baby monitor 900mhz image

If you're on your cordless phone in your home? I've heard that its possible for neighbors with baby monitors to do this to their neighbors, and I wouldn't think this would work, unless my cordless phone acts as a monitor.
Answer
It's possible if the phone and the monitors work in the same broadcast frequency.
Most do not, however. Modern cordless phones operate in the 2.4ghz wavelength, and older ones operate in the 900mhz wavelength (the newest ones operate in the 5.2ghz wavelength, but don't worry about those).
Most baby monitors work in the 300-900mhz wavelength, so a few of them *can* pick up on older cordless phones, but those that do are few and far between... especially becase every phone and monitor is coded to only pick up a very specific frequency around their specified range... so crosstalk is less likely.

listen to other cell phone conversations with a device?

how is it possible to pick up cell phone conversations with a device, or a baby monitor.
Answer
Only analog cell phone conversations can be intercepted with a scanner. And almost no one has analog phones anymore. The newer CDMA or GSM phones use digital encoding techniques that prevent the casual listener from intercepting the conversations.
Baby monitors will NEVER overhear cell-phone conversations. Baby monitors operate at 900MHz or 2.4GHz; cell phones do NOT operate in those frequencies. However, home cordless phones DO operate in those frequencies, and these are the conversations that are often overheard by baby monitors. Newer cordless phones use the same digital encoding used by cell phones, so a new phone won't be overheard by a baby monitor.
