Te Whakakotahi TETRA Wehewehenga Teitei mō te 380-470MHz
Ko te whakakotahi TETRA he taputapu RF e whakamahia ana i roto i ngā pūnaha TETRA (Terrestrial Trunked Radio) hei whakakotahi i ngā hongere tuku, whiwhi rānei maha ki runga i te pūihi kotahi, i te iti rānei o ngā tauranga pūihi. Mahi ⭐Ka whakakotahi i ngā tuku teihana turanga TETRA maha ki roto i te pūnaha pūihi kotahi...Pānuihia atu -
Ngā Kaitātari Whakawhitiwhitinga Paheko
I te pikinga ake o ngā tono mō ngā pūnaha whakawhitiwhiti waea pūkoro, kua noho ko te Passive Intermodulation (PIM) hei take nui. Ka taea e ngā tohu mana teitei i roto i ngā hongere tuku tiritahi te whakaatu i ngā āhuatanga kore-raina o ngā wāhanga raina tawhito pērā i ngā duplexers, ngā tātari, ngā antennas, me ngā hononga...Pānuihia atu -
Te tūranga o te pito mua o te RF i roto i ngā pūnaha whakawhitiwhiti kōrero
I roto i ngā pūnaha whakawhitiwhiti kōrero o ēnei rā, he mea nui te mahi a te pito mua o te Auautanga Reo Irirangi (RF) hei whakahohe i te whakawhitiwhiti kōrero ahokore whai hua. Kei waenganui i te pūihi me te papa matihiko, ko te pito mua o te RF te kawenga mō te tukatuka i ngā tohu e haere mai ana me ngā tohu e puta atu ana, ā, he mea nui tēnei hei whakawhitiwhiti kōrero...Pānuihia atu -
Ngā otinga matatau mō ngā pūnaha whakawhitiwhiti kōrero āwhati mō te haumaru tūmatanui
I roto i te ao o te haumaru tūmatanui, he mea nui ngā pūnaha whakawhitiwhiti kōrero ohorere hei pupuri i te whakawhitiwhiti kōrero i ngā wā ohorere. Ka whakauruhia e ēnei pūnaha ngā hangarau maha pēnei i ngā tūāpapa ohorere, ngā pūnaha whakawhitiwhiti kōrero amiorangi, ngā pūnaha ngaru poto me ngā pūnaha ngaru poto rawa, me te aroturuki i te pūoko mamao ...Pānuihia atu
