In recent years, it clearly emerged an increasing importance of experimental validation of innovative wireless solutions and applications, due to the increasing complexity of the wireless ecosystem. The WiNTECH workshop explicitly deals with methodological and technical issues that have to be faced for defining, running, controlling and benchmarking experiments on wireless solutions. The workshop, that this year reach the 13th edition, has a consolidated tradition for bringing together an important number of researchers and industry players working in different aspects of experimental wireless communications. The workshop will serve as a forum for sharing experiences and results with real testbeds, experimental evaluation, prototyping and empirical characterization of wireless technologies.
The workshop will facilitate discussions on unresolved issues in the field, such as new laboratory methodologies, key real-life limitations of current and novel wireless technologies that have emerged over the past few years (including mmWave, underwater, 5G, IoT, wearables, and SDN), as well as key challenges facing the wireless networking of the future. WiNTECH has an inherent experimental nature and thus will include a relatively large demo session where real testbeds, deployments and prototypes can be shown and discussed. Moreover, the research community will be challenged to show us their latest, breakthrough, chair-rocking and mind-blowing innovations, through the demonstration competition.
All the regular papers will be considered for the Best Paper Award.

Enabling OFDMA in Wireless Backscatter
Associate Professor, Shanghai Jiao Tong University
Wireless backscatter communication can provide ultra-low power backhaul to Internet-of-Things (IoT) devices, which usually have very limited energy budgets. With the proliferation of IoT widgets into human activities, an important design goal for the backhaul is to connect as many devices as possible, which are featured by short bursts of data. The crux to achieve this goal is to enhance concurrency of the wireless backscatter network, so that many concurrent transmissions can be supported. Orthogonal frequency division multiple access (OFDMA) is a multiple access mechanism based on orthogonal frequency division multiplexing (OFDM), which is a multi-carrier modulation mechanism widely used in modern wireless systems including 802.11 a/g/n/ac, 4G and 5G.
This talk focuses on how to enable OFDMA in the wireless backscatter network, which not only maintains the advantage of ultra-low power consumption but also improve the system concurrency. The major challenge for enabling OFDMA in wireless backscatter is to achieve the strict synchronization in both time and frequency domain. In fact, the synchronization is critical for all the OFDMA systems; however, in the OFDMA backscatter network, the signal at the receiver side is reflected from backscattering devices (tags), thus introduce more opportunities for offsets in both time and frequency domain, which incurs new challenges in the system design.
This talk presents the major challenges in realizing OFDMA backscatter network, and provide our solutions to deal with those problems. The design for excitation signal transmitter, tag and receiver will be explained. The phenomena we observed in realizing the system will be illustrated. Moreover, the new issues discovered in existing OFDMA backscatter is to be revealed, and the preliminary result for the future work is also to be presented.

In recent years, we observed an increased importance of experimental and empirical work on wireless research. In this talk we will thus describe industrial testbeds and operational environments and the research that can be done on them. Specifically, we will focus on Telefonica and Samsung research providing examples on operational cellular networks, mobile edge computing testbeds, and IoT labs. We will talk about the applications we tackled in this testbeds, analytics and machine learning algorithms we developed and measurements studies. Finally, we will overview 5G testbeds as well as, other open mobile testbeds.

ACM WiNTECH has advanced to its 13th anniversary as one consolidated tradition for bringing together an important number of researchers and industry players working in different aspects of experimental wireless communications. The workshop will continue to serve as a forum for sharing new ideas and experiences gathered across all experimental aspects of wireless networks and systems, such as the methodological and technical issues that have to be faced for defining, running, controlling and benchmarking experiments on wireless solutions. The workshop will also facilitate discussions of key unresolved challenges and emerging problems in the field, such as new laboratory methodologies, key real-life limitations of current and novel wireless technologies that have emerged over the past few years (including mmWave, 5G, IoT, VLC, wearables, mobile CHI and SDN), as well as key challenges facing the wireless networking of the future.
We are seeking original, previously unpublished papers empirically addressing key issues and challenges in wireless networking. All submissions will be judged by their technical merit and relevance to the workshop, based on a thorough review process by the Technical Program Committee.
Topics of interest include, but are not limited to:

WiNTECH continues its established tradition of hosting an interactive demo and poster session, and welcomes proposals for demonstrations of novel work in wireless network testbeds, measurement platforms and results, and innovative prototypes. The areas of interest overlap those listed in the workshop call for papers. The innovations showcased can be at any layer of the protocol stack, from physical to application. However, we particularly encourage demonstrations and posters that span over multiple layers and wireless networking must be their key topic.
The demos must be presented live at the workshop venue, i.e., a presentation of a powerpoint, video, etc. only is not allowed. The posters may describe work in progress, while the session will offer an excellent opportunity to receive feedback and discuss early research. We emphasize that the poster/demo session is not a forum to display commercial products.
Each submission must be a single PDF file no longer than two pages in length (including figures, tables, and references), using two-column format, 10-point size or greater and in PDF format following the same formatting guidelines as the main conference. Papers must include the author name and affiliation. All poster titles should begin with the keyword "Poster:" and all demo titles should start with "Demo:". The demo should list the demo requirements at the workshop venue if they are more than a table. All remaining submission guidelines are the same as that of the main conference. Papers must include the author name and affiliation. All the submissions will be sent to email@example.com
