Abstract
A handheld computing unit includes a processing module and a plurality of PHY units. The processing module determines whether a femtocell access point (AP) mode is active. When the femtocell AP mode is active, the processing module determines whether at least one other handheld computing unit is supporting femtocell AP operations. When another handheld computing unit is not supporting the femtocell AP operations, the processing module enables the femtocell AP operations. A PHY unit of the plurality of PHY units converts a downstream PHY signal into a downstream radio frequency (RF) signal and converts an upstream RF signal into an upstream PHY signal.
