5G牌照正式发放!网友:我刚买的4G手机凉凉?

今天上午8点40分,工业和信息化部举行了发牌仪式,颁发了国内首批 5G 牌照,中国电信、中国移动、中国联通、中国广电获得了中国首批 5G 商用牌照!

定了定了!来了来了!

今天上午8点40分,工业和信息化部举行了发牌仪式,国内三大运营商与广电、铁塔公司董事长参会。在会上工信部颁发了国内首批 5G 牌照,中国电信、中国移动、中国联通、中国广电获得了中国首批 5G 商用牌照!

p2

是的你没有看错,5G商用开始啦!

但是接着就有小伙伴紧张提问:刚买的4G手机诶,难不成都变砖啦?

p3

甭急,咱们下文慢慢聊~

啊~啊~5G~,你比4G多~1~G~

对于普通人来说,5G意味着什么?

“哦,手机上网速度又会快一点。”
“看视频不会卡了哎,但流量是不是耗得更快……”
“4G已经很快了,是不是还要换手机好烦啊。”

4G真的很快了吗?我们来看看它和5G的PK:

p4dongtu (1)

1.3Gbps!和5G相比4G真的是个弟弟了(滑稽)!

动图2 (3) (1)

你能跟上我~~的~~speed~~吗

除去1G,从2G到4G的每一代下载速度的增长幅度都达到几十倍,原来加载一个资讯页都要急得跳脚,现在则可以毫无压力地在移动端开一盘农药和吃鸡。用户得到的是新体验,从业者落地的是新玩法——

p5

而我们也看到了,从4G进入5G,又实现了夸张的跨越:峰值速率从4G的1G/s提升到20G/s,网络延迟从10ms降低至1ms,每平方米的数据吞吐量提升了100倍/s。

到了如此境界,5G的快已经意味着的是全方位生活形态的升级。

而且,这次升级还将以中国为中心。
在设计5G的应用场景时,中国IMT-2020推进小组的mMTC和URLLC两个场景直接被“国际电联”(ITU)采用,并与eMBB一起组成三个应用场景。

具体来说,这三个场景分别被称为:

mMTC:大规模机器通信。
URLLC:超可靠和低延迟通信。
eMBB:增强型移动宽带。

而下图可以大概展示三者分别对应的部分领域:

p6

通过几个5G的突出特点:高速、低延时、大容量,我们可以延伸一些想法。

01.万物智联AIoT

从互联互通,到设备智能,物联网IoT正升级成智能化的AIoT。但联结速度,云端数据处理量以及响应延迟的限制仍然未得到解决。但现在5G的落地将冲破限制。

02.联网游戏

网络游戏,尤其是高强度的联机对战,决定胜负的不仅是手速,更是网速。几秒的延时可能就会让你从优势很大瞬间被翻盘。这在5G时代几乎不会发生。

03.VR应用

抛开在游戏上的应用,VR在直播、在线贸易、线上购物等领域也有着广阔的前景。而只有在5G应用后,才能最大程度地让高清、高仿真、高实时性的VR落地。

04.远程医疗

线上遥控进行手术的概念早已有之,但在网速不稳定的情况下,画面的延迟将对医生的判断产生巨大的干扰。而在5G的高速环境下,以上风险将得到有效控制。

05.应用/小程序开发

5G的高速和低延迟,将方便开发者研发更高画质,更多交互手段的应用与小程序,让更多爆品落地。

中国成为定义5G使用场景的主要国家,对于我们而言是幸运的。作为普通民众,可以体验5G大范围且与国际标准接轨的场景应用;作为想在5G领域淘金的弄潮儿,则在起跑线上就具有了广阔的领域可供选择。

它们,让5G快得与众不同

在中小学的信息技术教材中,开篇的入门部分总会有个一笔带过的人名——香农

p7

香农:我在教科书应该更有排面才对

此公何许人也?是一个在各种意义上都可以被如今的通信业者叫一声“爸爸”的存在。简单列几件他做过的事:

提出信息论,指出信息可以被测量,并在“信道”中传输。为数字通信奠定了基础。
基于热力学首次提出“信息熵”概念,确立了基本单位“比特”,成为如今字节、KB、MB等单位的前身。

而跟本文最相关的,是他所创造的一个信道容量公式:

p8

这个公式的意义是指明了一件事,那就是最大数据传输速率(C)主要由两个要素决定:频带宽度(W)及信噪比(S/N)。两者值越高,数据传输速率越大。

基于香农公式的启发,即使到了5G,提速也一样绕不开提升频带宽度及信噪比,。

在频带宽度和信噪比两方面,5G做了以下事情:

01.引入毫米波频段

到4G为止,频谱均为300MHz-3GHz,虽然覆盖广,穿透性好,但问题也很明显——挤。四代以来所有设备都集中在这一段,想再提升传输速度与容量已经挪不出来更多频带宽度了!

怎么办?去别的频段,而3GHz以上的就是毫米波频段。

p9

5G可以从毫米波频段中取得252GHz的频宽,虽然实际用不上这么多,但也让提速扩容的“天地”瞬间广阔起来。

而根据今早发牌仪式的消息,中国电信获得3.4-3.5GHz的100MHz频谱资源,中国移动获得2515-2675Mhz的160MHz带宽的信息,中国广电则拥有“黄金频段”的700MHz。

02.波束赋形

波束赋形可以形象地理解为将一些散射的光收束聚焦,形成一条更明亮,能量更强的光线。

p10

5G的信号传输中,为了避免毫米波在传输途中的能量损耗,减轻复杂天气的影响,就将通过基站的大规模天线等设备进行波束赋形,提升信号能量、信噪比及覆盖范围。

自此,通过以上突破,5G的提速超乎想象。

关于5G的5个Q&A

好了,介绍完5G,我们再回到文章开头的问题:4G手机要不要换?同时还有其它各种好奇宝宝们的关注点,小智都来解答一下!

Q:现在的手机、手机号还能用吗?

A:要想用5G,还是得花钱换个支持5G的新手机的。当然,方法总比困难多。如果你跟小智一样穷困潦倒,咱也可以曲线救国:用手机WiFi连接CPE设备,以使用5G网络。而且4G的频段也仍会保留,这样不用着急换手机~

Q:5G啥时能用?

A:目测还需要1-2年的时间。运营商持牌上岗,5G应该能登台了,但各大运营商的5G网络还处于试点阶段,部署规模当前是比较小的。前期5G应不会大规模铺开,更多的是探索。

Q:最早啥时能买5G手机?

A:一般来说,牌照发放后,配套的5G手机要先送测,最快一个月给发入网证。因此,至少还得耐心等待月球转一圈的时间。

当然,对于各大品牌手机厂商来说,现阶段不会急于大规模上市,第一批5G手机主要是为了赚口碑,为以后市场推广铺路搭桥。好饭不怕晚,咱也等的起。

Q:5G套餐会更贵吗?

A:对于咱普通百姓来,套餐计费和现在应该相差无几。单位流量价格降低,但5G套餐的平均流量可能会比4G套餐增加不少。

不过与IoT、AI驾驶等相关新兴行业可能会采取更复杂的计费模式:按带宽、延时、和连接数量等多项指标收费。

Q:中国5G实力处于第几梯队?

A:第一梯队!第一梯队!!第一梯队!!!自豪的事说三遍!

5G会是我们的摆渡人吗?

截至此刻,特别想引经据典的和大家聊两句。

IBM创始人老沃森曾说:世界上只需要5台电脑。
比尔·盖茨曾说:640K内存足够了。
而现在也有人说:4G就够了。

真的就够了吗?人类追求梦想的步伐可以说比想象的大太多了。只要体验过高速网络带来的便利,就会推崇备至了。

诚然,电信业经历过辉煌,如今跌入低谷,但它从来都不曾一蹶不振。等待一个时机重返荒原,寻找自己的摆渡人,重回世间。

5G会是我们的摆渡人吗?

是的,当我们无从选择时,5G就是我们的摆渡人,它所承载的是电信业重振旗鼓的梦想。无论是技术、生态,还是商业模式,5G犹如一次脱胎换骨,满血复活的渴望。

最后,引用《星际迷航》的话收尾:

To boldly go where no man has gone before.
勇踏前人未至之境。

P11

好了,以上学霸发言结束~~
作为学渣本渣,小智想说
以上看不懂真的不重要!

5G时代,大家只要享受——

看视频不缓冲!
打排位不掉线!
几G文件秒下!

想想就很开心呢!

P12

最后,端午安康!高考的孩子们,加油!
