摘要/Abstract

摘要：

随着网络技术的飞速发展,用户对家庭场景内网络体验的要求日益增加。FTTR能够在一定程度上解决无线网络连接不稳定的问题。在FTTR架构基础上,介绍了集中式光无线网接入架构,探讨了下一代Wi-Fi协同空间复用技术与速率控制的主要原理,并对当前面临的挑战以及未来的研究方向进行了分析和展望。

关键词: FTTR, 集中式光无线网接入架构, 协同空间复用

Abstract:

With the rapid development of network technology, users have higher requirements for their home network. Fiber to the room (FTTR) can solve the problem of an unstable wireless network. Based on the FTTR architecture, a centralized wireless-optical access network is introduced. Then, the main principles of coordinated spatial reuse technology and rate adaption for the next generation of Wi-Fi are discussed. Finally, the current challenges and future research directions are analyzed and prospected.

Key words: FTTR, centralized wireless-optical access network, coordinated spatial reuse
