A survey data acquisition system acquires survey data regarding a subterranean structure. Information is wirelessly communicated between a wireless survey receiver and a wireless concentrator. The wireless communication uses a wireless protocol based on a WiFi communications technology, where the wireless protocol employs time division multiplexing in which a larger number of time slots are assigned for uplink communication from the wireless survey receiver to the wireless concentrator than for downlink communication from the wireless concentrator to the wireless survey receiver.
