Abstract

In embodiments of the present disclosure improved capabilities are described for increasing the bandwidth in a large area broadband network where an optimization server is incorporated within the wireless network in association with the public data network gateway, which may be deployed in regional areas, thus reducing the time-latency for applications being run from a mobile cellular device. Further, by associating additional optimization servers at base stations, application functionality may be optionally transferred from the regional optimization server to the local base station optimization server in instances where a number of mobile cellular devices are requesting the same data via their access through the same cell, and in other instances, to the effect that back haul network bandwidth utilization is reduced or eliminated.
