backhaul connection
回程连接
Access points and computing devices may establish a wireless connection using any of a variety of air interface technologies, including for example wireless local area network (WLAN) technologies (e.g., Wi-Fi, etc.), cellular technologies (e.g., Third Generation (3G), Fourth Generation (4G), Long Term Evolution (LTE), etc.), and personal area network (PAN) technologies (e.g., Bluetooth, etc.). Access points may connect to a router and/or other networking hardware (singularly or in various networked configurations) to establish connections to the Internet via a core network providing Internet connectivity. The connection of the access point to the Internet may be referred to as a backhaul connection. When the access point has a backhaul connection, the connection between the access point and a computing device provides the computing device with Internet access. When the access point does not have a backhaul connection, even though the access point and a computing device may have established a connection, Internet access is not provided to the computing device.
[回]程网络主要承担核心网和接入网之间的通信任务，是基站控制器和基站之间的信息传输网络。在5G网络中，为了应对流量的爆炸性增长，Femtocell、Picocell、Microcell等小基站的部署会具有超密集、随机等特点，使得为小基站提供费用低、高质量的回程连接成为一种挑战。
