Hōʻike huahana

Hoʻohana ʻia ʻo TETRA cable-access MDAS Fiber Optic Repeater e hoʻonui i ka hōʻailona o nā lako TETRA.Lawe ka Master Optical Unit System i ka hōʻailona BTS o TETRA a hoʻololi iā ia i hōʻailona optic a hoʻouna i ka hōʻailona hoʻonui i ka Unit Optical mamao ma o nā kaula fiber optic.Na ka Remote Optical Unit e hoʻohuli hou i ka hōʻailona optic i ka hōʻailona TETRA a laila e kamaʻilio i ka Downlink Amplifier a hāʻawi i ka hōʻailona i nā wahi i lawa ʻole ai ka uhi o ka hana.

A hoʻonui ʻia ka hōʻailona kelepona a hoʻouna hou ʻia i ka BTS ma ke ala ʻē aʻe.ʻO ka ʻōnaehana hoʻolaha e kā mākou hui noiʻi kūʻokoʻa a me ka hoʻomohala ʻana i haku ʻia e Master Optical Unit a Remote Optical Unit.Hoʻohuiʻia ka module i loko,ʻo kaʻenehana hoʻohui nui e hoʻonui i ka paʻa o nā mea hana.

Kiʻekiʻe kiʻekiʻe, kiʻekiʻe loaʻa, kūpono no ka mālama;

Hoʻohana i ka nānā ʻana i ka naʻauao, maʻalahi ke ʻimi i nā hewa no ka mālama ʻana;

ʻO ka hoʻohana haʻahaʻa haʻahaʻa, hoʻopau wela maikaʻi loa;

Linearity kiʻekiʻe PA, kiʻekiʻe pūnaewele loaʻa;

Mākaʻikaʻi kūloko a mamao;

ʻO ka nui paʻa, hiki ke maʻalahi no ka hoʻokomo a me ka neʻe ʻana;

Hiʻona nui

ʻO 400 uhf pūnaewele hōʻailona loulou repeater mau hiʻohiʻona:

1.Monitoring lako polokalamu hiki ke upgrade locally a remotely.

2.Wide dynamic range, haʻahaʻa mana hoʻohana a me ka walaʻau helu.Ka pale ʻana mai ka overvoltage, ma luna o kēia manawa a ma luna o ka wela

3.High kaawale mai ka uplink i ka downlink e hoʻomaikaʻi kiʻekiʻe paʻa.

4.High hilinaʻi a me MTBF≥100,000 hola

5.Perfect mamao a me ka 'oihana mālama pūnaewele.

6.Avoid keakea mai co-frequency

7. Enlarge i ka uhi wahi me omni directional antenna

8E hoʻonui i ka mamao hōʻailona o ke kahua kahua

9.Backup nā pila

10.Main module ho'āʻo ponoʻī a me ka alarm auto.

11. Puka wehe ʻana i ka alarm

12ALC (auto pae mana), etc.

Hoʻohana a me nā hiʻohiʻona

Nā noi TETRA 400 REPEATER
No ka hoʻonui ʻana i ka uhi hōʻailona o ka hoʻopiha ʻana i ka wahi makapō hōʻailona kahi nāwaliwali o ka hōʻailona
ʻaʻole loaʻa.
Ma waho: nā mokulele, nā wahi mākaʻikaʻi, nā papa kolepa, nā tunnels, nā hale hana, nā ʻāpana mining, nā kauhale etc.
Loko: Hotele, Hale Hōʻikeʻike, Basements, Kūʻai
ʻO nā hale kūʻai, nā keʻena, nā pahu pahu etc.
Hoʻohana nui ʻia i kēlā ʻano hihia:
Hiki i ka mea hana hou ke loaʻa kahi wahi hoʻokomo i hiki ke loaʻa i ka hōʻailona BTS maʻemaʻe ma ka pae ikaika e like me ka Rx Level ma ka pūnaewele repeater e ʻoi aku ma mua o ‐70dBm;

A hiki ke hoʻokō i ke koi o ka hoʻokaʻawale ʻana i nā antenna e pale aku iā ʻoe iho-oscillation.
