TETRA chingwe chofikira MDAS Fiber Optic Repeater imagwiritsidwa ntchito kukulitsa chizindikiro cha zida za TETRA.Master Optical Unit System imagwira chizindikiro cha BTS cha TETRA ndikuchisintha kukhala chizindikiro cha optic ndikutumiza chizindikirocho ku Remote Optical Unit kudzera pazingwe za fiber optic.Remote Optical Unit idzasinthanso chizindikiro cha optic kukhala chizindikiro cha TETRA ndiyeno itembenuzire Downlink Amplifier ndikupereka chizindikiro kumadera omwe kusagwira ntchito kwaukonde sikukwanira.

Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwanso ku BTS kudzera mbali ina.Dongosolo logawa ndi kampani yathu yodziyimira pawokha kafukufuku ndi chitukuko limapangidwa ndi Master Optical Unit ndi Remote Optical Unit.Gawo lamkati limaphatikizidwa, ukadaulo wophatikizika kwambiri ndikuwongolera kukhazikika kwa zida.

Zogulitsa Zamalonda

Mulingo wapamwamba, kupezeka kwakukulu, koyenera kukonza;

Internal kutengera kuwunika kwanzeru, ndikosavuta kupeza zolakwikazo kuti zisungidwe;

Kugwiritsa ntchito mphamvu zochepa, kutentha kwabwino kwambiri;

Mzere wapamwamba PA, kupindula kwakukulu kwadongosolo;

Kuyang'anira kwanuko ndi kutali;

Kukula kocheperako, kusinthika pakukhazikitsa ndi kusamutsa;

Zogwirizana ndi ETSI

Nkhani yayikulu

400 uhf mafoni ulalo ulalo wobwereza Mbali:

1.Monitoring mapulogalamu akhoza kukwezedwa kwanuko kapena kutali.

2.Wide yosinthika, kugwiritsa ntchito mphamvu zochepa komanso phokoso la phokoso.Kutetezedwa kumagetsi opitilira muyeso, kupitilira apo komanso kutentha kwambiri

3.Kudzipatula kwapamwamba kuchokera ku uplink kupita ku downlink kuti mukhale okhazikika kwambiri.

4.Kudalirika kwakukulu ndi MTBF≥100,000 maola

5.Perfect kutali ndi ntchito zowunikira maukonde.

6.Pewani kusokonezedwa ndi ma co-frequency

7.Kulitsani malo ophimba ndi mlongoti wa omni directional

8 Wonjezerani mtunda wa ma sign of base station

9.Batire zosunga zobwezeretsera

10.Main module kudziyesa nokha ndi alamu galimoto.

11.Door open alarm

Zimagwiritsidwa ntchito makamaka pazochitika zotere:
Wobwereza amatha kupeza malo osungira omwe angalandire chizindikiro choyera cha BTS pamlingo wokwanira monga Rx Level mu malo obwereza ayenera kukhala oposa -70dBm;

Ndipo amatha kukwaniritsa kufunikira kwa kudzipatula kwa mlongoti kuti apewe kudzidzidzimutsa.
