Abstract
A method and an apparatus for enabling battery power saving in an associated device is disclosed. Said battery saving is enabled by receiving electromagnetic energy carried by a wireless signal, obtaining operating power from the received electromagnetic energy, receiving a data unit over a wireless link, storing the data unit in a memory, and providing the data unit from the memory in response to a memory read request received via an input/output controller.
Claims28
A method comprising:
- receiving via a first wireless link electromagnetic energy carried by a wireless signal;
- obtaining operating power from the received electromagnetic energy;
- receiving a data unit over a second wireless link that is separate from the first wireless link, wherein the second wireless link is an impulse radio link;
- storing the data unit in a memory;
- and
- providing the data unit from the memory in response to a memory read request received via an input/output controller.

An apparatus comprising:
- a power unit configured to receive via a first wireless link electromagnetic energy carried by a wireless signal and to obtain operating power for the apparatus from the received electromagnetic energy;
- a communication unit configured to operate a communication connection over a second wireless link that is separate from the first wireless link, wherein the second wireless link is an impulse radio link;
- an input/output controller;
- a memory;
- and
- a processor configured to:
- receive a data unit from a peer apparatus via the second wireless link;
- store the data unit in the memory;
- and to
- provide the data unit from memory through the input/output controller in response to a memory read request received through the input/output controller.

A computer program embodied in a computer readable memory medium configured to cause an apparatus on executing the program to perform:
- receiving via a first wireless link electromagnetic energy carried by a wireless signal;
- obtaining operating power from the received electromagnetic energy;
- receiving a data unit over a second wireless link that is separate from the first wireless link, wherein the second wireless link is an impulse radio link;
- storing the data unit in a memory;
- and
- providing the data unit from the memory in response to a memory read request received via an input/output controller.
