Abstract
Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). An operating frequency band of the M2M wireless WAN is divided into at least a first frequency channel and a second frequency channel. The first and second frequency channels being used for communications on a reverse link. A first rise over thermal (RoT) threshold is set for the first frequency channel. A second RoT threshold is set for the second frequency channel. The second RoT threshold is lower than the first RoT threshold.

A method for wireless communication in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- dividing an operating frequency band of the M2M wireless WAN into at least a first frequency channel and a second frequency channel, the first and second frequency channels being used for communications on a reverse link;
- setting a first rise over thermal (RoT) threshold for the first frequency channel;
- and
- setting a second RoT threshold for the second frequency channel, the second RoT threshold being lower than the first RoT threshold.
A base station configured for wireless communication in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions being stored in the memory, the instructions being executable by the processor to:
- divide an operating frequency band of the M2M wireless WAN into at least a first frequency channel and a second frequency channel, the first and second frequency channels being used for communications on a reverse link;
- set a first rise over thermal (RoT) threshold for the first frequency channel;
- and
- set a second RoT threshold for the second frequency channel, the second RoT threshold being lower than the first RoT threshold.
An apparatus configured for wireless communication in a machine-to-machine (M2M) wireless Wide Area Network (WAN), comprising:
