Seismic data acquisition using time-division multiplexing
First Claim
1. A method of transmitting data wirelessly between a remote unit and a plurality of field service units (FSUs) placed over a region of interest, each field service unit (FSU) acquiring seismic data from at least one seismic receiver in a plurality of seismic receivers placed in the region of interest, the method comprising:
- specifying a data transmission time period for transmission of data between the remote unit and each FSU in the plurality of FSUs;
dividing the data transmission time period into a plurality of time slots, each time slot having a fixed time length; and
transmitting data according to a selected mode of utilizing the data transmission time period, the selected mode including transmitting data from the remote unit to at least one FSU during at least one of the time slots and transmitting an unsolicited message relating to a condition of the seismic data acquisition from at least one FSU to the remote unit during at least one another time slot.

Abstract
A method of transmitting data between a remote unit and a plurality of field service units placed over a region of interest, each field service unit acquiring seismic data from at least one seismic receiver in a plurality of seismic receivers placed in the region of interest is provided that, in one aspect, may include: specifying a data transmission time period having a fixed continuous time length for transmission of data between the remote unit and each field service unit; dividing the data transmission time period into a plurality of time slots, each time slot having a fixed time length; and transmitting data from the remote unit to each field service unit during at least one of the time slots and from each field service unit to the remote unit during at least one another time slot. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

7. An apparatus configured to acquire seismic data from at least one sensor deployed at a field location, comprising:
-
a data storage device that includes a specified data transmission time period having a fixed continuous time length for transmission of data between a remote unit and the apparatus, wherein the data transmission time is further divided into a plurality of time slots, each time slot having a fixed time length; and a processor configured to access the data storage device according to a selected mode of utilizing the data transmission time period to receive data from a remote unit during a first particular time slot and transmit an unsolicited relating to a condition of the seismic data acquisition to the remote unit during a second particular time slot. - View Dependent Claims (8, 9, 10, 11)
