韓國(guó)三星電子(Samsung Electronics)宣布率先開(kāi)發(fā)出在毫米波(millimeter-wave) Ka頻段運(yùn)作、支持蜂窩通訊的的自適應(yīng)數(shù)組收發(fā)器(adaptive array transceiver)技術(shù)；該公司表示，此新技術(shù)將會(huì)是未來(lái)“5G”移動(dòng)通訊系統(tǒng)的核心，將可提供比目前 4G 網(wǎng)絡(luò)高數(shù)百倍的傳輸速率。
三星預(yù)期， 5G 通訊時(shí)代將在2020年左右來(lái)臨，將為使用者提供無(wú)所不在的Gbps等級(jí)通訊體驗(yàn)，屆時(shí)每個(gè)基站都可達(dá)到數(shù)十Gbps的傳輸速率。而迄今產(chǎn)業(yè)界幾乎還沒(méi)開(kāi)始推動(dòng)所謂的5G技術(shù)標(biāo)準(zhǔn)；在世界許多地區(qū)，支持 4G 技術(shù)的網(wǎng)絡(luò)甚至尚未布署。
根 據(jù)三星的說(shuō)法，高速率 5G 蜂窩網(wǎng)絡(luò)需要很大范圍的頻寬，就像是若想加強(qiáng)水流量就要更粗的水管那樣；而一直以來(lái)毫米波因?yàn)榫邆洳焕麄鞑サ奶匦?，都被認(rèn)為在長(zhǎng)距離傳輸資料方面有其限 制，但新的自適應(yīng)數(shù)組收發(fā)器技術(shù)能在28GHz頻段以1.056Gbps速率傳輸信息，傳輸距離可達(dá)2公里。
三星指出，該自適應(yīng)數(shù)組收發(fā)器技術(shù)采用64個(gè)天線單元，能有效克服毫米波頻段的無(wú)線電傳播耗損──比傳統(tǒng)頻段高出幾百M(fèi)Hz到數(shù)GHz──問(wèn)題。該公司也表示將加速5G技術(shù)的研發(fā)，預(yù)定在2020年將毫米波頻段的自適應(yīng)數(shù)組收發(fā)器技術(shù)商業(yè)化。

而三星也預(yù)期該公司在5G技術(shù)的最新研發(fā)成果，將催生全球相關(guān)產(chǎn)業(yè)聯(lián)盟的成立，并激勵(lì)5G移動(dòng)寬頻相關(guān)服務(wù)在適當(dāng)時(shí)機(jī)問(wèn)世。

Samsung wants to launch 5G in 2020
Dylan McGrath
South Korean giant claims first adaptive array transceiver technology operating in the millimeter-wave bands. Samsung Electronics Co. Ltd. said it has developed the world's first adaptive array transceiver technology operating in the millimeter-wave Ka bands for cellular communications. The South Korean giant said the new technology forms the core of a 5G mobile communications system and can provide data transmission up to several hundred times faster than 4G networks.
According to Samsung, 5G, which Samsung hopes to have available around 2020, will be capable of providing a ubiquitous Gbps experience to subscribers anywhere and offers data transmission speeds of up to several tens of Gbps per base station.
To date, there has been almost no standardization effort around 5G. In many parts of the world, equipment supporting 4G has not yet been deployed.
According to Samsung, the implementation of a high-speed 5G cellular network requires a broad band of frequencies, much like an increased water flow requires a wider pipe. Tt has been long believed that the millimeter-wave bands had limitations in transmitting data over long distances due to its unfavorable propagation characteristics, Samsung said.
But the new adaptive array transceiver technology transmits data in the millimeter-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to 2 kilometers, Samsung said. The firm maintains that the adaptive array transceiver technology, using 64 antenna elements, can be a viable solution for overcoming the radio propagation loss at millimeter-wave bands, much higher than the conventional frequency bands ranging from several hundred MHz to several GHz.
Samsung said it plans to accelerate the research and development of 5G technologies, including adaptive array transceiver at the millimeter-wave bands, to commercialize those technologies by 2020.
Samsung expects its latest innovation to spur research into 5G across the world, triggering the creation of international alliances and the timely commercialization of related mobile broadband services.
