1. A wireless sensor monitoring system at an asset location, comprising:
- a satellite modem;
a first wireless device that interfaces with said satellite modem for delivery of sensor data to a remote location; and
a second wireless device that is coupled to a sensor, said second wireless device being configured to receive data from said sensor, said second wireless device being configured to enter into a low power state and awaken at a scheduled time at which said first wireless device also wakes from a low power state.

Abstract
A system and method for implementing a low-power local-area wireless network for use with a mobile terminal satellite modem. This low-power local-area wireless network enables sensors on an asset to wirelessly transmit sensor data to a mobile terminal affixed on the asset. The mobile terminal reports the sensor data along with asset position information to a centralized facility via a communications satellite.
