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.

Claims

1-44. -44. (canceled)

45. A method of performing seismic exploration, comprising:

providing a self-contained wireless seismic acquisition unit at a first location, the self-contained wireless seismic acquisition unit including a first transceiver and a geophone;

providing a wireless communications unit at a second location, the wireless communications unit configured to communicate with the self-contained wireless seismic acquisition unit and including a support structure, a power source, a second transceiver configured to wirelessly communicate with the first transceiver, and a third transceiver;

wirelessly coupling the seismic acquisition unit with the wireless communications unit to create a first transmission path between the seismic acquisition unit and the wireless communications unit;

receiving, by the third transceiver, a control signal;

adjusting, by the wireless communications unit, the control signal to provide an adjusted control signal for transmission between the wireless communication unit and the seismic acquisition unit; and

transmitting, via the first transmission path, the adjusted control signal from the second transceiver to the first transceiver.

46. The method of claim 45, comprising:

the second transceiver including short-range transmission capabilities; and

the third transceiver including mid-range transmission capabilities.

47. The method of claim 46, wherein the second transceiver and the third transceiver are a same transceiver, comprising:

toggling the same transceiver between mid-range transmission capability and short-range transmission capability.

48. The method of claim 45, comprising:

at least partially burying the self-contained wireless seismic acquisition unit below a surface of a ground.

49. The method of claim 45, comprising:

deploying a plurality of seismic acquisition units and a plurality of wireless communications units to form an array.

50. The method of claim 45, comprising:

deploying a plurality of seismic acquisition units and a plurality of wireless communications units to form an array, each of the plurality of seismic acquisition units capable of wirelessly coupling to at least one of the plurality of wireless communications units.

51. The method of claim 45, comprising:

deploying a transmission station to communicate with the wireless communications unit; and

wirelessly coupling the transmission station with the wireless communications unit via a second transmission path comprising mid-range transmission capabilities.

52. The method of claim 45, comprising:

deploying a plurality of seismic acquisition units and a plurality of wireless communications units to form an array, each of the plurality of seismic acquisition units configured to wirelessly couple with at least one of the plurality of wireless communications units; and

deploying a transmission station configured to communicate with at least one of the plurality of wireless communications units.

53. The method of claim 52, comprising:

identifying a plurality of transmission paths between the transmission station and at least one of the plurality of wireless communications units.

54. The method of claim 45, wherein the transceiver and the geophone are housed within a case of the wireless seismic acquisition unit.

55. The method of claim 45, comprising:

deploying the wireless communications unit at the second location within 50 feet of the first location.

56. The method of claim 45, wherein the support structure is an elongated support structure, comprising:

at least one of the second transceiver and the third transceiver mounted on the elongated support structure.

57. The method of claim 45, comprising:

receiving, by the third transceiver, the control signal via a wireless network with mid-range transmission capabilities.

58. The method of claim 45, wherein the first transmission path comprises short-range transmission capabilities.

59. The method of claim 45, wherein the control signal comprises a timing signal.

60. The method of claim 45, wherein the control signal comprises a timing signal, comprising:

disciplining a local clock of the seismic acquisition unit based on the timing signal.

61. The method of claim 45, comprising:

adjusting, by the wireless communications unit, a strength of the control signal to provide the adjusted control signal for transmission between the wireless communication unit and the seismic acquisition unit.

62. A system to perform seismic exploration, comprising:
