Kuwunika kwa kugwiritsa ntchito ndi kugawa kwa 1250MHz frequency band

Gulu la ma frequency a 1250MHz limakhala ndi malo ofunikira pamawonekedwe a wailesi ndipo limagwiritsidwa ntchito kwambiri m'magawo monga njira zolumikizirana ndi ma satellite ndi ma navigation system. Mtunda wake wautali wotumizira ma siginecha komanso kutsika kochepa kumaupatsa mwayi wapadera pamapulogalamu ena.

Malo ogwiritsira ntchito:

Kulankhulana kwa satellite: Gulu la ma frequency a 1250MHz limagwiritsidwa ntchito makamaka polumikizana pakati pa ma satellite ndi masiteshoni apansi. Njira yolankhuliranayi imatha kukwaniritsa kufalikira kwa madera ambiri, ili ndi ubwino wa mtunda wautali wotumizira mauthenga ndi mphamvu zotsutsana ndi kusokoneza, ndipo zimagwiritsidwa ntchito kwambiri m'madera monga kuwulutsa pawailesi yakanema, mauthenga a m'manja ndi kuwulutsa kwa satellite.

Navigation system: Mu 1250MHz frequency band, L2 frequency band ya Global Satellite Positioning System (GNSS) imagwiritsa ntchito ma frequency awa poyika komanso kutsatira. GNSS imagwiritsidwa ntchito kwambiri pazamayendedwe, zakuthambo, kuyenda pamadzi ndi kufufuza kwa geological.

Mkhalidwe wagawidwe wa sipekitiramu pano:

Malinga ndi "Radio Frequency Allocation Regulations of the People's Republic of China", dziko langa lagawa mwatsatanetsatane mawayilesi kuti akwaniritse zosowa zamabizinesi osiyanasiyana.

Komabe, zidziwitso zogawika za 1250MHz frequency band sizinafotokozedwe mwatsatanetsatane pagulu.

Kugawika kwa masipekitiramu kumayiko ena:

Mu Marichi 2024, maseneta aku US adakonza za Spectrum Pipeline Act ya 2024, akufuna kugulitsa ma frequency angapo pakati pa 1.3GHz ndi 13.2GHz, okwana 1250MHz yazinthu zowoneka bwino, kulimbikitsa chitukuko cha ma network a 5G.

Tsogolo lamtsogolo:

Ndi chitukuko chofulumira chaukadaulo wamalumikizidwe opanda zingwe, kufunikira kwazinthu zama sipekitiramu kukukulirakulira. Maboma ndi mabungwe okhudzidwa akusintha mwachangu njira zogawira masipekitiramu kuti akwaniritse zosowa zaukadaulo ndi mautumiki omwe akubwera. Monga gulu lapakati, gulu la 1250MHz lili ndi mawonekedwe abwino ofalitsa ndipo litha kugwiritsidwa ntchito m'magawo ambiri mtsogolo.

Mwachidule, gulu la 1250MHz pakadali pano limagwiritsidwa ntchito kwambiri pama satellite olankhulana ndi machitidwe oyenda. Ndi chitukuko chaukadaulo komanso kusintha kwa mfundo zoyendetsera ma spectrum, kuchuluka kwa kagwiritsidwe ntchito ka gululi kukuyembekezeka kukulitsidwa.
