John, I don't hold the PC to my head, but the notebook does sit in my lap. Think about that? NW

John, Re: "Not being an RF expert I really don't know. Perhaps other thread regulars can also comment. Some of these wireless devices use the 2.4ghz range, same as current high end cordless phones. From what I understand, the 'bluetooth' products will also use this range. I have also read that appliances such as microwave ovens can have some effect on at least the 'bluetooth' devices. Since these devices will not be held up to one's head it may not matter. Comments anyone???" New electronic devices, regardless of what frequencies they operate at, are strictly tested for EMC (electromagnetic compliance). They are scanned from low megahertz to about 5 times the highest frequency crystal oscillator internal to them. So, that 2.4 GHz would be tested up to 12 GHz or so, to guarantee it didn't exceed emissions specified by the FCC and similar regulatory agencies around the world. Another point is that devices intended for the home or office, like PCs and any wireless devices, are tested more stringently than devices intended for, like glass houses only, to what is called class B limits. That's because there are people holding these things to their ear, or in their lap. The only thing we need to worry about is if some newer, higher frequency EMI is, for some reason, more dangerous than frequencies that have gone before. Haven't heard of any yet. Done having children? Just a joke! Tony
