US 10,651,690 B2 · Wireless transmission in shared wireless medium environments

Abstract

Methods, apparatus and systems supporting coexistence of wireless transmission equipment in shared wireless medium environments. The techniques provided herein may be applied to various types of wireless transmission equipment. Under one example, a wireless power transmission system (WPTS) delivers power to wireless power receiver clients via transmission of wireless power signals using one or more frequencies and/or channels within shared wireless medium environments in which other wireless equipment is operating, such as access points and stations in wireless local area networks (WLANs). The WPTS is configured to co-exist with the operations of the other wireless equipment within the shared wireless medium environment by adapting its transmission operations to utilize frequencies or channels that do not interfere with other equipment and/or implementing co-channel and shared channels operations under which access to channels is implemented using standardized WLAN protocols such as PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.

Dependent claims

A method for delivering wireless power from a wireless power transmission system (WPTS) to one or more wireless power receiver clients in a shared wireless medium environment including one or more Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless local area networks (WLANs), comprising:

operating the WPTS to coexist with the operation of the one or more WLANs, wherein the WPTS transmits non-encoded power signals to the one or more wireless power receiver clients using at least one frequency or channel that overlaps a channel utilized by at least one of the one or more WLANs, wherein the non-encoded power signals comprise signals having a continuous wave or comprise pulsed power transmission signals.

A wireless power transmission system (WPTS) comprising:

an antenna array having a plurality of adaptively-phased radio frequency (RF) antennas;
an Institute of Electrical and Electronics Engineers (IEEE) 802.11 radio subsystem including at least one antenna;
and
control logic operatively coupled to the antenna array and the (IEEE) 802.11 radio subsystem configured to:
detect operation of one or more IEEE 802.11 wireless local area networks (WLANs) in a shared wireless medium environment including the WPTS, each of the one or more WLANs utilizing a respective channel;
and
operate the WPTS to coexist with the operation of the one or more WLANs, wherein the WPTS transmits non-encoded power signals from multiple antennas in the antenna array at a specific phase relative to each other to one or more wireless power receiver clients using at least one frequency or channel that overlaps a channel utilized by at least one of the one or more WLANs, wherein the non-encoded power signals comprise signals having a continuous wave or comprise pulsed power transmission signals.
