1. A method for adaptive allocation of multiplexing signatures comprising unique frequencies to a wireless module in a seismic data acquisition system, the method comprising:

  • first scanning with a first wireless module in the seismic data acquisition system to measure a received signal strength on each of a plurality of frequencies during each of a plurality of transmission time periods, wherein the plurality of transmission time periods each correspond to a different time period to which a unique frequency is to be assigned to define a multiplexing sequence through which the first wireless module repetitively progresses during transmission of data from the wireless module; and

    first selecting for each of the plurality of transmission time periods at the first wireless module a different respective one of the plurality of frequencies, wherein the selecting is based on the first scanning, and wherein the first selecting includes assigning a selected frequency to each time period of the multiplexing sequence to define the multiplexing sequence, andfirst transmitting data from the first wireless module by progressing repetitively through each of the plurality of transmission time periods using the assigned frequency for each of the plurality of transmission time periods of the multiplexing sequence of the first wireless module.
