Wireless networking communication methods, systems, and devices operable using harvested power
First Claim
1. A device comprising:
- an antenna, the antenna configured to receive wireless network communication signals provided by another device;
a channel modulator configured to modulate a channel associated with the wireless communication signals, wherein the channel modulator is configured to modulate the channel by adjusting an impedance of the antenna in accordance with transmit data for transmission to the another device, wherein a first time during which the channel is modulated for each bit of transmit data is greater than a second time required for transmission of a plurality of packets of the wireless network communication signals.

Abstract
Example devices described herein include endpoint devices which may communicate with an access point device by modulating a channel associated with the wireless communication to encode transmit data. The channel modulation may be performed by utilizing a switch to control an impedance of an antenna at the endpoint device to either reflect or absorb wireless network communication signals received by the endpoint device. The access point device may extract the transmit data by decoding changes in the channel caused, at least in part, by the modulation. Access point devices may transmit a pattern of packets—the presence or absence of which may correspond with transmit data. Endpoint devices may decode this data by using an energy detector to differentiate between the presence or absence of a packet.

12. A method of wireless networking communication, the method comprising:
-
receiving, at an endpoint device, wireless networking communication signals provided by an access point device; decoding, at the endpoint device, a query from the access point device, wherein the query is transmitted using a presence or absence of a packet to indicate a bit; responding to the query by transmitting data to the access point device, at least in part by modulating a channel associated with the wireless networking communication signals, wherein a first time during which the channel is modulated for each bit of data is greater than a second time required for transmission of a plurality of packets of the wireless networking communication signals. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
