Patent ID: 7869444

Claim:
A data acquisition network, comprising: at least one first wireless network of seismic sensors having a radio-type data transmission protocol, wherein each seismic sensor of the first wireless network has sends and receives data by wireless link by radio waves having the radio-type data transmission protocol, wherein two neighboring seismic sensors of the first wireless network transmit data between them which are conveyed by the radio waves having the radio-type data transmission protocol, at least second network of seismic sensors having the radio-type data transmission protocol, wherein each seismic sensor of the second network has sends and receives data also conveyed by radio waves having the radio-type data transmission protocol by cable, wherein two neighboring seismic sensors of the second network transmit data between them by radio waves having the radio-type data transmission protocol by means of a cable, wherein the at least second network forms a cabled network of seismic sensors, wherein the second cabled network comprises a seismic sensor comprising means to send and receive data by a wireless link and by a cable link using both radio waves having the radio-type data transmission protocol for performing a relay transmitting the data by the radio waves having the radio-type data transmission protocol between the second cabled network and the first wireless network, wherein the first wireless network of seismic sensors and the second cabled network of seismic sensors have the same radio-type data transmission protocol; wherein the radio waves of the first wireless network are the same as the radio waves of the second cabled network.
