Abstract: A periodic wireless data transmission has improved access latency obtaining information regarding users' interest in the information and by arranging the information on an transmission in order of descending popularity. In one embodiment, each adjacent pair of topics on the transmission. The topics' positions on the transmission are exchanged if the exchange decreases the average latency for all users. This may be repeated for all of the topics on the transmission. The transmission structure may also be arranged so that the transmission combines a number of transmission channels to obtain greater aggregate capacity. This may be done using, for example, an FDMA transmission structured to be theoretically comparable to a plurality of “striped” disks known as a RAID (redundant array of inexpensive disks).
