PutumōhioKo te C-band, he awhe auau reo irirangi kei waenganui i te 3.4 GHz me te 4.2 GHz, he mea nui ki ngā whatunga 5G. Nā ōna āhuatanga ahurei i whai wāhi nui ai ki te whakatutuki i ngā ratonga 5G tere-teitei, iti-roa, me te whānui o te kapinga.
1. Te taurite o te kapinga me te tere tuku
Kei roto te roopu-C i te whānuitanga waenga-roopu, ka taea e tēnei te whakarato i te taurite pai i waenga i te kapinga me te tere tuku raraunga. Ki te whakatauritea ki te roopu-iti, ka taea e te roopu-C te whakarato i ngā tere tuku raraunga teitei ake; ā, ki te whakatauritea ki ngā roopu auau-teitei (pērā i ngā ngaru mirimita), he whānui ake te kapinga o te roopu-C. Nā tēnei taurite ka tino pai te roopu-C mō te whakatinana i ngā whatunga 5G i roto i ngā taiao tāone me ngā taiao tāone iti, kia whakarite ai ka whiwhi ngā kaiwhakamahi i ngā hononga tere-teitei me te whakaiti i te maha o ngā teihana turanga kua whakatinanahia.
2. Ngā rauemi whānuitanga nui
Ka whakaratohia e te C-band he whānuitanga o te whānuitanga o te whānuitanga hei tautoko i te kaha raraunga nui ake. Hei tauira, i tohaina e te Federal Communications Commission (FCC) o te Hononga o Amerika he 280 MHz o te whānuitanga waenga-roopu mō te 5G i roto i te C-band, ā, i hokona i te mutunga o te tau 2020. I whiwhi ngā kaiwhakahaere pēnei i a Verizon me AT&T i te nui o ngā rauemi whānuitanga i roto i tēnei hokohoko, ā, i whakarato i te turanga pakari mō ā rātou ratonga 5G.
3. Tautoko i te hangarau 5G matatau
Mā ngā āhuatanga auau o te C-band ka taea e ia te tautoko pai i ngā hangarau matua i roto i ngā whatunga 5G, pērā i te MIMO nui (whakauru maha-putanga maha) me te hanga hihi. Ka taea e ēnei hangarau te whakapai ake i te whai huatanga o te whānuitanga, te whakarei ake i te kaha whatunga, me te whakapai ake i te wheako kaiwhakamahi. Hei tāpiri, mā te painga o te whānui o te C-band ka taea e ia te whakatutuki i ngā whakaritenga tere-teitei me te iti-roa o ngā tono 5G a meake nei, pērā i te mooni whakanuia (AR), te mooni mariko (VR), me te Ipurangi o ngā Mea (IoT).
4. Whānui te whakamahinga puta noa i te ao
He maha ngā whenua me ngā rohe kua whakamahi i te C-band hei roopu auau matua mō ngā whatunga 5G. Hei tauira, ko te nuinga o ngā whenua i Ūropi me Āhia e whakamahi ana i te roopu n78 (3.3 ki te 3.8 GHz), ko te United States ia e whakamahi ana i te roopu n77 (3.3 ki te 4.2 GHz). Mā tēnei āhua ōrite o te ao ka hangaia he pūnaha 5G kotahi, ka whakatairanga i te hototahitanga o ngā taputapu me ngā hangarau, ka tere ake te rongonui me te tono o te 5G.
5. Whakatairanga i te whakatinanatanga arumoni 5G
Nā te whakamahere mārama me te tohatoha o te whānuitanga C-band i tere ake ai te whakatinanatanga arumoni o ngā whatunga 5G. I Haina, kua tohua mārama e te Manatū Ahumahi me te Hangarau Mōhiohio ko ngā roopu 3300-3400 MHz (te whakamahinga o roto i te kaupapa matua), 3400-3600 MHz me te 4800-5000 MHz hei roopu whakahaere o ngā pūnaha 5G. Mā tēnei whakamahere ka whakaratohia he aronga mārama mō te rangahau me te whanaketanga me te hokohoko o ngā taputapu pūnaha, ngā maramara, ngā pūrua me ngā taputapu whakamātautau, ā, ka whakatairanga i te hokohoko o te 5G.
Hei whakarāpopototanga, he mahi nui tā te C-band i roto i ngā whatunga 5G. Nā ōna painga ki te kapinga, te tere tuku, ngā rauemi whānuitanga me te tautoko hangarau, he tūāpapa nui tēnei mō te whakatutuki i te tirohanga 5G. I te whanaketanga haere o te whakatinanatanga o te 5G ā-ao, ka nui haere te hiranga o te mahi a te C-band, ka pai ake ai te wheako whakawhitiwhiti kōrero a ngā kaiwhakamahi.
