CPC G01V 1/223 (2013.01) [H04B 7/2643 (2013.01); H04L 27/2601 (2013.01)] | 6 Claims |
1. A system having wireless seismic sensor nodes for reflection seismic survey in a wireless seismic network within a survey area, each of a plurality of the wireless seismic sensor nodes comprising:
communications circuitry configured to detect seismic reflection signals from a seismic energy source;
a memory for recording the detected seismic reflection signals; and
the communications circuitry configured to transmit the recorded seismic reflection signals as seismic digital data, using a combination of Orthogonal Frequency-Division Multiple Access (OFDMA) and Time Division Multiple Access (TDMA), to a central data receiving device, wherein
the detecting, recording and transmitting is repeated substantially a plurality of times upon changing the source location for the seismic reflection signals,
wherein each seismic sensor node of the plurality of wireless seismic sensor nodes is a a ground motion sensor that converts ground vibrations into an output voltage.
