Resolved Question

Can one interpret/intercept wireless signals from a PC?

Hello! I hope this is not a repeat, but can someone please enlighten me on the magic of MHz? I noticed that things with a wireless receiver (like wireless doorbells for instance) seem to send signals at either 315MHz or 433MHz, and these signals trigger the effect of the device. I was simply wondering if a laptop computer can also receive these signals, and if so, how to do so and get an output. Thanks!

For most, no.

1. In my decades of work in wireless things (remote controls, car alarm remotes, data links and so on) not one PC had the gear to capture or send this signal.

2. That doesn't mean I didn't craft a device to automate testing from a PC but you would be "the engineer" to make and program this. There are no generic ready to use products here.

Well that sucks.

So I would need a arduino or a separate receiver to make it work. That's sad, but I had to know. Thanks, mate.

Sounds like.

You are looking for a hack. I'd be careful here as no help will be given.

Answer
frequency

You'd need a device that could connect to computer and intercept at exactly that frequency. Consider the lowest frequency for most computer wireless devices is 2.4 Ghz, not down in the Mhz range. Interestingly, microwave ovens operate in the same 2.4 Ghz range. Just think of what one could do with a "fixed" microwave oven aimed at a neighbor's wifi reception, LOL.

No, unless...

...you are a fully trained radio engineer, in which case, you could design and build a suitable interface unit to pick up the transmission, sort out the bit you want and convert it to some format the PC understands. Hint: this is not easy, even then - life's too short!

Actually, most people with these so called smart devices would be verry happy to know it's too hard to be practical.
