A high speed data transfer system includes a WAU () which is utilized to provide high speed access to satellite transferred data. The system is configured such that a plurality of data utilization () may access the high speed data via wireless links to the WAU (). Advantageously, high speed data services may be provided to users without the users requiring individual satellite antennas.

Satellite based data transfer and delivery system

A high speed data transfer system includes a WAU ( ) which is utilized to provide high speed data access to satellite transferred data. The system is configured such that a plurality of data utilization devices ( ) may access the high speed data via wireless links to the WAU ( ). Advantageously, high speed data services may be provided to users without the users requiring individual satellite antennas.

A wireless access unit ( ) for providing an interface between a satellite communications system ( ) and a plurality of terrestrial user devices ( ) in a centralized or distributed architecture includes a spectrum allocation unit ( ) for dynamically allocating spectrum to the plurality of terrestrial user devices ( ) based on a spectral environment about the wireless access unit ( ). A spectrum scan unit ( ) scans the spectral environment about the wireless access unit ( ) and generates a spectrum signal indicative thereof. An environment understanding unit ( ) provides signal information corresponding to signal emitters in proximity to the distributed or centralized network. A spectrum table ( ) assembles data related to the spectral environment and the proximity emitters for use by the spectrum allocation unit ( ) in dynamically allocating spectrum.

Wireless access unit utilizing adaptive spectrum exploitation

A communications network (10) having a plurality of wireless nodes (12-28) distributed within a region of interest makes routing decisions based on terrain information for the region of interest. A link quality determination unit (54) determines the quality of individual node-to-node links within the network (10), based on the location of the nodes (12-28) and the terrain about the nodes (12-28). A path selection unit 58 then determines an optimal path through the network 10 based on the link quality information. In one embodiment, communications corridors (102) are defined as preferred subpaths within a network for use in connecting remote nodes.

Communications network having adaptive network link optimization using

A battery compartment (12) adapted to accommodate any of several different types of batteries (30, 32, 34). The compartment (12) includes a hollow region having a length equivalent to that of one or more batteries (31, 33, 35) and includes a positive contact (65) disposed at one end thereof. The compartment also includes a cap (14) adapted to couple to an end of the compartment (12) remote from the one end. The one end includes a first contact (65) and one or more additional positive contacts (63). The additional positive contacts (63) are coupled to anodes of diodes (64) having cathodes coupled to the positive contact (65).
