Are you using wireless technology? How old is it? Might be time to upgrade your
equipment. 10 meters is about 33 feet, but remember the technology available to the
government could potentially reach beyond that. Then there are other things people forget
such as wireless monitors which broadcast your screen to a receiver that can be picked up.
Just think about the old antennas people used to have on top of their homes, and how far
away those could pick up signals from TV stations, if you had one of those pointed at you
in a van across the street, there is no doubt they could be eavesdropping on your activities
inside.
One researcher was able to use a wireless signal sent by a smart meter from up to 300
meters away (900 feet) to find out which house it was coming from and what the current
power consumption was in plain text. She was then able to use this information to
determine when people were and were not home based on average spikes in consumption
since the meters pulse every 30 seconds.
“The data sent was in plain text and carried the identification number of the meter
and its reading. The name of the home owner or the address aren’t included, but
anyone motivated enough could quickly figure out the source.
“The meter ID was printed on the front of the meter we looked at, so theoretically
you could read the ID [off a target meter] and try to sniff packets,” Xu said.
In her tests, Xu found she was able to pull packets out of the air from target meters
between once every 2 to 10 minutes. That’s fast enough to be able to work out the
average power consumption of a house and notice start to deduce when someone is
at home.”

Things like automatic timers that flip switches might be worth investing in to always make
it look like someone is home until security researchers start looking into ways to avoid the
wide open door we are giving to anyone who wants to find data about us.
What can you do about these types of eavesdropping? Not a whole lot unless you want to
start turning into a tin-foil hat type of person. There are some fun things you can do if you
want to go crazy with it though as recommended by the following site.

There are lots of other things on there as well like drapes, curtains, garments, fabrics and
so forth which disrupt the transmission of these signals. It is completely up to you what
you want to do, I am just giving you the options and the education so you can make an
educated decision of how far you want to go to protect your privacy.
