A wireless access network is based on a two-tier access point (AP) structure to provide effective and efficient wireless communication into an individual home / office building. A first tier of the network utilizes “neighborhood” APs, relatively low power, and utilized to provide wireless communication with a “nanocell” boundary (e.g., 300-1000 feet). A second tier of the network utilizes a set of “network concatenation devices” (window bridge), with a separate network concatenation device at each permanent facility in the nanocell that houses wireless devices. The network concatenation device is attached to a window, for example, of a home in communication with the neighborhood AP. The network concatenation device functions as a bridge to couple to each of the wireless devices within the home. This communication is then relayed in an efficient manner between the network concatenation device and the neighborhood AP. By using a number of neighborhood APs, rather extensive wireless coverage can be obtained.

A computer system provides the ability to construct and edit a Data Definition File (DDF) containing hierarchically related elements of data, some of which are dynamic in that they must execute in order to produce or retrieve data. A client computer system having knowledge of a DDF appropriate for its uses sends a request to a server, which contains or can retrieve the DDF requested by the client. The request contains parameters used by the server to customize the resulting keyed data file for the client's purposes. Upon receipt of the request, the server copies the DDF into a coupled memory, performs requested parameter substitutions, and executes dynamic elements to produce resulting data elements. The process is repeated recursively for all elements of the hierarchical structure, until no dynamic elements remain, then the resulting keyed data file is returned to the client for its uses. Data elements may be derived from a plurality of sources, and these sources may be combined and manipulated using a plurality of data operations, including relational algebra or structured query language, enabling joins and merges between multiple sources and formats. An Authoring System is provided which assists in the construction and validation of DDFs.
