Mobile body wireless communication performance estimation system and method

A mobile body wireless communication performance estimation method for estimating wireless communication performance of a mobile body relative to respective access points, the mobile body wireless communication performance estimation method comprising:

• a radio wave strength measuring step of measuring radio wave strength of a packet wirelessly communicated mutually between any of the access points and the mobile body;
• a first threshold determining step of determining whether or not each radio wave strength measured in the radio wave strength measuring step is equal to or more than a first threshold for each of a plurality of packets included in one measurement slot;
• and
• a communication state identification step of identifying any of a communication-enabled state or a communication-disrupted state in units of the measurement slots based on a determination result for each packet determined in the first threshold determining step, wherein
• in the communication state identification step,
• a current measurement slot is identified as being in a communication-disrupted state when a previous measurement slot immediately before in chronological order is in a communication-disrupted state and when all packets fall below the first threshold in the current measurement slot as an identification target,
• the current measurement slot is identified as being in a communication-enabled state when the previous measurement slot is in a communication-disrupted state and when one or more packets rise to equal to or more than the first threshold in the current measurement slot,
• the current measurement slot is identified as being in a communication-enabled state when the previous measurement slot is in a communication-enabled state and when all packets rise to equal to or more than the first threshold in the current measurement slot, and
• the current measurement slot is identified as being in a communication-disrupted state when the previous measurement slot is in a communication-enabled state and when no packets rising to equal to or more than the first threshold are received in the current measurement slot.
