Backscatter communication (BackCom) networks enable passive/battery-free Internet-of-
Thing devices, providing reliable, massive connectivity while ensuring self-sustainability, low …

As the Internet of Things (IoT) advances by leaps and bounds, a multitude of devices are
becoming interconnected, marking the onset of an era where everything is connected. While …

The vision of embedding connectivity into billions of everyday objects runs into the reality of
existing communication technologies--there is no existing wireless technology that can …

We present the first wireless protocol that scales to hundreds of concurrent transmissions
from backscatter devices. Our key innovation is a distributed coding mechanism that works …

LoRa has emerged as a promising Low-Power Wide Area Network (LP-WAN) technology to
connect a huge number of Internet-of-Things (IoT) devices. The dense deployment and an …

This paper enables connectivity on everyday objects by transforming them into FM radio
stations. To do this, we show for the first time that ambient FM radio signals can be used as a …

We introduce the design and implementation of FreeRider, the first system that enables
backscatter communication with multiple commodity radios, such as 802.11 g/n WiFi …

There is the long-standing assumption that radio communication in the range of hundreds of
meters needs to consume mWs of power at the transmitting device. In this paper, we …

Ambient backscatter communication (AmBC) is a promising solution to energy-efficient and
spectrum-efficient Internet of Things with stringent power and cost constraints. In an AmBC …

Backscatter communication holds potential for ubiquitous and low-cost connectivity among
low-power IoT devices. To avoid interference between the carrier signal and the backscatter …
