Ibhendi yefrikhwensi ye-1250MHz ithatha isikhundla esibalulekile ku-spectrum yomsakazo futhi isetshenziswa kakhulu emikhakheni efana nezokuxhumana ngesathelayithi nezinhlelo zokuhamba. Ibanga layo elide lokudlulisela isignali kanye nokuncipha okuphansi kuyinikeza izinzuzo eziyingqayizivele ezinhlelweni ezithile.
Izindawo zokufaka izicelo eziyinhloko:
Ukuxhumana ngesathelayithi: Ibhendi yefrikhwensi engu-1250MHz isetshenziselwa kakhulu ukuxhumana phakathi kwamasathelayithi neziteshi eziphansi. Le ndlela yokuxhumana ingafinyelela ukusabalala kwendawo ebanzi, inezinzuzo zebanga elide lokudluliswa kwesignali kanye nekhono eliqinile lokulwa nokuphazamiseka, futhi isetshenziswa kakhulu emikhakheni efana nokusakaza kumabonakude, ezokuxhumana ngomakhalekhukhwini kanye nokusakaza ngesathelayithi.
Isistimu yokuzulazula: Kubhendi yefrikhwensi engu-1250MHz, ibhendi yefrikhwensi ye-L2 ye-Global Satellite Positioning System (GNSS) isebenzisa le frikhwensi ukuze imise kahle futhi ilandele ngomkhondo. I-GNSS isetshenziswa kakhulu kwezokuthutha, i-aerospace, ukuhamba ngomkhumbi kanye nokuhlola umhlaba.
Isimo samanje sokwabiwa kwe-spectrum:
Ngokuvumelana ne “Radio Frequency Allocation Regulations of the People’s Republic of China”, izwe lami lenze izigaba ezinemininingwane zamaza omsakazo ukuze kuhlangatshezwane nezidingo zamabhizinisi ahlukene.
Kodwa-ke, imininingwane ethile yokwabiwa kwebhendi yefrikhwensi ye-1250MHz ayinikeziwe imininingwane yomphakathi.
Amandla okunikezwa kwe-spectrum yamazwe ngamazwe:
NgoMashi 2024, izigele zase-US zaphakamisa umthetho we-Spectrum Pipeline Act ka-2024, ehlongoza ukuthi kudayiswe amanye amabhendi amafrikhwensi phakathi kuka-1.3GHz no-13.2GHz, okuhlanganisa u-1250MHz wezinsiza ze-spectrum, ukukhuthaza ukuthuthukiswa kwamanethiwekhi ezentengiselwano e-5G.
I-Outlook Yesikhathi esizayo:
Ngokuthuthuka okusheshayo kobuchwepheshe bokuxhumana okungenantambo, isidingo sezinsiza ze-spectrum siyakhula. Ohulumeni nama-ejensi afanele balungisa ngokuzimisela amasu okwabiwa kwe-spectrum ukuze kuhlangatshezwane nezidingo zobuchwepheshe obusafufusa kanye nezinsizakalo. Njengesibukeli sebhendi emaphakathi, ibhendi ye-1250MHz inezici ezinhle zokusakaza futhi ingase isetshenziswe ezinkambini eziningi ngokuzayo.
Kafushane, ibhendi ye-1250MHz okwamanje isetshenziswa kakhulu kwezokuxhumana ngesathelayithi nezinhlelo zokuzulazula. Ngokuthuthukiswa kobuchwepheshe kanye nokulungiswa kwezinqubomgomo zokuphatha i-spectrum, ububanzi bokusebenza baleli bhendi kulindeleke ukuthi bunwetshwe futhi.
