Emhlabeni wokuxhumana kwe-IoT, ubuchwepheshe be-LoRa buye bashintsha ukuxhumana okude, okunamandla aphansi. Manje, u-Semtech wethula uhlelo LR2021, i-transceiver yokuqala yomugqa omusha I-LoRa Plus, esethula ukuthuthukiswa okuphawulekayo kububanzi, isivinini sokudlulisela, nokuhambisana namanethiwekhi amaningi angenawaya namaphrothokholi.
Ngokwakhiwa okuthuthukisiwe nokusekelwa kwamanethiwekhi asemhlabeni nawesathelayithi, le chip ivela njengesixazululo esibalulekile sezinhlelo zokusebenza ezithuthukisiwe ze-IoT. Ngezansi, sihlola izici zayo nezinzuzo ngokuningiliziwe.
Imifanekiso ye-Semtech LR2021
El LR2021 Akukhona nje ukuvela kobuchwepheshe be-LoRa, kodwa ukweqa okubalulekile mayelana nokusebenza nokuhambisana. Lezi yizicaciso ezifanele kakhulu:
- Ukuhambisana namanethiwekhi asemhlabeni nawesathelayithi (NTN), asebenza ku i-sub-GHz, 2.4 GHz ISM ne-S-band enelayisensi.
- Ihambisana namadivayisi we-LoRa wangaphambilini, iqinisekisa a uguquko olubushelelezi kubakhiqizi.
- Kuhlanganisa ukusekelwa kwezinguquko ezihlukahlukene ezifana FLRC (kufika ku-2.6 Mbps), LoRa (kufika ku-200 kbps), FSK, OOK, O-QPSK kanye ne-LR-FHSS.
- Izakhiwo eziklanyelwe ukunciphisa izindleko zezinto (BOM), indawo ye-PCB nokusetshenziswa kwamandla.
Usekelo lwamaphrothokholi amaningi angenantambo
Elinye lamaphuzu athakazelisa kakhulu we-LR2021 ukuhambisana kwayo nezinhlobonhlobo ze amaphrothokholi angenawaya anamandla aphansi. Phakathi kwazo kukhona:
- Umgwaqo wase-Amazon: Isetshenziswa kumadivayisi e-Smart Home namanethiwekhi omphakathi.
- I-Meshtastic: Ilungele amanethiwekhi okuxhumana ahlukaniselwe amazwe.
- I-Wireless M-Bus (W-MBUS) ne-Wi-SUN FSK: Igxile ezinhlelweni zokusebenza zemitha ezihlakaniphile namanethiwekhi ezimboni.
- I-Z-Wave: Isetshenziswa ku-automation yasekhaya.
Ukusebenza okuthuthukisiwe nokusebenza kahle kwamandla
El LR2021 yethula ukuthuthuka okubalulekile ku ukusebenza kahle kwamandla kanye nokusebenza kokudlulisela. Ngenxa yomklamo wayo othuthukisiwe, inikeza:
- Ibanga lamandla okudlulisela elilungisekayo phakathi +22 dBm kanye -10 dBm.
- Ukuzwela okuthuthukisiwe okufika ku- -142 dBm ku-LoRa SF12/125 kHz, okuvumela ukuxhumana kwebanga elide ngokuphazamiseka okuncane.
- Ukusetshenziswa kwamandla ekwamukelweni kwe-nje 5.5 ma, okunweba impilo yamadivayisi asebenza ngebhethri.
Izicelo ze-Semtech LR2021
Ngenxa yokuguquguquka kwayo nokusebenza okuphezulu, le transceiver inika amandla amathuba amasha ezinhlelweni ezahlukahlukene:
- Ukuphepha nokuqapha: Isetshenziswa ekudutshulweni kwesibhamu kanye nezinzwa zokubona ukuphuka kwengilazi.
- Imizi ehlakaniphile: Izicelo ezinjengokuqapha kwethrafikhi nezinhlelo zokupaka.
- Impilo & Ukuphila Kahle: Ukuqaliswa kumadivayisi we ukutholwa kokuwa kanye nokuqapha isiguli.
- Imboni kanye namaGridi ahlakaniphile: Ilungele ukudluliswa kwedatha kumandla namanethiwekhi ezishintshayo zezimboni.
Ukutholakala nentuthuko yesikhathi esizayo
USemtech umemezele ukuthi i LR2021 izotholakala ukuthi ihlolwe ngaphakathi Ephreli 2025. Labo abanentshisekelo bangafunda okwengeziwe ngale transceiver emicimbini yomkhakha efana Umhlaba Oshumekiwe eJalimane futhi I-DistribuTECH e-United States
Ukwethulwa kwe-LR2021 kuqinisa ubuholi bukaSemtech ekuthuthukisweni kokuxhumana kwe-IoT. Okwakhe ukwesekwa kwamaphrothokholi amaningi, ukusebenza kahle kwamandla y ukusebenza okuphezulu okwenza kube yisixazululo esibalulekile sekusasa lezokuxhumana okungenantambo. Ukuze uthole ukwaziswa okwengeziwe mayelana nendlela yokukhetha amadivaysi afanelekile, ungabheka lesi sihloko Ungawakhetha kanjani amaphrinta we-3D.
