I. Uhlolojikelele Lwesistimu
Isistimu yokufunda imitha ye-HAC-MLW (LoRaWAN) isekelwe kubuchwepheshe be-LoraWAN, futhi iyisixazululo esiphelele sezinhlelo zokusebenza zokufunda amamitha akude ezihlakaniphile ezinamandla aphansi.Uhlelo luqukethe inkundla yokulawula ukufundwa kwamamitha, isango kanye nemojula yokufunda imitha.Uhlelo luhlanganisa ukuqoqwa kwedatha, ukulinganisa, ukuxhumana kwezindlela ezimbili, ukufundwa kwamamitha kanye nokulawulwa kwamavalvu, okuhambisana nephrothokholi evamile ye-LORAWAN1.0.2 eyakhiwe yi-LoRa Alliance.Kuyibanga elide lokudlulisela, ukusetshenziswa kwamandla okuphansi, usayizi omncane, ukuphepha okuphezulu, ukuthunyelwa okulula, ukunwetshwa okulula, ukufakwa okulula nokugcinwa.
II.Izingxenye Zesistimu
I-HAC-MLW (LoRaWAN) isistimu yokufunda imitha ekude engenantambo ihlanganisa: imojula yokufunda imitha engenantambo i-HAC-MLW, i-LoRaWAN Gateway, isistimu yokushaja imitha ye-LoRaWAN (I-Cloud Platform).
● Imojula yokufunda imitha engenantambo ye-HAC-MLW enamandla aphansi: Ithumela idatha kanye ngosuku, ihlanganisa ukutholwa kwedatha, imitha, ukulawula amavalvu, ukuxhumana okungenantambo, iwashi elithambile, ukusetshenziswa kwamandla okuphansi, ukuphathwa kwamandla kanye ne-alamu yokuhlasela kazibuthe kumojula eyodwa.
● Isango le-HAC-GWW: Isekela i-EU868, i-US915, i-AS923, i-AU915Mhz, i-IN865MHz, i-CN470 namanye amabhendi amafrikhwensi, isekela uxhumano lwe-Ethernet nokuxhumeka kwe-2G/4G, futhi isango elilodwa lingafinyelela kumatheminali angu-5000.
● Inkundla yokushaja yokufunda imitha ye-iHAC-MLW: Ingafakwa kunkundla yefu, inkundla inemisebenzi enamandla, futhi idatha enkulu ingasetshenziselwa ukuhlaziya ukuvuza.

IV.Izici Zesistimu
Ibanga elide kakhulu: Indawo yasemadolobheni: 3-5km, Indawo yasemaphandleni: 10-15km
Ukusetshenziswa kwamandla aphansi kakhulu: Imojula yokufunda imitha isebenzisa ibhethri le-ER18505, futhi ingafinyelela iminyaka eyi-10.
Ikhono eliqinile lokulwa nokuphazamiseka: Ukusebenza kwenethiwekhi okuzinzile, ukumbozwa okubanzi, ubuchwepheshe be-spectrum yokusabalalisa, ukulwa nokuphazanyiswa okuqinile.
Umthamo omkhulu: Inethiwekhi enkulu, isango elilodwa lingathwala amamitha angu-5,000.
Izinga eliphezulu lempumelelo yokufunda imitha: Inethiwekhi yenkanyezi, elungele ukunethiwekha futhi kulula ukuyilungisa.
Ⅴ.Isicelo Scenario
Ukufundwa kwamamitha angenantambo wamamitha amanzi, amamitha kagesi, amamitha egesi, namamitha okushisa.
Umthamo wokwakha esizeni ophansi, izindleko eziphansi kanye nezindleko eziphansi zokuqalisa ukusebenza.
