Kodi Critical communications ndi chiyani?

Kulumikizana kofunikira kumatanthawuza kusinthana kwa chidziwitso chomwe chili chofunikira kwambiri pakugwira ntchito ndi chitetezo cha anthu, mabungwe, kapena gulu lonse. Kulankhulana kumeneku nthawi zambiri kumakhala kosavuta ndipo kumatha kuphatikizira njira ndi matekinoloje osiyanasiyana. Kulumikizana kofunikira kumagwira ntchito yofunika kwambiri pakagwa ngozi, chitetezo cha anthu, komanso ntchito zofunika.

Ma frequency omwe amagwiritsidwa ntchito polumikizirana movutikira amasiyana malinga ndi momwe akugwiritsidwira ntchito komanso dera. Magawo osiyanasiyana ndi mabungwe amatha kugwiritsa ntchito ma frequency osiyanasiyana kutengera kugawika kwamalamulo, zofunikira zaukadaulo, komanso kufunikira kogwirizana. Nawa magulu omwe amagwiritsidwa ntchito pafupipafupi polumikizirana movutikira:

1. VHF (Kuthamanga Kwambiri Kwambiri) ndi UHF (Ultra High Frequency):
   • VHF (30-300 MHz): Nthawi zambiri amagwiritsidwa ntchito polumikizirana ndi anthu, kuphatikiza apolisi, ozimitsa moto, ndi chithandizo chadzidzidzi.
   • UHF (300 MHz – 3 GHz): Nthawi zambiri amagwiritsidwa ntchito pachitetezo cha anthu komanso njira zoyankhulirana zachinsinsi.
2. 700 MHz ndi 800 MHz magulu:
   • 700 MHz: Amagwiritsidwa ntchito polumikizirana ndi anthu, makamaka ku United States.
   • 800 MHz: Imagwiritsidwa ntchito pamakina osiyanasiyana ovuta kulumikizana, kuphatikiza chitetezo cha anthu, zothandizira, ndi zoyendera.
3. TETRA (Terrestrial Trunked Radio):
   • TETRA imagwira ntchito mu gulu la UHF ndipo imagwiritsidwa ntchito kwambiri pamakina aukadaulo amafoni (PMR), makamaka ku Europe. Amapereka kulumikizana kotetezeka komanso koyenera kwa chitetezo cha anthu ndi ntchito zina zofunika.
4. P25 (Project 25):
   • P25 ndi mndandanda wamiyezo yamawayilesi a digito opangidwa kuti agwiritsidwe ntchito ndi mabungwe oteteza anthu ku North America. Imagwira m'magulu a VHF, UHF, ndi 700/800 MHz.
5. LTE (Kusintha Kwanthawi Yaitali):
   • LTE, yomwe nthawi zambiri imalumikizidwa ndi ma network am'manja amalonda, ikugwiritsiridwa ntchito kwambiri kuti ikhale yolumikizirana, yopereka kuthekera kwa data ya Broadband pachitetezo cha anthu ndi ntchito zina zovuta.
6. Kulankhulana kwa Satellite:
   • Kuyankhulana kwa satellite kumagwiritsidwa ntchito poyankhulana movutikira kumadera akutali kapena kochitika masoka komwe zida zapadziko lapansi zitha kusokonezedwa. Ma frequency osiyanasiyana amaperekedwa kuti azilumikizana ndi satellite.
7. Magulu a Microwave:
   • Ma frequency a Microwave, monga omwe ali m'magulu a 2 GHz ndi 5 GHz, nthawi zina amagwiritsidwa ntchito polumikizirana poyambira pazida zofunika kwambiri, kuphatikiza zothandizira ndi zoyendera.

Monga katswiri wopangaZigawo za RF, mongaodzipatula, ozungulira,ndizosefera, Jingxin imapanga ndikupanga mitundu yosiyanasiyana ya zigawo kuti zithandizire njira zoyankhulirana zovuta. Mwalandiridwa kuti mutilankhule @sales@cdjx-mw.com for more information.
