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.
