所有智能手机制造商和移动运营商都在谈论 5G 及其诸多好处。我们看到越来越多关于 5G 有多棒以及为什么应该拥有它的广告。但这是为什么呢？甚至反vaxxers 也痴迷于5G，而不仅仅是政府或智能手机制造商。在本文中，我们将解释 5G 是什么，5G 意味着什么，以及它的好处是什么：
什么是5G？5G是什么意思？
5G 不是来自 5 GHz、5 Gigabit 或我们通过疫苗注射的五个芯片。🙂 开个玩笑(Joke)，5G 只意味着第五代移动通信。就像(Just)4G 是第四代一样，3G 是第三代，以此类推。
5G 不仅仅是一种以某种方式实施的技术，而是一系列电信技术，它们共同构成了一个 5G 网络。构成 5G 基础设施的主要技术有：
- 毫米波(Millimeter)- 设备通过网络进行通信的频率或无线电波。在 5G 网络的情况下，与 4G 相比，可用的网络要多得多，但它们也更容易被墙壁、建筑物或雨雪等天气事件吸收。
- 小型(Small)蜂窝 - 传输用于 5G 连接的无线电波的互连中继。在城市地区，5G 网络需要更高密度的中继来传输数据。
- 大规模MIMO - 对(MIMO)Wi-Fi网络中的(Wi-Fi)MIMO技术的一种改编，例如由家庭路由器管理的网络。它允许大量设备从 5G 中继发送和接收数据。
- 波束成形(Beamforming)——另一种从无线网络世界借来的技术，使 5G 中继能够将数据流引导至网络设备的位置。该技术可最大限度地减少特定区域内不同网络和无线电波之间的干扰。
- 全双工(Full Duplex)- 允许 5G 中继上的天线以相同的频率同时发送和接收数据，而不是在发送和接收之间交替。
5G 网络希望连接更多设备
如您所见，5G 网络使用的一些技术起源于Wi-Fi网络，但它们适用于移动电信。这解释了 5G 与Wi-Fi 5标准或用于Wi-Fi的 5GHz 频率之间的混淆。您可以在这篇文章中找到有关无线网络标准的更多信息：什么是 Wi-Fi 6、Wi-Fi 5 等？(What is Wi-Fi 6, Wi-Fi 5 and so on?)
如果您想了解更多有关 5G 移动网络的信息，我们推荐由IEEE Spectrum制作的视频- 最大的工程和应用科学出版物：
5G是谁发明的？
5G“标准”不是一家公司发明的。这是几家公司在第三代合作伙伴项目(Generation Partnership Project)(3GPP) 的保护伞下合作的结果——这是一个负责开发标准和电信协议的联盟。该联盟包括来自美国、欧洲(Europe)、日本(Japan)、中国(China)、印度(India)和韩国(South Korea)的公司。
我为什么要关心 5G？5G 网络有什么好处？
目前，5G 网络的好处更多的是理论而非实际。这是因为移动运营商需要很多年才能在其国家建立完整的 5G 基础设施。在接下来的几年中，我们将主要拥有 4G 网络和 5G 功能。只有在繁忙的市区，我们才会拥有相对“完整”的5G网络。例如，欧盟(European Union)计划在 2025 年之前在其所有主要城市和主要交通路线上实现不间断的 5G 覆盖。您可以在欧洲 5G 行动计划(Europe’s 5G Action Plan)中找到有关此主题的更多详细信息。此外，(States)美国(United) 商务部在其实施计划(implementation plan)中宣布5G将成为21世纪国家繁荣与安全的主要因素之一，并将成为一项战略投资。
更高的数据传输速度
5G 网络的所有用户的主要好处是提高了速度。在典型的 4G 网络中，全球平均速度为 25 Mbps。在拥有稳固 4G LTE(LTE)基础设施的城市地区，速度会增加到 200 到 500 Mbps之间。使用 5G，速度可以从 1 Gbps开始，最高可达 10 Gbps。这种速度是革命性的，可以与有线光纤网络竞争。想象一下(Imagine)，当智能手机或平板电脑通过电缆连接到 1 Gbps网络时，以与SmartTV相似的速度观看4K Netflix电影。(Netflix)
低延迟
据估计，5G 网络平均将提供 10 毫秒到 1 毫秒之间的延迟，这是对 4G 网络提供的 50 毫秒的显着改进。在许多用例中，减少延迟将是一个重要的好处，例如远程医疗（通过人们控制的机器人远程进行的医疗程序）、互连的自动驾驶汽车、工业环境中的物联网(IoT)设备等等。
对于玩许多在线游戏的游戏玩家来说，减少延迟也是一个显着的好处。在乘公共汽车(Fortnite)上大学时在智能手机上畅玩《堡垒之夜》怎么样？
更有趣的是，一些专家表示，由于 5G 及其减少的延迟，实时投注服务将爆炸式增长。我也在考虑投资股票的人，以及他们如何能够更快地实时响应变化。那你呢？
更多设备连接到互联网
每年我们都有越来越多的设备需要互联网连接。这意味着现有的 4G 网络变得更加繁忙和缓慢。5G 允许连接到网络的设备数量激增，因为它可以支持 4G 网络的 100 倍以上。
(Less)连接设备使用的能源更少
5G 网络比 4G 网络更高效。这使得移动电话和与其连接的其他设备可以使用更少的能源进行数据传输。这意味着延长所有用户的电池寿命，尤其是如果他们的 iPhone 电池容量较小。🙂
5G智能手机贵吗？
最受欢迎的 5G 设备是智能手机。一开始，5G 支持只提供给大多数人买不起的高端、昂贵的智能手机。今天，我们拥有越来越多价格实惠的 5G 智能手机。最近的一个例子是realme 8 5G - 价格约为 280 美元或 229欧元(Euros)- 这是许多人可以承受的价格。
realme 8 5G使用的包装
除了实惠的价格外，realme 8 的 5G 版本看起来不错，并且它提供的硬件性能优于同型号的 4G 版本。5G 智能手机通常就是这种情况，因为它们需要比 4G 型号更新的处理器和芯片。

What are 5G and its benefits? What 5G smartphones are available? -
All the smartphone manufacturеrs and mobile operators are talking about 5G and its mаny benefits. We see more and more advertisements about how great 5G is and why you should have it. But why is that? Even anti-vaxxers are obsessing about 5G, not just govеrnments or smartphone manufacturers. In this article, we explain what 5G is, what 5G means, and which its bеnefіts are:
What is 5G? What does 5G mean?
5G doesn’t come from 5 GHz, 5 Gigabits, or five chips we’re injected with through vaccines. 🙂 Joke aside, 5G only means the fifth generation of mobile telecommunications. Just as 4G was the fourth generation, 3G was the third, and so on.
5G is not just one technology that is implemented a certain way, but a collection of telecommunications technologies that add up to a 5G network together. The main technologies that compose a 5G infrastructure are:
- Millimeter waves - the frequencies or the radio waves through which devices communicate through a network. In the case of a 5G network, there are many more of these available compared to 4G, but they are also more easily absorbed by walls, buildings, or weather events like rain or snow.
- Small cells - interconnected relays that transmit the radio waves used for 5G connections. In urban areas, 5G networks require a higher density of relays for data transmission.
- Massive MIMO - an adaptation of the MIMO technology found in Wi-Fi networks like the one managed by your home router. It allows a large number of devices to send and receive data from a 5G relay.
- Beamforming - another technology borrowed from the world of wireless networks that enables 5G relays to direct dataflows towards the location of network devices. This technology minimizes interference between the different networks and radio waves in a specific area.
- Full Duplex - allows the antennas on a 5G relay to send and receive data simultaneously on the same frequency instead of alternating between sending and receiving.
5G networks want to connect even more devices
As you can see, some of the technologies used by 5G networks have their roots in Wi-Fi networks, but they were adapted to mobile telecommunications. This explains the confusion between 5G and the Wi-Fi 5 standard or the 5GHz frequencies used for Wi-Fi. You can find more information about wireless networking standards in this article: What is Wi-Fi 6, Wi-Fi 5 and so on?
If you want to know more about 5G mobile networks, we recommend this video made by the IEEE Spectrum - the largest publication dedicated to engineering and applied sciences:
Who invented 5G?
The 5G “standard” was not invented by one company. It is the result of the collaboration between several companies, under the umbrella of the 3rd Generation Partnership Project (3GPP) - a consortium that takes care of developing standards and telecommunications protocols. This consortium includes companies from the US, Europe, Japan, China, India, and South Korea.
Why should I care about 5G? What benefits do 5G networks offer?
For now, the benefits of 5G networks are more theoretical than practical. This is because it will take many years for mobile operators to build a complete 5G infrastructure in their countries. In the next couple of years, we will have mostly 4G networks mixed with 5G capabilities. Only in busy urban areas, we are going to have relatively “complete” 5G networks. For example, the European Union plans to have uninterrupted 5G coverage in all its major cities and its main transport routes until 2025. You can find more details about this subject in Europe’s 5G Action Plan. Also, the department of commerce of the United States declares in its implementation plan that 5G will become one of the main factors in the country’s prosperity and security in the 21st century and that it is going to be a strategic investment.
Higher data transmission speeds
The main benefit for all users of 5G networks is increased speed. In a typical 4G network, the average speed at a global level is 25 Mbps. In urban areas with solid 4G LTE infrastructure, the speed increases to somewhere between 200 and 500 Mbps. With 5G, speeds can start at 1Gbps and reach up to 10 Gbps. Such speeds are revolutionary and compete with wired fiber-optic networks. Imagine watching a Netflix movie in 4K on a smartphone or tablet at a speed that’s similar to your SmartTV when it is connected through a cable to a 1 Gbps network.
Low latency
It is estimated that 5G networks are going to offer, on average, a latency between 10 ms and 1 ms - a significant improvement on the 50 ms offered by 4G networks. Reduced latency will be an essential benefit in many use-cases, like telemedicine (medical procedures made remotely, through robots that people control), interconnected self-driving cars, IoT devices from industrial environments, and so on.
Reduced latency is also a significant benefit for gamers who play many online games. What about playing Fortnite without lag on your smartphone while riding the bus to college?
To make things even funnier, some experts say that real-time betting services will explode due to 5G and its reduced latency. I’m also thinking about people who invest in stocks and how they will be able to respond faster to changes in real-time. What about you?
More devices connected to the internet
Each year we have more and more devices that require an internet connection. This means that existing 4G networks get busier and slower. 5G allows for an explosion of the number of devices that get connected to the network, as it can support 100 times more than 4G networks.
Less energy used by connected devices
5G networks are more efficient than 4G ones. This allows mobile phones and other devices connected to them to use less energy for data transmission. This means increased battery life for all users, especially if they have an iPhone with a small battery. 🙂
Does a 5G smartphone cost a lot?
The most popular 5G devices are smartphones. In the beginning, 5G support was offered only for premium, expensive smartphones that most people can’t afford. Today, we have more and more 5G smartphones with accessible prices. A recent example is realme 8 5G - which costs about 280$ or 229 Euros - a price that many can afford.
The packaging used for realme 8 5G
Alongside the affordable price, the 5G variant of realme 8 looks good, and it offers hardware that performs better than the 4G variant of the same model. This is often the case for 5G smartphones, as they need newer processors and chips than 4G models.
