Full Description

Scope

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.

Abstract

Amendment Standard - Active.A physical (PHY) layer enabling the use of the 865 MHz to 867 MHz band in India is defined in this amendment. The supported data rate should be at least 40 kb/s and the typical line-of-sight range should be on the order of 5 km using an omnidirectional antenna. Included are any channel access and/or timing changes in the medium access control necessary to support this PHY layer.
