Kwisiqingatha sesibini sonyaka ka-2021, i-SpaceLacuna yase-Bhritane yaqalisa ukusebenzisa iteleskopu yerediyo e-Dwingeloo, e-Netherlands, ukubonisa i-LoRa emva enyangeni. Ngokuqinisekileyo olu yayiluvavanyo oluchukumisayo ngokomgangatho wokubanjwa kwedatha, njengoko omnye wemiyalezo ude uqulathe isakhelo esipheleleyo seLoRaWAN®.
Isantya seLacuna sisebenzisa iseti yeesathelayithi ze-orbit ye-Earth ephantsi ukufumana ulwazi oluvela kwi-sensors ezidityaniswe nezixhobo ze-LoRa ze-Semtech kunye nobuchwepheshe be-radio frequency frequency. Isathelayithi indanda phezu kweepali zomhlaba rhoqo kwimizuzu eli-100 kumphakamo wama-500 eekhilomitha. Njengoko umhlaba ujikeleza, iisathelayithi zigubungela umhlaba. I-LoRaWAN isetyenziswa ngamasathelayithi, agcina ubomi bebhetri, kwaye imiyalezo igcinwa ixesha elifutshane de idlule kwinethiwekhi yezikhululo zomhlaba. Idatha ke idluliselwe kwisicelo kwinethiwekhi yomhlaba okanye inokujongwa kwisicelo esisekwe kwiWebhu.
Ngeli xesha, isignali ye-LoRa ethunyelwe nge-lacuna Speed yahlala kwi-2.44 imizuzwana kwaye yamkelwa yi-chip efanayo, kunye nomgama wokusasaza malunga neekhilomitha ze-730,360, ezinokuthi zibe ngumgama omde wokuhanjiswa komyalezo we-LoRa ukuza kuthi ga ngoku.
Xa kuziwa kunxibelelwano lwesathelayithi olusekwe kubuchwephesha be-LoRa, isiganeko esibalulekileyo saphunyezwa kwinkomfa ye-TTN(TheThings Network) ngoFebruwari 2018, ebonisa ukuba kunokwenzeka ukuba i-LoRa isetyenziswe kwi-Intanethi yezinto zesathelayithi. Ngexesha lomboniso ophilayo, umamkeli uthathe imiqondiso yeLoRa kwisathelayithi ejikelezayo ephantsi.
Namhlanje, ukusebenzisa itekhnoloji ye-IoT yamandla aphantsi ekhoyo yoluhlu olude olunje nge-LoRa okanye i-NB-IoT ukubonelela ngonxibelelwano oluthe ngqo phakathi kwezixhobo ze-IoT kunye neesathelayithi ezikwi-orbit kwihlabathi liphela zinokuthathwa njengenxalenye yemarike ye-WAN yamandla aphantsi. Ezi teknoloji zisicelo esinomdla de ixabiso labo lezorhwebo lamkelwe ngokubanzi.
I-Semtech iqalise i-LR-FHSS ukuze igcwalise iGap yeMarike kuQhagamshelwano lwe-IoT
I-Semtech ibisebenza kwi-LR-FHSS kule minyaka imbalwa idlulileyo kwaye ibhengeze ngokusemthethweni ukongezwa kwenkxaso ye-LR-FHSS kwiqonga le-LoRa ngasekupheleni kuka-2021.
I-LR-FHSS ibizwa ngokuba yiLongRange – iFrequency Hopping SpreadSpectrum. NjengoLoRa, yitekhnoloji yokumodareyitha itekhnoloji enobuninzi bentsebenzo efanayo ne-LoRa, njengobuntununtunu, inkxaso ye-bandwidth, njl.
I-LR-FHSS ngokwethiyori iyakwazi ukuxhasa izigidi zeendawo eziphelayo, nto leyo eyandisa kakhulu umthamo wothungelwano kwaye isombulule ingxaki yokuxinana kwesiteshi ebikade inciphisa ukukhula kwe-LoRaWAN. Ukongeza, i-LR-FHSS ine-anti-interference ephezulu, inciphisa ukungqubana kwepakethe ngokuphucula ukusebenza kakuhle kwe-spectral, kwaye inamandla okumodareyitha i-uplink frequency hopping.
Ngokudityaniswa kwe-LR-FHSS, i-LoRa ifanelekile ngakumbi kwizicelo ezineetheminali ezixineneyo kunye neepakethe ezinkulu zedatha. Ke ngoko, inkqubo yesathelayithi yeLoRa eneempawu ezidityanisiweyo ze-LR-FHSS zineengenelo ezininzi:
1. Inokufikelela ngokuphindwe kalishumi kumthamo wetheminali weLoRa network.
2. Umgama wothumelo mde, ukuya kuthi ga kwi-600-1600km;
3. Ukuchasa ukungenelela okunamandla;
4. Iindleko eziphantsi ziye zaphunyezwa, kubandakanywa iindleko zolawulo kunye nokuthunyelwa (akukho mfuneko yokongeza i-hardware ekufuneka iphuhliswe kwaye izakhono zayo zokunxibelelana ngesathelayithi zikhoyo).
I-Semtech ye-LoRaSX1261, ii-transceivers ze-SX1262 kunye ne-LoRaEdge TM iiplatifomu, kunye ne-V2.1 ye-design ye-reference reference, sele ixhaswa yi-lr-fhss. Ngoko ke, kwizicelo ezisebenzayo, ukuphuculwa kwesoftware kunye nokutshintshwa kwe-terminal ye-LoRa kunye nesango kunokuqala ukuphucula umthamo wenethiwekhi kunye nokukwazi ukuchasana nokuphazamiseka. Kwiinethiwekhi ze-LoRaWAN apho isango le-V2.1 lisetyenzisiwe, abaqhubi banokwenza umsebenzi omtsha ngokusebenzisa ukuphuculwa kwe-firmware elula yesango.
I-LR edibeneyo - FHSS
I-LoRa iyaqhubeka nokwandisa iPotfoliyo ye-App yayo
IBergInsight, iziko lophando lwentengiso ye-Intanethi yeZinto, likhuphe ingxelo yophando ngesathelayithi iot. Idatha ibonise ukuba ngaphandle kwempembelelo embi ye-COVID-19, inani labasebenzisi besathelayithi yehlabathi lisakhule laya kutsho kwi-3.4 yezigidi ngo-2020. ngo-2025.
Ngoku, yi-10% kuphela yemimandla yehlabathi ekwaziyo ukufikelela kwiinkonzo zonxibelelwano ngesathelayithi, nto leyo ebonelela ngendawo yokuthengisa ebanzi yophuhliso lwesathelayithi iot kwakunye nethuba lesathelayithi iot yamandla aphantsi.
I-LR-FHSS iya kuqhuba nokusasazwa kwe-LoRa kwihlabathi jikelele. Ukongezwa kweNKXASO ye-LR-FHSS kwi-platform ye-LoRa ayiyi kunceda kuphela ukubonelela ngeendleko ezisebenzayo, ukudibanisa indawo yonke kwiindawo ezikude, kodwa kwakhona kuphawula inyathelo elibalulekileyo lokusasazwa kwe-iot kwiindawo ezixineneyo. Iya kukhuthaza ngakumbi ukusasazwa kweLoRa kwihlabathi kwaye yandise ngakumbi usetyenziso oluyilayo:

Yandisa uFundo lobunzulu obungaphakathi
Ukongeza ekwandiseni umthamo wothungelwano, i-LR-FHSS yenza ukuba iindawo ezinzulu zokuphela kwangaphakathi ngaphakathi kweziseko zophuhliso zothungelwano ezifanayo, inyuse ubungakanani beeprojekthi ezinkulu ze-iot. I-LoRa, umzekelo, yitekhnoloji ekhethwayo kwimakethi yeemitha ezihlakaniphile zehlabathi, kwaye ukugqunywa kwangaphakathi okuphuculweyo kuya komeleza ngakumbi isikhundla sayo.
Abadlali abaninzi naBaninzi kwiSatellite ye-Intanethi yeZinto eziphantsi kwamandla
IiProjekthi zeSatellite ze-LoRa zaphesheya ziyaqhubeka nokuvela
UMcKinsey uqikelele ukuba i-iot esekwe kwindawo ingaxabisa i-560 yeebhiliyoni zeedola ukuya kwi-850 yeebhiliyoni zeedola ngo-2025, mhlawumbi sesona sizathu siphambili sokuba kutheni iinkampani ezininzi zileqa imarike. Okwangoku, phantse uninzi lwabavelisi bacebise izicwangciso zothungelwano lwesathelayithi iot.
Ngokwembono yemarike yaphesheya, i-satellite iot yindawo ebalulekileyo yokwenziwa kwezinto ezintsha kwimarike ye-iot. I-LoRa, njengenxalenye ye-Intanethi yeZinto yamandla aphantsi, ibone inani lezicelo kwiimarike zaphesheya:
Ngo-2019, i-Space Lacuna kunye ne-Miromico zaqala iimvavanyo zorhwebo zeprojekthi ye-LoRa Satellite iot, eyathi yasetyenziswa ngempumelelo kwezolimo, ukubeka iliso kokusingqongileyo okanye ukulandelwa kwe-asethi kunyaka olandelayo. Ngokusebenzisa i-LoRaWAN, izixhobo ze-iot ezinebhetri zinokwandisa ubomi babo benkonzo kwaye zigcine iindleko zokusebenza kunye nokugcinwa.
I-IRNAS isebenzisana ne-Space Lacuna ukuhlola ukusetyenziswa okutsha kweteknoloji ye-LoRaWAN, kuquka ukulandelela izilwanyana zasendle e-Antarctica kunye ne-buoys usebenzisa inethiwekhi ye-LoRaWAN ukuhambisa uthungelwano oluxineneyo lwezinzwa kwindawo yaseLwandle ukuxhasa ukusetyenziswa kwe-moring kunye ne-rafting.
I-Swarm (efunyenwe yi-Space X) idibanise izixhobo ze-LoRa ze-Semtech kwizisombululo zokudibanisa ukuze zenze unxibelelwano lweendlela ezimbini phakathi kweesathelayithi ze-orbit ye-Earth ephantsi. Kuvulwe iimeko ezintsha zokusetyenziswa kwe-Intanethi yeZinto (IoT) kwi-Swarm kwiindawo ezinje ngezothutho, ezolimo, iimoto eziqhagamshelweyo kunye namandla.
I-Inmarsat ihlangene ne-Actility ukwenza inethiwekhi ye-Inmarsat LoRaWAN, iqonga elisekelwe kwinethiwekhi ye-backbone ye-Inmarsat ELERA eya kubonelela ngobutyebi bezisombululo kubathengi be-iot kumacandelo aquka ezolimo, amandla, i-oyile kunye negesi, imigodi kunye nempahla.
Ekugqibeleni
Kuyo yonke imarike yaphesheya, azikho kuphela izicelo ezininzi ezivuthiweyo zeprojekthi. I-Omnispace, i-EchoStarMobile, i-Lunark kunye nabanye abaninzi bazama ukusebenzisa inethiwekhi ye-LoRaWAN ukubonelela ngeenkonzo ze-iot ngexabiso eliphantsi, kunye nomthamo omkhulu kunye nokugubungela ngokubanzi.
Nangona itekhnoloji ye-LoRa ingasetyenziselwa ukugcwalisa izithuba kwiindawo ezisemaphandleni kunye nolwandle ezingenayo i-intanethi yendabuko, yindlela efanelekileyo yokujongana "ne-Intanethi yayo yonke into."
Nangona kunjalo, ngokwembono yemarike yasekhaya, uphuhliso lwe-LoRa kulo mba lusekwisiqalo. Xa kuthelekiswa naphesheya kolwandle, ijongene nobunzima obuninzi: kwicala lemfuno, i-inmarsat network coverage sele ilungile kakhulu kwaye idatha inokudluliselwa kumacala omabini, ngoko ayinamandla; Ngokwesicelo, i-China isanqongophele, ngakumbi igxile kwiiprojekthi zeekhonteyina. Ngenxa yezi zizathu zingentla, kunzima kumashishini asekhaya asekhaya ukukhuthaza ukusetyenziswa kwe-LR-FHSS. Ngokumalunga nenkunzi, iiprojekthi zolu hlobo zixhomekeke kakhulu kwigalelo lenkunzi ngenxa yokungaqiniseki okukhulu, iiprojekthi ezinkulu okanye ezincinci kunye nemijikelo emide.
