baby monitor 2 way radio image
I dont kno
I have 2.4 ghz spread spectrum cordless phone that autoselects the clearest channel everytime you use the phone and there is no way to change the channel manually. I also have a linksys 2.4 ghz wireless router. Using the cordless phone renders my wifi useless 9 times out of 10. I have tried to change the routers wireless channel (possible values are 1-11 I think) but that did not solve the problem. Does anyone know what I can do to prevent this interference?
Answer
Each device uses the same frequency band (as do garage door openers, baby monitors, Web cams, ....).
You can change frequency bands for one or the other. Use a 5Mhz phone, or a 5MHz band WiFi gear (802.11a).
Reduce the relative signal strength seen by the 802.11b/g stuff you've got. Move the phone to the other end of the house. Move the laptop (or whatever) closer, leaving the phone in the same place, ... Add an antenna (probably a corner reflector (chicken wire may be a perfectly sensible material) for the rubber ducky type of antenna design most commonly seen) to both ends of the WiFi link (you may not have to physically crack open the radios at either end, but note that this dodge increases signal strenght in one direction (and does the same to receiver sensitivity). Since both the phone handset(s) and the mobile WiFi device (a laptop, probably) is also mobile, this isn't any kind of universally adequate dodge. Find a way to reduce the phone's signal strength (probably not possible to non-techie types) unless it's possible to say, put soeme absorbing or reflecting material between the phone and the WIFi radios. An experimental bronze foil covered wall, perhaps. Ought to work well if you can keep the two radio types out of each other's effective range. May not be possible in some kinds of interior decorating environments. consult with those in charge before trying anything like this.
Another dodge ito try to arrange that the WiFi antennas are a 90 degree polarizatino difference than the phone antennas (as usually used; if you have sprawling teenagers, this may not be predictable).
Since both devices operate (or probably do) in a spread spectrum mode, each will appear to the other to be a general increase in the noise level against which they must work. Changing channels (if possible) isn't likely to be very effective. Too much noise, no radio receiver will be able to make sense of what it hears.

I want a room to room intercom for my house. What kind?
Dianaprinc
I want an intercom for my house between just two rooms - but I want it to be 2-way (so it doesn't cut out one of the talkers). I'd be happy to use a baby monitor, intercom, or phone with intercom - but I can't tell what would have 2-way speaking. My phone now is only 1-way and it doesn't work well. Does anyone have any good suggestions?
Answer
Go to Radio Shack, they have different kinds and price ranges.
