Abstract: A method has been provided for automatically defining the communication services available to a potential subscriber on the basis of street address. The method is able to provide rate center information in response to the submission of a street address. The method is especially advantageous when applied to fixed-position wireless systems, such as AT&T's Fixed Wireless System (FWS), where the additional complication of determining the radio frequency (RF) coverage available to subscribers is involved. The method determines the base station associated with the street address and applies the business rules of that station to a new subscriber to determine service availability. The RF coverage and business rules determinations are made in response to the submission of a street address. A system for determining service availability in response to the submission of a subscriber address has also been provided.
