Base station router for distributed antenna systems
Certain aspects are directed to a base station router disposed in a distributed antenna system. The base station router includes a backplane and a controller. The backplane can manage an availability of sectors for coverage zones. Each sector can include communication channels to be radiated to mobile devices in the coverage zones and can represent an amount of telecommunication capacity. The controller can respond to a traffic indicator by causing the backplane to redistribute the availability of at least one sector. The sector can be redistributed from a first coverage zone to a second coverage zone.
