1. A method for offloading autonomous vehicle (AV) data to a download pole, the AV comprising a transceiver, and the download pole comprising a transceiver, the method comprising:
identifying, by the AV, the download pole in a parking spot that is close to the AV;
establishing a short range wireless link between the AV and the download pole;
positioning the AV so that the transceiver of the AV is aligned with the transceiver of the download pole based on instructions received over the short range wireless link from the download pole; and
establishing a first link between the transceiver of the AV and the transceiver of the download pole,
wherein establishing the first link comprises:
comparing a message received over the short range wireless link with the same message received over the first link;
measuring bit error rates for the first link by comparing the message received over the first link with the message received over the short range wireless link; and
adjusting the position of the AV to result in a better alignment of the transceiver of the AV with the download pole to reduce the bit error rates.
