A Holistic Approach to Addressing the Unrelenting Efficiency and Linearity Challenges of 5G Transmitters

无线连接以疯狂的速度发展，从站到站的通信（数千个连接），通过站到人的模式（数百万个连接），到目前的人与人的连接（数十亿个连接）。令人难以置信的是，连接需求的增长已经得到了无线通信的相对渐进式进步的满足，并在我们目前的第四代（4G）技术中达到顶峰。然而，这项技术将不再足以满足日益增长的连接需求。在未来十年中，数万亿台设备将实现人与人、人与物、物与物的连接，将熟悉的物品变成具有内置传感和网络功能的所谓智能物体，并将无线连接推向万亿级。第五代（5G）无线技术将需要全新的无线设备、通信基础设施和网络来应对前所未有的挑战，包括100-1000倍的系统容量、高达每秒千兆字节的数据吞吐量、1毫秒的延迟以及10倍的设备电池寿命，同时降低成本和功耗。

Wireless connectivity has advanced at a frenetic rate, building from station-to-station communication (thousands of connections), through station-to-people modalities (millions of connections), to the current people-to-people connectivity (billions of connections). Incredibly, the rise in connectivity needs has been met with relatively incremental advances in wireless communication, culminating in our current fourth generation (4G) technology. However, this technology will no longer suffice to meet increasing connectivity demands. In the next decade, trillions of devices will connect people-to-people, people-to-things and things-to-things – turning familiar items into so-called smart objects with built-in sensing and networking capabilities, and propelling wireless connectivity to the tera-scale. Fifth-generation (5G) wireless technologies will require completely new wireless devices, communication infrastructure and networks to meet the unprecedented challenges, which include 100-1000 times higher system capacity, data throughput of up to gigabytes per second everywhere, latency down to 1 millisecond, and 10 times longer device battery life, while lowering cost and power consumption.
