Kusanthula kwa kagwiritsidwe ntchito ndi kugawa kwa gulu la ma frequency la 1250MHz

Bandi ya ma frequency ya 1250MHz ili ndi malo ofunikira kwambiri pa wailesi ndipo imagwiritsidwa ntchito kwambiri m'magawo monga kulumikizana kwa satellite ndi makina oyendera. Kutalikirana kwake kwa ma signal ndi kuchepa kochepa kumapatsa ubwino wapadera pa ntchito zinazake.

Madera akuluakulu ogwiritsira ntchito:

Kulankhulana ndi Satellite: Bandi ya 1250MHz imagwiritsidwa ntchito makamaka polankhulana pakati pa ma satelite ndi malo oimikapo magalimoto pansi. Njira yolankhulirana iyi imatha kufikira malo ambiri, ili ndi ubwino wa mtunda wautali wotumizira ma signal komanso mphamvu yolimbana ndi zosokoneza, ndipo imagwiritsidwa ntchito kwambiri m'magawo monga kuwulutsa pa wailesi yakanema, kulumikizana pafoni ndi kuwulutsa pa satelite.

Dongosolo loyendera: Mu gulu la ma frequency la 1250MHz, gulu la ma frequency la L2 la Global Satellite Positioning System (GNSS) limagwiritsa ntchito ma frequency awa poika malo ndi kutsatira molondola. GNSS imagwiritsidwa ntchito kwambiri pa mayendedwe, ndege, kuyenda pa sitima komanso kufufuza za nthaka.

Momwe magawidwe a sipekitiramu alili panopa:

Malinga ndi "Malamulo Ogawa Ma Radio Frequency a People's Republic of China", dziko langa lapanga magawo atsatanetsatane a ma radio frequency kuti akwaniritse zosowa za mabizinesi osiyanasiyana.

Komabe, chidziwitso chapadera cha kugawa kwa band ya ma frequency ya 1250MHz sichinafotokozedwe mwatsatanetsatane mu chidziwitso cha anthu onse.

Kusintha kwa magawidwe a sipekitiramu yapadziko lonse lapansi:

Mu Marichi 2024, maseneta aku US adapereka lingaliro la Spectrum Pipeline Act ya 2024, akupereka lingaliro logulitsa ma frequency band ena pakati pa 1.3GHz ndi 13.2GHz, zomwe zikutanthauza kuti ma spectrum resources onse a 1250MHz, azitha kupititsa patsogolo chitukuko cha ma network a 5G amalonda.

Chiyembekezo cha Mtsogolo:

Chifukwa cha chitukuko cha ukadaulo wolumikizirana opanda zingwe, kufunikira kwa zinthu zolumikizirana kukukula. Maboma ndi mabungwe oyenerera akusintha njira zogawa ma spectrum kuti akwaniritse zosowa za ukadaulo ndi ntchito zomwe zikubwera. Monga spectrum yapakati, band ya 1250MHz ili ndi makhalidwe abwino ofalitsa ndipo ingagwiritsidwe ntchito m'magawo ambiri mtsogolo.

Mwachidule, gulu la 1250MHz pakadali pano limagwiritsidwa ntchito kwambiri mu njira zolumikizirana ndi ma satellite. Ndi chitukuko cha ukadaulo ndi kusintha kwa mfundo zoyendetsera ma spectrum, kuchuluka kwa kugwiritsa ntchito gululi kukuyembekezeka kukulitsidwa kwambiri.
