Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A packet is decoded and demodulated by an M2M device that is received during a time slot of a physical layer forward link frame in the M2M wireless WAN. The packet is transmitted by a base station. The M2M device enters a sleep state before a physical layer acknowledgment (ACK) message is transmitted to the base station to indicate receipt of the packet.

Abstract: Methods, systems, and devices are described for tracking an asset or person using a synchronized set of anchor units. A tag attached to the asset or person has a clock offset relative to the anchor units, which in turn have clock offsets relative to each other. To remove the effect of the clock offset from the tag when estimating the location of the tag, the anchor units are synchronized by determining their clock offsets through signals wirelessly transmitted between the anchor units. The clock offsets may be obtained when there is a clear line-of-sight (LOS) path between anchor units as well as when the LOS path is obstructed. The range measurements that produce the estimate of the location of the tag are then determined from preamble information provided by the tag and from the clock offsets determined for the anchor units.
