Ngā Tikanga Whakarea i roto i te Whakawhitiwhiti Kōrero
Pendahuluan
I te ao whakawhitiwhiti kōrero, he mea nui te whai huatanga me te whaihua o te tuku raraunga. Ko tētahi tikanga kua whakamātauhia he tino whai hua ki te whakanui ake i te kaha whatunga me te whakanui ake i te whakamahinga o ngā rauemi o nāianei ko te multiplexing. Ko te multiplexing he tikanga e taea ai te tuku i ngā tohu maha, i ngā awa raraunga rānei i te wā kotahi i runga i te ara tuku kotahi. Ka matapakihia e tēnei tuhinga ngā tikanga multiplexing e whakamahia ana i roto i ngā whakawhitiwhiti kōrero, mai i ngā mea taketake ki ngā mea matatau ake.
1. Te Mārama ki te Whakarea-maha
Ko te whakarea-maha he tikanga e whakakotahihia ai ngā awa raraunga e rua, neke atu rānei, hei awa kotahi hei tuku mā te reo whakawhitiwhiti kōrero. Kia tae atu ngā tohu ki tō rātou ūnga, ka wehea anō mā te whakamahi i ngā tikanga whakarea-maha. Mā tēnei, ka pai ake te whakamahi i ngā raina tuku me te whakaiti i te utu mā te whakarea-maha.
2. Ngā momo whakarea
He maha ngā tikanga whakarea e whakamahia whānuitia ana i roto i ngā whakawhitiwhiti kōrero, arā:
a. Te Whakareatanga Auau (FDM)
Ko te FDM te tikanga whakarea māmā rawa. I roto i te FDM, ka wehea te whānuitanga auau ki ētahi roopu auau iti ake, ka whakamahia ia roopu hei tuku raraunga takitahi. Ka tukuna ia rerenga raraunga i runga i tētahi auau kawe rerekē, kia taea ai te tuku i ngā rerenga raraunga maha i te wā kotahi me te kore e taupatupatu.
Ko te painga o te FDM he māmā noa iho, he ngāwari hoki te whakatinana. Heoi, ko te ngoikoretanga ko te iti o te awhe auau e wātea ana, ā, ka whakawhāitihia te maha o ngā rerenga raraunga ka taea te tuku i te wā kotahi.
b. Te Whakareatanga Wehenga Wā (TDM)
Ka mahi te TDM mā te wehewehe i te wā ki ngā wā motuhake. Ka hoatu ia wā ki tētahi awa raraunga kotahi hei tuku i ana mōhiohio. Kia mutu te wā, ka hoatu te huringa o te awa raraunga e whai ake nei. Ka taea e te TDM te whakamahi i te ara tuku kotahi i te wā kotahi, kia pai ake ai te whai huatanga o te ara tuku.
Ko te painga o te TDM ko tōna kaha ki te tuku raraunga me te kore e whakararuraru i ētahi atu rerenga raraunga. Heoi, he wero nui te tukutahitanga wā i roto i te whakatinanatanga o te TDM.
c. Te Whakareatanga Wehenga Roangaru (WDM)
Ko te WDM he momo rerekē o te FDM e whakamahia ana i roto i te tuku whatu, pērā i te muka whatu. I roto i te WDM, ka whakamahia te mārama o ngā roangaru rerekē hei tuku i ngā mōhiohio rerekē. Ka tukuna ngā awa raraunga rerekē i ngā roangaru rerekē o te mārama, ka taea ai te whakamahi i tētahi ara muka whatu kotahi mō ngā awa raraunga maha.
Ko te painga o te WDM he whakanui ake i te kaha o te muka whatu me te tautoko i ngā whakawhitiwhiti tere-teitei. He maha ngā wā ka whakamahia te WDM i roto i ngā whatunga whakawhitiwhiti kōrero hou hei tuku raraunga kaha-teitei i ngā tawhiti roa.
d. Te Whakareatanga Waehere (CDM)
Ko te CDM, e mōhiotia whānuitia ana ko te Code Division Multiple Access (CDMA), he tikanga whakarea e whakarerekētia ai ngā awa raraunga maha ki ngā waehere ahurei, kātahi ka tukuna mā te roopu auau kotahi. Ka whakamahia e ia taputapu whiwhi he waehere ōrite hei tango i ngā raraunga e hiahiatia ana mai i ngā tohu kua whakakotahihia.
Ko ngā painga o te CDM ko tōna ngāwari ki te whakamahi i te whānuitanga auau me tōna kaha ki te whakahaere i ngā pokanoa. He maha te whakamahinga o te CDM i roto i ngā whakawhitiwhitinga waea pūkoro nā te mea ka taea e ia te whakaputa i ngā whakawhitiwhitinga maha i runga i te auau kotahi me te kore he pokanoa nui.
3. Ngā Painga me ngā Wero
He maha ngā painga o ngā tikanga whakarea i roto i ngā whakawhitiwhiti kōrero, tae atu ki:
a. Te Whai Hua o te Whānuitanga: Mā te whakamahi i te maha o ngā auautanga ka whai hua ake te whakamahinga o te whāititanga auau iti, kia maha atu ai ngā awa raraunga ka taea te tuku mā te ara kotahi.
b. Te Whakaiti Utu: Mā te whakamahi i tētahi ara tuku kotahi mō ngā awa raraunga maha, ka taea te whakaiti nui i ngā utu hanganga.
c. Tauine: Mā te whakamahi i te maha o ngā whatunga whakawhitiwhiti kōrero ka taea te whakahaere i te piki haere o te maha o ngā kaiwhakamahi me ngā rerenga raraunga, me te kore e hiahiatia he hanganga ā-tinana nui atu.
Heoi anō, he maha ngā wero me wikitoria i te whakatinanatanga o te multiplexing, pēnei i:
a. Te Whakararuraru: I roto i ētahi tikanga whakarea pērā i te FDM me te WDM, ka raru pea te whakararuraru i waenga i ngā awa raraunga tata.
b. Tukutahitanga: I roto i te TDM, me whakarite kia tika te wā e whiwhi ai ia rerenga raraunga.
c. Te Whakakorenga Tukutahi: I roto i te CDM, ka puta pea te wetewete hē mēnā he hē te waehere, ka kore e taea te pānui i ngā raraunga.
4. Ngā Taupānga Whakarea i roto i ngā Whakawhitiwhiti Kōrero Hou
I roto i ngā whakawhitiwhiti kōrero o ēnei rā, he mea nui te mahi a te multiplexing i roto i te whānuitanga o ngā tono. Anei ētahi tauira:
a. Whatunga Pūkoro: E whakamahia whānuitia ana te tikanga CDM, CDMA rānei i roto i ngā whatunga pūkoro o te whakatupuranga tuatoru (3G) me ngā whatunga pūkoro o muri mai. Mā tēnei hangarau ka taea e ngā kaiwhakamahi maha te uru atu ki te whatunga pūkoro mā te whakamahi i te roopu auau kotahi, me te kore e pokanoa tetahi ki tetahi.
b. Whatunga muka whatu: Ka whakamahia te WDM i roto i ngā whatunga muka whatu hei whakanui ake i te kaha tuku. Ka whakamahia ngā roangaru rerekē hei tuku i ngā awa raraunga maha i te wā kotahi mā te taura muka whatu kotahi.
c. Ngā Whatunga Whakawhitiwhiti Kōrero Amiorangi: He maha ngā wā ka whakamahia te FDM me te TDM i roto i ngā whakawhitiwhiti kōrero amiorangi hei tohatoha i te whānui o te hononga e wātea ana i waenga i ngā kaiwhakamahi maha, i ngā awa raraunga rānei.
d. Whatunga Ipurangi: I roto i ngā whatunga ipurangi, ka whakamahia te multiplexing i ngā taumata rerekē, mai i te tohatoha i te whānui o te hononga i waenga i ngā kaiwhakamahi ki te tohatoha i ngā ara tuku i waenga i ngā tūmau me ngā pokapū raraunga.
Whakamutunga
He tikanga nui te whakarea-maha i roto i ngā whakawhitiwhiti kōrero hou, e āhei ai te whakamahi pai ake i ngā rauemi whatunga. Mā te whakamahi i ngā tikanga maha pēnei i te FDM, TDM, WDM, me te CDM, ka taea e te whakarea-maha te whakatutuki i ngā hiahia tuku raraunga e piki haere tonu ana o te whānuitanga o ngā tono whakawhitiwhiti kōrero. Ahakoa he maha ngā wero hangarau e pāngia ana, kei te haere tonu ngā whanaketanga hangarau ki te āhei i te whakarea-maha kia piki haere te whai hua me te pono, e tautoko ana i ngā whakawhitiwhiti kōrero tere ake me te pono ake puta noa i te ao.
