Abstract
A wireless communication device is disclosed that is capable of performing efficient network searching. Specifically, by utilizing its location information and accessing stored cell information, the device can streamline searching. Further, if a full search is to be performed, the device receives information from multiple radio access technologies together, and processes the received information digitally in order to search the individual radio access technologies. In addition, the device is capable of performing efficient 4G searches by setting its RF module to capture information of multiple raster points simultaneously within a search band, and shifting the search band so as not to duplicatively search raster points.
