Abstract
Systems and methods are provided for acquiring seismic data using a wireless network and a number of individual data acquisition modules that are configured to collect seismic data and forward data to a central recording and control system. In one implementation, a number of remote modules are arranged in lines. Base station modules receive information from the lines and relay the information to a central control and recording system. Radio links operating on multiple frequencies are used by the modules. Dynamic multiplexing technique may include advancing one or more modules in a seismic array through a multiplexing signature sequence in successive transmission periods. The multiplexing signature sequence may be random or pseudo-random. A shared multiplexing signature sequence may be used at all the modules in the seismic array. Modules belonging to a common collision domain may operate out of phase with respect to the shared multiplexing signature sequence.
