An RF power amplifier operates over the range of supply voltages provided by a DCDC converter whether the range of voltages is intentional or unintentional. The RAN may initiate a paging process to page the WCD, and the paging process may comprise the RAN transmitting to the WCD a defined sequence of page attempts until the RAN receives a page response from the WCD or the RAN has transmitted a final page attempt of the sequence. The reflective mirror element does not exhibit substantial spectral selectivity in its reflectance of visible light incident upon its front side. Also, identified are any annotations, bookmarks, or the like that the identified trusted sources have associated with any shared content. Additional features include providing generalized or customized identifying data to cooperating content providers. The laser source preferably comprises an optical fiber Raman laser.
