What is LoRa and it's role in Digitisation

In the very near future, one can be capable to monitoring every device which is in his vicinity. For example, we can manage the wastewater pumping station to the construction site equipment and animals too, everything can be networked, monitored, controlled and evaluated. In order to get the data monitored, a suitable transmission technology for machines (and animals) is needed. It should have long ranges and also the capability to  penetrate well through walls in order to get data from the last corner. In addition, a low power consumption is very important, so you do not constantly need to replace the batteries in difficult places. The major mobile service providers are setting up the NB-IoT or Narrowband IoT network for this - where it makes economic sense for them, and connected with transmission costs for each individual sensor or actuator. What would you say if you could determine the network coverage on your (city) terrain and flexibly expand, and on top of that save the transmission costs? The LoRaWAN (Long Range Wide Area Network) can offer you just these freedoms and much more.

 

Functionalities and working of LoRaWAN:

  • In a defined area, several gateways (the connection nodes) are attached to cover the entire area.
  • All things that are to be monitored or controlled are provided with sensors for measuring or actuators for controlling.
  • IoT database and software are configured to prepare the right data for the right people, or to perform automated actions.

LoRaWAN is characterised using following features:

  • Data transfer costs are very economical and takes place in the network you are able control.
  • The LoRaWAN standard is protected against data hijacking and hacking by several mechanisms.
  • The battery life is very long (many years depending on the application), because the LoRa standard is extremely energy-efficient.
  • LoRaWAN comes well through walls and has ranges (depending on terrain) of several kilo-meters.
  • Once you have set up a LoRaWAN in your area, you can quickly, easily and conveniently add more use cases.

This makes the LoRaWAN an ideal solution for regional/local machine networks. Here some examples:

LoRa in construction site networking:

In a construction site, Work will be comprised in many sites at the same time. Materials and tools will be disappeared and equipment can be missing, Sometimes unexpected material problems occur as a result of temperature fluctuations, the toilet facilities can be full. All this causes additional costs and dissatisfaction among employees.  

ECBM comes with a solution in these cases.

 

A local LoRaWAN makes it easy to monitor the entire construction site. If a device is not in its place, it can be located by a sensor. Another sensor monitors the temperatures on the construction site and reports critical values. Theft problems are also handled well thanks to the history of the network. From the fence to the containers, transmitters with alarm contacts are installed on all gates, doors and windows to monitor them in real time. You, or the security service, immediately receive a message on your smartphone when a gate is opened. Burglars therefore have little time. Furthermore, the networking of the construction site contributes to the safety of the employees. If you equip a working staff with a dead man's alarm, you can be able to extend your help immediately in the event of an accident. And the full toilet is no longer a problem, because a sensor for level measurement is fixed and it signals timely for emptying. Thanks to the long-lasting batteries, the sensors can be installed anywhere without much effort. And because sensors can be easily connected as needed, the network adapts to the requirements from site to site. And when a construction site is completed, the entire network can be taken to the next construction site.

Sewage system monitoring without physical contact in to the canal:

Currently, monitoring of the sewage system includes with a high cost of time and effort. At each measuring point, a construction site must be shut off, and two wastewater experts must descend and determine the data. Subsequently, the construction site is dismantled and the data determined are noted. Thanks to LoRaWAN, this is now faster and with far less effort. Sensors are attached at the measuring points, which raise the amount of water, pressure, flow, velocity, temperature etc. and send them automatically. All that remains is to evaluate the data. This saves a considerable amount of time and money and does not hinder traffic. Above all, the LoRaWAN is characterised by its long range, because it is reliably transmits its data even in deep basements or shafts.

Networking in Farming / Smart agriculture:

ECBM enables each farm to build up its own LoRaWAN for a relatively low cost. Sensors are enabled to monitor both fields of plants and animals to produce optimal conditions. An example of this is the health of livestock. Until now it has been difficult for farmers to have a permanent overview of the health status of the animals. Again and again, diseases only occur when symptoms are visible and the disease has already progressed. A small sensor on the animal's ear helps the farmer to get rid of the situation. Now, the farmer can view all the data of the animals, such as body temperature, etc., at any time on his smart phone. In case of abnormalities, he can intervene directly. The high range and the strong batteries make the LoRaWAN the perfect technology for this, as the animals can easily move around the pasture with the sensors. And in there is no extra power connection required. In addition, with an expansion of the stock simply additional sensors can be switched to it, without the need of an external provider.

Smart city - build a city network with LoRaWAN:

While developing a city into a smart city, the installation of LoRaWAN is a great addition to mobile communications. All applications that do not consume large amounts of data can run on the city-owned machine network. Unlike the use of the mobile network, the city itself determines the area coverage, and can manage the collected data to the right people, apps or offices depending on their authorization.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The data collected from the sensors at the measuring points of waste water management are provided to the waterworks and the canal operators. The information about the levels of containers is notified, which can thereby optimise their routes. It is also possible to integrate intelligent electricity and water meters, which transmit the consumer data directly to the corresponding supplier. This eliminates the use of field workers and the residents no longer have to wait for reading at home. Traffic and street lighting can also be optimised, saving energy and protecting the environment. Traffic lights can be monitored by the traffic management and street lights can be turned into smart lights. LoRaWAN sensors can also be used for measuring the amount of fine dust in our way. For example, if you attach sensors that measure the fine dust amount to bicycles, they reliably transmit particulate matter data to the Environmental Agency on the path.

Here are the advantages of the LoRaWAN:

  • Network coverage can be determined by yourself.
  • Mobile and flexible.
  • No transmission costs applied.
  • Independent of mobile service providers.
  • High range and low energy consumption (battery life can be extended up to 15 years(max)). 

We would be happy to work with you to identify the potential application of LoRaWAN, as an alternative or as a supplement to other transmission technologies and to support you as needed in its design and use. Interested in getting touch to us, please write to: consulting@ecbm.me.
