What is LoRaWAN Technology?
If you are working with networked devices, you may have heard of LoRaWAN at one time or another. It is a long-range network protocol. It enables the networking of things with the Internet even over longer ranges with low energy consumption. This solves one of the big problems that applications within the Internet of Things have faced up to now. With a battery life of up to five years and low maintenance costs for the sensor network, the LoRaWAN can be used for a wide variety of new applications.
This gives you a brief overview of what the LoRaWAN can do. In this article, we look at the architecture, key features of core technology, and the latest use cases where it is used.
What is LoRaWAN Technology?
The great thing about this technology is that it is based on an open standard. It uses an unlicensed spectrum as part of the ISM frequency band (“Industrial, Scientific, and Medical”, German: Industry, Science and Medicine). In Europe, the LoRaWAN uses the 868 MHz frequency range, while in the USA the 915 MHz frequency band is released. By using the unlicensed spectrum, it is very easy to set up and use your own network. Many telecommunications operators are already using LoRaWAN and offer the technology as part of their service offering in numerous countries worldwide. Comcast, KPN, Orange, SK Telecom and many other providers are actively implementing large-scale launches in their markets. This makes LoRaWAN even more interesting as a technology because it is compatible with the networks of different operators – large and small.
The LoRaWAN standard is monitored by the LoRa Alliance, which in turn consists of over 500 members who support the protocol and align many of their components, products, and services with LoRaWAN. These include companies such as MOKOSMART, ARM, Cisco, Microchip, and ST.
What distinguishes LoRa from LoRaWAN?
Tumblr media
Let’s start with the definition of LoRa – what is it exactly and how is it different from LoRaWAN? LoRa is a wireless technology similar to more common technologies such as Wi-Fi or WLAN, Bluetooth, LTE, and Zigbee. However, technology often does not cover all requirements, which means that users have to accept compromises. LoRa meets the demand for low-cost, battery-operated devices that can transmit data over long ranges. However, LoRa is not the right solution for the transmission of data over large bandwidths. LoRa is a technology that converts data to be transmitted into electromagnetic waves. This technique is also known as the chirped spread spectrum,it has been used in military and space communications for decades. It is due to the long communication range and the low susceptibility to interference.
LoRaWAN, on the other hand, is the MAC protocol for the network of high-performance LoRa nodes based on the Internet of Things, which cover long ranges and have low energy requirements. It uses the advantages of Lora described above and optimizes battery life and service quality for the LoRa nodes. The protocol is completely bidirectional, which ensures reliable message transmission (confirmation). End-to-end encryption is provided for security and data protection purposes, over-the-air registration of endnotes and multicast functions. The standard also ensures compatibility with LoRaWAN networks around the world.
LoRaWAN architecture mainly consists of four elements:
• End nodes
• Gateway (base stations/router)
• Network Server
• Application serverEnd nodes
End nodes are physical hardware devices that are equipped with sensor functions, a certain amount of computing power and a radio module for translating the data into a radio signal. These end devices can transmit data to the gateway and also receive it. Even with a small battery, they can last several years if they are put into deep sleep mode to optimize energy consumption.
When a device sends a message to the gateway, this is known as an “uplink”. The answer that the terminal receives from the gateway is called “downlink”. On this basis, a distinction is made between three types of end devices:
• Class A
• Class B
• Class C
Class A devices have the lowest energy consumption compared to the other two classes. However, these can only receive a downlink if they have sent an uplink. Class A devices are suitable for the transmission of data at time-based intervals (e.g. every 15 minutes) or for devices that send data based on events (e.g. if the temperature rises above 21 degrees or falls below 19 degrees).
Class B end nodes allow more message slots for downlinks than class A. This reduces message latency but is also less energy efficient.
Finally, class C has an ongoing receive window that is only closed when the device sends an uplink message. Therefore, this is the least energy-efficient variant, which often requires a constant current source to operate.
Gateways
Gateways are also known as modems or access points. A gateway is also a hardware device that receives all LoRaWAN messages from end devices. These messages are then converted into an array of bits that can be transmitted over conventional IP networks. The gateway is linked to the network server that transmits all messages.
Gateways are transparent and have limited computing power. More complex tasks are carried out in the network server. Depending on usage and type, gateways are available in two versions:
Gateways for indoor use, e.g. MKGW2-LW, MOKOSMART.
Network Server
All messages from the gateways are forwarded to the network server. This is where the more complicated data processing processes take place. The network server is responsible for:
1. Routing/forwarding messages to the right application;
2. The selection of the best gateway for downlink messages. This decision is usually made on the basis of a link quality indicator, which in turn is calculated via the RSSI (Received Signal Strength Indication) and the SNR (Signal to Noise Ratio) of packets that were previously  received;
3. Removing duplicate messages when received by multiple gateways;
4. Decrypting messages sent from end nodes and encrypting messages sent back to the nodes;
5. Gateways usually connect to the network server on an encrypted Internet Protocol (IP) link. The network usually includes the commissioning of the gateway and a monitoring interface that enables the network provider to manage gateways, remedy faults, monitor alarms, etc. …
Application server
The application server is where the IoT application is located – this is particularly useful for data captured using end devices. In most cases, application servers run via a private or public cloud, which is connected to the LoRaWAN network server and handles application-specific processing. The interface with the application server is controlled by the network server.
• LoRaWAN functions• Bi-directional communication
A terminal can transmit data to the gateway and also receive it according to the settings. These settings can also be called up within the application.
Localization
An interesting function of LoRaWAN is the localization without the need for GPS. This is particularly useful for tracking systems and sensors since it is battery-efficient and can be maintained more cheaply than conventional methods.
Scalability
LoRaWAN was designed for large IoT deployments in which thousands of devices are networked with a manageable number of gateways. These gateways can monitor multiple channels and process multiple messages at the same time.
Another important property of LoRaWAN is the speed with which data can be transmitted. There are different data rates that can be used for the transmission. These are also called spreading factors (SF). A slower transmission enables a longer and more reliable range.
For example, imagine you are talking to someone who is very close to you. You can speak very quickly in this situation and your counterpart understands everything you say. When you speak to someone who is far from you, you have to speak much slower to be understood. This principle also applies to the LoRaWAN protocol.
Adaptive Data Rate
With LoRaWAN, the network can also automatically optimize the speed at which the device transmits its data. This function is called the adaptive data rate (or ADR) and is particularly important to increase the capacity of a LoRaWAN network. ADR allows us to easily scale the network by adding another gateway. Because of this gateway, many end devices now automatically adjust their spreading factor. As a result, the individual devices are shorter “on the air”, which means more capacity for the network.
The adaptive data rate (abbreviation: ADR) is a simple mechanism that adjusts the data rate according to the following rules:
If the radio signal strength (also called “link budget”) is high, the data rate can be increased;
If the link budget is low, the data rate can be reduced.
Safety
It is important for every LPWAN to use a comprehensive security solution. LoRaWAN uses two levels of security: one for the network and one for the application. Network security ensures the authenticity of the end device in the network, while the application level ensures that the network operator does not have access to the application data of end-users. AES encryption is used for key exchange.
The network level is responsible for identifying the node. It checks whether a message really comes from a specific device and is also considered an integrity check. It can also encrypt MAC commands.
The application level is used for the decryption and encryption of payloads.
Both keys are encrypted with 128 bit AES in ECB mode.
Use cases and areas of application
LoRaWAN has found its place on the market in terms of applications and areas of application. Thanks to its unique properties, LoRaWAN is best suited for scenarios like these:
1. Access to electricity (electricity) is limited or restricted;
2. The locations are physically difficult to access or very remote;
3. The number of end devices is significantly higher compared to conventional mobile phone connections;
4. The end devices do not have to send messages continuously.

What is LoRa Technology
What is LoRa?
LoRa technology is a sort of new wireless protocol designed precisely for long-range connectivity and low-power communications. LoRa stands for Long Range Radio and it is mainly targeted for the Internet of Things (IoT) and M2M networks. This technology will allow multi-tenant or public networks to connect a number of applications running on the same network.
LoRa Alliance was designed to normalize LPWAN (Low Power Wide Area Networks) for IoT. A LoRa Technology and the open Lora WAN protocol enable smart IoT applications that solve some of the biggest challenges facing our planet: natural resource reduction, pollution control, disaster prevention, energy management, infrastructure efficiency, and more.
Each individual LoRa gateway has the capability to handle up to millions of nodes. The signals can extend a significant distance, which means that there is less structure required, making constructing a network faster and much cheaper to implement.
LoRa also features an adaptive data rate algorithm to help make the best use of the nodes network capacity and battery life. The LoRa protocol includes a number of different layers including application and device-level for secure communications, encryption at the network.
LoRa network architecture
A LoRa network contains several elements:
End points
The endpoints are the elements of the LoRa network where the control or sensing is undertaken. They are normally remotely located.
LoRa gateway
The gateway receives the infrastructures from the LoRa endpoints and then transfers them onto the backhaul system. This part of the LoRa network can be cellular, Ethernet or any other telecommunications link wireless or wired. The gateways are connected to the network server using typical IP connections. In this way the data uses a typical protocol but can be connected to any telecommunications network, whether private or public. In view of the likeness of a LoRa network to that of a cellular one, LoRaWAN gateways may often be co-located with a cellular base station. In this way, they are able to use extra capacity on the backhaul network.
LoRa Network Server
The LoRa network server succeeds in the network and as part of its function, it acts to remove duplicate packets, adapts data rates and schedules acknowledgment. In the assessment of the way in which it can be deployed and connected, makes it very easy to deploy a LoRa network.
Remote computer
Then, a remote computer can control the actions of the endpoints or collect data from the endpoints - the LoRa network being almost translucent.
In terms of the authentic architecture for the LoRa network, the nodes are typically in a star-of-stars topology with gateways forming a see-through bridge. These relay messages between the central network server and end-devices in the backend.
Communication to end point nodes is usually bi-directional, but it is also possible to support multicast operation, and this is useful for features such as the like or other mass distribution messages or software upgrades.
LoRa Technology basics
There are several key elements of LoRa technology. Some of its key features include the following:
Up to Millions of nodes
Long battery life; in spare of ten years
Long range; 15-20 km.
There are various elements to LoRa technology that provide the overall connectivity and functionality.
LoRa protocol stack: LoRa Alliance has also defined an open protocol stack. The creation of this open-source stack has allowed the concept of LoRa to raise because of all the different types of companies involved in LoRa development, deployment and use have been able to come together to create a low cost and easy to use solution for connectivity to all manners of connected IoT devices.
LoRa network design: (LoRaWAN):  Besides the RF elements of the LoRa wireless system, there are some other elements of the network architecture, including the presence of overall system architecture, Server, backhaul and the application computers. The overall architecture is often mentioned as LoRaWAN.
LoRa PHY / RF interface:  The LoRa physical layer or PHY is key to the operation of the system. It governs the aspects of the RF signal that is transmitted between the nodes or endpoints, i.e. LoRa gateway and the sensors are where signals are received. The physical layer or radio interface governs aspects of the signal including the modulation format, power levels, frequencies, signaling between the transmitting and receiving elements, and other related topics.
Features of LoRa Protocol
The following table displays some of the key features of the LoRa protocol such as modulation, capacity and range.
Tumblr media
LoRa network security
The issue of network security is becoming gradually important. As such LoRa networks require high levels of security to prevent the trouble of any systems.
Tumblr media
To attain the required levels of security for LoRa networks, several layers of encryption have been used:
Device specific key (EUI128).
The Unique Network key (EUI64) guarantees security on the network level.
Unique Application key (EUI64) certify end to end security.
Using these layers of encryption ensures that the LoRa network remains suitably secure.
LoRa Applications
LoRa wireless technology is preferably placed to be used in a variety of applications.
The long-range and low power capabilities mean that end points can be deployed in a wide variety of places, outside and inside buildings and still have the ability to be able to communicate with the gateway.
As the system is easy to deploy and it can be used for a large number of IoT, Internet Things, and machine to machine, applications, M2M.
Applications for LoRa wireless technology include inventory tracking, smart metering, vending machine data and monitoring; utility applications; automotive industry, etc. In fact, anywhere where control and data reporting may be needed.
LoRa technology is mainly attractive for many applications because of its long-range capability. Coverage is easy to provide and New nodes can easily be connected and activated.
LoRa Devices
Picocells & Gateways: Sensors capture then transmit data to gateways over distances that are close and far, outdoor and indoor, with the lowest power requirement
Transceivers & End-Nodes: Transceivers configured with LoRa Technology are fixed into sensor devices or end-nodes, designed for an assembly of industry applications.
LoRa Modulation:
LoRa Technology is the wireless modulation or physical (PHY) silicon layer, used to create the long-range communicatio­n link.
LoRa physical layer uses a form of spread spectrum modulation. The LoRa modulation system uses wide-band linear frequency-controlled pulses. The level of frequency increase or decrease over time is used to encode the data to be transmitted, such as; a form of chirp modulation.
This type of modulation enables LoRa wireless systems to demodulate signals that are 20dB below the noise floor when the demodulation is combined with forwarding error correction, FEC. When compared to a traditional FSK system; the link budget for a LoRa system can deliver an improvement of more than 25dB.
As a result of the point that the transmission is spread in a pseudo-random fashion, it may be difficult for non-Lora users to detect and appears like noise. This can support in the security of the system.
A further advantage of the system is that the chirp modulation and the system, in general, is tolerant of frequency offsets and as a result, it is possible to use a basic crystal oscillator with a 20-30 ppm acceptance rather than a temperature paying oscillator, TCXO. This can provide some good cost savings within the node electronic circuitry.
LoRaWAN:
Meanwhile, LoRa describes the lower physical layer, the upper networking layers were absent. LoRaWAN is one of the numerous protocols that were developed to describe the upper layers of the network. LoRaWAN is a cloud-based media access control (MAC) layer protocol but acts mainly as a network layer protocol to manage communication between end-node devices and LPWAN gateways, as steering protocol, maintained by the LoRa Alliance. LoRaWAN specification version 1.0 was released in June 2015.
LoRaWAN defines the system architecture and communication protocol for the network, while the LoRa physical layer allows the long-range communication link. LoRaWAN is also responsible for managing the data rate, power for all devices and communication frequencies. Devices in the network transmit whenever they have data available to send. Data transmitted by an end-node device is received by multiple gateways, which forward the data packets to a central network server. The server filters duplicate the packets, performs security checks, and manages the network. Data is then furthered to application servers. The technology shows high consistency for the modest load; however, it has some performance problems related to sending acknowledgments
Lora Alliance
As with many other systems, an industry body was set up to develop then promote the LoRa wireless system across the industry called the LoRa Alliance. It was launched in March 2015. As the Alliance states, it was set up to provide an open global standard for secure, carrier-grade IoT LPWAN connectivity.
Although LoRa had been essentially developed by Semtech, opening he standard out enabled it to be adopted by a wide number of companies, thereby growing the ecosystem and gaining significantly greater engagement, a wider variety of products and an overall increase in usage and acceptance.
The founding members of the LoRa Alliance include MOKOSMART,Actility, Cisco, Eolane, IBM, Kerlink, IMST, MultiTech, Sagemcom, Semtech, and Microchip Technology, as well as lead telecom operators: Bouygues Telecom, KPN, SingTel, Proximus, Swisscom, and FastNet (part of Telkom South Africa).
