Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A traffic slot map is generated. The traffic slot map identifies one or more first time slots and one or more second time slots. First data is transmitted during the one or more first time slots at a first data rate. Second data is transmitted during the one or more second time slots at a second data rate. The traffic slot map is broadcasted to one or more M2M devices during a traffic slot of a first forward link frame at a beginning of a traffic channel cycle.

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.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A first paging message is transmitted in the M2M wireless WAN according to a first paging cycle. An occurrence of a first event is detected. A second paging message is transmitted, based at least in part on the occurrence of the first event. The second paging message is transmitted according to a second paging cycle. The second paging cycle being different from the first paging cycle.

A first paging message is transmitted in the M2M wireless at a first data rate using a first paging channel. An occurrence of a first event is detected. A second paging message is transmitted, based at least in part on the occurrence of the first event. The second paging message is transmitted at a second data rate using a second paging channel.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). An event is detected that indicates a condition of a forward link in the M2M wireless WAN. A data rate is selected to transmit an acknowledgment (ACK) message. The selection of the data rate is based at least in part on the detected event that indicates the condition of the forward link. The ACK message is transmitted on the forward link in the M2M wireless WAN according to the selected data rate.
