Kingtone 43dBm 20W Tetra DMR UHF BDA Off-air Channel Selective Fiber Optic Repeater Signal Extender mo te Tunnel & In-Building DAS 400MHz Radio System Telecommunication

Whakaahuatanga Poto:

He aha te Repeater Fiber Optic? I hoahoatia te punaha Kingtone Fiber Optic Repeater ki te whakaoti rapanga o te tohu pūkoro ngoikore, he iti ake te utu i te tatūnga i te Teihana Turanga hou (BTS). Ko te mahi matua o te punaha Repeater RF: Mo te hononga ki raro, ka tukuna 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 hei whakanui ake ki te mana teitei ki te IBS, ki te antenna kapinga ranei. F...

    He aha te Repeater Fiber Optic? 
    I hoahoatia te punaha Kingtone Fiber Optic Repeater ki te whakaoti rapanga o te tohu pūkoro ngoikore, he iti ake te utu i te tatūnga i te Teihana Turanga hou (BTS). Ko te mahi matua o te punaha Repeater RF: Mo te hononga ki raro, ka tukuna 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 hei whakanui ake ki te mana teitei ki te IBS, ki te antenna kapinga ranei. Mo te hono ki runga, He mahi 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 haruru haruru iti 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.
