In some implementations the passive signal combiners comprise a set of planar waveguides (e.g., which may be referred to as beamformers or Rotman lenses) that have multiple inputs and outputs and are configured to provide orthogonal output signals.

Here, a transformation of the electrical signal by a given passive beamformer may have a first resolution, and outputs from the passive beamformers may correspond to orthogonal groups. A combiner circuit may be used to combine the outputs from the passive beamformers and produce a combined output having a second resolution and an associated error. In some aspects, this error may be less than a cumulative error associated with the passive beamformers if a single passive beamformer was instead employed to transform the electrical signal at the second resolution. Also, by using at least partially different bandwidths for components in the circuits, a higher effective bandwidth for the transformation may be achieved.

A position coordinate based route transmitted from a server is reconstructed as a route of link numbers or node numbers in map data of navigation apparatus without error. A route guidance server searches a route from a start point to end point designated by a navigation apparatus; selects all or a part of nodes included in the searched route as route nodes; sets complementary points to the respective selected route nodes on the route and at a distance longer than a predetermined distance from the respective route nodes; and transmits information including coordinate information on the route nodes and complementary points as route information to the navigation apparatus. Then, based on the coordinate information on the route nodes and complementary points transmitted from the server, the navigation apparatus identifies the route nodes and road links connecting the route nodes by identification numbers in map data the navigation apparatus it self has.

A method of distributing map data from a map server to a wireless communications device entails generating a bitmap array representative of the vector map data for a given zoom level, computing attributes of the bitmap array to determine which map features to retain and which map features to suppress, and then transmitting to the wireless device only the map data for the map features to be retained. By counting the number of bitmap cells representing a polygonal map feature such as a park, lake, or island, the approximate area is quickly estimated. If the area falls below a threshold, the map data for the small polygon is discarded. Similarly, if a polyline map feature overlaps (or is too proximate to) another polyline map feature, one of the polyline map features is discarded. The map data actually transmitted is thus reduced, thereby economizing bandwidth without unduly sacrificing map detail.
