I ka hapalua ʻelua o 2021, ua hoʻohana mua ʻo SpaceLacuna i kahi kelepona lekiō ma Dwingeloo, Netherlands, e hōʻike iā LoRa mai ka mahina.He hoʻokolohua kupanaha kēia ma ke ʻano o ka maikaʻi o ka hopu ʻana i ka ʻikepili, ʻoiai ʻo kekahi o nā leka i loaʻa i kahi kiʻi LoRaWAN® piha.
Hoʻohana ʻo Lacuna Speed i kahi pūʻulu o nā satelite orbit honua haʻahaʻa no ka loaʻa ʻana o ka ʻike mai nā mea ʻike i hoʻohui ʻia me nā lako LoRa a Semtech a me ka ʻenehana lekiō.Holo ka satellite ma luna o nā kia o ka honua i kēlā me kēia 100 minuke ma kahi kiʻekiʻe o 500 mau kilomita.I ka pōʻai ʻana o ka honua, uhi ʻia ka honua i nā satelite.Hoʻohana ʻia ʻo LoRaWAN e nā satelite, kahi e mālama ai i ke ola pākaukau, a mālama ʻia nā memo no ka manawa pōkole a hiki i ka hele ʻana i kahi pūnaewele o nā kahua kahua.Hoʻouna ʻia ka ʻikepili i kahi noi ma kahi pūnaewele terrestrial a i ʻole hiki ke nānā ʻia ma kahi noi pūnaewele.
I kēia manawa, ua lōʻihi ka hōʻailona LoRa i hoʻouna ʻia e ka lacuna Speed no 2.44 kekona a ua loaʻa iā ia e ka pahu hoʻokahi, me kahi mamao hoʻolaha ma kahi o 730,360 mau kilomita, ʻo ia paha ka lōʻihi loa o ka hoʻouna ʻana i ka leka LoRa i kēia manawa.
I ka wā e pili ana i ke kamaʻilio satellite-ground e pili ana i ka ʻenehana LoRa, ua loaʻa kahi milestone ma ka hālāwai TTN (TheThings Network) i Pepeluali 2018, e hōʻike ana i ka hiki ke hoʻohana ʻia ʻo LoRa i ka pūnaewele satellite o nā mea.I ka wā o kahi hōʻike ola, ua ʻohi ka mea hoʻokipa i nā hōʻailona LoRa mai kahi satellite orbit haʻahaʻa.
I kēia lā, ʻo ka hoʻohana ʻana i nā ʻenehana IoT lōʻihi haʻahaʻa haʻahaʻa e like me LoRa a i ʻole NB-IoT e hāʻawi i ke kamaʻilio pololei ma waena o nā mea IoT a me nā satelite i ka orbit a puni ka honua hiki ke manaʻo ʻia he ʻāpana o ka mākeke WAN haʻahaʻa haʻahaʻa.He noi hoihoi kēia mau ʻenehana a hiki i ka ʻae ʻia ʻana o kā lākou waiwai kālepa.
Ua hoʻokuʻu ʻo Semtech iā LR-FHSS e hoʻopiha i ka mākeke mākeke ma IoT Connectivity
Ke hana nei ʻo Semtech ma LR-FHSS i nā makahiki i hala iho nei a hoʻolaha kūkala i ka hoʻohui ʻana o ke kākoʻo LR-FHSS i ke kahua LoRa i ka hopena o 2021.
Kapa ʻia ʻo LR-FHSS LongRange - Frequency Hopping SpreadSpectrum.E like me LoRa, he ʻenehana modulation layer kino me ka hapa nui o ka hana like me LoRa, e like me ka sensitivity, kākoʻo bandwidth, etc.
Hiki i ka LR-FHSS ke kākoʻo i nā miliona o nā node hope, e hoʻonui nui ana i ka hiki o ka pūnaewele a hoʻonā i ka pilikia hoʻopaʻa ʻana i ke kahawai i kaupalena ʻia ka ulu ʻana o LoRaWAN.Eia kekahi, LR-FHSS he anti-interference kiʻekiʻe, hoʻopau i ka hui ʻana o ka packet ma o ka hoʻomaikaʻi ʻana i ka pono spectral, a loaʻa iā ia ka uplink frequency hopping modulation.
Me ka hoʻohui pū ʻana o LR-FHSS, ʻoi aku ka maikaʻi o LoRa no nā noi me nā ʻāpana paʻa a me nā ʻikepili nui.No laila, ʻo ka papahana satellite LoRa me nā hiʻohiʻona LR-FHSS i hoʻohui ʻia he nui nā pono:
1. Hiki iā ia ke komo i ʻumi mau manawa i ka nui o ka mana o ka pūnaewele LoRa.
2. ʻOi aku ka lōʻihi o ka hoʻouna ʻana, a hiki i 600-1600km;
3. ʻOi aku ka ikaika anti-interference;
4. Ua loaʻa nā kumukūʻai haʻahaʻa, me nā kumukūʻai hoʻokele a me ka hoʻolaha ʻana (ʻaʻohe pono e hoʻomohala ʻia nā lako hana hou a loaʻa i kāna mau mea hiki ke kamaʻilio satellite).
Semtech's LoRaSX1261, SX1262 transceivers a me LoRaEdgeTM platforms, a me ka V2.1 puka ho'olālā kuhikuhi, ua kāko'o 'ia e lr-fhss.No laila, ma nā noi kūpono, hiki i ka hoʻomaikaʻi ʻana i ka polokalamu a me ka hoʻololi ʻana o ka pahu LoRa a me ka puka puka hiki ke hoʻomaikaʻi mua i ka hiki ʻana o ka pūnaewele a me ka hiki ke hoʻopilikia.No nā pūnaewele LoRaWAN kahi i kau ʻia ai ka ʻīpuka V2.1, hiki i nā mea hoʻohana ke hana i ka hana hou ma o ka hoʻomaikaʻi ʻana i ka firmware gateway maʻalahi.
LR hui pū ʻia - FHSS
Ke hoʻomau nei ʻo LoRa i ka hoʻonui ʻana i kāna Portfolio App
Ua hoʻokuʻu ʻo BergInsight, kahi keʻena noiʻi mākeke pūnaewele o nā mea, i kahi hōʻike noiʻi ma ka satellite iot.Ua hōʻike ʻia nā ʻikepili ʻoiai ʻo ka hopena maikaʻi ʻole o COVID-19, ua ulu mau ka nui o nā mea hoʻohana iot satellite honua i 3.4 miliona ma 2020. Manaʻo ʻia nā mea hoʻohana iot satellite honua e ulu ma kahi cagR o 35.8% i nā makahiki e hiki mai ana, a hiki i 15.7 miliona. i ka makahiki 2025.
I kēia manawa, ʻo 10% wale nō o nā wahi o ka honua i loaʻa i nā lawelawe kamaʻilio satellite, kahi e hāʻawi ai i kahi ākea ākea no ka hoʻomohala ʻana i ka satellite iot a me kahi manawa kūpono no ka satellite iot.
E alakaʻi pū ʻo LR-FHSS i ka hoʻolaha ʻana o LoRa ma ka honua holoʻokoʻa.ʻAʻole kōkua ka hoʻohui ʻana o SUPPORT no LR-FHSS i ke kahua o LoRa i ka hoʻolako ʻana i nā kumu kūʻai ʻoi aku ka maikaʻi, ka hoʻopili ʻana i nā wahi mamao, akā e hōʻailona pū i kahi pae koʻikoʻi i ka hoʻolaha ʻana i ka iot nui ma nā wahi ākea.E hoʻolaha hou aku i ka hoʻolaha honua a LoRa a hoʻonui i nā noi hou:
-
Kākoʻo i nā lawelawe Satellite Iot
Hiki i ka LR-FHSS ke hoʻohui i nā satelite i nā wahi mamao loa o ka honua, e kākoʻo ana i ka hoʻonohonoho ʻana a me ka pono o ka lawe ʻana i ka ʻikepili o nā wahi me ka ʻole o ka uhi pūnaewele.Loaʻa nā hihia hoʻohana LoRa i ka nānā ʻana i nā holoholona hihiu, ʻimi ʻana i nā ipu ma luna o nā moku ma ke kai, ʻimi ʻana i nā holoholona i loko o ka pā, nā ʻōnaehana mahiʻai naʻauao e hoʻomaikaʻi i nā hua kanu, a me ka nānā ʻana i nā waiwai hoʻolaha honua e hoʻomaikaʻi ai i ka pono o ke kaulahao lako.

Kākoʻo no ka hoʻololi ʻikepili pinepine
Ma nā noi LoRa mua, e like me ka logistic a me ka huli waiwai, nā hale akamai a me nā paka, nā hale akamai, a me nā kaiāulu akamai, e hoʻonui nui ʻia ka helu o LoRa modulated semaphores i ka lewa ma muli o nā hōʻailona lōʻihi a me nā hoʻololi hōʻailona pinepine i kēia mau noi.Hiki ke hoʻopau ʻia ka pilikia o ka hoʻomohala ʻana o LoRaWAN ma ka hoʻomaikaʻi ʻana i nā terminal LoRa a me ka hoʻololi ʻana i nā ʻīpuka.

Hoʻonui i ka uhi hohonu o loko
Ma waho aʻe o ka hoʻonui ʻana i ka hiki ʻana o ka pūnaewele, hiki i ka LR-FHSS ke hāʻawi i ka hohonu hohonu o nā node i loko o ka ʻoihana pūnaewele like, e hoʻonui ana i ka scalability o nā papahana iot nui.ʻO LoRa, no ka laʻana, ʻo ia ka ʻenehana koho i ka mākeke mika akamai honua, a ʻo ka hoʻonui ʻia ʻana o ka uhi o loko e hoʻoikaika hou i kona kūlana.
ʻOi aku ka nui o nā mea pāʻani ma ka Pūnaewele Satellite Haʻahaʻa o nā mea
Hoʻomau ʻia nā papahana Satellite LoRa i waho
Ua wānana ʻo McKinsey he $560 biliona a hiki i $850 biliona e 2025, ʻo ia paha ke kumu nui o ka nui o nā hui e alualu nei i ka mākeke.I kēia manawa, kokoke i ka nui o nā mea hana i hoʻolālā i nā hoʻolālā pūnaewele satellite iot.
Mai ka hiʻohiʻona o ka mākeke o waho, ʻo satellite iot kahi wahi koʻikoʻi o ka hana hou i ka mākeke iot.Ua ʻike ʻo LoRa, ma ke ʻano he haʻahaʻa haʻahaʻa satellite Internet of Things, i kekahi mau noi ma nā mākeke o waho.
I ka makahiki 2019, ua hoʻomaka ʻo Space Lacuna a me Miromico i nā hoʻokolohua pāʻoihana o ka papahana LoRa Satellite iot, i hoʻohana maikaʻi ʻia i ka mahiʻai, ka nānā ʻana i ke kaiapuni a i ʻole ka nānā ʻana i nā waiwai i ka makahiki aʻe.Ma ka hoʻohana ʻana iā LoRaWAN, hiki i nā mea hana iot ke hoʻonui i ko lākou ola lawelawe a mālama i nā kumukūʻai hana a mālama.
Ua hui pū ʻo IRNAS me Space Lacuna e ʻimi i nā hoʻohana hou no ka ʻenehana LoRaWAN, me ka nānā ʻana i nā holoholona hihiu ma Antarctica a me nā buoys me ka hoʻohana ʻana i ka pūnaewele ʻo LoRaWAN e hoʻolalelale i nā ʻupena paʻa o nā mea ʻike i loko o ke kai moana e kākoʻo i nā noi mooring a me ka rafting.
Ua hoʻohui ʻo Swarm (loaʻa iā Space X) i nā polokalamu LoRa o Semtech i loko o kāna mau hoʻonā hoʻohui e hiki ai ke kamaʻilio ʻelua ala ma waena o nā satelite orbit honua haʻahaʻa.Wehe ʻia nā hiʻohiʻona hoʻohana hou o ka Internet of Things (IoT) no Swarm ma nā wahi e like me ka logistic, ka mahiʻai, nā kaʻa pili a me ka ikehu.
Ua hui pū ʻo Inmarsat me Actility e hoʻokumu i ka Inmarsat LoRaWAN network, kahi kahua i hoʻokumu ʻia ma ka Inmarsat ELERA backbone network e hāʻawi i ka waiwai o nā hopena no nā mea kūʻai iot i nā ʻāpana e pili ana i ka mahiʻai, ka mana, ka aila a me ke kinoea, ka mining a me ka logistics.
I ka hopena
I loko o ka mākeke o waho, ʻaʻole nui wale nā noi makua o ka papahana.Ke hoʻāʻo nei ʻo Omnispace, EchoStarMobile, Lunark a me nā mea ʻē aʻe e hoʻohana i ka pūnaewele o LoRaWAN e hāʻawi i nā lawelawe iot ma ke kumukūʻai haʻahaʻa, me ka nui o ka nui a me ka uhi ākea.
ʻOiai hiki ke hoʻohana ʻia ka ʻenehana LoRa e hoʻopiha i nā āpau i nā wahi kuaʻāina a me nā moana i nele i ka uhi pūnaewele kahiko, he ala maikaʻi loa ia e kamaʻilio ai i ka "Internet of everything."
Eia nō naʻe, mai ka manaʻo o ka mākeke kūloko, ʻo ka hoʻomohala ʻana o LoRa i kēia ʻano aia nō i kona wā kamaliʻi.Ke hoʻohālikelike ʻia me nā ʻāina ʻē, ʻoi aku ka nui o nā pilikia: ma ka ʻaoʻao koi, ua maikaʻi loa ka uhi ʻana o ka pūnaewele inmarsat a hiki ke hoʻoili ʻia ka ʻikepili ma nā ʻaoʻao ʻelua, no laila ʻaʻole ikaika;I ka ʻōlelo o ka noi, ua kaupalena ʻia ʻo Kina, e kālele ana i nā papahana pahu.I ka nānā ʻana i nā kumu i luna aʻe nei, paʻakikī i nā ʻoihana ukali kūloko e hoʻolaha i ka noi o LR-FHSS.Ma ke ʻano o ke kālā, ʻo nā papahana o kēia ʻano e hilinaʻi nui ʻia i ka hoʻokomo kālā ma muli o nā kānalua nui, nā papahana nui a liʻiliʻi paha a me nā pōʻai lōʻihi.
