Won't my Wirefree Home interfere with my neighbor's?
It could, and vice-versa, but it's easy to fix most of the problems. The systems are digital, with hundreds of "codes", so usually it's just a matter choosing non-identical codes for neighboring
homes. The systems are all designed for short-range operation (Yes, for REALLY big homes there are amplifiers and repeaters so the signals go from one end to the other. Don't worry!), so they shouldn't
interfere anyway. And finally, we can install "blocking filters" to stop your home's signals from leaving it or your neighbor's signals from getting in.
Don't wired systems perform better than wirefree systems?
There are some things a wired system does very well. Your home telephone wires are one. They usually carry conversations clearly, without interference, in full privacy, and standard telephones
can be purchased almost anywhere and for very little money, and because the phone line also powers your telephone they continue working even when power fails at your house. Wirefree extension phones occasionally
pick up interference from other electrical devices, they transmit your conversations over radio waves anyone can receive, and they stop working when you have a power failure because the base units plug
into your 110 volt power outlets. Technology has reduced most of these problems (higher frequencies for clearer signals, digital encoding of the transmissions so they are private, caller ID displays right
on the wirefree handsets), but nobody would ever argue your entire phone system should be wirefree. Still, there are compelling reasons for expanding a basic wired home telephone system without wires.
First, there is cost. Two hours of the phone company's labor in putting in new telephone wires bills out at $500. There are multi-handset wirefree telephone sets that let you expand your home telephone
system in under 5 minutes, without drilling any holes in walls, stapling wires all over the outside of your house, or dealing with scheduling and rescheduling of visits by phone company installers. Second,
there is the freedom a wirefree system offers. Instead of sitting by the (wired) telephone waiting for an important call, you can carry the wirefree handset and take it with you as you mow the lawn, or
go out to your pool.
Wiring home entertainment systems between rooms provides very clear, reliable operation. But wirefree systems let you later add additional rooms with only the minor cost of an additional receiver.
Today's higher frequencies allow wirefree systems to match wired clarity, and you often get through-the-wall use of your remote control as a "free" additional feature that is NOT part of a wired system.
As television moves digital to HDTV, wirefree systems will be there to allow you to upgrade without concern that "the best cable available" at the time you wired your house will still be "not good enough"
for the very high bandwidths needed by HDTV signals.
