A femto cell access point device (FAPD) selects channel bandwidth and frequency for transmission based on bandwidth of a broadband channel between the femto cell and a core network. A method can include determining a data throughput associated with a broadband channel communicatively coupling the access point device and a network device of a network, and evaluating channel information associated with a plurality of frequency sub-bands. The access point device can be configurable to communicate over the plurality of frequency sub-bands. The method can also include selecting a transmission parameter for a mobile device, wherein the selecting is based on the data throughput, and wherein the transmission parameter comprises information representing a selected set of the plurality of frequency sub-bands. The broadband channel can be a digital subscriber line (DSL) channel in some embodiments.
