In onlangse jare, the industry has focused on technical features, standaard konstruksie, policy support, and other aspects of IoT technology communications. Maar, deur 2020, IoT communications have entered the stage of application cases and large-scale commercial use.
This article analyzes the short-term development of several major IoT communication technologies in the domestic market, including 5G, NB-IoT, LTE-Cat1, LoRa, Bluetooth, WiFi, and other technologies. The characteristics of these technologies, such as multi-technology development patterns, standaardisering van protokol, netwerk intelligensie, and application customization, will become more prominent as IoT technology continues to develop.
An introduction to IoT wireless technology
The development of Internet of Things (IoT) technology has led to a clearer understanding of the trends surrounding IoT communication. The foundation of IoT is the connectivity between devices, which requires communication technology to enable data exchange. Wired connections are not suitable for complex and large-scale IoT systems, thus wireless connections are essential.
Wireless communication technology has become the driving force behind IoT development, and is the fastest growing and most widely used form of communication technology today. The advantages of wireless communication technology include breakthroughs in time and space, less interference from external factors, hoër inligtingsekuriteit, and improved communication efficiency.
5G IoT -tegnologie
Volgens die voorspelling van IHS Markit, gedurende 2020-2035, wêreldwye reële BBP sal groei teen 'n gemiddelde jaarlikse groeikoers van 2.9%, waarvan 5G sal bydra 0.2% van die groei. Gedurende hierdie periode, 5G related industries can create a GDP of USD 2.1 biljoen jaarliks. 5g is 'n baie belangrike ekonomiese groeipunt van die wêreldekonomie, en sy bydrae tot die wêreldekonomie het die BBP van Indië bereik, die sewende grootste ekonomie ter wêreld. Hierdie voorspelling is onafskeidbaar van die werklike kommersialisering van 5G, wat ook die belangrikste deel van 5G is. Die ontwikkeling van 5G in my land sal die oorgang van kleinskaalse kommersiële gebruik tot stand bring 2019 vir grootskaalse kommersiële gebruik in 2020.
Die pan-vermaaklikheidsbedryf sal een van die eerste winsgewende bedrywe vir 5G-ontwikkeling wees. Wat pan-vermaak betref, onder die bestaande netwerk, die diep integrasie van lewendige uitsendingstegnologie met VR en AR is nie genoeg nie. In die toekoms, met die seën van 5G, regstreekse uitsaai -toepassings sal vinniger geïmplementeer word. Daarby, sedert laas jaar, verwante selfoonvervaardigers het agtereenvolgens 5G -slimfone vrygestel, soos Huawei, OPPO, Vivo, Xiaomi, en Samsung. 5G -selfone het werklik die voorspel tot kommersialisering geopen, en daar sal in die toekoms meer selfone wees. Verwante ondernemings sluit by hierdie weermag aan. Op grond hiervan, mobiele speletjies sal ook 'n vinnig groeiende en volwasse bedryf wees. Danksy die ontwikkeling van 5G, daar sal 'n kwalitatiewe sprong in interoperabiliteit wees.
5G het 'n groot impak op aanlynonderrig, telemedisyne, en telewerk. In die gesig van 2020 that started in “helmodus”, people have had a deep understanding of the rigidity of online education, telemedisyne, en telewerk sedert die begin van die jaar. Nadat u hierdie tyd beleef het, hierdie reeks toepassings kan 'n groter ontwikkeling inlui, en nuwe industriële geleenthede kom na vore.
NB-IoT IoT-tegnologie
Volgens relevante statistieke, NB-IoT has completed the coverage of more than 300 stede in China alleen. Die aantal stede in die wêreld is ten minste 600 stede. Die aantal NB-IoT-terminale neem ook vinnig toe. Tot nou toe, die wêreld Daar is reeds meer as 100 miljoen NB-IoT in bedryf. NB-IoT word wyd gebruik in slim landbou, slim medies, slim logistiek, slim stad, slim meterlesing en ander bedrywe. Meer slim toepassingscenario's is ook ontdek. Die aantal NB-IoT-terminale het jaarliks met tienmiljoene toegeneem. In onlangse jare, with the popularization of IoT technology, die groeikoers van NB-IoT-terminale sal vinniger en vinniger word.
Alhoewel NB-IoT op baie gebiede gebruik word, die grootste gebruikscenario's is slim meterlesing en slim brandbeskerming. 'N Groot aantal rookverklikkers is aan NB-IoT gekoppel, and smart water meters and smart gas meters are connected to NB-IoT. Even more than 10 million. NB-IoT technology appeared later than LoRa technology, but from 2019 onwards, NB-IoT gradually surpassed the usage of LoRa in some areas. NB-IoT has grown relatively fast and has become a major player in many IoT fields. The main wireless communication technology will also occupy a larger market share in the future.
According to relevant data, the popularity of NB-IoT has decreased compared with the past, maar NB-IoT het 'n aansienlike industriële skaal gevorm, en die groeikoers van NB-IoT het nie afgeneem nie. NB-IoT-tegnologie word deur meer en meer ondernemings aanvaar, en die gebruik van meer ondernemings het die herhaling van NB-IoT-tegnologie versnel en die prestasie van NB-IoT-verwante produkte verhoog. NB-IoT is gradually replacing the original 2G-related applications. In die toekoms, die dekkingsgebied van NB-IoT sal groter wees, die dekkingsgebied sal meer wees, en verskillende nuwe toepassingscenario's sal oopgemaak word.
LTE-kat 1 IoT-tegnologie
Volgens relevante statistieke, different cellular communication technologies use different frequencies in the Internet of Things. Narrowband network services account for 60% of all Internet of Things connections, and 4G Cat and 5G eMBB and other such high-speed communication services account for 10%, and the remaining 30% of the Internet of Things connections are some low-to-medium-rate communication connections, which are occupied by LTE Cat1 and eMTC. Many countries have begun to assemble 2G/3G networks. Under this trend, eMTC cannot achieve network construction in many countries. LTE Cat1 technology has already occupied the vast majority of this part of the market. LTE Cat1 also supports calls, so LTE Cat1 will have a place in the Internet of Things era.
Because it is in the early stage of commercialization, die ooreenstemmende toepassingscenario's en gevalle is skaars, maar met die verdere ontwikkeling van die bedryf, wanneer Kat 1 het meer toepassings ontwikkel en verwante scenario's het grootskaalse vereistes, hulle sal ook aantrek Die toetrede van meer vervaardigers en verskillende soorte produkte sal by die korporatiewe plan ingesluit word.
LoRa IoT -tegnologie
Na jare se ontwikkeling, LoRa het 'n volledige ekologie gevorm en het 'n magdom toepassings. Benewens verteenwoordigende metersaansoeke, LoRa has enterprise-level applications such as buildings, hotelle, parke, sekuriteit, stede, landbou, en omgewingsmonitering. The fields have already emerged.
Maar, based on the current limited growth rate in the field of enterprise-level Internet of Things, die ontwikkeling van nuwe toepassingsgebiede is van kardinale belang vir LoRa. Vir hierdie rede, verwante LoRa -ondernemings het ook begin om hul ontwikkelingsrigting aan te pas, probeer om die gebied van binnenshuise internet van dinge op verbruikersvlak te sny, dus het slimhuisprodukte natuurlik die belangrikste toepassingspunt geword. Daarby, smartphones, drabare produkte, ens. sal ook die ontwikkelingsdoelwitte van LoRa wees.
Aangesien daar 'n natuurlike versperring is tussen die internet van dinge op ondernemingsvlak en die internet van dinge op verbruikersvlak, it is difficult to smooth the cross-border consumer-level Internet of Things for enterprises originally engaged in the enterprise-level Internet of Things. Daarom, the development of the consumer-level Internet of Things is bound to cause Changes in the composition of the LoRa ecosystem, especially terminal providers and solution integrators in the middle and lower reaches of the industry chain, will be a group of brand-new industry chain companies, which are mainly related to smart communities, smart campuses, and smart homes. Die ontwikkeling van nuwe toepassingsvelde sal noodwendig lei tot die vorming van nuwe ekologie.
Bluetooth IoT -tegnologie
Soos die “kapillêre” in the application of IoT technology, na verwagting sal draadlose kommunikasie oor kort afstand 'n baie groot aanvraag in die huidige mark hê. Kombineer verskillende faktore soos spoed, kragverbruik, netwerk, koste, en maklike toegang tot die internet, Bluetooth sal ongetwyfeld sy waarde speel op die gebied van die kortafstand-draadlose verbinding van die Internet of Things.
As early as the beginning of last year, the Bluetooth Alliance announced that Bluetooth 5.1 introduced a new “direction-finding” function. This function can help the device clarify the direction of the Bluetooth signal and realize the positioning of the Bluetooth system with centimeter-level position accuracy, which solves the problem of the Internet of Things to a certain extent The problem of positioning and navigation.
This year, the Bluetooth 5.1 version will also continue to deepen, especially AOA/AOD positioning technology. AOA -posisioneringstegnologie is 'n gevorderde posisioneringstegnologie wat geskik is vir Bluetooth. In 2019, AOA -tegnologie word in Bluetooth -standaard ingeskryf, wat deur baie ondernemings verwelkom word op grond van Bluetooth -posisioneringstegnologie. Vervaardigers het hul perdekrag begin vergroot om verwante produkte te ontwikkel en aktief meer toepassingsmoontlikhede te ondersoek. Daar word verwag dat verwante toepassings in sal verskyn 202 produkte.
WiFi IoT -tegnologie
Heeltyd, with the inclusion of 802.11ax into the formal standard and the release of the WiFi 6 standard, it has been the contest between WiFi 6 en 5G. As 5G high-frequency signals are difficult to enter indoors, and operators’ traditional indoor distribution systems will also face large-scale upgrades or replacements in the 5G era, they still need to face the ever-developing video and Internet of Things services. The constantly “evolving” WiFi is used to divert traffic and become the traffic responsible for office and home environments. 5G exists in some large cities, especially in crowded scenarios to provide communication services, while 4G exists as a rigidly-needed technology. This shows that in the next few years, a pattern of 4G+5G+WiFi will be formed.
Huidiglik, with the continuous development of emerging industries such as IoT technology, terminals using Wi-Fi technology continue to grow. A set of data from the Wi-Fi Alliance shows that there are currently more than 9 billion Wi-Fi devices in use worldwide. It is estimated that more than 3 billion new Wi-Fi devices will be added each year in the future, and Wi-Fi 6 will gradually become the mainstream access technology.
Afsluiting
No road can connect all the vast land of the motherland, and no communication technology can complete the construction of the entire Internet of Things world alone. It requires the cooperation of various communication technologies to become possible. With the development of the Internet of Things, each technology is constantly updated and iterated. In this process, certain IoT technology may be eliminated from the competition, but in the end, it will still be a situation where communication technologies with different technical characteristics coexist.
Met die verdere grootskaalse ontwikkeling van IoT-tegnologie, die ontwikkelingstendens rondom die Internet of Things -kommunikasie het geleidelik duidelik geword, and the characteristics of multi-technology development patterns, standaardisering van protokol, netwerk intelligensie, en die aanpassing van toepassings sal al hoe meer prominent word.
