Abstract:
1. A seismic data acquisition apparatus comprising: a seismic sensor deployed at a seismic sensor location that is configured to: i) listen for an open time slot and frequency, and ii) request the use of the open slot; a base station having a plurality of diversity antennas, the base station being configured to respond to the sensor request by reducing an overall data rate when operating at full capacity; and a steerable antenna coupled to the base station wherein the steerable antenna is configured to receive a sensor signal from the seismic sensor location, monitor a strength of the received sensor signal, and determine a direction of the seismic sensor location from the strength of the received signal to steer the steerable antenna, wherein the seismic sensor is configured to capture the open slot and transmit to the base station when the base station is not operating at full capacity, and wherein the base station is configured to select an optimum diversity antenna for transmission.
