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;

    providing access to at least one of the following location techniques (A-1) through (A-5);

    (A-1) a first technique for locating a mobile unit (M1) of the mobile units by recognizing a pattern of wireless signal transmission characteristics, wherein said pattern of characteristics is indicative of a plurality of wireless signal transmission paths between the mobile unit M1 and each of one or more of the communication stations, (A-2) a second technique for locating a mobile unit (M2) of the mobile units, wherein at least one of the following steps (A-2-1) through (A-2-3) are performed;

    (A-2-1) determining a time difference of arrival (TDOA) from timing information of signals transmitted between the mobile unit M2 and the communication stations, (A-2-2) determining a timing advance (TA) location estimate for the mobile unit M2 using wireless signals communicated between M2 and at least one of the communication stations, and (A-2-3) determining a location of the mobile unit M2 using the TDOA, and the TA location estimate, (A-3) a third technique for locating a mobile unit (M3) of the mobile units, wherein a first measurement for a time of travel of a signal transmitted by a wireless transmitter not supported on the earth'"'"'s surface is received by the mobile unit M3, wherein the first measurement is used for determining the location of the mobile unit M3, (A-4) a fourth technique for locating a mobile unit (M4) of the mobile units by using a value indicative of a signal strength of one or more signals communicated between the mobile unit M4 and the communication stations, and (A-5) a fifth technique for locating a mobile unit (M5) of the mobile units by using a joint probability from location related information obtained from each of two different location providing information sources, 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 (I1,1) of at least one the plurality of products or services according to both;

    (a) one or more characteristics of the instance I1,1 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 (L1) for accessing the instance I1,1 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 L1;

    wherein the route R is determined using a geographic location (L2) providing access to an additional instance (I1,2) of one of the plurality of the products or services (DI), wherein the additional instance I1,2 is determined according to one or more characteristics of DI identified by the first preference information, and the geographic location L2;

    outputting, for the first mobile unit, a first of the presentation data (P1,1) providing information for accessing the instance I1,1 additional presentation data (P1,2) providing information for accessing the instance I1,1, and the route R.
