(PhysOrg.com) -- When consumers use their cell phones, reception can depend on the strength of the signals coming to and from wireless base stations. Those base stations in turn depend on high-power amplifiers to extend their range - amplifiers that typically consume ten times more power than they generate, for a 10 percent efficiency rate.
