Haina -139dbm te kaiwhiwhi teitei te aro ki te tuku raraunga whakauru LoRa DTU mo te wheketere me ngā kaihanga

-139dbm te aro nui o te kaiwhiwhi ki te tuku raraunga whakauru i te kōwae LoRa DTU

Whakaahuatanga Poto:

Ko te pūrua whakauru LORA DTU module_MDL210 te mea e whakamahi ana i te hangarau horapa LoRa mō te tuku raraunga ahokore, e whakarato ana i tētahi aratau tuku raraunga mārama katoa, kāore he kawa. Me whakatakoto noa e koe ētahi tawhā māmā hei whakatutuki i ngā momo whatunga maha pēnei i te whatunga whetu me te whatunga Mata. He maha anō hoki ngā momo whakawhitiwhiti kōrero pēnei i te tono-ā-ringa, te pāho, me te maha-pāho i roto i te whatunga kotahi;
E whakaratohia ana te atanga whakawhitiwhiti TTL, he ngāwari ki te whakamahi mō ngā taputapu whatunga tauranga raupapa ahumahi, ā, he whānuitia te hoahoa iti-whakamahinga hiko e whakamahia ana e te puna hiko taputapu (≤40uA@5V).

-139dbm te tuku raraunga aro nui ki te kaiwhiwhitāmauKōwae LoRa DTU

E whakaratohia ana te atanga whakawhitiwhiti TTL, he ngāwari ki te whakamahi mō ngā taputapu whatunga tauranga raupapa ahumahi, ā, he whānuitia te hoahoa iti-whakamahinga hiko e whakamahia ana e te puna hiko taputapu (≤40uA@5V).

He tino teitei te aro o te hangarau LoRa ki te whiwhinga (RSSI) ā,

te tohu-ki-haruru nui (SNR) me tā mātou hangarau tautoko modem motuhake me te mahi hua pumau me te pono.

He tino kaha te āheinga ā-aukati-pokanoa o te waeine ahokore LoRa.

Ka mahi tahi a MDL210 me te 4G DTU a tā mātou kamupene, ka taea te whakahaere i te whakatūnga o te keti LoRa hei whakatutuki i te tuku raraunga mamao.

Whakawhitiwhiti kōrero pāho

I raro i te whatunga kotahi, ka whakawhitiwhiti kōrero ia taputapu ki a rātou anō

Whakawhitiwhiti kōrero ira-ira

I raro i te whatunga kotahi, ka whakamahia te whakawhitiwhiti kōrero i waenganui i ngā pūwāhi me ngā pūwāhi

ka taea te whakarite i waenganui i ngā taputapu e rua

Whakawhitiwhiti kōrero maha-whakaputa

I raro i te whatunga kotahi, ka taea te whakarite i ngā taputapu kotahi, maha rānei hei rōpū hei whakatutuki i te whakawhitiwhiti kōrero rōpū-ki-rōpū.

Ka taea te whakakotahi i ngā tikanga whatunga e toru o runga ake nei ki te whatunga kotahi

Haunga te whakamahi i te taura rangatū ā-rohe hei whirihora tika i ngā tawhā o te pūrere MIND LoRa,ka tautoko hoki i te ahokorete whirihora i ngā tawhā o te pūrere mamao.

E whakaaturia ana i te Pikitia:

Ka honoa te taputapu A ki te rorohiko mā te taura raupapa, ā, ka taea te whakamahi i te pūmanawa whirihoranga whakairoiro e whakaratohia ana e tā mātou kamupene hei whirihora i ngā tawhā o te taputapu ā-rohe A me te watea me te tere, ā, ka taea hoki te whirihora ahokore i ngā tawhā o te taputapu mamao B.

*Hei whirihora i ngā tawhā i te aratau ahokore, kia mohio kei roto te pūrere ā-rohe me te pūrere mamao i te whatunga kotahi

Mai i te tau 2015, kua tīmata tā mātou kamupene ki te whakawhanake me te whakaputa i ngā hua raupapa LoRa, me te tukunga katoa o neke atu i te 5,000 waeine. I roto i ngā tau e rua kua pahure ake nei, kua angitu te whakamahi i ngā hua raupapa LoRa ki te kaupapa "Whakatūpato Mōrearea Waipuke Maunga ā-Motu" i uru atu ai tā mātou kamupene. Kua whakaatuhia e ngā meka kua mōhiotia ā mātou hua i roto i te umanga, ā, he pai te ingoa o ā mātou kaihoko.
