Method and system for transmission of seismic data
First Claim
1. A transmission method for seismic data acquisition units, comprising:
- deploying a seismic data acquisition unit comprising a first short-range transceiver and a geophone;
deploying a wireless communication unit comprising a first radio transceiver and a second short-range transceiver configured to wirelessly communicate with the first short-range transceiver;
establishing, using the first short-range transceiver and the second short-range transceiver, a wireless magnetic link between the wireless communication unit and the seismic data acquisition unit utilizing magnetic signals; and
establishing a wireless radio link between the wireless communication unit and a second wireless communication unit utilizing multiplexed radio signals, the wireless radio link different than the wireless magnetic link.

Abstract
The transmission system combines a self-contained, wireless seismic acquisition unit and a wireless, line of site, communications unit to form a plurality of individual short-range transmission networks and also a mid-range, line of sight transmission network. Each seismic unit has a power source, a short-range transmitter/receiver disposed within a casing and a geophone disposed within the casing. Each wireless communications unit is formed of an elongated support structure on which is mounted an independent power source, mid-range radio transmitter/receiver; and a short-range transmitter/receiver configured to wirelessly communicate with the short-range transmitter/receiver of the acquisition unit. Preferably, when deployed, the acquisition unit is buried under the surface of the ground, while the wireless communications unit is positioned in the near vicinity of the buried unit so as to vertically protrude above the ground. The acquisition unit and the wireless communications unit communicate by short-range transmissions, while the wireless communications unit communicates with other seismic acquisition systems using mid-range radio transmission. When multiple seismic acquisition unit/wireless communications units are deployed in an array, the system can pass collected seismic and quality control data in relay fashion back to a control station and/or pass timing and control signals out to the array.
