For hubs using the internal
antenna, it is recommended
that the device to hub distance
be limited to 25 m (80 ft). The
internal antenna has an oblong
coverage area and is most
appropriate for applications
where the hub is directly facing
the device(s), e.g. mounting on
the wall at the end of a hallway
of doors.
