A radio transceiver device includes circuitry for radiating
electromagnetic signals at a very high radio frequency both through
space, as well as through wave guides that are formed within a substrate
material. In one embodiment, the substrate comprises a dielectric
substrate formed within a board, for example, a printed circuit board. In
another embodiment of the invention, the wave guide is formed within a
die of an integrated circuit radio transceiver. A plurality of
transceivers with different functionality is defined. Substrate
transceivers are operable to transmit through the wave guides, while
local transceivers are operable to produce very short range wireless
transmissions through space. A third and final transceiver is a typical
wireless transceiver for communication with remote (non-local to the
device) transceivers.
