Whakaahuatanga Hua

TETRA taura-uru MDAS Fiber Optic Repeater ka whakamahia hei whakanui i te tohu o nga taputapu TETRA.Ka hopuhia e te Master Optical Unit System te tohu BTS o TETRA ka huri hei tohu optic me te tuku i te tohu whakahiato ki te Waehanga Optical Mamao ma nga taura muka.Ka huri ano te Waehanga Optical Mamao i te tohu whatu ki te tohu TETRA katahi ka whakawhiti i te Whakanuia Downlink me te whakarato i te tohu ki nga waahi kaore i te tika te kapi mahi kupenga.

Na ka whakanuia ano te tohu pūkoro ka tukuna ano ki te BTS ma te huarahi rereke.Ko te punaha tohatoha a to taatau kamupene rangahau motuhake me te whakawhanaketanga he mea tito e te Waehe Matapihi Matua me te Waehe Maama Mamao.Ko te waahanga o roto kei te whakauru, ko te hangarau tino whakauru kei te whakapai ake i te pumau o nga taputapu.

Nga waahanga hua

Te taumata teitei, te waatea nui, te watea mo te tiaki;

Ka mau i roto i te aro turuki mohio, he watea ki te kimi i nga hapa hei tiaki;

He iti te kaha o te kaha, he pai te tohanga wera;

PA linearity teitei, whiwhi pūnaha teitei;

Te aroturuki i te rohe me te tawhiti;

Rahi kiato, ngawari mo te whakaurunga me te nuku;

ETSI hototahi

Waihanga Matua

400 uhf tohu waea tukurua hono hono Nga waahanga:

1.Ka taea te whakapai ake i te rorohiko aroturuki i te takiwa, i tawhiti ranei.

2.Wide awhe hihiri, iti te kohi hiko me te ahua haruru.Te parenga mai i te ngaohiko teitei, te nui o te naianei me te nui o te pāmahana

3.High wehenga mai i te uplink ki te downlink ki te whakapai ake te pūmautanga tiketike.

4.High reliability me MTBF≥100,000 haora

5.Perfect mahi aroturuki whatunga mamao me te rohe.

6.Avoid pokanoa i te tahi-auau

7. Whakanuia te rohe kapi me te antenna ahunga omni

8Whakaroahia te tawhiti tohu o te teihana turanga

9.Backup pākahiko

10.Main kōwae whakamātautau whaiaro me te whakaoho aunoa.

11.Kuaha tuwhera whakaoho

12ALC(mana taumata aunoa), etc.

Taupānga&tauariari

TETRA 400 REPEATER Tono
Hei whakawhänui i te kapi tohu mo te whakaki i te waahi matapo tohu e ngoikore ana te tohu
kore wātea ranei.
Waho: Taunga rererangi, Rohe Tapoi, Papa korowha, Tunnels, wheketere, Takiwa keri, kainga etc.
Roto: Hotera, Whare Whakaaturanga, Raro, Hokohoko
Nga Toa, Nga Tari, Te Taapaki Lot etc.
Ko te nuinga e pa ana ki nga keehi penei:
Ka kitea e te kaitahuri he waahi whakaurunga ka taea te whiwhi tohu BTS parakore i te taumata kaha na te mea ko te Taumata Rx i te waahi tukurua kia neke ake i te ‐70dBm;

A ka taea e koe te whakatutuki i nga whakaritenga o te wehenga antenna kia kore ai e whakapouri i a koe ano.
