Ukuhlaziywa kokusetshenziswa nokwabiwa kwebhendi yemvamisa ye-1250MHz

Ibhendi yemvamisa engu-1250MHz ithatha indawo ebalulekile ku-spectrum yomsakazo futhi isetshenziswa kabanzi emikhakheni efana nokuxhumana ngesathelayithi kanye nezinhlelo zokuzulazula. Ibanga layo elide lokudlulisa isignali kanye nokuncipha okuphansi kuyinika izinzuzo ezihlukile ezinhlelweni ezithile.

Izindawo eziyinhloko zohlelo lokusebenza:

Ukuxhumana ngesathelayithi: Ibhendi yemvamisa engu-1250MHz isetshenziswa kakhulu ekuxhumaneni phakathi kwamasathelayithi neziteshi zomhlaba. Le ndlela yokuxhumana ingafinyelela ukumbozwa kwendawo ebanzi, inezinzuzo zebanga elide lokudlulisa isignali kanye nekhono eliqinile lokuvimbela ukuphazamiseka, futhi isetshenziswa kabanzi emikhakheni efana nokusakaza kuthelevishini, ukuxhumana ngeselula kanye nokusakaza ngesathelayithi.

Uhlelo lokuzulazula: Kubhendi yemvamisa engu-1250MHz, ibhendi yemvamisa ye-L2 ye-Global Satellite Positioning System (GNSS) isebenzisa le mvamisa ukuze ibeke kahle futhi ilandelele. I-GNSS isetshenziswa kabanzi kwezokuthutha, ezindiza, ekuzulazuleni kwemikhumbi kanye nasekuhloleni i-geological.

Isimo samanje sokwabiwa kwe-spectrum:

Ngokusho kwe-“Radio Frequency Allocation Regulations of the People's Republic of China”, izwe lami lenze izigaba ezinemininingwane zamafrikhwensi omsakazo ukuze kuhlangatshezwane nezidingo zamabhizinisi ahlukene.

Kodwa-ke, ulwazi oluthile lokwabiwa kwebhendi yemvamisa ye-1250MHz alunazo imininingwane eningiliziwe emphakathini.

I-International spectrum allocation dynamics: Ukwabiwa kwe-spectrum yamazwe ngamazwe:

NgoMashi 2024, amaSeneta ase-US aphakamisa uMthetho Wepayipi Le-Spectrum ka-2024, ephakamisa ukuthi kudayiswe amanye amabhendi emvamisa aphakathi kuka-1.3GHz no-13.2GHz, okwenza isamba sezinsiza ze-spectrum sibe ngu-1250MHz, ukuze kuthuthukiswe intuthuko yamanethiwekhi e-5G ezentengiselwano.

Umbono Wesikhathi Esizayo:

Ngokuthuthuka okusheshayo kobuchwepheshe bokuxhumana obungenantambo, isidingo sezinsizakusebenza ze-spectrum siyakhula. Ohulumeni nezinhlangano ezifanele balungisa ngenkuthalo amasu okwabiwa kwe-spectrum ukuze bahlangabezane nezidingo zobuchwepheshe nezinsizakalo ezisafufusa. Njenge-spectrum ye-mid-band, i-band ye-1250MHz inezici ezinhle zokusabalala futhi ingasetshenziswa emikhakheni eminingi esikhathini esizayo.

Ngamafuphi, ibhendi ye-1250MHz okwamanje isetshenziswa kakhulu ezinhlelweni zokuxhumana zesathelayithi kanye nokuzulazula. Ngokuthuthuka kobuchwepheshe kanye nokulungiswa kwezinqubomgomo zokuphathwa kwe-spectrum, ububanzi bokusetshenziswa kwaleli bhendi kulindeleke ukuthi bunwetshwe kabanzi.
