Abstract
A tag stores information identifying the sequence in which it received wireless signpost signals from different signposts. In another configuration, a tag maintains data identifying a group of signposts that are to be treated as equivalent. In yet another configuration, wireless signpost signals transmitted by each of a plurality of signposts all contain the same signpost code. In still another configuration, a signpost has an interface through which a signpost code of the signpost can be selectively set.
