5G (5th generation mobile networks

5G (5th generation mobile networks or 5th generation wireless systems) denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G has speeds beyond what the current 4G can offer.

The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks:

Data rates of several tens of megabits per second should be supported for tens of thousands of users
1 gigabit per second to be offered simultaneously to many workers on the same office floor
Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments
Spectral efficiency should be significantly enhanced compared to 4G
Coverage should be improved
Signalling efficiency should be enhanced
Latency should be reduced significantly compared to LTE[1]
The Next Generation Mobile Networks Alliance feels that 5G should be rolled out by 2020 to meet business and consumer demands.[2] In addition to providing simply faster speeds, they predict that 5G networks also will need to meet the needs of new use cases, such as the Internet of Things as well as broadcast-like services and lifeline communication in times of natural disaster.

Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities are still being grouped under the current ITU-T 4G standards.

5G（第五代移动网络和第五代无线系统）是指移动通信标准的下一个重要阶段超越目前的4G / IMT-Advanced标准。5G有速度超出目前的4G可以提供。

下一代移动网络联盟定义的以下要求：

5G网络对几十兆比特每秒的数据传输速率应为用户
1千兆每秒数以千计可同时提供许多工人在同一办公楼
数百成千上万的并发连接的是大量的传感器部署
频谱效率支持数十支应该显著高于4G
覆盖应改进的
信令效率应该增强
延迟应大大减少相比，LTE [ 1 ]
的下一代移动网络联盟认为，5G应该推出2020满足企业和消费者的需求。[ 2 ]除了提供简单的更快的速度，他们预测，5G网络也需要满足新的使用案例的需要，如物联网以及广播服务和在自然灾害时期的生命线的通信。

虽然更新标准定义的能力超过目前的4G标准定义了在考虑，这些新的能力仍然被分组目前ITU-T 4G标准下。
