Patent ID: 8125959

Claim:
A handheld computing unit comprises: a plurality of physical layer (PHY) units, wherein a PHY unit of the plurality of PHY units is operably coupled to, when the handheld computing unit in a femtocell access point (AP) mode: convert an upstream user equipment (UE) radio frequency (RF) signal into an upstream PHY signal in accordance with a femtocell protocol; and convert a downstream PHY signal into a downstream UE RF signal in accordance with the femtocell protocol; a local wireless interface (LWI) operably coupled to: convert LWI upstream data into an LWI upstream RF signal in accordance with a local wireless interface protocol; and convert of an LWI downstream RF signal into LWI downstream data in accordance with the local wireless interface protocol; a processing module operably coupled to, when the handheld computing unit is the femtocell AP mode: perform one or more femtocell AP functions to facilitate conversion of the LWI downstream data into one or more downstream PHY signals and conversion of one or more upstream PHY signals into the LWI upstream data, wherein the one or more downstream PHY signals include the downstream PHY signal and the one or more upstream PHY signals include the upstream PHY signal; determine energy demand of the handheld computing unit; determine whether the energy demand compares unfavorably to energy performance criteria; and when the energy demand compares unfavorably to the energy performance criteria, execute an energy adjustment algorithm.
