Abstract
One or more short-range base stations in a network environment provide a substantially smaller coverage area than a long-range base station. The coverage area provided by each of the short-range base stations fully resides within or at least partially overlaps with the coverage provided by the long-range base station. Handoffs from the long-range base station to a respective short range base station, and vise versa, can be conditional on any number of one or more factors such as a speed of a mobile device through the network environment, a type of application and/or type of data transmitted over a respective communication link between the mobile device and the long-range base station, presence of one or more radio frequency layers in the network environment, mapping of a location of the mobile device to a speed limit value derived from a geographical map, etc.
