Abstract

A system and a method for activation of portable and mobile media player devices for wireless LAN services have been disclosed. In one embodiment, the system includes a server computer, a wireless transmitter to transmit a signal, and a portable device comprising a wireless receiver to receive the signal and a wireless transceiver to transition from a first state to a second state to perform content synchronization with the server computer in response to the signal, wherein the wireless transceiver consumes less power in the first state than in the second state. Other embodiments have been claimed and described.

continuously and automatically cycle between a first power mode and a second power mode at least until the signal is received by the wireless receiver; and

respond to the signal when received by the wireless receiver to cause the wireless transceiver subsystem to transition from a standby state to an active state in which the wireless transceiver subsystem uses the wireless transceiver to actively perform content synchronization with the server computer and wherein the wireless transceiver subsystem consumes less power in the standby state than in the active state; and

a synchronization budget manager which limits time during which the wireless transceiver subsystem of the portable device is in the active state as a function of an amount of power which is allowed to be expended on content synchronization, wherein the amount of power which is to be expended on content synchronization is determined based on an amount of time to recharge a battery.

2. The system of claim 1, wherein the wireless transmitter is physically coupled to the server computer.

3. The system of claim 1, wherein the server computer causes the wireless transmitter to transmit the signal periodically until the portable device responds to the signal.

4. The system of claim 1, wherein the wireless receiver includes a radio frequency (RF) receiver and the wireless transmitter includes a RF transmitter.

5. The system of claim 1, wherein the wireless receiver includes a pager network receiver.

6. The system of claim 1, wherein the wireless receiver includes a mobile cellular phone network receiver.

7. The system of claim 1, wherein the wireless transceiver includes a wireless local area network (WLAN) transceiver.

8. The system of claim 1, wherein the server computer includes a personal computer.

24. The system of claim 1, wherein the server computer further comprises a user interface configured to receive and set a plurality of predetermined synchronization times.

25. The system of claim 24, wherein the server computer is further configured to receive and store a plurality of predetermined synchronization times from the user interface.

26. The system of claim 1, wherein the wireless receiver subsystem is further configured to determine the amount of power which is allowed to be expended on content synchronization.

9. An apparatus comprising:

a wireless receiver subsystem comprising a wireless receiver and a first antenna associated with the wireless receiver;

a wireless transceiver subsystem in communication with the wireless receiver subsystem, the wireless subsystem comprising a wireless transceiver and a second antenna associated with the wireless transceiver;

wherein the wireless receiver subsystem is configured to;

continuously and automatically cycle between a first power mode and a second power mode at least until a signal is received by the wireless receiver; and

respond to the signal received by the wireless receiver to cause the wireless transceiver subsystem to transition from a standby state to an active state during which the wireless transceiver subsystem uses the wireless transceiver to perform content synchronization with a server computer, and wherein the wireless transceiver subsystem consumes less power in the standby state than in the active state, wherein the synchronization of the content is performed at a predetermined time specified by a user in response to a command from the server computer; and
