LPWAN Technologies for Internet of Things (IoT) and M2M ScenariosPeter R. Egli
Rapid technological advances in the past made possible the miniaturization of network devices to meet the cost and power consumption requirements in IoT and M2M scenarios. What is missing in this picture is a radio technology with both long range capability and a very low cost footprint. Existing radio technologies such as 3G/4G or Short Range Radio do not aptly meet the requirements of IoT scenarios because they are either too expensive or are not able to provide the required range. Other wireless technologies are geared towards high bandwidth which is in most cases not a requirement for IoT.
Emerging LPWAN technologies such as ETSI LTN or LoRAWAN are poised for filling the gap by providing long range (up to 40km) and low power connectivity. These technologies allow low cost radio devices and operation thus enabling scaling up IoT applications.

Dash7 alliance protocol - where rfid meets wsnMaarten Weyn
The document discusses the DASH7 Alliance Protocol, which originated from ISO 18000-7 and describes wireless sensor and actuator network communications. It is now an open standard for ultra-low power mid-range sensor and actuator communication across sub-GHz bands. The IDLab research group at the University of Antwerp has been actively involved in the DASH7 Alliance since 2011, developing an open source protocol stack and hardware prototypes. The protocol uses a star network topology with simple routing to extend the range of gateways while minimizing energy usage.
The document discusses challenges with existing LTE IoT standards like LTE Cat M1 and NB-IoT in supporting real-time, low power networking. It proposes running the Haystack (DASH7) networking stack concurrently with TCP/IP on the same silicon to enable features like precision indoor location, peer-to-peer networking, and distributed applications while minimizing memory footprint impact. Using reference tags and RF fingerprinting, Haystack can provide indoor location precision of about 1 meter to complement wide area visibility from LTE. Overall Haystack aims to deliver a complete LPWAN-LAN connectivity solution for IoT use cases.
An overview of Haystack's security features for low power IoT networks. Unlike most IoT stacks, when Haystack invented DASH7, security was an a priori principle and led to the most secure networking stack available in the low power, wide area networking (LPWAN) space today.

LoRa is a low power wide area network technology that enables long range communication for internet of things devices. It uses a star-of-stars topology with end devices communicating with gateways using LoRa radio technology. Gateways are then connected to a central network server. LoRa supports bi-directional communication and uses frequency spreading to allow simultaneous communication on different data rates without interference. It provides encryption for secure communication and supports various device classes with different receive window capabilities. Unizen has expertise in developing solutions using LoRa technology.
LoRa is a wireless communication technology that uses chirp spread spectrum (CSS) modulation to enable long-range and low-power data transmission between devices over several kilometers outdoors or hundreds of meters indoors. It operates in unlicensed radio frequency bands and supports applications requiring long-range communication like smart cities, industrial automation, and environmental monitoring. LoRaWAN is an open standard built on top of LoRa for secure bi-directional communication in low-power wide-area networks (LPWANs) that is widely adopted in the Internet of Things (IoT) industry.
Although many techniques exist to transfer data from the widely distributed sensors that make up the Internet of Things IoT e.g., using 3G 4G networks or cables , these methods are associated with prohibitively high costs, making them impractical for real life applications. LoRa Long Range modulation together with LoRaWAN LoRa Wide Area Networks communication protocol can represent a suitable candidate ensuring a high level of performance in wireless technologies. The objective is to contribute toward the realization of LoRa as a viable communication technology for applications that needs long range links and deployed in a distributed manner. The LoRaWAN networks are the evolution of wireless sensor networks directed to the IoT concept, which entails sensor connectivity to the Internet. LoRa technology is summarized by reviewing some aspects regarding the architecture, security and application of the technology.

IMPLEMENTATION OF AN INTELLIGENT MOTION DETECTORIRJET Journal
This document describes the implementation of an intelligent motion detector that can detect the direction of motion (left, right, up, down). It uses a Raspberry Pi to analyze signals from a 4x4 PIR sensor array. Python code is written to detect motion direction by analyzing timestamps from multiple motion sensors. When a sensor is activated, the timestamp is recorded. By looking at the sequence of timestamps, the direction of motion can be inferred. The code defines functions to detect motion in each direction by comparing the relative timestamps in the motion sensor arrays. When motion is detected, the direction is printed and the arrays are cleared.

What are the Benefits of LoRaWAN Technology?
Today, we talk about the seven benefits of LoRaWAN technology application.
In December 2021, LoRaWAN officially became the ITU International Standard for Low Power Wide Area Networks and has been endorsed by the International Telecommunication Union (ITU).
LoRaWAN is developed as an open standard and has been widely recognized by the low power wide area network community. The rapid adoption of this standard for global IoT low-power wide-area networks is a testament to its universality.
LoRaWAN is now a very popular LPWA communication standard that uses unlicensed radio spectrum in the ISM (Industrial, Scientific, Medical) band at frequencies ranging from approximately 433 MHz to 868 MHz, 915 MHz (standards vary around the world).
In the IoT connectivity environment, in addition to smart home networking and office space scenarios, many IoT devices will be connected and communicated in remote environments where the new environment will be inaccessible and require power connections due to M2M transmission coverage limitations.

Editor's Notes
End points: The endpoints are the elements of the LoRa network where the sensing or control is undertaken. They are normally remotely located.
LoRa gateway : The gateway receives the communications from the LoRa endpoints and then transfers them onto the backhaul system. This part of the LoRa network can be Ethernet, cellular or any other telecommunications link wired or wireless. The gateways are connected to the network server using standard IP connections. On this way the data uses a standard protocol, but can be connected to any telecommunications network, whether public or private. In view of the similarity of a LoRa network to that of a cellular one, LoRa gateways may often be co-located with a cellular base station. In this way they are able to use spare capacity on the backhaul network.
Server: The LoRa network server manages the network. The network server acts to eliminate duplicate packets, schedules acknowledgement, and adapts data rates. In view of the way in which it can be deployed and connected, makes it very easy to deploy a LoRa network.
Remote computer: a remote computer can then control the actions of the endpoints or collect data from them - the LoRa network being almost transparent.
In terms of the actual architecture for the LoRa network, the nodes are typically in a star-of-stars topology with gateways forming a transparent bridge. These relay messages between end-devices and a central network server in the backend.
Communication to end point nodes is generally bi-directional, but it is also possible to support multicast operation, and this is useful for features such as software upgrades and the like or other mass distribution messages.
There are many different needs to LoRa endpoints.
Class A - bi-directional end-devices: LoRaWAN class A endpoint devices provide bidirectional communications. To achieve this, each endpoint transmission is followed by two short downlink receive windows. The transmission slot scheduled by the particular endpoint is based upon the needs of the end point and also there is a small variation determined using a random time basis.LoRa Class A operation provides the lowest power option for end points that only require downlink communication from the server shortly after the end-device has sent an uplink transmission. Downlink communications from the server at any other time wait until the next scheduled uplink time.
Class B - bi-directional end-devices with scheduled receive slots: LoRa Class B devices provide the Class A functionality and in addition to this they open extra receive windows at scheduled times. To achieve the required synchronisation from the network, the endpoint receives a time synchronized Beacon from the gateway. This allows the server to know when the end-device is listening.
Class C - bi-directional end-devices with maximal receive slots: LoRa Class C devices provide nearly continuously open receive windows. They only closed when the endpoint is transmitting. This type of endpoint is suitable where large amounts of data are needed to be received rather than transmitted.
LoRa network security
The issue of network security is becoming increasingly important. As such LoRa networks require high levels of security to prevent disruption of any systems.
To achieve the required levels of security for LoRa networks, several layers of encryption have been employed:
Unique Network key (EUI64) and ensure security on network level
Unique Application key (EUI64) ensure end to end security on application level
Device specific key (EUI128)
