1. A wireless communication device comprising:
- beam-steering circuitry; and
a directional antenna coupled to the beam-steering circuitry, wherein a reflector positioned on either a wall or a ceiling spaced away from the directional antenna reflects millimeter-wave signals communicated between the directional antenna and one or more secondary wireless communication devices of an indoor wireless personal area network.
