Description / Abstract:
This standard 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. Physical layers (PHYs) are defined for devices operating
various license-free bands in a variety of geographic regions.
Purpose
The standard provides for ultra low complexity, ultra low cost,
ultra low power consumption, and low data rate wireless
connectivity among inexpensive devices. In addition, one of the
alternate PHYs provides precision ranging capability that is
accurate to one meter. Multiple PHYs are defined to support a
variety of frequency bands.
