Abstract: Wi-Fi-based location determination methods may include receiving location information and/or identifier information regarding a Wi-Fi hot spot, at a database. The methods may include transmitting the location information and/or identifier information regarding the Wi-Fi hot spot, from the database to a positioning receiver. Related systems are also described.
Abstract: Processes of selecting a content delivery method may include selecting between first and second content delivery methods for a particular media content in response to demand for the particular media content by a plurality of customers. Related systems and devices are also described.
Abstract: Digital data broadcasting is performed by analyzing propagation characteristics in a broadcast propagation area to determine a rebroadcasting strategy. Data packets are broadcast, and at least one of the data packets is selectively rebroadcast, to broadcast receiving stations in the broadcast propagation area according to the rebroadcasting strategy that was determined. The analyzing, broadcasting and selectively rebroadcasting are performed independent of receiving acknowledgements that data packets have or have not been received. The rebroadcasting strategy may be determined by measuring a received signal quality of broadcast data packets at multiple locations in the broadcast propagation area and/or by simulation of the propagation characteristics based on a model of the broadcast propagation area.
Abstract: Selected data packets that were broadcast over millimeter microwave frequencies to millimeter microwave receiving stations in a millimeter microwave broadcasting system footprint are rebroadcast. Rebroadcasting is selected based upon an indication that is received from a subset of the millimeter microwave receiving stations, that the one or more data packets were not received successfully by the subset of the millimeter microwave receiving stations. Selective rebroadcasting may be performed based upon statistical analysis of indications that are received from the subset of the millimeter microwave receiving stations.
