They can.
Microwave ovens and 802.11b network devices also share the same frequency range.
I switched to a 900Mhz phone to eliminate interference I was getting from my 2.4G video sender and my old 2.4G phone. I still use the video sender, but if someone uses the microwave oven, it scrambles the signal.
Hope that helps.

What if I use a 900MHz video sender? I have a 2.4GHz phone and would rather not get rid of it. I don't have a 900MHz phone so that shouldn't be a problem. Anybody have any experience with these?

Brian, I could be wrong but I think those video senders only come with 2.4GHz. I haven't seen anything with 900MHz. Also, with 2.4GHz, you have better bandwidth than 900MHz (i.e. better quality). I had one before and it worked fine as long as I don't use microwave oven.

Why would the bandwidth change with a lower carrier frequency? A TV channel at 54 MHz has a 6MHz bandwidth, and a TV channel at 734MHz has a 6MHz bandwidth. I don't see why the quality would be lower.

Anyone know why I would get interference with the sound only on my XCam2? The picture comes in great, just a loud hum though. I finally disconnected one of the speaker rca plugs . . . no sound was better than the hum.
I also experience picture interference when the microwave was in use.

I saw a 900MHz model on smarthome.com. They also have a 2.4GHz model which they claim will have no interference with other 2.4GHz devices because it can switch channels. Is that true?

A guy at work can't use his X-10 (2.4 GHz) video sender with a Siemons (spelling?) 2.4 GHz wireless phone because of interference. I think the degree of interference varies depending on the type of wireless phone. I think he said the video has lines across it. I'll ask him tomorrow if that's not right. Anyway, there really isn't any real way of telling what 2.4 GHz equipment will work togeither except to try it and get it returned real quick if it doesn't. There are not FCC standards that make everyone play nice. 2.4 GHz is really a free-for-all frequency spectrum.

"I also experience picture interference when the microwave was in use."
A microwave oven is just an oscillator (magnetron) operating around 2.4GHz...a 600 to 1000 Watt oscillator! Expect interfearance. As a side note....those who do experience interfearance from a microwave oven must realise that it means microwaves are obviously 'leaking' out of your oven...it's supposed to be a sealed waveguide type chamber.

I still have an old 900Mhz A/V sender that I got from a discount store many years ago. It would work, but there were so many other devices using the 900Mhz range (an older wireless phone, some RF controlled toys, etc..) that I always got irritated by the interference. It's range wasn't much, especially if there was more that one wall or a floor between sender and receiver.
My 2.4G A/V devices don't seem to care about walls or floors, and produce a nice sharp picture when there is no interference. I have yet to find the limit to their range. They work easily from corner to corner of my fairly large house.

I have a RadioShack 2.4GHz A/V sender that I bought this year which works flawlessly (no interference at all) - EXCEPT that I must unplug my 2.4GHz Panasonic cordless phone's main base unit in order to not get interference. After talking to RadioShack's & Panasonic's tech support, I learned that there is no way around that issue because the two devices use the same frequency range. Panasonic said, however, that any 5.8GHz (or above) cordless phone should work fine with my video sender.
My workaround: I have an old cordless phone I keep by my bed and which causes no interference with my video sender. So at night when I want to use the video sender to watch the higher-end cable channels on my bedroom TV, I just unplug my Panasonic phone unit's base (I can keep the extra handset charging in its cradle base plugged in with no problem), and plug the phone's base unit back in first thing in the morning. Next cordless phone I buy will be the newer 5.8GHz model--when they go on sale.
P.S. I did have to do some experimenting at the beginning to get the video sender to work properly. I found that I must use the coax cable connector rather than the RCA-style video jack when connecting it to my OLD (but still great picture!) Sony Trinitron TV. But now it works great.

Do 2.4 GHz wireless phones interfere with the 2.4 GHz wireless video sender systems? I have 2 TVs on X-10 video senders. The work pretty well most of the time, however they go BERZERK if anyone uses the microwave in the Kitchen which is about 30 feet from where any of the senders or receivers are. Also, the TVs start making a loud crackling noise if we use any of our 2.4gh phones anywhere in the house. I tried every channel or config on the X-10 but to no avail. I contacted X-10 and they pretty much told me to change my microwave oven and phones (about $1,200) to accommodate their $49 gadget. Has anyone come up with a solution?
