How wireless keyboards work

I know this is a hardware forum, but I really want to purchase this new Sony all in one with wireless keyboard and mouse.

My wi-fi works perfect in my house.......but all my cordless phones have major interference.....and I am not sure if the keyboards will work.

Is there a chance they are running on same frequency as the cordless phones? Is there a way to adjust frequency in the software.

Does this apply to any wireless keyboard and mouse situation, except bluetooth? What is the difference between optical and just wireless.

I bought optical mouse and things did not work so well.

Help!!!!

Keyboards use a different technology (usually IR), and will not affect Wi-Fi, Cell Phones or Cordless phones. You will be just fine. No frequency adjustments are needed.

 

If you replace all your cordless phones with ones that operate at 5.8ghz, you'll no longer have interference problems. The keyboard probably uses RF or Bluetooth technology, so it shouldn't be a problem.

 

No, wireless keyboards RARELY use IR for communication. IR requires a line-of-sight connection. RF means Radio Frequency, and they're often operating in the 20-50MHz (notice the M) band or so. Nothing that it'll interfere with.

 

This seems like it might be an RF keyboard. (The 20-50MHz, Pitabred mentioned). From the link provided, it seems that there is an RF receiver that is hooked up to the PC and most likely acts as a receiver for the Remote control, Keyboard, and mouse.

The range on RF equipment isn't the best, especially if there is some interference, but is usually fine for a situation where you are only sitting a meter or 2 away from the receiver, plus the receiver is chorded so you can place it closer to the peripherals if you get too much interference.
