Task Group 4md (TG4md)
Revision to IEEE
WPAN Home Page
The standard provides for
ultra low complexity, ultra low cost, ultra low power consumption, and
low data rate wireless connectivity among inexpensive devices,
especially targeting the communications requirements of what in now
commonly referred to as the Internet of Things. In addition, some of
the alternate PHYs provide precision ranging capability that is
accurate to one meter. Multiple PHYs are defined to support a variety
of frequency bands.
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. PHYs are defined for devices operating in
various license-exempt and other bands in a variety of geographic
There are a number
errors, inconsistencies, and ambiguities in need of correction.
Additionally there will be six completed amendments during the course
of the revision that should be rolled up. These are 802.15.4n,
802.15.4q, 802.15.4s, 802.15.4t, 802.15.4u, and 802.15.4v.
