Antennas Used per Mode 73
In some modes, not all of the connectors are in use.
The following table defines which external antenna connectors
are used in which mode:
Note: When using 1x1 mode, either in WDS mode or in AP mode
using the 3CWE591 Omni antenna, only connector A is active.
This is the connector on the far right, looking at the AP with the
3Com logo facing you. No other connectors are active in this
mode.
When in WDS mode:
■
select 1X1 mode when peers are omni-directional,
distributed around the central node in a point-multipoint
link.
■
select 2X2 mode for a point-to-point link, using either the
3CWE596 or 3CW598 panel antenna. The antennas must
both point in the same direction, with one antenna rotated
90 degrees, in order for MIMO to function correctly.
Note: In 2x2 mode, the two outer connectors (A and C) are
active. The connector in the middle (B) is not active and should
not be used.
