Whakaahuatanga Poto:

Ko te tauranga whakauru LORA DTU module_MDL210 te mea e whakamahi ana i te hangarau hihinga horahanga a LoRa mo te tuku raraunga ahokore, e whakarato ana ki nga kaiwhakamahi te aratau tuku raraunga tino marama-kore kawa. Me whakarite e koe etahi tawhā ngawari noa hei whakatutuki i nga momo momo whatunga penei i te whatunga whetu me te whatunga Mesh. He maha ano nga momo whakawhitiwhiti korero penei i runga i te tono, i te haapurororaa, i te maha i roto i te whatunga kotahi;
Ka whakaratohia te atanga korero TTL , Ko te whatunga taputapu tauranga rangatū-kaimahi-kaiwhakamahi, te taputapu hiko taputapu e mau ana i te whānuitanga o te hoahoa iti te whakamahi hiko (≤40uA@5V).

-139dbm teitei te tuku raraunga whakaraeraetanga o te kaikawe kua whakauruhia ki te waahanga LoRa DTU

Ka whakaratohia te atanga korero TTL , Ko te whatunga taputapu tauranga rangatū-kaimahi-kaiwhakamahi, te taputapu hiko taputapu e mau ana i te whānuitanga o te hoahoa iti te whakamahi hiko (≤40uA@5V).

Hangarau LoRa ano he tino recei sensitivity (RSSI) me

tohu-ki-haruru nui (SNR) me ta maatau hangarau tautoko pouwhanga rangatira me te mahi hua e mau ana, pono hoki.

Ko te kōwae ahokore LoRa he tino kaha ki te aukati i te pokanoa.

Ka mahi tahi a MDL210 me te 4G DTU o ta matou kamupene, ka taea te whakatuu i te kuaha LoRa kia mohio ai te tuku raraunga mamao.

Whakawhitiwhiti korero

I raro i te whatunga kotahi, ka whakawhitiwhiti korero a ia taputapu ki a raatau ano

Tohu - Whakawhiti korero

I raro i te whatunga kotahi, te korero tohu-tohu

i waenganui i nga taputapu e rua ka taea te mohio

Te whakawhitiwhiti korero maha

I raro i te whatunga kotahi, ka taea te whakarite i nga taputapu kotahi, maha ranei hei roopu ki te mohio ki te whakawhitiwhitinga roopu-ki-rōpū

Ko nga tikanga whatunga e toru i runga ake nei ka taea te whakakotahi ki te whatunga kotahi

I tua atu i te whakamahi i te taura rangatū rohe ki te whirihora tika i nga tawhā o te taputapu MIND LoRa,tautoko ahokore ana hokiwhirihora i nga tawhā o te taputapu mamao.

Ka whakaatuhia i te FIG:

Ko te taputapu A e hono ana ki te rorohiko na roto i te taura rangatū, a ka taea te whakamahi i te rorohiko whirihoranga kauwhata e whakaratohia ana e to tatou kamupene ki te whirihora i nga tawhā o te taputapu A rohe i te waatea me te tere, ka taea hoki te whirihora i nga tawhā o te taputapu mamao B. ahokore.

*Ki te whirihora i nga tawhā i roto i te aratau ahokore, me whakarite kei roto i te whatunga kotahi te taputapu paetata me te taputapu mamao

Mai i te tau 2015, kua timata ta matou kamupene ki te whakawhanake me te whakaputa i nga hua raupapa LoRa, me te nui atu i te 5,000 nga waahanga tuku. I roto i nga tau e rua kua pahure ake nei, kua pai te tono o nga hua raupapa LoRa ki te kaupapa "National Mountain Flood Disaster Early Warning" i uru mai ta matou kamupene. Ko nga korero pono kua whakamatauhia e matou me tona kounga teitei, te pumau, me te tino taurangi. Ko nga ahuatanga, kua mohiotia ona hua i roto i te umanga me te whai ingoa pai ki waenga i nga kaihoko.
