title="數(shù)字對講機">數(shù)字對講機產(chǎn)品。這次發(fā)布的對講機產(chǎn)品，不僅成為我國對講機數(shù)字化自主知識產(chǎn)權的里程碑，更具深遠意義的是，這些配備國產(chǎn)芯片的數(shù)字對講機填補了國內(nèi)中低檔數(shù)字對講機產(chǎn)品的空白，極大地推動了民族對講機產(chǎn)業(yè)的發(fā)展，將開啟我國數(shù)字對講機制造的新時代。

    由40家專業(yè)數(shù)字無線通信技術知名企業(yè)、科研機構(gòu)和高等院校共同組成的專業(yè)數(shù)字無線通信技術聯(lián)盟成立于2011年8月，該聯(lián)盟致力于促進150MHz～400MHz頻段專用對講機頻率的合理規(guī)劃和利用，促進中國自主知識產(chǎn)權標準的研究和制定，同時積極推動專業(yè)無線通信從模擬技術全面邁向數(shù)字技術。

    2009年12月12日，國家工業(yè)和信息化部正式發(fā)布了《關于150MHz400MHz頻段專用對講機頻率規(guī)劃和使用管理有關事宜的通知（工信部無[2009]666號文件）》，旨在滿足社會對數(shù)字對講機的使用需求，促進數(shù)字對講機的健康發(fā)展，進一步提高頻譜利用率。文件明確申明“自2011年1月1日起，停止對150MHz、400MHz頻段內(nèi)模擬對講機設備的型號核準，已取得型號核準證的模擬對講機設備，在型號核準證到期后不再予以辦理延期手續(xù)”。隨著該文件的發(fā)布，模轉(zhuǎn)數(shù)的進程有了明確的時間表。

    面對國內(nèi)“模轉(zhuǎn)數(shù)”的大勢所趨，如何更為全面、準確地推進工信部無[2009]666號文件、促進專業(yè)數(shù)字無線通信技術的標準化，普及DMR標準的應用，成為國內(nèi)對講機產(chǎn)業(yè)面臨的首要課題。CDMR聯(lián)盟也因此應運而生，并很快發(fā)展成為國內(nèi)眾多對講機制造企業(yè)和相關行業(yè)機構(gòu)積極響應，影響力輻射至對講機產(chǎn)業(yè)鏈方方面面的重要組織機構(gòu)。CDMR聯(lián)盟認為，CDMR產(chǎn)品標準以DMR數(shù)字通信技術為基礎，在第一、二層協(xié)議上做到了與DMR完全相符，從而避免不同型號數(shù)字對講機之間的制式?jīng)_突，也降低了對講機的采購成本。

    CDMR聯(lián)盟秘書處負責人高森先生表示：“作為全球普及率最廣的數(shù)字對講機標準，DMR制式有著其它制式無法比擬的優(yōu)勢，其入門門檻更低，更便于進行大規(guī)模集成化的生產(chǎn)。依托該標準，我國的CDMR產(chǎn)品根據(jù)國內(nèi)企業(yè)用戶的使用需求，在信道、頻率等使用方面，以及芯片、整機等生產(chǎn)環(huán)節(jié)都實現(xiàn)了與國際標準接軌，從而避免了不同產(chǎn)品的制式?jīng)_突。中國是全球?qū)χv機的生產(chǎn)大國，擁有超過80%的對講機生產(chǎn)廠商。此次CDMR聯(lián)盟的八家成員廠商攜手發(fā)布全新的基于DMR標準的數(shù)字對講機產(chǎn)品，可以說締造了國內(nèi)對講機行業(yè)的一個標志性的開端，同時起到了帶動更多對講機制造企業(yè)的作用。在未來，我們將繼續(xù)努力推廣CDMR產(chǎn)品，積極扶持民族對講機產(chǎn)業(yè)，加速與國際對講機產(chǎn)業(yè)的技術融合。”

    高森先生表示，此次發(fā)布的全新數(shù)字對講機產(chǎn)品全部采用了由清華大學自主研發(fā)的聲碼器及無錫士康通訊技術有限公司的基帶芯片，并且全部由中國本地著名的對講機生產(chǎn)廠家生產(chǎn)。可以說是百分之百的“中國心，中國造”。在產(chǎn)品的研發(fā)與生產(chǎn)過程當中，全球領先的數(shù)字對講機提供商摩托羅拉系統(tǒng)也在技術專利上給予了極大的支持。在未來，CDMR聯(lián)盟將繼續(xù)擴大其成員規(guī)模，推動CDMR數(shù)字通信技術在各行業(yè)的廣泛應用，提高企業(yè)的生產(chǎn)效益及政府部門的工作效率，加速國內(nèi)對講機行業(yè)的飛速發(fā)展。
