Pūnaha haonamepūihi porowhita ruaE rua ngā momo pūihi e whakamahia ana i roto i ngā momo mara rerekē nā ō rātou āhuatanga me ā rātou mahi ahurei. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā āhuatanga o ngā pūihi haona me ngā pūihi takirua-polarized, ā, ka rukuhia hoki ngā momo whakamahinga e whakamahia whānuitia ai ēnei pūihi.
Ko te pūihi haona he pūihi ahunga e whakamahia whānuitia ana i roto i ngā pūnaha whakawhitiwhiti ngaruiti me te auau reo irirangi. He āhua kōniko, he āhua piramiti rānei ō rātou, e āhei ai rātou ki te tuku me te whiwhi i ngā ngaru hikohiko. Kua hangaia ngā pūihi haona kia whānui te whānui o te hononga me te whakanui teitei, kia pai ai mō ngā whakawhitiwhiti tawhiti me ngā pūnaha radar.
Ko te pūihi takirua-porowhita ia, he pūihi ka taea te tuku me te whiwhi i ngā ngaru reo irirangi i roto i ngā porowhita orthogonal e rua i te wā kotahi. Ko te tikanga ka taea e rātou te whakahaere i ngā porowhita whakapae me te poutū, ā, ka piki ake te kaha raraunga me te kounga tohu i roto i ngā pūnaha whakawhitiwhiti kōrero.
Ko tētahi o ngā wāhi tono matua mō ngā pūihi haona ko ngā pūnaha radar. Nā te nui o te pikinga me te aronga tika, e whakamahia whānuitia ana ngā pūihi haona i roto i ngā whakaurunga radar mō te whakahaere waka rererangi, te aroturuki i te huarere, me te tirotiro hōia. Nā te kaha ki te tuku me te whiwhi tika i ngā ngaru hikohiko i ngā tawhiti roa, he mea nui ēnei mō te hangarau radar.
Haunga ngā pūnaha radar, ka whakamahia hoki ngā pūihi haona i roto i ngā whakawhitiwhiti kōrero amiorangi. Nā te whānui o te whānui me te nui o te whiwhinga o ngā pūihi haona, he pai mō te tuku me te whiwhi tohu mai i ngā amiorangi i te wāhi. Ahakoa he pāpāho pouaka whakaata, he hononga ipurangi, he pūnaha tūnga ā-ao rānei, he mea nui te mahi a ngā pūihi haona ki te whakatū hononga whakawhitiwhiti kōrero pono ki ngā amiorangi.
Hei tāpiritanga, he whānuitia te whakamahinga o ngā pūihi haona i roto i ngā pūnaha whakawhitiwhiti ahokore pērā i ngā hononga ngaruiti-ki-te-pū me ngā whatunga rohe ahokore (WLAN). Nā tō rātou aronga tika me te nui o te whiwhinga ka pai ai mō te whakatū hononga ahokore tawhiti, inā koa i ngā tāone nui me ngā taiwhenua he mea nui te whakawhitiwhiti ahokore tirohanga-ā-rangi.

Mōngā pūihi takirua-polarized, e whakamahia ana i roto i ngā pūnaha whakawhitiwhiti ahokore e hiahia ana kia nui te rere o ngā raraunga me te pono o te tohu. Hei tauira, i roto i ngā whatunga pūkoro, ka whakamahia ngā pūihi takirua-polarized hei whakarei ake i te kaha me te mahi a ngā teihana turanga mā te tautoko i ngā whakaurunga maha-maha-putangahangarau (MIMO)Mā te tuku me te whiwhi tohu i roto i ngā porowhita orthogonal e rua, ka taea e ngā pūihi porowhita-rua te whakawhiti raraunga i te wā kotahi, ka whakapai ake i te whai huatanga o te hihi me te kapinga whatunga.
Hei tāpiritanga, he wāhanga nui ngā pūihi takirua-porowhita i roto i ngā mahi arorangi reo irirangi me ngā mahi tirotiro mamao. Ka taea e rātou te hopu i ngā ngaru reo irirangi porowhita whakapae me poutū, ka taea ai te kimi me te tātari tika i ngā āhuatanga o te rangi me te taiao. I roto i te arorangi reo irirangi, ka whakamahia ngā pūihi takirua-porowhita hei ako i ngā āhuatanga porowhita o ngā pūtake o te ao, ka whakarato i ngā māramatanga whai hua ki te āhua o ngā tinana o te rangi me te ao whānui.
I roto i te ao pāpāho ahokore, ka whakamahia ngā pūihi takirua-porowhita mō ngā tuku pouaka whakaata whenua me te reo irirangi. Mā te whakamahi i ngā pūihi takirua-porowhita, ka taea e ngā kaiwhakapāho te arotau i te whakamahinga o te whānuitanga reo irirangi me te whakapai ake i te kounga o ngā tohu pāpāho, kia pai ake ai te wheako oro-ataata mō ngā kaimātakitaki.

Hei whakarāpopototanga, he maha ngā whakamahinga o ngā pūihi haona me ngā pūihi takirua-porowhita i roto i ngā momo tono tae atu ki ngā pūnaha radar, ngā whakawhitiwhiti kōrero amiorangi, ngā whatunga ahokore, te whetū reo irirangi me te pāpāho. Nā ō rātou āhuatanga ahurei me ngā āheinga e tino hiahiatia ai mō te whakatū hononga whakawhitiwhiti kōrero pono me te whai hua me te whakatairanga i te rangahau pūtaiao me te auahatanga hangarau. I te mea kei te tipu haere tonu te hiahia mō ngā pūihi mahi-teitei, e matapaetia ana ka noho tonu te hiranga o ngā pūihi haona me ngā pūihi takirua-porowhita i roto i ngā whakawhitiwhiti kōrero hou me ngā mahi pūtaiao.
