1. A method for wireless communication in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- generating a traffic slot map, the traffic slot map indicating a first number of slots of a traffic channel cycle that will be transmitted at a first data rate, a second number of slots of the traffic channel cycle that will be transmitted at a second data rate, and one or more hashing parameters, the traffic slot map to be used by one or more M2M devices to allow each of the one or more M2M devices to identify at least one time slot within the traffic channel cycle having data intended for the identifying M2M device; and
broadcasting the traffic slot map to the one or more M2M devices.

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.
