I currently have a 2.4 GHz wireless camera. it is a nice camera but it interferes really bad with WIFI and Xbee.
I am looking for a wireless camera for my robot that will not interfere with Xbee or WiFi. I have heard of 5.8 GHz cameras and think I might need one of those, but as long as it doesn't interfere with Xbee it is good.

Here are m constraints.
-at least 10 FPS
- good enough quality to drive a robot
- it does not matter if it is digital or analog
- range of at least 50 meters
- preferably under $60

How about one that is wifi?

You get clones of that on eBay for less than $60. I have two of them.

Why/how do you think the cam is interfering with WI-Fi / XBee. Please provide a link to the cam you are using as I don't think you should be getting "interference". Maybe you are doing something wrong?

it sort of looks like this one http://www.amazon.com/Wireless-Micro-Spy-Camera-Complete-Package/dp/B000JCN6SW
it is analog so it does interfere with WiFi. as in my computer gets disconnected. my Xbee's only go about 10 feet when the camera is on and near the Xbees

Just use a WiFi cam then. Multiple WiFis don't interfere with each other.

what advantages would a WiFi camera provide over a 5.8 GHz camera?

The WiFi standard has built in channel negotiation, client "rules", and quality of service. You can have as many cameras connected to an AP as the AP will support, and they wont interfere with eachother or other WiFi clients. A 2.4ghz or 5.8ghz wireless camera would interfere with 2.4ghz and 5.8ghz WiFi devices.

Also, 5.8ghz has poor penetration, its going to have trouble if there is anything between the client and the AP. 2.4ghz is better if the channels are clear of other devices.

As frequency goes up, range and penetration goes down in most cases, however bandwidth capability does tend go up with frequency.

Which is one of the reasons why shortwave (single digit mhz) radio has such good range.
