The present application is directed to managing values of operating parameters used to communicate via the peripheral communication interface so as to adjust any impact on the wireless communication interface. A corresponding method includes monitoring a performance of a wireless communication via the wireless communication interface, while the wireless communication device is communicating with a coupled peripheral via the peripheral communication interface. A reference power associated with the wireless communication via the wireless communication interface falling below a first predefined threshold is detected. When the reference power which has been detected is below the first predefined threshold, a relative signal quality measurement for the wireless communication via the wireless communication interface is determined for each of a plurality of different sets of values of operating parameters associated with the peripheral communication interface. A selection is then made between each of the determined relative signal quality measurements, which respectively correspond to each of the plurality of different sets of values of operating parameters associated with the peripheral device, and the corresponding set of values of operating parameters associated with the selected determined relative signal quality measurement is applied to the peripheral communication interface.

Wireless communication device, peripheral, and method for managing values of operating parameters for a peripheral communication interface

A dual-band cellular telephone antenna. A monopole antenna is tuned to a first resonant frequency of operation. A first helical antenna is coupled to the monopole antenna and has turns surrounding the monopole antenna, where the first helical antenna is tuned to a second resonant frequency of operation. A grounded second helical antenna surrounds the first helical antenna and is formed to have an upper capacitive loading segment to tune the grounded second helical antenna at substantially the second resonant frequency of operation. The cellular telephone has a housing formed of a conductive material. A printed circuit board (PCB) has a metalized ground plane, wherein the metalized ground plane and the grounded second helical antenna are coupled to the cellular telephone housing.
