Uhlalutyo lokusetyenziswa kunye nokwabiwa kwebhendi yefrikhwensi ye-1250MHz

Ibhendi yefrikhwensi ye-1250MHz ikwindawo ebalulekileyo kwi-spectrum yerediyo kwaye isetyenziswa kakhulu kwiindawo ezifana nonxibelelwano lwesathelayithi kunye neenkqubo zokuhamba. Umgama wayo wokudlulisa isignali ende kunye nokuncitshiswa okuphantsi kuyinika iingenelo ezikhethekileyo kwizicelo ezithile.

Iindawo eziphambili zesicelo:

Unxibelelwano lwesathelayithi: Ibhendi yesathelayithi ye-1250MHz isetyenziswa kakhulu kunxibelelwano phakathi kwesathelayithi kunye nezikhululo zomhlaba. Le ndlela yonxibelelwano inokufikelela kwindawo ebanzi, ineengenelo zomgama wokudlulisa isignali ende kunye nokukwazi okunamandla okulwa nokuphazamiseka, kwaye isetyenziswa kakhulu kwiindawo ezifana nokusasaza kumabonwakude, unxibelelwano oluphathwayo kunye nokusasaza ngesathelayithi.

Inkqubo yokukhangela: Kwibhendi yefrikhwensi ye-1250MHz, ibhendi yefrikhwensi ye-L2 yeNkqubo yokuPosa iSatellite yeHlabathi (i-GNSS) isebenzisa le frikhwensi ukuze ibeke indawo echanekileyo kunye nokulandelela. I-GNSS isetyenziswa kakhulu kwezothutho, kwi-aerospace, ekuhambeni ngeenqanawa nasekuhloleni i-geology.

Imeko yangoku yokwabiwa kwe-spectrum:

Ngokwe-“Radio Frequency Allocation Regulations of the People's Republic of China”, ilizwe lam lenze ulwahlulo oluneenkcukacha lwee-radio frequency ukuhlangabezana neemfuno zamashishini ahlukeneyo.

Nangona kunjalo, ulwazi oluthile lokwabiwa kwebhendi yefrikhwensi ye-1250MHz aluchazwanga kulwazi lukawonke-wonke.

Iintshukumo zokwabiwa kwe-spectrum yamazwe ngamazwe:

NgoMatshi 2024, iiSenator zase-US zacebisa uMthetho weMibhobho yeSpectrum ka-2024, zicebisa ukuthengiswa kwamanye amabhendi eefrikhwensi phakathi kwe-1.3GHz kunye ne-13.2GHz, ewonke afikelela kwi-1250MHz yezixhobo zespectrum, ukukhuthaza uphuhliso lweenethiwekhi zorhwebo ze-5G.

Imbono Yexesha Elizayo:

Ngenxa yophuhliso olukhawulezileyo lwetekhnoloji yonxibelelwano olungenazingcingo, imfuno yezixhobo ze-spectrum iyanda. Oorhulumente kunye nee-arhente ezifanelekileyo balungisa ngokukhutheleyo amaqhinga okwabiwa kwe-spectrum ukuhlangabezana neemfuno zobuchwepheshe kunye neenkonzo ezintsha. Njenge-spectrum ye-mid-band, i-1250MHz band ineempawu ezilungileyo zokusasaza kwaye ingasetyenziswa kwiindawo ezininzi kwixesha elizayo.

Ngamafutshane, ibhendi ye-1250MHz okwangoku isetyenziswa kakhulu kwiinkqubo zonxibelelwano lwesathelayithi kunye nokuhambisa. Ngophuhliso lwetekhnoloji kunye nokulungiswa kwemigaqo-nkqubo yolawulo lwe-spectrum, umda wokusetyenziswa kwale bhendi kulindeleke ukuba wandiswe ngakumbi.
