Benefits of technology
This approach significantly extends battery life by optimizing power usage, allowing devices to operate longer between charges while enabling compliance with regulations that restrict radio frequency emissions, such as in aircraft environments, and supporting multimedia data transfer demands.
Problems solved by technology
However, IEEE 802.11 networks lack high data rate and Quality of Service (QOS) features to support multimedia communications.
However, Bluetooth communication links cannot support the data transfer requirements of portable consumer electronics devices that transmit and receive multimedia data, e.g., high quality video applications, audio applications, and multi-megabyte file transfers for music and image files.
The current designs and proposals, however, do not provide any suggestions for maximizing the amount of power savings and do not provide for power saving modes and periods that maximally extend battery life.

Embodiment Construction
[0033]FIG. 1 is a schematic block diagram illustrating a communication system 10 that includes a plurality of base stations or access points 12-16, a plurality of wireless communication devices 18-32 and a network hardware component 34. The wireless communication devices 18-32 may be laptop host computers 18 and 26, personal digital assistant hosts 20 and 30, personal computer hosts 24 and 32 and / or cellular telephone hosts 22 and 28. The details of the wireless communication devices will be described in greater detail with reference to FIG. 2.
[0034]The base stations or access points 12-16 are operably coupled to the network hardware 34 via local area network connections 36, 38 and 40. The network hardware 34, which may be a router, switch, bridge, modem, system controller, etc., provides a wide area network connection 42 for the communication system 10. Each of the base stations or access points 12-16 has an associated antenna or antenna array to communicate with the wireless commu...

A hand held radio host includes circuitry for selectively providing power to radiating transceiver elements and non-radiating application elements according to a plurality of power modes of operation to achieve desired effects and in a way that saves power and extends battery life. In one embodiment of the invention, the hand held host operates in one of three modes. In a full power mode, any selected application element as well as all transceiver elements are powered on at the same time. Thus, for example, a cell phone module, a wireless personal access network module, a wireless local area network module and one of a pager / short message service message module may all be powered on at the same time to receive corresponding messages, calls, data sessions, etc. At the same time that all of the transceiver elements are powered on, any selected application element receives power. Thus, application elements such as address books, calendar functions, games, word processors, and similar other application elements may receive power when selected.
