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 …

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 …

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 …

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 …

LoRa, more generically Low-Power Wide Area Network (LPWAN), is a promising platform to
connect Internet of Things. It enables low-cost low-power communication at a few kbps over …

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 …
