[0901.3863] Broadcasting but not receiving: density dependence considerations for SETI signals

Physicist Reginald Smith publishes what, in retrospect, seems to be an obvious answer to the Fermi Paradox, which states that if the universe is teeming with intelligent life (that is, the Drake Equation has a solution greater than 1), then why haven't we heard from them. Smith takes into account of the exponential degradation of any signal produced by a civilization and works out the minimum civilization density required for civilizations to be able to contact each other. According to his theory, under some conditions you can have a galaxy filled with intelligent civilizations but have none able to communicate with each other. Our problem may, in fact, be that we are a star on the sparsely-populated outer arm of the galaxy so outside the communication range of other civilizations.

globeandmail.com: Cellphone carriers have one year to upgrade 911 system, CRTC says

Cell phone companies have been told that by this time next year they must be able to locate callers to within a radius of between 10 and 300 meters using either GPS, triangulation, or both. Currently, Canadian cell phone companies can only locate a person to within the radius of the nearest tower, an area that can be between 4 and 20 kilometres.
