1. A method for communicating information to a plurality of mobile units, wherein for each of the mobile units, wireless signal measurements are obtained from transmissions between the mobile unit and a plurality of terrestrial communication stations, and wherein each of the mobile units is independently moveable from each of the communication stations, and each of said communications stations includes one or more of: a transmitter for transmitting wireless signals to the mobile units, and a receiver for receiving wireless signals from the mobile units, comprising: receiving, for a first of the mobile units, first input for determining first preference information, the first preference information for determining, for one or more of a plurality of products or services, corresponding presentation data for providing one or more corresponding presentations to the first mobile unit; first obtaining a first estimate indicative of a location of the first mobile unit, wherein one of the location techniques (A-1) through (A-5) is used for locating the first mobile unit; identifying, using the first preference information and the first estimate, an instance (I 1,1 ) of at least one the plurality of products or services according to both: (a) one or more characteristics of the instance I 1,1 identified by the first preference information, and (b) a result from a first condition dependent upon both: (b-i) location data identifying a corresponding geographic location (L 1 ) for accessing the instance I 1,1 , and (b-ii) the first estimate, or a location along an expected route of the first mobile unit determined using the first estimate; obtaining a route (R) to substantially the geographic location L 1 ; wherein the route R is determined using a geographic location (L 2 ) providing access to an additional instance (I 1,2 ) of one of the plurality of the products or services (DI), wherein the additional instance I 1,2 is determined according to one or more characteristics of Di identified by the first preference information, and the geographic location L 2 ; outputting, for the first mobile unit, a first of the presentation data (P 1,1 ) providing information for accessing the instance I 1,1 , additional presentation data (P 1,2 ) providing information for accessing the instance I 1,1 and the route R.
