LoRa en LoRaWAN zijn een afkorting voor “Long Range Radio”. In 2009, it was demonstrated to the world by a start-up French company Cycleo as a spread spectrum modulation technology. The technology is based on linear frequency modulation (CSS).
The creation of LoRaWAN began after Semtech acquired Cycleo for $5 million in March 2012. The first LoRaWAN specification was co-founded by IBM Semtech and Actility.
1. What is LoRa technology?
LoRa technology is a long-distance wireless transmission technology, while at the same time it has low energy consumption. It is also a kind of LPWAN communication technology. Momenteel, het gebruik van speciale spread spectrum-technologie verbetert de ontvangstgevoeligheid aanzienlijk en vergroot effectief de capaciteit van het systeem.
Het grootste voordeel is dat het een langere afstand kan overbruggen dan andere draadloze methoden, maar met een lager energieverbruik. Bovendien, De infrastructuurkosten zijn veel lager dan die van andere netwerken.
Het Amerikaanse bedrijf Semtech was de eerste die deze technologie adopteerde en verspreidde. Het doel is om gebruikers te voorzien van draadloze communicatiemiddelen die transmissie over lange afstanden en een laag energieverbruik mogelijk maken. LoRa-netwerk heeft 4 componenten: de terminal, wolk, poort, en server.
LoRa-technologie staat bekend om zijn capaciteiten over lange afstanden. Ik zal u als voorbeeld gegevens laten zien: met één gateway of basisstation, Lora kan honderden vierkante kilometers bestrijken.
2. What is LoRaWAN technology?
LoRaWAN is een remote wide area netwerkprotocol ontwikkeld door de LoRa. Het heeft een groot dekkingsgebied gemeten in kilometers. Dingen kunnen draadloos met internet worden verbonden met LoRaWAN-technologie. LoRaWAN heeft ook de internet van dingen (IoT) functies, tweerichtingscommunicatie mogelijk maken, mobiliteitsdiensten, enzovoort.
Het gebruikt het spectrum zonder licentie in de ISM-band om zowel het systeem als het protocol van het netwerk te definiëren.
3. What is LoRa Alliance?
In maart werd het LoRa Consortium opgericht 2015. Sinds de oprichting, de LoRaWAN-specificatie wordt voortdurend bijgewerkt, van versie 1.0.0 naar versie 1.0.2, en momenteel beschikbaar om te downloaden is de versie 1.0.2 juli afgerond 2016. LoRa Alliance is een internationale alliantieorganisatie zonder winstoogmerk. Het doel van deze organisatie is om het standaardisatieproces te bevorderen Netwerk met laag vermogen (LPWAN). Zoals je kan zien, the lead authors of the specification include N.Sernin and M.Uis of Semtech, T.Esich, and T.Ramp of IBM, and O.Sent of AcTIlty, all of whom are members of the Consortium’s board.
The members of the LoRa Alliance cover companies and collectives from all over the world, including equipment manufacturers, sensor manufacturers, chip manufacturers, innovative start-ups, enzovoort.
According to LoRa Alliance statistics in 2016, most European companies joined the alliance, followed by Asia-Pacific companies. Although it was only established more than two years, its alliance members more than 500, making the alliance quickly become a model in the Internet of things field. The members include IBM, Cisco, Foxconn, PK, Alibaba, Schneider, Boshi, SK Telecom, Orange, ZTE, and other industry leaders, as well as a large number of small and medium-sized enterprises.
As an organization that mainly aims to spread the technical standards in the first place, nowadays Lora Alliance is also trying hard to promote the market-oriented alliance of the industry.
The Alliance Secretary Committee is composed of four parts, which are responsible for technology development, strategic decision-making, marketing, and certification. The four committees perform their own duties but are interconnected, and are fully committed to the standardization of low-power wide-area networks. Onder hen, the strategy committee is in charge of the major strategic decisions of the alliance and the development of the planning alliance. The technical committee takes care of the certification and updating of technical annotations. The Accreditation Committee is responsible for the Alliance’s accreditation programs and testing specifications. The Marketing Committee is responsible for public relations, Promotie, and exhibitions.
4. What is the difference between LoRa and LoRaWAN?
LoRa is a communication technology that achieves long-distance coverage and low power consumption at the same time. LoRaWAN, the abbreviation of LoRa wide area network, is a communication protocol evolved by LoRa technology.
You can use LoRa technology without using LoRaWAN, but there are limitations in functionality and performance. LoRaWAN’s protocol can help build large networks on the basis of LoRa.
In het algemeen, LoRa is a physical layer transport technology that allows you to exchange information between devices. For adaptive data rates to work, symmetric uplink and downlink require adequate downlink capacity. These features make LoRaWAN have a very high capacity. The network can be deployed with minimal infrastructure, and when capacity is needed, more gateways can be added, data rates can be varied, cross-talk times can be reduced, and network capacity can be expanded by six to eight times.
5. What are the applications of LoRaWAN technology?
Eerst, increase production and simplify farming methods
The use of LoRaWAN for slimme landbouw production has become more and more popular. Since farmers can easily visualize and monitor their crops, infrastructuur, omgeving, and all the other things with smart sensors. So that they can make better decisions to increase efficiency and production, and simplify farming methods at the same time. IoT agricultural sensors are compact in size and can determine many parameters to understand environmental aspects. LoRaWAN is widely used in smart agriculture for its excellent ability to cover a wide arrange of rural areas, while at the same time it has low power consumption and extended battery life. Together with the LoRaWAN sensor, they can detect the soil environment and help farmers to make better crop planting decisions.
LoRaWAN gateway for smart agriculture
Momenteel, the application of IoT-related technologies in the field of smart agriculture is rapidly emerging. Based on LoRaWAN gateways and various LoRa sensing devices, data can be quickly and effectively collected, transmitted, verwerkt, en opgeslagen (such as monitoring plant growth-related environmental parameters); Through data analysis, farmers can take corresponding measures in a timely manner. Aan de andere kant, since agricultural land usually lacks wired energy supply and reliable network coverage, in de meeste gevallen, additional deployment of on-site connections and energy harvesting (such as solar energy) are required for Its power supply to realize information exchange between IoT nodes.
Seconde, accelerate urban development
LoRaWAN gateway is also widely used in urban. LoRa technology can make everyday connected lighting, waste removal, vehicle services and smarter.
LoRaWAN gateway for smart cities
The cost of LoRaWAN infrastructure is very low compared to other networks, which helps to reduce the overall cost of the smart city.
The long-distance coverage ability enables LoRaWAN technology to help cities overcome network coverage challenges. It can provide coverage that traditional Wifi solutions cannot.
Applying LoRa technology to street lighting systems can minimize electricity costs, and the fact that LoRa technology targets low cost and low power consumption can make street lighting systems more widely popularized.
LoRa technology also benefits smart parking systems, where users can share parking status with any LoRa-enabled device. With the blessing of this technology, the ordinary parking behavior of the city has evolved into a smart space that detects the absence, arrival, and departure of vehicles at the same time.
LoRa technology can also be used in various urban applications such as smart sensors, slimme camera's, and smart flood sensors.
Derde, monitoring and tracking, so that health is more guaranteed
LoRa technology is also suitable for medical applications because of its low cost, long-distance coverage, en een laag stroomverbruik. It has great benefits for improving health care and livelihoods.
