He ahaLTE Band 31 450MHz Mea Hana Hou?
LTE450, i ʻike ʻia ʻo band 31, he mau noi pūnaewele LTE pilikino e hoʻohana ana i kahi450MHz alapine.
Ke hoʻohana nei nā ʻupena kelepona ʻo Long-Term Evolution (LTE) i kekahi mau kaha alapine, Band 31, FDD, 450, NMT, 452.5 – 457.5, 462.5 – 467.5.
ʻO ka ʻokoʻa ʻokoʻa loa ma LTE 450 kona alapine haʻahaʻa, ma 450 MHz.Loaʻa nā alapine maʻamau o 900, 1800, 2100 a i ʻole 2600 MHz.Pono ke alapine o LTE 450, a i ʻole band 31 e like me ka mea i ʻike ʻia i kekahi manawa, pono i kahi module LTE 450 i hoʻolaʻa ʻia.Hāʻawi koke kēia i ka LTE 450 i kahi pōmaikaʻi ma ke ʻano o ka hōʻemi ʻana o ka hōʻailona.
ʻO LTE 450 ponoʻī kahi pūnaewele kamaʻilio uea ʻole e pili ana i kahi alapine 450 MHz.ʻO ka mea nui, ʻo ia kahi hui pūnaewele e hāʻawi i kahi ākea ākea, ke komo ʻana i ka hōʻailona hohonu, nā wikiwiki kiʻekiʻe a me ka pilina paʻa, hilinaʻi.
Hāʻawi ʻo Kingtone i ke kumukūʻai kiʻekiʻe o ka LTE Network Amplifier FDD LTE Band 31 450MHz Outdoor Band Selective Repeater, hoʻokipa i kāu nīnau!
Nā hiʻohiʻona nui
◇ PA linearity kiʻekiʻe;Loaʻa ʻōnaehana kiʻekiʻe；
◇ ʻenehana ALC akamai;
◇ Duplex piha a me kahi kaʻawale kiʻekiʻe mai ka uplink a i lalo;
◇ Hana maʻalahi ka hana;
◇ ʻenehana hoʻohui me ka hana hilinaʻi;
◇ Hiki ke hoʻonohonoho ʻia ka Bandwidth mai 5-25MHz i ka hui hana.
◇ Ka nānā 'āina a me ka mamao (koho) me ka 'akomi hewa alarm & remote control;
◇ ʻO ka hoʻolālā ʻana i ka weatherproof no ka hoʻokomo ʻana i nā wā āpau;
