Iyo 1250MHz frequency bhendi inogara pachinzvimbo chakakosha muredhiyo spectrum uye inoshandiswa zvakanyanya muminda senge setiraiti yekutaurirana uye masisitimu ekufambisa. Yayo yakareba chiratidzo chekufambisa chinhambwe uye yakaderera attenuation inopa iyo yakasarudzika mabhenefiti mune chaiyo maapplication.
Nzvimbo huru dzekushandisa:
Satellite kutaurirana: Iyo 1250MHz frequency bhendi inonyanya kushandiswa kutaurirana pakati pema satellite uye pasi zviteshi. Iyi nzira yekukurukurirana inokwanisa kuwana kuvharika kwenzvimbo yakafara, ine zvakanakira zvechinhambwe chekufambisa kwemasaini uye kugona kwakasimba kwekusavhiringidza, uye inoshandiswa zvakanyanya mundima dzakadai senhepfenyuro yeterevhizheni, nharembozha uye kutepfenyura setiraiti.
Navigation system: Muiyo 1250MHz frequency bhendi, iyo L2 frequency bhendi yeGlobal Satellite Positioning System (GNSS) inoshandisa iyi frequency kurongedza chaiko nekutevera. GNSS inoshandiswa zvakanyanya mukufambisa, muchadenga, kufamba kwengarava uye kuongorora geological.
Parizvino mamiriro ekugoverwa kwe spectrum:
Zvinoenderana ne "Radio Frequency Allocation Regulations yePeople's Republic of China", nyika yangu yakaita kupatsanurwa kwakadzama kwemaredhiyo eredhiyo kuzadzisa zvinodiwa nemabhizinesi akasiyana.
Nekudaro, iyo chaiyo yekugovera ruzivo ye1250MHz frequency bhendi haina kutsanangurwa muruzivo rweveruzhinji.
International spectrum allocation dynamics:
Muna Kurume 2024, maseneta eUS akakurudzira Spectrum Pipeline Act ye2024, vachikurudzira kutengesa mamwe ma frequency mabhendi pakati pe1.3GHz ne13.2GHz, anosvika 1250MHz ezviwanikwa zve spectrum, kusimudzira kusimudzira kwekutengesa 5G network.
Ramangwana Outlook:
Nekukurumidza kuvandudzwa kwewireless kutaurirana tekinoroji, kudiwa kwezviwanikwa zve spectrum kuri kukura. Hurumende uye masangano akakodzera ari kushingaira kugadzirisa nzira dzekugovera spectrum kuti dzizadzise zvinodiwa zvemichina uye mabasa ari kusimukira. Seyepakati-bhendi spectrum, iyo 1250MHz bhendi ine yakanaka yekuparadzira maitiro uye inogona kushandiswa mune mamwe minda mune ramangwana.
Muchidimbu, iyo 1250MHz bhendi parizvino inonyanya kushandiswa mune satellite kutaurirana uye masisitimu ekufambisa. Nekuvandudzwa kwetekinoroji uye nekugadziriswa kweiyo spectrum manejimendi marongero, chiyero chekushandisa chebhendi ichi chinotarisirwa kuwedzerwa.
