Hoʻohana nui ʻia ka mea hoʻohui e hoʻohui i nā hōʻailona ʻōnaehana lehulehu i kahi hoʻonohonoho o nā ʻōnaehana hoʻolaha i loko. I nā noi ʻenehana, pono ʻo RF Multiplexer e hoʻohui i nā alapine ʻelua o 800MHz C network a me 900MHz G network e hoʻopuka. Hiki i ka hoʻohana ʻana i ka hui hui ke hiki i kahi ʻōnaehana hoʻolaha i loko e hana like i ka manawa hoʻokahi ma ke kāʻei alapine CDMA a me ka band frequency GSM. ʻO kekahi laʻana i loko o kahi ʻōnaehana antenna radio, RF Multiplexer ma hope o ka hoʻohui ʻana i nā hōʻailona hoʻokomo a me nā hōʻailona hoʻopuka o nā ʻāpana alapine like ʻole (e like me 145MHZ a me 435MHZ) ma o ka hui pū ʻana, hoʻohana ʻia kahi mea hānai e hoʻopili ai i ka lekiō, RF Multiplexer ʻaʻole e mālama wale i kahi. mea hānai, akā pale pū i ka pilikia o ka hoʻololi ʻana ma waena o nā antenna like ʻole.
Eia kekahi, pono e hoʻomaopopo ʻia i ka hoʻohana ʻana o ka hui hui, RF Multiplexer ke ala hānai hōʻailona o ka base station a i ʻole repeater he uea, a ʻo ke kumu o ka hōʻailona he ākea ākea, no laila i kekahi mau manawa, RF Multiplexer kahi haiki. pono ka passband e hōʻoia i ka maʻemaʻe o ka hōʻailona; ʻO ke ala hānai hōʻailona o ka transmitter he kaula, RF Multiplexer a lawe pololei ʻia ka hōʻailona mai kahi kumu hilinaʻi, a ʻo kāna kumu hōʻailona he hōʻailona kikoʻī kikoʻī. ʻO RF Multiplexer no ka mea ʻo ke kumu he hōʻailona alapine lawe, ʻo ke ʻano hānai he kaula, RF Multiplexer a aia wale ke kahawai. Hōʻailona alapine o ka mea lawe, ʻaʻohe hōʻailona hoʻopilikia ʻē aʻe. No laila, hiki i ka RF Multiplexer ke hoʻolālā ākea ākea o ka hui hui i nā noi kūpono.
Ma ke ʻano he ʻoihananā ʻāpana passivemea hana, hoʻokipa e nīnau iā mākou inā loaʻa iā ʻoe nā koi huahana.
