Cell site power generation
First Claim
1. A system for generating power, comprising:
- means for communicatively coupling a wireless interface to a back-haul;
means for providing power from a primary power source to the means for communicatively coupling;
means for selectively generating power;
means for storing power, wherein power from the means for selectively generating power is routable to the means for storing power and to the means for communicatively coupling, and wherein power from the means for storing power is routable to the means for communicatively coupling;
multiple means for rectifying power from the means for providing power from a primary power source and from the means for selectively generating power; and
means for controlling the generation, routing, and rectification of power, including means for individually enabling and disabling each of the multiple means for rectifying power based, at least in part, on an availability status of the primary power source.

Abstract
A system, apparatus, method, and manufacture for generating backup power in a wireless communications system such as a wireless communications service base station. The system includes a communications interface, a primary power interface, a generator, rectifiers, and a battery circuit. During normal operation, the communications interface is powered from the primary power interface. During a power outage, the communications interface is powered from either the generator or the battery circuit. The generator is cycled on and off during power outages to charge the battery circuit while conserving fuel. To decrease rectification loss, rectifiers are run near full load while rectifying the generator output.

6. A method for generating power for use in a wireless telecommunications site, the method comprising:
-
communicatively coupling a wireless interface to a back-haul; providing power from a primary power source to the wireless interface; selectively generating power that differs from the primary power source, wherein the selectively generated power is routable to be stored, or is routable to the wireless interface; rectifying, via multiple power rectifiers, power from the primary power source and from the selectively generated power; and individually enabling and disabling each of the multiple power rectifiers based, at least in part, on an availability status of the primary power source. - View Dependent Claims (7, 8, 9, 10, 11)

12. A system for generating power for use in a wireless telecommunications site, the system comprising:
-
a wireless interface communicatively coupled to a back-haul; a primary power source providing power to the wireless interface; one or more other power sources that selectively generate power that differs from the primary power source, wherein the selectively generated power is routable to be stored, or is routable to the wireless interface; multiple power rectifiers that rectify power from the primary power source and from the one or more power sources; and a power controller that individually enables and disables each of the multiple power rectifiers based, at least in part, on an availability status of the primary power source. - View Dependent Claims (13, 14, 15, 16)
