A DBS distribution network (100, 90) is modified with a secondary transmission bi-directional capability below 950 MHz by adding filters to separate modified mobile-communications (60) frequencies from typical DBS services. DBS subscriber termination points function as extremely localized ultra-miniature cell sites within a building. Third generation (3G) cellular networks and second-generation (2G) cellular networks are together merged with DBS networks. The modified network simultaneously handles traffic in known and future cellular air interface standards such as: UMTS, GSM, TDMA, CDMA. Cellular mobile radio terminals do not have to be modified. Signals traverse on non-utilized DBS frequencies. DBS active elements are modified, and new components are provided.
