5 days ago · The IEEE 802.15.4-2003 standard has been superceded by the publication of IEEE 802.15.4-2006. The new standard can be purchased from the IEEE store. The TG4 task group put itself into hibernation at the March 2004 meeting after forming a task group (TG4b).
Mar 23, 2017 · In this amendment to IEEE Std 802.15.4TM-2011, a physical layer for IEEE 802.15.4 in the 2360 MHz to 2400 MHz band which complies with Federal Communications Commission (FCC) MBAN rules is defined. Modifications to the MAC needed to support this new physical layer are also defined in this amendment.
The IEEE 802.15.4 standard specifies the MAC and PHY layers of Low-Rate Wireless Personal Area Networks (LR-WPANs) [ 1 ]. The IEEE 802.15.4 MAC and PHY layers provide the basis of other higher-layer standards, such as ZigBee, WirelessHart®, 6LoWPAN and MiWi. Such standards find application in home automation and sensor networking and are ...
2. IEEE 802.15.4 is a low-data rate wireless personal area network and is the PHY and MAC layer used by many IoT protocols, such as ZigBee, and WirelessHART. 3.802.15.4 uses full function and reduced function devices. FFDs can act as coordinator.

An interpretation of IEEE Std 802.15.4-2006, 6.8.2.5 and 6.8.3.2 is requested. While the BPSK PHY and the ASK PHY of the 868 MHz specifications use raised-co-sine and root-raised-cosine pulse shape filtering to represent the baseband chips, the O-QPSK PHY uses half-sine pulse shaping for baseband-chip representation (see 6.8.2.5).
