Tetra 380MHz Band Tīpakohia 380-385 MHZ 390-395 MHZ Rua Te Reo Irirangi UHF Wawaho Tohu Whakanui Whakanuia me te RJ45
Ko te roopu auau 380-385 MHz (uplink)/390-395 MHz (downlink) i hangaia hei whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu i te taapiri i te turanga turanga hou (BTS).Ko te mahi matua o te punaha RF Bi-Directional Amplifiers ko te whiwhi tohu iti-hiko mai i te BTS ma te tuku auau reo irirangi, katahi ka tuku i te tohu whakakaha ki nga waahi kaore i te tika te kapinga whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ki te BTS ma te huarahi rereke.
Nga Tohu Hua:
● Ki te hoahoa modularized, ngāwari mo te tiaki
● Pūmanawa aroturuki mamao (tauranga rangatū), ngāwari hokite tiaki me te whakahaere.
● IP55 dustproof & parewai, ki iti whakaritenga i runga i te taiao tāutanga;
● Ki te whakakaha kaha raina-nui me te duplexer paopao-nui, e kaha ana ki te whakahē i te intermodulation me nga tohu teka.
