Have you noticed your wireless internet connection dropping without
warning ? Your cordless phone might be to blame. Wireless routers
utilize the 2.4 gigahertz frequency band, and so do most cordless
phones. Bluetooth devices, Xbox 360 controllers, Playstation 3
controllers, baby monitors, and microwave ovens can also interfere
with wireless signals. Cellular phones do not contribute to
interference with Wi-Fi because they operate on very different
frequencies.

The Federal Communications Commission has divided the airwave spectrum
into bands that are reserved for certain uses. The crowded 2.4 GHz
band is divided into 14 channels. Some devices randomly select a
channel to operate on each time they are powered up, while others
rotate channels during each session of use. When a device is operating
on the same channel as a phone, the user hears severe static.

The same garbling that causes static is deadly wireless internet.
Interference is not limited to situations where devices are operating
on the same channel. If devices are operating on adjacent frequencies,
there can still be interference.

Luckily, there is a short term solution to the problem. A new
generation of cordless phones operates on the 5.8 GHz band. These
phones also allow users to roam farther from the base. 5.8 GHz phones
have come down quite a bit in price, and are now available from major
retailers starting at $35. By utilizing a 5.8 GHz phone, you will be
able to unclutter the 2.4 GHz band in your home.
