Mu gice cya kabiri cya 2021, icyogajuru cy’Ubwongereza cyatangije SpaceLacuna yabanje gukoresha telesikope ya radiyo i Dwingeloo, mu Buholandi, kugira ngo yerekane LoRa inyuma y'ukwezi.Ibi rwose byari igeragezwa rishimishije ukurikije ubwiza bwo gufata amakuru, kuko bumwe mubutumwa bwarimo ikadiri yuzuye ya LoRaWAN®.
Umuvuduko wa Lacuna ukoresha urutonde rwa satelite yo hasi yisi kugirango yakire amakuru aturuka kuri sensor yahujwe nibikoresho bya LoRa bya Semtech hamwe na tekinoroji ya radiyo ishingiye ku butaka.Icyogajuru kizenguruka inkingi z'isi buri minota 100 ku butumburuke bwa kilometero 500.Mugihe isi izunguruka, satelite itwikira isi.LoRaWAN ikoreshwa na satelite, ikiza ubuzima bwa bateri, kandi ubutumwa bubikwa mugihe gito kugeza igihe bunyuze murusobe rwibibuga.Ibyatanzwe noneho bigashyikirizwa porogaramu kurubuga rwisi cyangwa irashobora kurebwa kurubuga rushingiye kumurongo.
Kuriyi nshuro, ikimenyetso cya LoRa cyoherejwe na lacuna Umuvuduko cyamaze amasegonda 2.44 kandi cyakiriwe na chip imwe, gifite intera ikwirakwizwa rya kilometero 730.360, zishobora kuba intera ndende yo kohereza ubutumwa bwa LoRa kugeza ubu.
Ku bijyanye n'itumanaho rya satellite-ku butaka rishingiye ku ikoranabuhanga rya LoRa, intambwe yagezweho mu nama ya TTN (TheThings Network) muri Gashyantare 2018, byerekana ko bishoboka ko LoRa yakoreshwa kuri interineti ya satelite y'ibintu.Mugihe cyo kwerekana imbonankubone, uwakiriye yakuye ibimenyetso bya LoRa muri satelite yo hasi.
Uyu munsi, gukoresha ingufu zisanzwe zifite ingufu ndende ndende ya IoT nka LoRa cyangwa NB-IoT kugirango itange itumanaho ritaziguye hagati yibikoresho bya IoT na satelite mu kuzenguruka isi yose bishobora gufatwa nkigice cyisoko rya WAN rifite ingufu nke.Izi tekinoroji ni porogaramu ishimishije kugeza agaciro kabo k'ubucuruzi kemewe.
Semtech yatangije LR-FHSS kugirango yuzuze icyuho cyisoko muri IoT ihuza
Semtech imaze imyaka mike ikora kuri LR-FHSS itangaza ku mugaragaro ko hiyongereyeho inkunga ya LR-FHSS ku rubuga rwa LoRa mu mpera za 2021.
LR-FHSS yitwa LongRange - Ikwirakwizwa rya Frequency SpreadSpectrum.Kimwe na LoRa, ni tekinoroji yumubiri yo guhindura ibintu hamwe nibikorwa byinshi nka LoRa, nka sensibilité, infashanyo yumurongo, nibindi.
LR-FHSS ifite ubushobozi bwo gushyigikira amamiriyoni yanyuma, ibyo bikaba byongera cyane imiyoboro yumurongo kandi bigakemura ikibazo cyumuvuduko wumuyoboro wagabanije iterambere rya LoRaWAN.Mubyongeyeho, LR-FHSS ifite anti-intervention, igabanya kugongana kwa paki mugutezimbere imikorere, kandi ifite ubushobozi bwo guhinduranya modulisiyo.
Hamwe noguhuza LR-FHSS, LoRa irakwiriye cyane kubisabwa hamwe na terefone zuzuye hamwe namakuru manini.Kubwibyo, gahunda ya satelite ya LoRa hamwe na LR-FHSS ihuriweho ifite ibyiza byinshi:
1. Irashobora kubona inshuro icumi ubushobozi bwa terefone ya LoRa.
2. Intera yoherejwe ni ndende, kugeza kuri 600-1600km;
3. Kurwanya cyane kwivanga;
4. Ibiciro byo hasi byagezweho, harimo amafaranga yo gucunga no kohereza (nta byuma byongeweho bigomba gutezwa imbere kandi ubushobozi bwitumanaho bwabyo burahari).
Semtech's LoRaSX1261, SX1262 transceivers hamwe na platform ya LoRaEdgeTM, hamwe nigishushanyo mbonera cya V2.1, bimaze gushyigikirwa na lr-fhss.Kubwibyo, mubikorwa bifatika, kuzamura software no gusimbuza LoRa terminal na gateway birashobora kubanza kunoza ubushobozi bwurusobe nubushobozi bwo kurwanya interineti.Kumiyoboro ya LoRaWAN aho amarembo ya V2.1 yoherejwe, abashoramari barashobora gukora imikorere mishya binyuze mumashanyarazi yoroshye yo kuzamura amarembo.
Kwishyira hamwe LR - FHSS
LoRa ikomeje kwagura porogaramu yayo
BergInsight, ikigo cy’ubushakashatsi ku isoko rya interineti y’ibintu, yashyize ahagaragara raporo y’ubushakashatsi kuri satelite iot.Amakuru yerekanaga ko nubwo ingaruka mbi za COVID-19, umubare w’abakoresha iot ku isi yose ukomeje kwiyongera kugera kuri miliyoni 3.4 muri 2020. Biteganijwe ko abakoresha iot ku isi hose baziyongera kuri cagR ya 35.8% mu myaka mike iri imbere, bagera kuri miliyoni 15.7 muri 2025.
Kugeza ubu, 10% gusa by'uturere tw’isi ni bwo dushobora kubona serivisi z’itumanaho rya satellite, zitanga umwanya munini w’isoko ryo guteza imbere iot ya satelite ndetse n’amahirwe ya iot ifite ingufu nke.
LR-FHSS nayo izayobora kohereza LoRa kwisi yose.Kwiyongera kwa SUPPORT ya LR-FHSS kurubuga rwa LoRa ntabwo bizafasha gusa gutanga uburyo buhendutse, bwoguhuza ahantu hose mu turere twa kure, ariko kandi bizerekana intambwe igaragara yo kohereza iot nini mu turere dutuwe cyane.Bizakomeza guteza imbere ibikorwa bya LoRa kwisi yose no kurushaho kwagura ibikorwa bishya:
-
Shigikira Satelite Iot Serivisi
LR-FHSS ituma satelite ihuza uduce twinshi twa kure kwisi, igashyigikira imyanya nogukwirakwiza amakuru yibice bidafite umurongo.Imikoreshereze ya LoRa ikubiyemo gukurikirana inyamaswa zo mu gasozi, gushakisha ibikoresho ku mato yo mu nyanja, gushakisha amatungo mu rwuri, ibisubizo by’ubuhinzi bifite ubwenge hagamijwe kuzamura umusaruro w’ibihingwa, no gukurikirana umutungo ukwirakwizwa ku isi hagamijwe kunoza imikorere.
-
Inkunga yo guhanahana amakuru kenshi
Mubikorwa byabanjirije LoRa, nkibikoresho no gukurikirana umutungo, inyubako zifite ubwenge na parike, amazu yubwenge, hamwe n’abaturage bafite ubwenge, umubare wa LoRa wahinduwe mu kirere uziyongera cyane kubera ibimenyetso birebire ndetse no guhanahana ibimenyetso kenshi muri izi porogaramu.Ikibazo cyavuyemo ikibazo cyumuvuduko hamwe niterambere rya LoRaWAN nacyo gishobora gukemurwa no kuzamura ama LoRa no gusimbuza amarembo.

Kuzamura Ububiko Bwimbitse
Usibye kwagura ubushobozi bwurusobe, LR-FHSS ituma impera yimbere yimbere yimbere mubikorwa remezo bimwe, byongera ubunini bwimishinga minini iot.Urugero, LoRa, ni tekinoroji yo guhitamo ku isoko rya metero yubwenge ku isi, kandi kuzamura amazu yo mu nzu bizakomeza gushimangira umwanya wacyo.
Abakinnyi benshi kandi benshi mumashanyarazi make ya Satelite ya Internet yibintu
Mu mahanga Imishinga ya Satelite LoRa Komeza Emerge
McKinsey yahanuye ko iot ishingiye ku kirere ishobora kuba ifite agaciro ka miliyari 560 kugeza kuri miliyari 850 mu 2025, bikaba bishoboka ko ari yo mpamvu nyamukuru ituma ibigo byinshi biruka ku isoko.Kugeza ubu, inganda zigera ku icumi zasabye gahunda yo guhuza ibyogajuru iot.
Urebye ku isoko ryo hanze, icyogajuru iot nigice cyingenzi cyo guhanga udushya ku isoko rya iot.LoRa, nkigice cya enterineti ikoresha ingufu nke za interineti yibintu, yabonye porogaramu nyinshi kumasoko yo hanze:
Muri 2019, Space Lacuna na Miromico batangiye ibizamini byubucuruzi byumushinga wa LoRa Satellite iot, wakoreshejwe neza mubuhinzi, gukurikirana ibidukikije cyangwa gukurikirana umutungo umwaka ukurikira.Ukoresheje LoRaWAN, ibikoresho bya iot bikoresha ingufu za iot birashobora kongera igihe cya serivisi kandi bikabika kubikorwa no kubungabunga.
IRNAS yafatanije na Space Lacuna mu gushakisha uburyo bushya bwo gukoresha ikoranabuhanga rya LoRaWAN, harimo gukurikirana ibinyabuzima byo muri Antarctica hamwe na buoys bifashishije umuyoboro wa LoRaWAN kugira ngo bakoreshe imiyoboro yuzuye ya sensor mu bidukikije byo mu nyanja kugira ngo bashyigikire porogaramu.
Swarm (yaguzwe na Space X) yinjije ibikoresho bya LoRa ya Semtech mubisubizo byayo kugirango bishoboke itumanaho ryuburyo bubiri hagati ya satelite yo munsi yisi.Gufungura interineti nshya yibintu (IoT) ikoreshwa rya Swarm mubice nka logistique, ubuhinzi, imodoka zihuza ingufu ningufu.
Inmarsat yafatanije na Actility gushiraho umuyoboro wa Inmarsat LoRaWAN, urubuga rushingiye ku muyoboro w’umugongo wa Inmarsat ELERA uzatanga ibisubizo byinshi ku bakiriya ba iot mu nzego zirimo ubuhinzi, ingufu, peteroli na gaze, ubucukuzi bw'amabuye y'agaciro n'ibikoresho.
Amaherezo
Mu isoko ryo hanze, ntabwo hariho porogaramu nyinshi zikuze zumushinga.Omnispace, EchoStarMobile, Lunark nabandi benshi baragerageza gukoresha umuyoboro wa LoRaWAN kugirango utange serivisi za iot ku giciro gito, gifite ubushobozi bunini kandi bwagutse.
Nubwo ikoranabuhanga rya LoRa rishobora no gukoreshwa mu kuziba icyuho mu cyaro no mu nyanja zidafite interineti gakondo, ni inzira nziza yo gukemura “Internet ya byose.”
Nyamara, ukurikije isoko ryimbere mu gihugu, iterambere rya LoRa muriki gice riracyari mu ntangiriro.Ugereranije n’amahanga, ihura ningorane nyinshi: kuruhande rwibisabwa, imiyoboro ya inmarsat imaze kuba nziza cyane kandi amakuru ashobora koherezwa mubyerekezo byombi, ntabwo rero akomeye;Kubijyanye no gusaba, Ubushinwa buracyari buke, cyane cyane bwibanda kumishinga ya kontineri.Urebye impamvu zavuzwe haruguru, biragoye ko inganda zo mu gihugu ziteza imbere ikoreshwa rya LR-FHSS.Kubyerekeranye nigishoro, imishinga yubwoko ahanini iterwa nigishoro cyinjiza kubera ibintu bitazwi neza, imishinga minini cyangwa nto hamwe ninzinguzingo ndende.
