will two 2.4ghz signals interfere with eachother?

collin christine E asked:


I’m working on a project that involves a 2.4ghz xbox 360 controller and a 2.4ghz wireless surveillance camera operating very close to eachother.

Will the two effect each other because they operate on the same frequency or will they not because one is an A/V signal and one is a controller data signal?

I know that it wouldn’t be an issue with a 1.2ghz camera, but the range isn’t as good.

    Yes they will interfere with each other. That the signals are different, doesn’t change the fact that they are on the same frequency.
    You could speak english, and another spanish, but if your cell phones had the same channel/frequency, don’t you think it would still interfere?
    This is the same thing.
    It’s the same reason that RC car owners have a box of radio crystals, so they can change channels when running next to each other.

    Well the answer is yes and no. it depends on the technology u are using. 2.4 gig band is actually divided into several channels. so if the channel used by ur x box and ur camera are different then they wont interfere. there is one more possibility that you are using a common router for both of them. In that case this problem can easily be solved by just changing the channelfrom ur router…..

    While they are both on 2.4 GHz that is actually a band of channels. Therefore there are multiple channels available. I wasn’t able to find any details about how the Xbox works, other than hints that it is “like bluetooth but better, that is is still on when the controller is off, and that the signal jumps around over the band. The link below hints that some people have had problems, and others haven’t. This is speculation. The only way to know for sure is to try it.

    Don’t know what your project is, but this may help if the interference is an issue. There are stand alone WIFI boxes with serial port outlets that are handy for remote control from a WIFI network or as a WIFI point to point network. They could be controlled from a PC somewhere on the network. Communication is through your own software on the PC, using messages as if for ethernet. At the remote end, you need to receive and interpret the message as an RS232 signal.
