| 1. An automated method of downloading data from a central host to multiple remote wireless devices, the method comprising:
transmitting a first message from the host to each of the multiple remote wireless devices, the first message identifying
a predetermined download time for a data download to the remote wireless devices such that the remote wireless devices can
prepare to receive the data download;
automatically determining which of the multiple remote wireless devices did not receive the first message;
transmitting at least one second message from the host to each remote wireless device that did not receive the first message,
the second message identifying the predetermined download time for the data download; and
substantially simultaneously broadcasting download data from the host to the multiple remote wireless devices such that the
multiple remote wireless devices receive the download data from the host substantially simultaneously and store the download
data,
wherein the first and second messages are usable by the multiple remote wireless devices to set calendar reminders in the
multiple remote wireless devices for powering on or entering an active state allowing the download data to be received.
