Hi!, your project worked? have you been able to achieve speeds greater than 1mbps?
I´m in a similar project, i need to transfer high quality audio trough wifi...
I would like to know your experience...
Thanks!Posted 10 months ago #
sorry for the late response, we had various difficulties with this WiFi thing so we put it aside for the moment.
It would be really hard to read in a camera module fast enough on a microcontroller, consider a possibly needed compression or encoding of this video/frames and eventually transmit all this data at a acceptable speed over WiFi to a base station or end device.
For this process, each component in our system should be really fast. However, a video stream isn't our main objective of our quadrocopter. It's much more important to ensure a stable connection between the quadrocopter and an end device, which transmits RC signals and other control information.
Therefore we decided to separate the video transmission and our control signals. By now, we are focusing on the RC signal transmission over XBee. XBee also uses the 2.4 GHz frequency band, but compared to WLAN it is much easier to handle and is also suitbale for longer distances (up to 1.6 km with XBee Pro), which is very useful for a quadrocopter. ;)
Our XBee module works fine, we are able to steer our quadrocopter from a desktop PC wirelessly.
For the camera, we are using a easy all-in-one solution from HobbyKing (http://www.hobbyking.com/hobbyking/store/__22824__2_4GHZ_100mW_Tx_Rx_1_3_inch_CCD_Camera_PAL_520TV_line_.html).
At the moment, we are still improving our client- and µC-programs.
Well, especially in the last few weeks we thought about a base station with WiFi capability. So, we would have:
Quadrocopter <--XBee--> Base Station <--WiFi--> PC / smartphone / webserver / ...
This would make it possible to control the quadrocopter with multiple devices.
I'm still looking for the best WiFi solution. As i mentioned in earlier posts I would go with the RN-171 or RN-131 from Roving Networks / Microchip (http://www.microchip.com/pagehandler/en-us/technology/wifi/products.html). The datasheet says that it could handle up to 2 Mbps.
It still will a take a few weeks or even months to finish this whole project and this WiFi possibility. I will remind me to keep you up to date with any results, according to this WiFi modules.
