Certain aspects are directed to a capacity optimization sub-system for a distributed antenna system. The capacity optimization sub-system includes a switch matrix and a controller. The switch matrix includes variable attenuators and switches. The switch matrix can receive sectors from base stations. The switch matrix can provide the sectors to coverage zones. The controller can communicate with the switch matrix. The controller can determine that a number of wireless devices in one or more of the coverage zones is outside a specified range of threshold traffic levels. In response to determining that the number of wireless devices is outside the specified range of threshold traffic levels, the controller can configure one or more of the variable attenuators and corresponding switches to redistribute capacity among the coverage zones by, for example, increasing and/or decreasing capacity in one or more of the coverage zones.
