本文概述了在电视白色空间（TVWS）中运行的第一个低速率（LR）无线个域网（WPAN）IEEE 802.15.4m的形成背后的动机和过程。有三个主要的力量推动LR-WPAN社区将其操作频带扩展到TVWS。首先，开放新频谱资源的TVWS相关法规的变化是关键触发因素。其次，存在由LR-WPAN系统解决的许多潜在应用，这些应用预计将受益于频谱的扩展。第三，在相同的常规频带中针对相同类型的应用的多个配置的出现，表明潜在的拥塞和异构共存问题，也是主要的推动因素之一。在本文中，不同的法规，潜在的使用模式和传统的LR-WPAN系统之间的相互作用的列表进行了全面的总结。给出了关于这些因素如何到位以实现IEEE 802.15.4m的形成的一般讨论。最后，本文总结了IEEE 802.15.4m系统的预期功能需求。
This paper provides an overview on motivations and process behind the forming of the first low rate (LR) wireless personal area networks (WPAN) operating in the TV white space (TVWS), IEEE 802.15.4m. There are three main forces driving the LR-WPAN community to expand its operational band to the TVWS. First, the change in TVWS-related regulations that opens up new spectrum resources is the key triggering factor. Secondly, there are many potential applications addressed by LR-WPAN systems that are anticipated to benefit from the expansion of the spectrum. Thirdly, the emergence of multiple standardizations targeting on the same types of applications in the same conventional frequency bands, indicating potential congestion and heterogeneous coexistence issues, is also one of the main pushing factor. In this paper, a comprehensive summary of different regulations, list of potential usage models and interactions among conventional LR-WPAN system are presented. A general discussion on how these factors fall in place to realize the forming of IEEE 802.15.4m is given. Finally, the paper concludes with expected functional requirements for the IEEE 802.15.4m system.
