The invention relates to a silver low-E coating for glass which is temperable and can be applied by means of sputter processes onto the glass. A power output is operatively connected to the gear system for deriving power therefrom. The modular turret cage has a top end and a bottom end. A third example method includes receiving a plurality of interference indicating signals from different base stations and determining whether to adjust a maximum transmit power threshold based on the plurality of interference indicating signals, the maximum transmit power threshold indicating the maximum permitted transmission power level below which transmissions are constrained.
