wireless devices as part of your computer solution

Wireless devices approximately use the same frequency ~2.4Ghz. Too many wireless devices and a cordless phone that is in the same location which occupies 2.4Ghz may interfere with other wireless devices.

"Newer" frequency wireless phones, set to operate at DECT 6.0 Ghz, may cause less interference.

In the United States, the following channels can be used. Remember the original cordless phones that used to "auto-select" channels? Well, this table basically shows the channels. As stated, in the United States only channels up through channel 11 are able to be used.

Some devices, such as microwave ovens and speakers may also cause interference to wireless devices, or impede performance.

So, with all of this in mind, use caution because the following devices are some of the list that are available as wireless.

• Video Monitors
• Routers
• Firewalls
• Printers
• Mouse (mice)
• Keyboards
• cordless phones

We have no data at this time that either proves or disproves whether wireless/mobile phones or other devices (BlackBerry, iPhone, etc) by the Wireless telecommunications companies (Verizon, ATT, Sprint, T-Mobile) impede performance or interfere with other devices. We do know that there is a debate of whether wireless telecommunications interfere with instruments such as avionics.
