WIRELESS ENERGY TRANSMISSION

摘要

An energy transmitting device (e.g., access point) can transmit an energy signal to a wireless device. The wireless device can obtain energy from the energy signal. The energy signal may be transmitted via an unused frequency sub-range of a frequency range associated with a communication signal. In one embodiment, the energy signal may occupy a frequency sub-range in unused frequencies of an orthogonal frequency division multiplexed (OFDM) signal transmission. The energy signal may be transmitted in a manner that coexists without interfering with traditional communication signals. Various control/configuration settings may be used to enable or disable the energy signal, for example, based on capability of a wireless device to harvest energy from the energy signal or in accordance with a schedule.
