said by Naterator :Yes, but only a short burst of static interference. As the sun does not expose you to the same type of radiation and radio waves. Hence your cell phone may be drowned out. Just like you can boil water with radio waves, there are different types and different amounts. 1 short burst, a lifetime of exposure. Just saying...
The sun emits radiation of every frequency (from sub-Radio to Gamma+), at high intensities. Why do you think Wi-Fi and cell towers can only cover a specific area and not forever?
