IoT and LoRa
Update 23-03-2017
After the warm welcome by KIVI Telecommunications vice-chairman Huib Ekkelenkamp, Anne van Otterloo provided Introduction on IoT.
We were then introduced to LoRA by IoT pioneers Dirk Gooris and Pieter van Niewaal with completely renewed radio technology.
They clearly explained how they managed to improve the signal-to-noise ratio and make it possible to transmit data over several kilometres with a very low transmission power.
This was followed by a live demonstration of the operation of the LoRA using their own equipment.
The presentation by Jasper from Kuin KPN showed how KPN has rolled out LoRa nationwide and is able to provide a service for reliable data connection for IoT.

Rotterdam-based RDM Makerspace has launched a crowdfunding campaign via Kickstarter for a LoRa development board.
The kit can be used to build rapid prototypes for Internet of Things (IoT) applications. The 'Long Range Wide Area Network' (LoRaWan, or LoRa for short) is used for IoT applications because LoRa is very suitable for sending small amounts of data over long distances (10 to 15 kilometres).
The development board, christened 'Marvin' by RDM Makerspace, should greatly facilitate the development of IoT applications.
Marvin is based on an Arduino Leonardo and is compatible with Grove sensors.
The entire Marvin board is essentially a large USB stick (2.4 mm thick PCB) and so can be plugged into laptops (or powerbanks) without cables.
Wireless communication, as mentioned, is via the LoRa standard. This is because RDM Makerspace sees LoRa as an important catalyst for the development of the Internet of Things. The Microchip RN2483 acts as the LoRa module and can be used anywhere in the Netherlands and in other countries rolling out LoRa networks.
Programming knowledge not required
For the hardcore programmer, Marvin offers a (open-source) platform full of possibilities. Yet you don't need to be able to write code to develop cool stuff with Marvin. With step-by-step tutorials, anyone can create nice projects with Marvin.
Dutch idea
Spiritual father of Marvin is Niels Stamhuis, who started working for RDM Makerspace after studying product design at TU Delft. Stamhuis: "With the Internet of Things continuing to grow every day, making sure everyone can start working with it is the best way we can encourage this development."
Kickstarter
The European version of the Marvin board is available for a backing of 70 euros. Larger kits cost 80 euros or more for 'Kickstarter backers'. The crowdfunding campaign for Marvin runs until 2 December 2016.

On the agenda for the 8 December 2016 meeting - Workshop on LoRa and Use Case "Various LoRa deployments" Thomas Telkamp(Telkamp - Research & Development) has presented LoRa, LoRaWAN, and the challenges of long-range networking in shared spectrum
LoRa (slide 5) is the modulation technology used for long-range communication with low power requirements to support the transfer of small data volumes. It uses license-exempt spectrum, which is not harmonised around the globe. Frequencies in use are 433, 868, 915 MHz (slide 30), dependent on the region. The robustness of the modulation is explained in slides 8-20. Spreading factors (FS) provide optimum operation depending on the required distance between stations. Slides 20 and 21 show the relation between distance, bitrate (293-5469 bit/s) and channel airtime occupation.
Each LoRa channel is 125 kHz and 8 channels are used. A 250 kHz LoRa and 200 kHz FSK channel is also used for higher bitrates (11 kbit/s and 50 kbit/s).
Slide 7 depicts the architecture of a LoRaWAN or Low Power Wide Area Network (LPWAN). The sensors are attached to LoRa-RF and LoRaMAC units (slide 25).
Sensors communicate to Concentrator/Gateway units that bridge the data to TCP/IP SSL over 3G or Ethernet backhaul networks (slides 26 and 27).
also a Use Case: LoRa deployments in agriculture, water management, and logisticsby Pieter Hoenderken Het Internethuis B.V.
Pieter Hoenderken, CTO, Het Internet Huis B.V., present with his wife Anita (CEOCEO, Het Internet Huis B.V. took us to a pletoria of applications all using LoRa. In the applications he intended the use of 4G networks, but found that it was prohibitive because of the cost, so he uses LoRa.
He looks for customer needs and either makes a generic solution or delivers a solution on time/material basis.
Agriculture 1. A cooperative dairy chain pays farmers one and a half cents more for cows that are held 720 hours per year in the meadow. With the current technolgy, cows can decide themselves when they want to be milked at the indoor automated milking machine. The farmer needs to proof that his cows spend a sufficiently amount of time in the meadow. Pieter solved it by having a tag that can be detected when it passes a gate. When the cow passes the inner gate first followed by passing the outer gates, the timer for the cow being on the meadow starts ticking. It does so until the cow passes the gates in the opposite sequence.
Agriculture 2. Hay scalding is a high expense for insurance companies; they like to get a monitoring system to prevent fires. The old method was calling a service that has a probe for measuring internal hay temperatures. But that is expensive. By placing a sensor with LoRa in the hay stacks, a more efficient method is obtained.
Agriculture 3. A bank leases land to farmers. When the farmers fail to add sufficient nutrition to the land, the value of the land decreases. Hence the bank monitors the condition of the land through LoRa sensors at a certain depth in the land.
Agriculture 4. To ease the burden of having a good supply of Diesel Oil on the land and payment based on usage, a simple method is implemented that reports the amount of Diesel withdrawn. Then the oil company sends a bill for that amount. The total amount of delivered oil is eventual established by the calibrated meters at the delivery truck.
Agriculture 5. Alpaca's produce a very fine kind of wool; it is much softer than wool from sheep. The animals are a popular target for criminals. By having a LoRa device with position indication in their rennet stomach (it will stay there for life) they can generate an alarm when the animals are outside the premises of the farm.
Water management. To monitor sensors in monitoring wells, the cost would be € 1500 for a sensor and a SIM card. With a LoRa sensor this can be brought back to € 800 a month.
The Internet House in Doetichem currently has 17 projects.
Recent developments were seen at the Mobile World Congress, held in Barcelona at the end of February 2017, many eyes were on new developments in LoRa networks.
Indeed, the number of companies, which are getting into this technology, is growing incredibly fast.

Description
The Internet of Things (IoT) is an umbrella for various
technologies, use-cases, and business models.
Anne van Otterloo KIVI Telecom will give an overview of this in the introduction.
We will then zoom in on LoRa technology, explaining its structure, composition of components with applications.
LoRa is a Low Power Long Range radio technology, for which KPN has built a covering network in
the Netherlands; over this,
sensors can communicate for years without replacing the battery.
Pieter van Nieuwaal and Dirk Gooris (IoT pioneers) will discuss the
radio technology behind LoRa, the modules and gateways used for LoRa
communication, and how one can build one's own services. After
there will be a demonstration and everyone can check out the
components.
Jasper Kuin (new business development manager IoT, KPN) will explain
why a nationwide LoRa network is important, how the
development of new services on it is facilitated, and explain a
number of use-case examples.
