发明名称 Distributed antenna personal communication networks system
摘要 A distributed antenna PCN system provides for telephone service on a CATV network. The PCN antenna signal from one PCN node is transported to more than one remotely located antenna nodes via the cable. Thus, rather than having a PCN cell shape equal to the radiation pattern of one antenna node, a distributed antenna system creates a cell shape having a distributed pattern, equal to the sum of the radiation patterns of the individual antenna nodes. A single PCN cell is then not necessarily a contiguous area but may include a number of geographically separated areas so that subscriber locations which are not physically adjacent may be included in the same cell. Therefore, the CATV operator may offer universal service to all subscribers in the CATV system using a first PCN node and add subscribers to the first PCN node as needed, regardless of subscriber location.
