Ibhendi yefrikhwensi ye-1250MHz ikwindawo ebalulekileyo kwi-spectrum yerediyo kwaye isetyenziswa kakhulu kumabala anjengonxibelelwano lwesathelayithi kunye neenkqubo zokuhamba. Umgama wayo omde wokuhambisa umqondiso kunye nokunciphisa okuphantsi kukunika inzuzo ekhethekileyo kwizicelo ezithile.
Iindawo zesicelo eziphambili:
Unxibelelwano ngeSathelayithi: I-1250MHz frequency band isetyenziswa ikakhulu kunxibelelwano phakathi kwesathelayithi kunye nezikhululo eziphantsi. Le ndlela yokunxibelelana inokufikelela kwindawo ebanzi, ineengenelo zomgama omde wokuhanjiswa komqondiso kunye nobuchule obunamandla bokuchasana nokuphazamiseka, kwaye isetyenziswa kakhulu kwiinkalo ezifana nosasazo lukamabonakude, unxibelelwano ngeselula kunye nosasazo lwesathelayithi.
Inkqubo yokukhangela: Kwibhendi yefrikhwensi ye-1250MHz, ibhendi ye-L2 ye-Global Satellite Positioning System (GNSS) isebenzisa le frikhwensi yokubeka ngokuchanekileyo kunye nokulandela umkhondo. I-GNSS isetyenziswa kakhulu kwezothutho, kwi-aerospace, ukuhamba ngeenqanawa kunye nokuhlola umhlaba.
Imo yangoku yolwabiwo lwe-spectrum:
Ngokwe-“Radio Frequency Allocation Regulations of the People’s Republic of China”, ilizwe lam lenze izahlulo ezineenkcukacha zamaza kanomathotholo ukuhlangabezana neemfuno zamashishini awohlukeneyo.
Nangona kunjalo, ulwazi oluthile lolwabiwo lwe-1250MHz frequency band aluchazwanga kulwazi loluntu.
Amandla olwabiwo lwamazwe ngamazwe:
Ngo-Matshi ka-2024, iisenenja zase-US zaphakamisa uMthetho we-Spectrum Pipeline ka-2024, ecebisa ukuba kuthengiswe ezinye iibhendi zamaza phakathi kwe-1.3GHz kunye ne-13.2GHz, iyonke i-1250MHz yemithombo ye-spectrum, ukukhuthaza uphuhliso lothungelwano lwe-5G yorhwebo.
Ujongo lwekamva:
Ngophuhliso olukhawulezayo lwetekhnoloji yonxibelelwano engenazingcingo, imfuno yemithombo ye-spectrum iyakhula. Oorhulumente kunye nee-arhente ezifanelekileyo zilungelelanisa ngokusebenzayo izicwangciso zolwabiwo lwee-spectrum ukuhlangabezana neemfuno zeteknoloji kunye neenkonzo ezikhulayo. Njengomboniso webhendi ephakathi, ibhendi ye-1250MHz ineempawu ezilungileyo zokusasaza kwaye inokusetyenziswa kumasimi amaninzi kwixesha elizayo.
Isishwankathelo, ibhendi ye-1250MHz okwangoku isetyenziswa ikakhulu kunxibelelwano lwesathelayithi kunye neenkqubo zokukhangela. Ngophuhliso lwetekhnoloji kunye nohlengahlengiso lwemigaqo-nkqubo yolawulo lwe-spectrum, ububanzi besicelo sale bhanti kulindeleke ukuba kwandiswe ngakumbi.
