This is a short video about Amazon Kindle 4. I got it several days ago. Its very very nice device. The most important thing for me is that it has option of disabling Wi-Fi. Here I have my gadget that can measure radiation
that comes from such radiation emitting devices. And kindle is one of them if you turn this option ON. So, let’s do it and see how much radiation it gives. I already registered my kindle, when I turn wireless ON it does synchronisation or some other process.. And after that it stops using wireless connection. Now lets do something like going into menu, we will choose…oh, even without any important operations it had some strange pulse. OK. Probably after entering each menue it has this strange pulse? Lets go back and to the end of this menue just to see if we are right.. Oh, nothing happened 🙂 OK As I said before this device is already registered. What we can do is to view all the Wi-Fi networks that we have here. Here we have option of rescan of list and we wil ldo it several times
just to see how kindle tries to find networks around me. This operation usually requires a lot of radiation to be emmited. But what we see here that
despite of very short distance between my antenna and kindle the level does not go too high. like on most smartphones. So, radiation level is really low. I can rate it as low one. Lets do several rescans. One rescan… Two rescan. Let’s change position of the kindle… Three rescan.. very low.. Now let’s do some browsing. We go main Menue ->Experimental.. Here we have browser.. WE find bookmarks here.. And we go to see something big, for example yahoo.com page. Oh.. this is realy low level of Wi-Fi signal here! Very nice! OK. Usually all devices like smartphones (Samgung Galaxy, iPhone4 and other) emit level of Wi-Fi that exceeds 2000 here on this scale. And units that we have here are micro watts per square meter (uW/m2). That is pretty low. But for me who don’t like microwave radiation, Even level of 10 is not that good. And now we see that when we even look on static page, without clicking anything, kindle still connects maybe to download some advertisments.. Anyway, I suppose you not to use wireless option in kindle. Just turn it off. Only when you really need to connect via wireless connection of kindle turn it ON, use it and turn it OFF. OK, I hope this video is not too bad.
Sorry for my bad English. I tried to do my best.
