pixel clock is 10 MHz and there are at least 16 bits per pixel (32 aftere error correction encoding). Access to a 80 MHz on board clock is available. Any help would be much appreciated.

Tricky. You appear to need a 320Mbit/sec data rate.

It would be easier to put the wireless link between the camera and the Celoxica board.

You can get cheap Video Senders that operate on the 2.4GHz band but they will probably cause problems for any 802.11b wireless LANs you may have.

The fact I need a 320 Mbps data rate is a major problem. I can't find anything that suits. Unfortunately I can't use a wireless camera as my project is to test error-correction codes. The system will be camera

-> Fpga-based error-correction Encoder -> Transmitter at one end of room and Receiver -> FPGA-based decoder -> Monitor at other end of room. Only need to transmit over max bout 5 m. Theres no WLAN in area so won't interfere with them, thats not a problem. An optical or infrared (IR) system seems best bet. Any ideas of how to set one of these up.

Hi, if you want to test error correction codes you don't need the wireless transmission. Connect your boards with coaxial cable. Additional attenuators may substitute path loss. A noise generator may be coupled in, too.

Yes I agree with that.

It's a lot easier and cheaper to find a calibrated "noise generator" for coax than it is for a wireless system.
