Wireless sensing has evolved since the discovery of radio wave echo detection and radar in 1886. Analyzing electromagnetic reflections from objects opened the way for a wide range of applications spanning from locating long-range targets for navigation and military to monitoring wind and precipitation for weather-forecasting to velocity...

Reproducibility is key in designing wireless systems and evaluating their performance. Trying to reproduce wireless experimentsallowed us to identify some pitfalls and possible ways to simplify the complex task of avoiding them. In this paper, we expose a fewconsiderations that we learned are instrumental for ensuring the reproducibility of...

Evaluating and comparing performance of wireless systems, like for any other scientific area, requires the ability to reproduce experimental results. In this paper, we describe the specific issues that we encountered when focusing on reproducing the experiments described in a paper related to wireless systems. We selected the OpenRF paper...

In this paper, we present R2lab, an open, electromagnetically insulated research testbed dedicated to wireless networking. We describe the hardware capabilities currently available in terms of Software Defined Radio, and the software suite made available to deploy experiments. Taking as a pretext a dummy experiment, we show how it all fits into...

Experimentation is an essential step for realistic evaluation of wireless network protocols. The evaluation methodology entails controllable environment conditions and a rigorous and efficient experiment control and orchestration for a variety of scenarios. Existing experiment control tools such as OMF often lack in efficiency in terms of...

We describe a demonstration run on R2lab, an anechoic chamber located at Inria Sophia Antipolis, France. e demonstration consists in deploying a standalone 5G network in less than 5 minutes. All the network components (base station, subscriber management, serving and packet gateways, network traac analyzers) were run automatically using the...

This papers introduces Snipe, a novel system offering joint localization and range extensions for LPWANs. Although LPWAN systems such as Long Range (LoRa) are designed to achieve high communication range with low energy consumption, they suffer from fading in obstructed environments with dense multipath components, and their localization system...

Smartphones are today affordable devices, capable of embedding a large variety of sensors such as magnetometers or orientation sensors, but also the hardware needed to connect them to most wireless communication technologies such as Wi-Fi, Bluetooth, or cellular networks. Therefore, they are handy devices able to perform Received Signal...

Smartphones are today relatively cheap devices that embed a large variety of sensors such as magnetometers or orientation sensors, but also the hardware to connect to most wireless communication technologies such as Wi-Fi, Bluetooth, or cellular networks. For this reason, companies, such as OpenSignal or Tutela use smartphones to make...

Reproducibility of artifacts is a cornerstone of most scientific publications. To improve the current state and strengthen ongoing community efforts towards reproducibility by design, we conducted a survey among the papers published at leading ACM computer networking conferences in 2017: CoNEXT, ICN, IMC, and SIGCOMM. The...

With MIMO, Wi-Fi led the way to the adoption of antenna array signal processing techniques for fine-grained localization using commodity hardware. These techniques, previously exclusive to specific domains of applications, will spur interest to reach beyond localization, and now allow to consider estimating the device's orientation in space,...
