Electro-SMOG is the electromagnetic energy that is emitted by common gadgets in our home such as our televisions, cordless phones, microwaves and digital baby monitors. Studies have been made over the years claiming that too much exposure to electro-SMOG can result to health problems affecting the nervous system of the body. So for those who are experiencing this kind of problem, here are a few tips on how to minimize interference with your wireless baby monitor. 1) Signals coming from wireless devices usually clash with other signals from other wireless devices running on the same frequency. When this clashing occurs, wireless interference occurs. By simply positioning one radio transmitter in each room, you can listen to the sounds coming from your baby's room even if you're busy with house chores or other stuff. Then again, this added capability comes with a number of drawbacks. The baby monitors could interfere with each other. For that reason, you need to make sure that they are set in different frequency bands; otherwise, you will only be able to hear irritating electronic screeches. Opt for a wireless phone that utilizes the 900MHz, 1.9GHz or 5.8GHz band. Since these channels are not as commonly utilized as the 2.4GHz frequency band, they're less prone to interference. If you have a preference for multiple-handset-capable wireless phones with a handset-conferencing option, pick one that makes use of only the 1.9GHz or 5.8GHz channel.
