A portable computing device includes a radio frequency (RF) wired link, a data wired link, a core module, a plurality of multi-mode RF units, and a plurality of data modules. The core module is operable to communicate control information with one or more of the plurality of multi-mode RF units in a first frequency band via the RF wired link. The core module is further operable to communicate data of a wireless communication with one or more of the plurality of multi-mode RF units in a second frequency band via the RF wired link. The core module is further operable to communicate clock information to the plurality of multi-mode RF units in a third frequency band via the RF wired link.
