Abstract
A network device includes a HomePNA modem and means for synchronizing its clock with clocks of other HomePNA modems in the network in order to communicate at a higher frequency band. In one embodiment, the synchronization is with pilot signals. In another, it is by correcting for clock differences. The upconversions may be via oversampling or via analog mixing. The downconversions may be via subsampling or via analog demixing.
