- TETRA (Terrestrial Trunked Radio) yobwerezabwereza yopangidwa kuti izithandizira ma netiweki otetezedwa ndi anthu komanso makina akatswiri apawailesi am'manja pamapulogalamu otetezedwa kwambiri, monga ma netiweki apansi panthaka, kapena mafakitale amafuta ndi gasi.Bi-Directional Amplifier (BDA) imatha kukulitsa ma siginowo mwa kusankha, kuwonetsetsa kuti ma siginoloji amabwerezedwa pafupipafupi komanso kukhazikika kwa mphamvu yotulutsa.Ili ndi kuyanjana kwabwino kwambiri ndipo tsopano imagwiritsidwa ntchito kwambiri pamakina olumikizirana otsika monga TETRA, iDEN.
Kingtone imapereka mayankho osiyanasiyana a tetra wailesi ndi machitidwe obwereza kuti akwaniritse zosowa za mabungwe ogwiritsa ntchito a Professional Mobile Radio.
- Nkhani yayikulu
-
◇ Mkulu mzere PA;Kupindula kwakukulu kwadongosolo;
◇ Ukadaulo wanzeru wa ALC;
◇ Full duplex ndi kudzipatula mkulu kuchokera uplink mpaka downlink;
◇ Makinawa Ogwiritsa ntchito bwino;
◇ Njira yophatikizika yokhala ndi magwiridwe antchito odalirika;
◇ Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi & chiwongolero chakutali;
◇ Mapangidwe osagwirizana ndi nyengo pokhazikitsa nyengo zonse;
- Ntchito & zochitika
- Obwerezabwereza a TETRA Fiber Optical amapereka chidziwitso m'nyumba zazing'ono, zapakati, zazikulu komanso zamasukulu, mkati mwa tunnel, metro ndi madera akutali kapena akumidzi.
