Abstract: A wireless terminal with virtual memory for use in a wireless communications network and a method of using such a wireless terminal is provided. The wireless terminal comprises a transceiver for receiving and transmitting information over an active wireless link with the communications network, virtual memory to store information received over the wireless link with the communications network and display means to view the information stored in the virtual memory without requiring the active wireless link with the communications network. The method of using the wireless terminal with virtual memory comprises the steps of downloading data from a server over an active wireless link to the virtual memory of the wireless terminal and accessing the data stored in the virtual memory at the wireless terminal without requiring the active wireless link.

Abstract: The invention relates to methods and apparatus for synchronizing a local data clock with timing information from received data, during a fraction of a frame period. The apparatus includes a transition detect unit, a digital phase comparator, a phase regulator, and a control unit, for detecting the bit transitions of received data, determining the phase difference between timing information and a local data clock, advancing or retarding the local data clock, and enabling and disabling the synchronization in accordance with a predetermined rate.
