2nd SWITCH IoT Day

Thursday, 22nd of November 2018 at SWITCH

Low powered wide area networking technologies offers long ranges, small bandwidth, and enables new services. There are many solutions, but LoRaWAN is arguably the most adopted one. It promises ubiquitous connectivity in outdoors IoT applications, while keeping network structure and their management simple. Nevertheless, "The Internet of things" got a lot of attention at network operators and solution providers.

The SWITCH IoT Day is organised as a workshop. It provides exchange of knowledge and expertise from the “The Things Network” with focus on the TTN-architecture v3, from community use cases, application development, research activities, and results from the Industry.

In addition to the TTNv3 we invite attendees to participate in Use Case Sessions, Lightning talks and pannel discussions.

Full Sessions - Abstracts: 

Session 1: Decentlab, founded in 2008 and a spin off from Empa started by monitoring structural health of built infrastructure and successively expanded into other areas such as environmental monitoring and smart-city projects. The presentation will give an overview of our monitoring activities in research projects over the last 10 years. It highlights countrywide deployments and long term research initiatives. The audience will hear about most critical phases, pitfalls and our experiences in the field.

Session 2: At Tamedia, getting the right amount of 20 Minuten newspapers into the hands of eager readers is quite important. Following that thought, Tamedia developed a device that measures the height of newspaper stacks with a time-of-flight laser. The collected data is then sent through LoRaWAN, processed and displayed in a consumer frontend. In this short talk, Fabian Mettler and Mathias Vettiger will speak about their experience collecting and processing data from the urban wilderness (and tell some stories about vandalism and a newspaper box with a lowerable bottom).

Session 3: Ocalization has been a revolution in many fields with the arrival of GPS in the 1990s. Since then knowing one’s position has been taken for granted. For places and scenarios where GPS could not be used both indoor and outdoor, solutions were not obvious. The arrival of LoRa contributed to partially address the outdoor issue mainly in terms. For the indoor, if lots of solutions are advertised, none are reaching the level of de facto standard. This talk will present difficulties facing the actors of localization and implemented solutions

Lightning talks - Abstracts: 

Slot1: The Things Network (TTN) provides an open network infrastructure for LoRaWAN-connected sensor devices. But how can the collected data be passed on, e.g. for storage or analysis? This talk will explain the basics of integrating custom and 3rd-party Web apps with the TTN backend server. The presented mechanisms include MQTT, a messaging protocol, and HTTP Webhook requests, sent by the backend. We will also take a look at data formats and systems architecture trade-offs, to make dependencies more explicit and reduce lock-in when designing IoT solutions.

Slot2: IoT is a big opportunity to environmental research. For example temporal and spatial resolved concentration measurements of pollutants combined with weather stations have the potential to detect unknown emission sources and trace the transport of pollutants. While there are more and more small, low energy sensors available at affordable prices, signal filtering and real time transport of the data to the computer of the researcher remains to be a challenge and is in many cases the most expensive part of the sensor-network.

Slot3: The number of connected things and devices already exceeds the population of Switzerland today. New network technologies are needed so that the population and the economy can benefit from the new opportunities. LoRaWAN allows already today an easy entry into the world of IoT. Future technologies such as 5G will open up completely new fields of application.

Slot4: 

Slot5: Blossoming visions foresee an ubiquitous availability of data in urban environments enabled through emerging sensors and novel transmission technologies. In our talk, we share experiences from two years of operation of a low-power wireless sensor network (LPWSN) with 50+ sensor nodes distributed in a 3 x 3km urban area, with 70% of the nodes positioned underground (sewer network). In essence we i) illustrate the scalability of a LPWSNs, ii) reveal telemetry limitations of the LoRaWAN standard, iii) suggest techniques to master these constraints, and iv) discuss future challenges associated with LPWAN techniques for (underground) infrastructure monitoring.

Slot6: 

Slot7: The optimization of public spaces is integral for the development of smart cities. The Internet of Things (IoT) offers an approach to evidence-based design that can guide this optimization process by capturing and quantifying human behavior. Here, we propose a dense sensor network that is capable of measuring environmental conditions and human activity in a public space. We present our prototype of a LoRaWAN-based sensor network with more than 1300 nodes in the Rietberg museum, Zürich. This prototype shows how human activity can be tracked at a fine scale by passively sensing the surrounding environment rather than actively monitoring visitors.

Slot8: The LoRaWAN infrastructure and its ecosystem proved to be a serious competitor for traditional low bandwidth, low power wireless (internet) access. Most common use cases focus on sensors of all kinds, mostly invisible to the end user. We are going to show some examples of LoRaWAN end nodes with direct user interaction.
