Reducing cell phone radiation exposure
Technology Review - I love that magazine. It's published by MIT and I just got my copy today because I'm on the MIT alumni mailing list. On the Tech Review blog, there's a post titled, "How to Reduce Cell-Phone Radiation Exposure." The author writes that a new network architecture could dramatically reduce the radiation exposure from cell phones. Wouldn't it be great if we could reduce radiation and boost battery life? What if we could enhance existing networks by adding large numbers of base stations that only receive signals and are connected up to the rest of the network via a landline or a line-of-sight microwave link? There's an Israeli startup called Greenair Wireless and that's what they're trying to do. What's the big deal about radiation exposure? Chronic exposure to radiation may be linked to a higher risk of cancer. So do cell phones cause brain cancer? It's still a controversial topic and I don't think we'll have a clear answer for a while. In the meanwhile, anything that we can do to reduce that exposure would be warmly welcomed by all of us who are now so dependent on mobile phones and smartphones.
