話說,從3G和4G開始,我們對這種起名方法就已經(jīng)不陌生了。不過,大家都知道這個G到底是什么意思嗎?3G、4G、5G又分別是什么呢?今天就讓小編來科普一下這個吧~
首先,這個 G 代表的是Generation(一代)5G 的全稱是 5th generation mobile networks,也就是“第五代移動網(wǎng)絡(luò)”。然后,5G 和 4G 相比,除了速度更快以外,它還能容納更大的用戶密度(user density)換句話說,扎堆上網(wǎng)拖網(wǎng)速的現(xiàn)象會減輕很多。而且它支持一種叫“設(shè)備到設(shè)備通訊”的技術(shù):Device-to-Device Communication(D2D)3G、4G網(wǎng)絡(luò)里,所有的設(shè)備之間,如果要傳遞信號,這些信號都需要經(jīng)過中轉(zhuǎn)站。而 5G 里面則可以通過這種 D2D 技術(shù)直接傳,這也是它的速度得以進(jìn)一步提升的原因之一。
