Muhafu yechipiri ya2021, British space startup SpaceLacuna yakatanga kushandisa teresikopu yeredhiyo muDwingeloo, Netherlands, kuratidza LoRa kubva kumwedzi.Ichi chaive chiyedzo chinokatyamadza maererano nemhando yekutora data, seimwe yemameseji yaitove neyakazara LoRaWAN® furemu.
Lacuna Speed inoshandisa seti yepasi-Earth orbit satellite kuti igamuchire ruzivo kubva kune masensa akabatanidzwa neSemtech's LoRa michina uye pasi-based radio frequency tekinoroji.Satellite inofamba pamusoro pemapango epasi maminetsi ega ega 100 pahupamhi hwemakiromita mazana mashanu.Sezvo pasi rinotenderera, masatelliti anofukidza pasi rose.LoRaWAN inoshandiswa nema satellites, ayo anochengetedza hupenyu hwebhatiri, uye mameseji anochengetwa kwenguva pfupi kusvika adarika netiweki yezviteshi zvepasi.Iyo data inozoendeswa kune application pane yepasi network kana inogona kutariswa paWebhu-based application.
Panguva ino, chiratidzo cheLoRa chakatumirwa nelacuna Speed yakagara kwe2.44 seconds uye yakagamuchirwa nechipp chimwechete, ine chinhambwe chekuparadzira chemakiromita 730,360, inogona kunge iri chinhambwe chakareba cheLoRa kutumira meseji kusvika zvino.
Kana zvasvika kune satellite-pasi kutaurirana kwakavakirwa paLoRa tekinoroji, chiitiko chakakosha chakaitwa pamusangano weTTN (TheThings Network) muna Kukadzi 2018, zvichiratidza mukana weLoRa kushandiswa musatellite Internet yezvinhu.Munguva yekuratidzira mhenyu, mugamuchiri akatora masaini eLoRa kubva kune yakaderera-orbit satellite.
Nhasi, kusimudzira iripo yakaderera-simba-refu-refu IoT matekinoroji akadai seLoRa kana NB-IoT kuti ipe kutaurirana kwakananga pakati pemidziyo yeIoT nemasatelliti ari orbit kutenderera pasirese kunogona kutorwa sechikamu chemusika weWAN-simba.Aya matekinoroji inonakidza application kutozosvikira kukosha kwavo kwekutengesa kwagamuchirwa zvakanyanya.
Semtech Yakatangisa LR-FHSS Kuzadza Musika Gap muIoT Kubatana.
Semtech anga achishanda paLR-FHSS kwemakore mashoma apfuura uye akazivisa zviri pamutemo kuwedzera kweLR-FHSS rutsigiro kuLoRa papuratifomu mukupera kwa2021.
LR-FHSS inonzi LongRange - Frequency Hopping SpreadSpectrum.Kufanana neLoRa, iyo tekinoroji yekumisikidza tekinoroji ine akawanda ekuita kwakafanana neLoRa, sekunzwa, bandwidth rutsigiro, nezvimwe.
LR-FHSS ine theoretically inokwanisa kutsigira mamirioni emagumo node, iyo inowedzera zvakanyanya network network uye kugadzirisa dambudziko rekusangana kwechiteshi iro raimbotadzisa kukura kweLoRaWAN.Uye zvakare, LR-FHSS ine yakakwira anti-kupindira, inoderedza kudhumhana kwepaketi nekuvandudza spectral kunyatsoita, uye ine uplink frequency hopping modulation kugona.
Nekubatanidzwa kweLR-FHSS, LoRa inonyanya kukodzera maapplication ane dense terminals uye makuru data packet.Naizvozvo, iyo LoRa satellite chirongwa chine yakasanganiswa LR-FHSS maficha ane akawanda mabhenefiti:
1. Inogona kuwana zvakapetwa kagumi tembiricha yeLoRa network.
2. Kutapurirana kureba, kusvika 600-1600km;
3. Kurwisana kwakasimba-kupindira;
4. Mari yakaderera yakawanikwa, kusanganisira kutarisira uye kutengesa mari (hapana imwe hardware inoda kugadziridzwa uye iyo pachayo setiraiti yekukurukurirana masimba aripo).
Semtech's LoRaSX1261, SX1262 transceivers uye LoRaEdge TM mapuratifomu, pamwe chete neV2.1 gedhi rereferensi redhizaini, dzatotsigirwa nelr-fhss.Naizvozvo, mumashandisirwo anoshanda, kukwidziridzwa kwesoftware uye kutsiva LoRa terminal uye gedhi rinogona kutanga ravandudza network network uye anti-kupindira kugona.Kune LoRaWAN network uko V2.1 gedhi rakaiswa, vashandisi vanogona kugonesa basa idzva kuburikidza neyakapusa gedhi firmware upgrade.
Yakabatanidzwa LR - FHSS
LoRa Inoenderera Kuwedzera Iyo App Portfolio
BergInsight, iyo Internet yeZvinhu musika wekutsvagisa Institute, yakaburitsa mushumo wekutsvagisa pane satellite iot.Dhata yakaratidza kuti kunyangwe paine kushata kweCCIDID-19, huwandu hwevashandisi vepasi rose satellite iot hwakakura kusvika pamamirioni mazana matatu nemazana mana muna 2020. muna 2025.
Parizvino, 10% chete yematunhu epasi rose anokwanisa kuwana masevhisi ekutaurirana masevhisi, izvo zvinopa nzvimbo yakakura yemusika yekuvandudza satellite iot pamwe nemukana wepasi-simba satellite iot.
LR-FHSS ichafambisawo kuendeswa kweLoRa pasi rose.Kuwedzerwa kweSUPPORT yeLR-FHSS kupuratifomu yeLoRa haingobatsiri chete kupa inodhura-inoshanda, yekubatana kwese kwese kunzvimbo dziri kure, asi zvakare inomaka nhanho yakakosha yekuenda kwakakura-kuiswa iot munzvimbo dzine vanhu vakawanda.Ichawedzera kusimudzira kuendeswa kweLoRa kwepasirese uye nekuwedzera kuwedzera maapplication matsva:
-
Tsigira Satellite Iot Services
LR-FHSS inogonesa masetellite kuti abatanidze kunzvimbo dzakakura dziri kure dzepasi, achitsigira chinzvimbo uye data rekufambisa zvinodiwa munzvimbo dzisina kuvharwa netiweki.Makesi ekushandisa eLoRa anosanganisira kuronda mhuka dzesango, kutsvaga midziyo mungarava pagungwa, kutsvaga zvipfuyo kumafuro, mhinduro dzehungwaru dzekurima dzekuvandudza goho, uye kuteedzera midziyo yekugovera pasi rose kuvandudza kushanda kweketani.

Wedzera Indoor Depth Coverage
Pamusoro pekuwedzera simba retiweki, LR-FHSS inogonesa yakadzika yemukati magumo node mukati meiyo yakafanana network network, ichiwedzera scalability yemapurojekiti makuru e-iot.LoRa, semuenzaniso, ndiyo tekinoroji yesarudzo mumusika wepasi rose smart mita, uye yakagadziridzwa yekuvhara yemukati inosimbisa chinzvimbo chayo.
Vatambi Vanowedzera uye Vakawanda mune Yakaderera-simba Satellite Internet yezvinhu
Overseas LoRa Satellite Projects Ramba Richibuda
McKinsey akafanotaura kuti space-based iot inogona kunge yakakosha $560 bhiriyoni kusvika $850 bhiriyoni ne2025, icho chingave chiri chikonzero chikuru nei makambani mazhinji ari kudzingirira musika.Parizvino, vangangoita gumi nevaviri vevagadziri vakakurudzira satellite iot networking zvirongwa.
Kubva pamaonero emusika wekunze, satellite iot inzvimbo yakakosha yekuvandudza mumusika weiot.LoRa, sechikamu cheiyo yakaderera-simba satellite Internet yeZvinhu, yakaona akati wandei maapplication mumisika yekunze:
Muna 2019, Space Lacuna neMiromico vakatanga miedzo yekutengeserana yeLoRa Satellite iot project, iyo yakashandiswa zvakabudirira kune zvekurima, kutarisa kwezvakatipoteredza kana kutevedza midziyo gore rakatevera.Nekushandisa LoRaWAN, bhatiri-powered iot zvishandiso zvinogona kuwedzera hupenyu hwavo hwesevhisi uye kuchengetedza pakushandisa uye kugadzirisa mari.
IRNAS yakabatana neSpace Lacuna kuongorora mashandisirwo matsva eTekinoroji yeLoRaWAN, kusanganisira yekutevera mhuka dzesango muAntarctica uye mabhuoys achishandisa LoRaWAN's network kuendesa dhizaini network yemasensor munzvimbo yeMarine kutsigira kunyorera uye rafting.
Swarm (yakawanikwa neSpace X) yakabatanidza zvishandiso zveSemtech's LoRa mumhinduro dzayo dzekubatanidza kugonesa nzira mbiri dzekukurukurirana pakati pepasi-Earth orbit satellite.Yakavhura nyowani Internet yezvinhu (IoT) mashandisiro eSwarm munzvimbo dzakaita senge zvinhu, zvekurima, mota dzakabatana uye simba.
Inmarsat yakabatana neActility kugadzira iyo Inmarsat LoRaWAN network, chikuva chakavakirwa paInmarsat ELERA backbone network iyo ichapa hupfumi hwemhinduro kune iot vatengi muzvikamu zvinosanganisira zvekurima, simba, oiri uye gasi, migodhi uye zvinhu.
Pakupedzisira
Mumusika wese wemhiri kwemakungwa, hapangori maapplication akawanda epurojekiti.Omnispace, EchoStarMobile, Lunark nevamwe vazhinji vari kuyedza kukwirisa network yeLoRaWAN kuti ipe iot masevhisi nemutengo wakaderera, nehukuru hukuru uye kuvharika kwakafara.
Kunyangwe tekinoroji yeLoRa inogona zvakare kushandiswa kuzadza mapundu munzvimbo dzekumaruwa nemakungwa asina kuvharika kwechinyakare paInternet, inzira yakanaka yekugadzirisa "Internet yezvinhu zvese."
Nekudaro, kubva pakuona kwemusika wepamba, budiriro yeLoRa muchikamu ichi ichiri muhucheche.Kuenzaniswa nemhiri kwemakungwa, inotarisana nematambudziko akawanda: padivi rekuda, inmarsat network coverage yatove yakanaka kwazvo uye data inogona kufambiswa munzira mbiri, saka haina kusimba;Panyaya yekushandiswa, China ichiri kushomeka, kunyanya yakatarisana nemapurojekiti emidziyo.Nekuda kwezvikonzero zviri pamusoro, zvakaoma kumabhizinesi epamba setiraiti kusimudzira kushandiswa kweLR-FHSS.Panyaya yemari, mapurojekiti emhando iyi anonyanya kutsamira pakuiswa kwemari nekuda kwekusagadzikana kukuru, mapurojekiti makuru kana madiki uye marefu akareba.
