Abstract: A cellular telephone system is described of the type wherein a plurality of contiguous cells, each having an assigned set of identification codes, are arranged with means for maintaining continuous communication with mobile telephones moving from cell to cell. The system allows multiple access by including means for assigning at least one of the in the assigned set of identification codes to more than one mobile telephone. A unique identification code is assigned to a mobile telephone located in the cell. A signal having a unique identification code is generated for identifying the mobile telephone. The signal is coupled to the zones. A combiner is also provided for combining signals from all of the zones in the cell. A receiver is coupled to the combiner for retrieving the signals having the code. According to another aspect of the invention, the signal coupled to the zones is delayed so that the transmission of the signal among the plurality of antenna sets is delayed by a preselected amount so as to reduce interference caused by successive reception of signals.

Abstract: A computer-implemented modeling tool for cellular telephone systems predicts signal strength under real conditions within a building, by considering the effects of inter-building and intra-building structures on transmitted signals. The modeling tool gives more accurate predictions under line of sight conditions, when obstructions occur due to inter-building and intra-building structures.

Abstract: A zoned microcell system with sector scanning for cellular telephone systems has a plurality of contiguous cells, each having a different assigned set of transmission frequency channels, arranged with handoff means for maintaining continuous communication with mobile telephones moving from cell to cell. The system includes at least one cell having a plurality of transmitting and receiving antenna sets. Each set is positioned at a respective antenna sub-site within the periphery of the cell at a suitable location, and is configured so that propagation and reception of signals is limited to a transmission zone which is substantially within the boundaries of the cell and which is substantially less in area than the cell. Control means monitor the strength of the signal received by each of the antenna sets at each frequency channel in the assigned set. Transmission, at each frequency channel in the assigned set, is confined to the antenna set at one sub-site in the cell having the strongest received signal at each frequency to thus limit signal propagation to the transmission zone served by that set. In one embodiment, further signal strength monitoring is provided at each sub-site. Transmission, at each frequency channel in the assigned set, is confined to a specific sub-set of antennas at the sub-site. In this way, transmission at each frequency channel in the assigned set is confined to a limited sector within the transmission zone.
