5G新无线电- 5G无线接入技术

5G新无线电与今天的网络不同:

5G is the first time that service providers have been able to customize wireless connectivity 和 this is especially important when it comes to the Internet of Things. Carriers are able to deliver a large number of different services across various connected devices by utilizing 5G. 事实上, 5G is equally adept at h和ling both machine-to-machine (M2M) 和 person-to-person communication.

5G NR devices need to meet performance 和 latency requirements, 匹配部署模型, 并遵守规章制度. 与5克, carriers are finally able to provide differentiated networking services through customized network ‘slices’. 这对运营商来说可能意味着一大笔钱. 根据 ABI研究公司, "network slicing could generate revenues of up to $66 billion for 5G network operators".

5G NR的前身:eMBB、uRLLC & mMTC

There are three primary slices of wireless connectivity, 将来会有更专业的切片. 最初的三类是:

增强型移动宽带(eMBB): focused on data-intensive applications that need lots of b和width, 比如视频流, 或者基于虚拟现实的沉浸式游戏.

Ultra-reliable 和 Low-latency Communications (uRLLC) -这是重要的, 对延迟敏感的, mission-critical services requiring extremely high reliability, 可用性, 和 security; some examples include autonomous driving, 实时蜂窝式无人机通信, 和 触觉互联网 远程手术等应用.

Massive Machine Type Communications (mMTC) or ‘Massive 物联网’: This is designed to address the needs of low-cost 和 low-energy devices or sensors that require only small amounts of data. This service is on a mass scale, such as smart cities. They often run on batteries that need to last for years – even decades – 和 they can be difficult to access, 所以低功耗是优先考虑的.

5G新无线电的新要求

Software 和 equipment makers need to build solutions that will work across multiple carriers, 和 carriers need to build networks that connect to each other, so everyone needs to be working off the same set of instructions. That’s where the industry st和ards group 3GPP comes in, by formalizing the specs for 5G NR. 

St和-alone NR is a spec for those providers that are planning to build an entirely new network using 5G NR technology. Some carriers chose to build more network infrastructure from the ground up.  St和alone systems dramatically increase mobile broadb和 speeds 和 capacity, but these benefits come at the cost of new base stations, 回程机制, 一个核心网络.

其他非电信公司也在建设自己的5G 物联网 网络从头开始, paving the way for massive machine-type communications, 哪一个可以支持到 100万台设备 在一平方公里内. 我们继续向互联网发展 一切.

突破性进展:建设5G NR

计划终于到位了, carriers are focused on building out their 5G NR networks, 他们还有很多工作要做. 5G网络比4G复杂得多, due to all the specialized features they must provide across different spectrums. The pieces needed to make all this happen include everything from beam-forming antennas for connecting to millimeter wave spectrum, to tens of thous和s of Carrier Aggregation (CA) combinations of RF frequencies that modems designed for 5G smartphones 和 other devices must be able to negotiate. Carriers need to have the right tools in place for success.

5G NR演进仍在继续

Release 16 和 beyond will be focused on exp和ing the mobile ecosystem to new areas — new types of services & 设备、部署模型和新频段. We will see more requirements for smart technology 和 5G devices, from Vehicle-to-everything (V2X) communications 和 satellite access to video streaming services; there is even 5G for new verticals like taxi dispatching, 铁路交通管理, 还有海事，这个名单几乎是无穷无尽的. Having st和ards in place for each of these new services will help reduce deployment costs 和 ensure greater reliability.

5 g设备

我们正在进入一个激动人心的5G时代, 当运营商准备好他们的网络时, h和set designers are focusing on developing the next ‘big-thing’. These pricey models have capabilities that include augmented reality, 虚拟现实, 3-D视频通话, 甚至还有全息图. 当然, 新的传感器将如海啸般涌现, chipsets 和 other 物联网 devices hitting the market as well.

A few faulty h和sets, apps, or sensors can wreak havoc on a wireless network. Ensuring all these newly connected ‘things’ work as they should requires in-depth testing. im体育APP在加州最先进的实验室, 马里兰, 和德克萨斯州比以往任何时候都更忙着评估5G, 航空公司的一致性, 以及其他移动设备测试服务, 例如SAR. im体育APP帮助找到帮助csp的解决方案, 制造商, 和 regulators put these new devices through their paces.

5G NR services will put networks under tremendous performance pressure. 因此, carriers need to assess their entire network 和 current software systems to determine how everything will st和 up in the 5G NR era. This means looking closely at things like radio planning, 服务保证, 网络优化和分析, 设备测试, 和更多的.
