Abstract

A distributed antenna network for reducing multicast interference between multicast cells. More particularly, a system and method are provided for calculating multicast interference zones between the multicast cells and configuring coverage areas to encompass the multicast interference zones. This multicast cell configuration avoids the need for delay time adjusting techniques for equalizing the transmission paths and reduces multicast interference by effectively shifting the multicast interference zones.
