Ko te punaha Kingtone JIMTOM® Fiber Optic Repeaters i hangaia hei whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu i te tatūnga i te Teihana Turanga (BTS) hou.Ko te mahi matua o te punaha Repeater RF: Mo te hononga ki raro, ka whangaihia nga tohu mai i te BTS ki te Waeine Matua(MU), ka huri te MU i te tohu RF ki te tohu laser ka whangai ki te muka hei tuku ki te Waeine Mamao (RU).Ka huri a RU i te tohu taiaho ki te tohu RF, ka whakamahi i te Power Amplifier ki te whakanui i te mana teitei ki te IBS, ki te antenna kapinga ranei.Mo te hono ki runga, He tukanga whakamuri, ka tukuna nga tohu mai i te waea pūkoro ki te tauranga MS a MU.Ma te duplexer, ka whakanuia te tohu e te iti o te haruru whakakaha hei whakapai ake i te kaha tohu.Na ka whangaihia nga tohu ki te RF muka optical module ka huri ki nga tohu laser, katahi ka tukuna te tohu laser ki MU, ka huri te tohu laser mai i te RU ki te tohu RF na te RF optical transceiver.Na ka whakanuia nga tohu RF ki nga tohu kaha ka whangaia ki te BTS.
Ko te RF Repeater i hangaia hei whakarei ake i te kapinga whatunga pūkoro me te whakakii i nga waahi matapo.Ko te mahi matua o te tukurua ko te whiwhi tohu iti-hiko mai i te Teihana Turanga (BS) ma te tuku irirangi (RF) na tana antenna kaituku, te tukatuka, te whakanui me te tuku i te tohu ki te Teihana Waea (MS) i roto i te rohe kapi i runga i tana ratonga. pūihi.
Nga waahanga matua
- Hangarau FPGA Base SDR, Te whakakoi mai i te whakakorenga whiwhi roopu;
- 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 aro turuki i te rohe me te mamao (he kowhiringa) me te whakaoho hapa aunoa & te mana mamao;
- Rahi kiato, ngawari mo te whakaurunga me te nuku;
- Te hoahoa huarere mo te whakaurunga o nga rangi katoa;
- Ka taea e tetahi MU te taraiwa Max 32 RU, Tiaki te utu me te ngawari ki te whakauru.
- Te mowhiti tautoko, te mekameka daisy, te topology whetu, te whakapai ake i te ngawari o te whatunga.
- Hoahoa kawe-maha, max 16 nga kaikawe, ngawari ki te hapai i nga ahuatanga tono waka nui
