An integrated system is described. This integrated system includes: a radio node that communicates using a cellular-telephone communication protocol; and an access point that communicates using an IEEE 802.11 communication protocol. Moreover, the integrated system includes a housing between the radio node and the access point, where the housing provides mechanical coupling and electrical coupling between the radio node and the access point, and the housing provides electrical power and data to the access point from the radio node. For example, the housing may provide the electrical power and the data using a PoE cable. In some embodiments, the radio node dynamically modifies the electrical power provided to the access point or receives, from a controller, an instruction specifying the electrical power to be provided to the access point.
