This is totally impractical except for fixed devices that could be
precisely aligned and that remained immobile unless the standard is
referring to a light guide enclosed in an opaque enclosure. If the
optical devices communicate through the air, in order to be functional these devices must accept optical radiation from a cone of view (30 degrees for IrDA).
As a result, this requirement is meaningless as a method for securing optical wireless devices.
If this requirement is interpreted literally, these communicating
devices are no longer operating wireless, but are communicating through a shielded path that connect the devices. | |
