Let’s talk tech.
The Internet is a vast network that connects computers all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection. The Internet of Things is a development of this idea, but the word “thing” is carefully chosen as it can mean almost anything.
Internet of Things
The Internet of Things or ‘IoT’ is where we have objects or ‘things’ connected to the internet that sense something, create some data from what they have sensed and then do something with that data.
IoT applications are made using LoRaWAN and open up huge possibilities - dewin.tech is keen to focus on developing this technology in the agricultural and public sectors.
LoRa & LoRaWAN.
There are lots of different types of devices that can be used for IoT, and they can be thought of as belonging to different families that can work together. LoRa is a wireless technology and LoRaWAN is a way of linking sensor devices and applications together. LoRa is a low-power technology and transmits at a very low power compared to mobile phones, WiFi etc.
LoRa stands for ‘Long Range’ and LoRa devices are indeed able to transmit and receive data over large distances. WAN stands for ‘Wide-Area Network’. A LoRaWAN sensor device is a thing that combines:
One or more sensors to measure or detect things of interest
A LoRa radio transmitter and antenna
A small microcontroller that is programmed to perform the sensing, join on to the LoRaWAN network and send the data (possibly receiving some data and performing some other tasks)
And, usually, a battery power supply
Why LoRaWAN?
Long range.
We can place devices a long way from the receiving gateways - up to 10km in situations where we have good line of sight between the sensor device and the gateway.
Battery life.
Whilst current mobile phones may require a battery charge every day, it is common for LoRaWAN devices to have batteries that last for many months and perhaps even up to 10 years before requiring a recharge or replacement. It’s also possible to use solar charging to extend this indefinitely.
Data rates.
In order for LoRaWAN to be able to perform so well in terms of range and low power consumption, the trade-off is the amount of data that can be sent and how often. Data rates are slow and small, and it is enough for many use cases. However, a LoRaWAN device can easily send frequent environmental measurements, but there is not enough capacity to send a CCTV image, for example.
Scalable and affordable.
LoRaWAN devices are becoming more affordable and as such, large numbers of devices (each with multiple sensors) can be used to provide sensing over a wide area or for more fine-grained local measurement.
Gateways are becoming more widespread.
Gateways can handle a lot of sensor devices and pick up signals over a wide area. With the network that is commonly selected for innovation (described later), you don’t need to own a gateway to get started if you are in range of somebody else’s. Adding more gateways into an area improves the resilience of the application and spreads the network further
Security.
Your data from the sensor is never available by eavesdropping on the radio waves and is secure.
Self-monitoring.
Devices can send self-monitoring data or ‘telemetry’ as well as the sensor data as part of their payload. For example, they can send their own power supply levels to give an indication of when they may need batteries replacing or recharging.
