Chii chinonzi Critical communications?

Kukurukurirana kwakakosha kunoreva kuchinjana kweruzivo rwakakosha pakushanda nekuchengetedzeka kwevanhu, masangano, kana nzanga yese. Nhaurirano idzi dzinowanzoita nguva uye dzinogona kusanganisira nzira dzakasiyana siyana uye matekinoroji. Nhaurirano dzakakosha dzinoita basa rakakosha mumamiriro ekukurumidzira, kuchengetedzwa kweveruzhinji, uye masevhisi akakosha.

Mabhendi efrequency anoshandiswa pakutaurirana kwakakosha anosiyana zvichienderana nechikumbiro uye dunhu. Zvikamu zvakasiyana uye masangano anogona kushandisa akasiyana frequency mabhendi zvichienderana nekugoverwa kwemitemo, zvinodiwa zvehunyanzvi, uye kudiwa kwekudyidzana. Heano mamwe anowanzo shandiswa frequency mabhendi ekukurukurirana kwakakosha:

1. VHF (Yakanyanya Kuwanda Frequency) uye UHF (Ultra High Frequency):
   • VHF (30-300 MHz): Inowanzo shandiswa kune veruzhinji kuchengetedza kutaurirana, kusanganisira mapurisa, moto, uye masevhisi ekukurumidzira.
   • UHF (300 MHz - 3 GHz): Inowanzo shandiswa kune ese ari maviri kuchengetedzwa kweveruzhinji uye akavanzika masisitimu ekutaurirana.
2. 700 MHz uye 800 MHz mabhendi:
   • 700 MHz: Inoshandiswa kune veruzhinji kuchengetedza kutaurirana, kunyanya muUnited States.
   • 800 MHz: Inoshandiswa kune akasiyana akakosha masisitimu ekutaurirana, anosanganisira kuchengetedzwa kweveruzhinji, zvekushandisa, uye zvekufambisa.
3. TETRA (Terrestrial Trunked Radio):
   • TETRA inoshanda mubhendi reUHF uye inoshandiswa zvakanyanya kune nyanzvi dzenharembozha (PMR) masisitimu, kunyanya muEurope. Inopa kutaurirana kwakachengeteka uye kwakanyatso kuchengetedzwa kwevanhu uye zvimwe zvakakosha zvinoshandiswa.
4. P25 (Chirongwa 25):
   • P25 musutu wezviyero zvedhijitari redhiyo kutaurirana zvakagadzirirwa kushandiswa neveruzhinji kuchengetedza masangano muNorth America. Inoshanda muVHF, UHF, uye 700/800 MHz mabhendi.
5. LTE (Kushanduka Kwenguva Yakareba):
   • LTE, inowanzobatanidzwa neyekutengesa nharembozha, iri kuwedzera kugamuchirwa kune yakakosha kutaurirana, ichipa Broadband data kugona kwekuchengetedza veruzhinji uye zvimwe zvakakosha maapplication.
6. Satellite Communication:
   • Kukurukurirana neSatellite kunoshandiswa kutaurirana kwakakosha munzvimbo dziri kure kana njodzi uko zvivakwa zvepasi zvechinyakare zvinogona kukanganisa. Mabhendi akasiyana-siyana akagoverwa kutaurirana setiraiti.
7. Microwave Bands:
   • Microwave frequencies, senge idzo dziri mu2 GHz uye 5 GHz mabhendi, dzimwe nguva anoshandiswa pakunongedza-ku-point kutaurirana muzvivakwa zvakakosha, zvinosanganisira zvekushandisa uye zvekufambisa.

Semugadziri wenyanzvi weRF zvikamu, kufananaisolators, circulators,uyefilters, Jingxin inogadzira uye inogadzira mhando dzakasiyana dzezvikamu kutsigira mhinduro dzekukurukurirana kwakakosha. Makasununguka kutibata nesu @sales@cdjx-mw.com for more information.
