Method and system for transmission of seismic data
DCFirst Claim
1. A method for seismic data transmission comprising the steps of:
- A. providing a plurality of seismic acquisition units, wherein each of said seismic acquisition units is capable of acquiring seismic data, receiving a short range radio transmission and transmitting a short range radio transmission;
B. utilizing a at least two of said seismic acquisition units to transmit seismic data via short range radio transmission to another seismic acquisition unit in the array;
C. utilizing a at least two of said seismic acquisition units to receive seismic data via short range radio transmission from another seismic acquisition unit in the array;
D. partitioning said plurality of seismic acquisition units into at least two sub-sets of seismic acquisition units; and
E. using a short range radio transmission technique having parameters set so that non-interfering radio transmission may be effected in each sub-set.

Abstract
The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path. Utilizing an array of seismic units permits transmission routes back to a control station to be varied as needed. In transmissions from the most remote seismic unit to the control station, each unit within a string receives seismic data from other units and transmits the received seismic data along with the receiving unit'"'"'s locally stored seismic data. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array.
