Yini uLoraWabani?

ILorawan i-Low Power Power Area Network (LPWAN) Ukucaciswa okwenzelwe i-wireless, amadivayisi asebenza ngebhethri. ULora usevele edluliselwe ezigidini zezinzwa, ngokusho kweLora-Alliance. Ezinye zezinto eziphambili ezisebenza njengoba isisekelo sezincazelo zingukuxhumana okuqondiswayo, ukuhambisa kanye nezinsizakalo zokwenziwa kwasendaweni.

Indawo eyodwa lapho i-lorawan ihluke khona kwezinye izinhlobo zenethiwekhi ukuthi isebenzisa i-Star Architecture, inendawo ephakathi kuyo yonke indawo exhunywe kuyo futhi ama-Gateways asebenza njengemiyalezo ebonakalayo edlulisa imiyalezo phakathi kwamadivayisi ama-End. Amasango axhunyiwe kwiseva yenethiwekhi ngokuxhumeka okujwayelekile kwe-IP ngenkathi amadivaysi okuphela asebenzisa ukuxhumana okungenantambo kwe-hop eyodwa kuya kwisango elilodwa noma amaningi. Ukuxhumana kwe-End-Point kuyinto eqondiswa yi-BI-DRETAAL, futhi kusekela i-multicast, ukuvumelanisa izibuyekezo zesoftware emoyeni. Ngokusho kweLora-Alliance, inhlangano engenzi nzuzo eyadala ukucaciswa kweLorawan, lokhu kusiza ekugcinweni kwempilo yebhethri futhi kufinyelele ukuxhumana okude.

Isango elilodwa elinikeziwe le-LORA elinikwe amandla noma isiteshi se-Base lingamboza wonke amadolobha noma amakhulukhulu amakhilomitha skwele. Vele, ibanga lincike emvelweni yendawo enikeziwe, kepha uLora noLorawan bathi banesabelomali sesixhumanisi, into eyinhloko ekunqumeni uhla lwezokuxhumana, enkulu kunanoma yibuphi ubuchwepheshe bokuxhumana obekiwe.

Amakilasi we-End-Point

ILorawan inezigaba eziningana ezahlukahlukene zamadivayisi we-End-Point ukubhekana nezidingo ezihlukile eziboniswe ezinhlobonhlobo zezicelo. Ngokwewebhusayithi yayo, lokhu kufaka phakathi:

• Amadivayisi we-Bi-Direct And (Class a): Amadivayisi ama-End I-Slot Slot ehlelelwe i-End-device isuselwa kwizidingo zayo zokuxhumana ngokuhlukahluka okuncane ngokususelwa ngesikhathi esingahleliwe (i-Aloha-TYPE YOTOTOLOL). Lesi sigaba A Ukusebenza kunguhlelo lwedivaysi ephansi kakhulu yamandla okusebenza kwezicelo ezidinga kuphela ukuxhumana kwe-DownLink kusuka kuseva ngemuva nje kokuthumela ukuhanjiswa kwe-uplink. Ukuxhumana okwenziwe phansi kweseva kunoma yisiphi esinye isikhathi kuzodingeka ukuthi ulinde kuze kube yilapho uplink elandelayo ehleliwe.
• Amadivayisi we-Bi-Direct End nge-Slots ehleliwe (Class B): Ngokungeziwe ekilasini A Okungahleliwe Thola ama-Windows, Class B Amadivayisi Vula Okungeziwe Thola amawindi ngezikhathi ezihleliwe. Ukuze i-END-divayda ukuvula iwindi layo le-Thola ngesikhathi esinqunyelwe ithola isikhathi esivumelanisiwe esivumelanisiwe esivela esangweni. Lokhu kuvumela ukuthi iseva yazi ukuthi idivaysi yokugcina ilalela nini.
• Amadivayisi we-Bi-Directleal With maximal athola slots (Class C): Amadivayisi ama-End-Class C acishe avule ngokuqhubekayo Thola amawindi, avale kuphela lapho edlulisa.
