1. A condition monitoring system for monitoring operation of a peripheral asset, said condition monitoring system comprising:
- a first node device comprising a radio having a radio power level that is adjustable, a processor, a memory coupled to the processor, and one or more executable instructions stored on the memory and configured to be executed by the processor to adjust the radio power level for the radio, the executable instructions comprising instructions for,receiving a first signal from a second node device via the radio;
measuring a signal strength for the first signal; and
adjusting the radio power level in accordance with a pre-determined criteria relating the signal strength of the first signal to a value for the radio power level that requires the least amount of power necessary for the first node device to communicate with the second node device.

Abstract
This disclosure describes examples of condition monitoring systems with node devices that can adjust the power level of a radio. Embodiments of the node device can dynamically vary the power level for the radio in response to communication with other node devices. In one example, the node devices measure the strength of a signal received from the other node devices. The node devices can, in response to this value, vary the power level of the radio to optimize power consumption and extend the battery life for the node device.

11. A method for reducing power consumption in node devices of a condition monitoring system, said method comprising:
at a mesh network comprising a first node device and a second node device, each comprising a radio, a processor, and memory; receiving a first signal from the second node device via the radio at the first node device; measuring a signal strength for the first signal at the first node device; and adjusting the radio power level at the first node device in accordance with a pre-determined criteria relating the signal strength for the first signal to a value for the radio power level at the first node device that requires the least amount of power necessary for the first node device to communicate with the second node device. - View Dependent Claims (12, 13, 14)

15. A method to prolong battery life in node devices of a condition monitoring system, said method comprising:
-
at a first node device comprising a radio, a processor, and memory; transmitting a signal to a second node device; receiving a signal from the second node device in response to the transmitted signal; measuring a signal strength for the received signal; comparing the signal strength to a threshold; and setting a value of the radio power level so the signal strength for the received signal falls between an upper boundary and a lower boundary defined by the threshold, wherein the value of the radio power level requires the least amount of power necessary for the first node device to communicate with the second node device. - View Dependent Claims (16, 17, 18, 19, 20)
