I te haurua tuarua o te tau 2021, i whakamahia tuatahitia e te kamupene rererangi ātea o Peretānia, a SpaceLacuna, tētahi karu whakaata reo irirangi i Dwingeloo, i te Netherlands, hei whakaata i a LoRa mai i te marama. He whakamātautau whakamiharo tēnei mō te kounga o te hopu raraunga, i te mea kei roto i tētahi o ngā karere he anga LoRaWAN® katoa.
Ka whakamahia e Lacuna Speed tētahi huinga o ngā amiorangi porowhita-iti o te Ao hei whiwhi mōhiohio mai i ngā pūoko kua whakauruhia ki ngā taputapu LoRa a Semtech me te hangarau auau reo irirangi whenua. Ka rere te amiorangi ki runga ake i ngā pou o te Ao i ia 100 meneti i te teitei o te 500 kiromita. I te hurihuri o te Ao, ka kapi te ao i ngā amiorangi. Ka whakamahia te LoRaWAN e ngā amiorangi, e penapena ana i te ora o te pākahiko, ā, ka rongoatia ngā karere mō te wā poto tae noa ki te whiti i roto i tētahi whatunga o ngā teihana whenua. Kātahi ka tukuna ngā raraunga ki tētahi tono i runga i tētahi whatunga whenua, ka taea rānei te tiro i runga i tētahi tono tukutuku.
I tēnei wā, ko te tohu LoRa i tukuna e lacuna Speed i roa mō te 2.44 hēkona, ā, i riro mai i taua maramara anō, me te tawhiti horapa o te 730,360 kiromita, koinei pea te tawhiti roa rawa atu o te tuku karere LoRa tae noa ki tēnei wā.
Mō te whakawhitiwhiti kōrero amiorangi-whenua e ahu mai ana i te hangarau LoRa, i tutukihia tētahi tohu nui i te huihuinga TTN (TheThings Network) i te Hui-tanguru 2018, e whakaatu ana i te āheinga o te whakamahi i a LoRa i roto i te Ipurangi o ngā Mea amiorangi. I roto i tētahi whakaaturanga ora, i hopukina e te kaiwhiwhi ngā tohu LoRa mai i tētahi amiorangi porowhita-iti.
I ēnei rā, ko te whakamahi i ngā hangarau IoT tawhiti-roa iti-mana pēnei i a LoRa, NB-IoT rānei hei whakarato whakawhitiwhiti kōrero tika i waenga i ngā taputapu IoT me ngā amiorangi e porowhita ana i te ao, ka taea te kī he wāhanga o te mākete WAN iti-mana. He tono whakamere ēnei hangarau kia whakaaetia whānuitia rā anō ō rātou uara arumoni.
Kua whakarewahia e Semtech te LR-FHSS hei whakakī i te āputa mākete i roto i te hononga IoT
Kua mahi a Semtech i runga i te LR-FHSS mō ngā tau kua taha ake nei, ā, i panuitia mana te tāpiritanga o te tautoko LR-FHSS ki te tūāpapa LoRa i te mutunga o te tau 2021.
Ko te ingoa o te LR-FHSS ko LongRange – Frequency Hopping SpreadSpectrum. Pērā i a LoRa, he hangarau whakarerekētanga paparanga ā-tinana me te nuinga o ngā mahi rite ki a LoRa, pērā i te aro, te tautoko whānui, me ētahi atu.
E ai ki te ariā, ka taea e te LR-FHSS te tautoko i ngā miriona o ngā pona mutunga, ka nui ake te kaha o te whatunga, ka whakaoti hoki i te raruraru pupū o te hongere i whakawhāiti i te tipu o LoRaWAN i mua. Hei tāpiri, he nui te ātete-whakararuraru a te LR-FHSS, ka whakaiti i te tukinga mōkihi mā te whakapai ake i te whai huatanga o te hihi, ā, he kaha ki te whakarerekē i te auau hono-ake.
Mā te whakaurunga o te LR-FHSS, he pai ake te LoRa mō ngā tono he nui ngā pito me ngā mōkihi raraunga nui. Nō reira, he maha ngā painga o te kaupapa amiorangi LoRa me ngā āhuatanga LR-FHSS kua whakauruhia:
1. Ka taea e ia te uru atu ki te tekau ngā wā te nui ake o te kaha o te whatunga LoRa.
2. He roa ake te tawhiti tuku, tae atu ki te 600-1600km;
3. Kaha ake te ārai-pokanoa;
4. Kua iti ake ngā utu, tae atu ki ngā utu whakahaere me te whakatinanatanga (kāore he taputapu tāpiri e hiahiatia ana kia whakawhanakehia, ā, kei te wātea hoki ōna ake āheinga whakawhitiwhiti amiorangi).
Kua tautokona kētia ngā taputapu whakawhiti LoRaSX1261, SX1262 me ngā tūāpapa LoRaEdgeTM a Semtech, tae atu ki te hoahoa tohutoro kuwaha V2.1, e te lr-fhss. Nō reira, i roto i ngā mahi whaihua, mā te whakahou pūmanawa me te whakakapi i te pūrua me te kuwaha LoRa ka taea te whakapai ake i te kaha whatunga me te kaha ārai-whakararuraru. Mō ngā whatunga LoRaWAN kua whakatinanahia te kuwaha V2.1, ka taea e ngā kaiwhakahaere te whakahohe i te mahi hou mā te whakahou pūmanawa kuwaha ngāwari.
LR Whakauru – FHSS
Kei te Whakawhanui Tonu a LoRa i tana Pukapuka Taupānga
I tukuna e BergInsight, he whare rangahau mākete Ipurangi o ngā Mea, tētahi pūrongo rangahau mō te iotā amiorangi. E whakaatu ana ngā raraunga ahakoa te pānga kino o te COVID-19, i piki tonu te maha o ngā kaiwhakamahi iotā amiorangi o te ao ki te 3.4 miriona i te tau 2020. E matapaetia ana ka piki ake ngā kaiwhakamahi iotā amiorangi o te ao i te 35.8% i roto i ngā tau torutoru e whai ake nei, ka eke ki te 15.7 miriona i te tau 2025.
I tēnei wā, 10% noa iho o ngā rohe o te ao e whai wāhi atu ana ki ngā ratonga whakawhitiwhiti kōrero amiorangi, e whakarato ana i te wāhi mākete whānui mō te whakawhanaketanga o te ioT amiorangi me te whai wāhitanga hoki mō te ioT amiorangi iti-mana.
Mā te LR-FHSS anō hoki e akiaki te whakatinanatanga o LoRa puta noa i te ao. Mā te tāpiri i te TAUTOKO mō te LR-FHSS ki te tūāpapa o LoRa, ehara i te mea ka āwhina noa i a ia ki te whakarato hononga whai hua ake, whānui hoki ki ngā rohe tūmatanui, engari ka tohu hoki i tētahi taahiraa nui ki te whakatinanatanga o te ioT nui i ngā rohe taupori kikī. Ka whakatairanga anō i te whakatinanatanga o LoRa puta noa i te ao, ā, ka whakawhānui ake i ngā tono auaha:

Whakapai ake i te Taupoki Hōhonutanga o Roto
Haunga te whakawhānui ake i te kaha o te whatunga, ka taea e te LR-FHSS te whakawhānui ake i ngā pona pito o roto i roto i te hanganga whatunga kotahi, ka whakapiki ake i te tauine o ngā kaupapa ioT nui. Hei tauira, ko LoRa te hangarau whiriwhiri i roto i te mākete mita atamai o te ao, ā, mā te whakarei ake i te kapinga o roto ka whakapakari ake i tōna tūranga.
He maha ake ngā kaitākaro i roto i te Ipurangi Amiorangi Mana-iti o ngā Mea
Kei te Putanga Tonu Ngā Kaupapa Amiorangi LoRa ki Tāwāhi
Kua matapaetia e McKinsey ka eke te uara o te iot mō te wāhi ātea ki te $560 piriona ki te $850 piriona i te tau 2025, koinei pea te take matua e whai ana te tini o ngā kamupene i te mākete. I tēnei wā, tata ki te tekau mā rua ngā kaihanga kua whakaaro ki ngā mahere whatunga iot amiorangi.
Mai i te tirohanga a te mākete o tāwāhi, he wāhanga nui o te auahatanga te amiorangi ioT i roto i te mākete ioT. Hei wāhanga o te amiorangi iti-mana Ipurangi o ngā Mea, kua kitea e LoRa he maha ngā tono i roto i ngā mākete o tāwāhi:
I te tau 2019, i tīmata a Space Lacuna me Miromico i ngā whakamātautau arumoni o te kaupapa LoRa Satellite iot, i whakamahia angitu ki te ahuwhenua, te aroturuki taiao, te aroturuki rawa rānei i te tau i muri mai. Mā te whakamahi i te LoRaWAN, ka taea e ngā taputapu iot e whakamahia ana e te pākahiko te whakaroa i te roa o te wā mahi me te penapena i ngā utu whakahaere me te tiaki.
I mahi tahi a IRNAS me Space Lacuna ki te tūhura i ngā whakamahinga hou mō te hangarau LoRaWAN, tae atu ki te whai i ngā kararehe mohoao i Antarctica me ngā pōito mā te whakamahi i te whatunga a LoRaWAN hei whakatinana i ngā whatunga kikī o ngā pūoko i roto i te taiao Moana hei tautoko i ngā tono taunga me te rafting.
Kua whakauruhia e Swarm (i riro mai i a Space X) ngā taputapu LoRa a Semtech ki roto i āna otinga hononga hei whakahohe i te whakawhitiwhiti kōrero rua-ara i waenga i ngā amiorangi porowhita-iti o te Ao. Kua whakatuwherahia he horopaki whakamahinga Ipurangi o ngā Mea (IoT) hou mō Swarm i roto i ngā wāhanga pēnei i te kawe waka, te ahuwhenua, ngā motuka hono me te pūngao.
Kua mahi tahi a Inmarsat me Actility ki te hanga i te whatunga Inmarsat LoRaWAN, he tūāpapa e hangai ana ki te whatunga tuara o Inmarsat ELERA e whakarato ana i te maha o ngā otinga mō ngā kiritaki ioT i roto i ngā rāngai tae atu ki te ahuwhenua, te hiko, te hinu me te hau, te keri me te kawe waka.
I te mutunga
I te mākete o tāwāhi, ehara i te mea he maha noa ngā tono kua pakari o te kaupapa. Kei te ngana a Omnispace, EchoStarMobile, Lunark me te tini ke atu ki te whakamahi i te whatunga a LoRaWAN ki te tuku ratonga ioT i te utu iti ake, me te kaha nui ake me te whānuitanga o te kapinga.
Ahakoa ka taea hoki te whakamahi i te hangarau LoRa hei whakakī i ngā āputa i ngā wāhi taiwhenua me ngā moana kāore i te rongonui te Ipurangi, he huarahi pai tēnei hei aro atu ki te "Ipurangi o ngā mea katoa".
Heoi, mai i te tirohanga a te mākete o roto, kei te tīmatanga tonu te whanaketanga o LoRa i tēnei āhuatanga. Ki te whakatauritea ki tāwāhi, he nui ake ngā uauatanga e pā ana ki a ia: i te taha tono, he tino pai te kapinga whatunga inmarsat, ā, ka taea te tuku raraunga i ngā taha e rua, nō reira kāore i te kaha; Mō te tono, he iti tonu te whakamahinga o Haina, ko te arotahi nui ki ngā kaupapa ipu. I runga i ngā take i runga ake nei, he uaua ki ngā umanga amiorangi o roto te whakatairanga i te tono o LR-FHSS. Mō te pūtea, ko ngā kaupapa o tēnei momo e whakawhirinaki nui ana ki te whakaurunga pūtea nā te nui o ngā āwangawanga, ngā kaupapa nui, iti rānei, me ngā huringa roa.
