The transmission system combines a self-contained, wireless seismic acquisition unit and a wireless, line-of-site, communications unit to form a plurality of individual short-range transmission networks and also a mid-range line-of-site transmission network. Each seismic unit has a power source, a short-range transceiver and a geophone disposed within a casing. Each wireless communications unit is formed of an elongated support structure on which is mounted an independent power source, mid-range radio transceiver and a short-range transceiver configured to wirelessly communicate with the short-range transceiver of the acquisition unit. Preferably, the acquisition unit is buried under the ground surface, while the wireless communications unit is positioned adjacent in the near vicinity of the buried unit and vertically protrudes above the ground. The acquisition unit and the wireless communications unit communicate by short-range transmissions, while the wireless communications unit communicates with other seismic acquisition systems using mid-range radio transmission.
