Cellular communication systems have traditionally been designed according to the paradigm that base stations serve independent sectors for which inter-sector interference should be minimized. Further, multiple base stations serving multiple sectors are traditionally grouped into a minimum number of sites, in order to reuse infrastructure for cooling, battery backup etc. and minimize site rental cost. Considering the current evolution of mobile communications, however, both the paradigm of avoiding interference and that of minimizing the number of sites may have to be revisited.
