Methods and arrangements to handle non-queued commands for data storage devices, such as Parallel and Serial ATA hard drives, are disclosed. The gateway provides bearer paths for communication traffic between network segments via contexts. The present invention improves electron emission efficiency. The stored data are then processed using statistical analysis, yielding the entire key, or partial information about the key that can be used to accelerate a brute force search or other attack. In a further embodiment, a criterion used by the roaming terminals for attaching to a given base station reduces conflicts in the overlapping RF regions of adjacent base stations.
