信息技术系统间远程通信和信息交换局域网和城域网特殊要求第15-4部分:低速率无线个域网(WPAN)的无线媒体访问控制(MAC)和物理层(PHY)规范
ISO/IEC/IEEE 8802-15-4:2018 defines the physical layer (PHY) and medium access control (MAC) sublayer specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices with no battery or very limited battery consumption requirements. In addition, the standard provides modes that allow for precision ranging. PHYs are defined for devices operating various license-free bands in a variety of geographic regions.
