IEEE Draft Standard for Local and metropolitan area networks--Part 15.4: Low-Rate Wireless Personal Area Networks (LR-WPANs) Amendment for an Ultra Low Power Physical Layer

This amendment specifies two alternate PHYs, TASK and RS-GFSK, in addition to those of IEEE Std 802.15.4-2011. The amendment also defines those MAC modifications needed to support their implementation. The alternate PHYs enable low cost, ultra-low power consumption, and extended battery life, in various frequency bands and geographical regions under multiple regulatory domains.
